Storplex 2008 FUJITSU Storage System

1. What is Storplex 2008?

The role of storage has changed significantly from the 20th to the 21st century, and now storage has grown to be the core of IT infrastructure supporting corporate management. Fujitsu in focusing on the increasing importance of storage is proposing storage as a new type of system comprised of application and middleware rather than any single component. From now on, Fujitsu’s new storage concept, Storplex2008, is being developed to resolve changing operational problems. As a Cineplex provide a variety of movies in one building, Fujitsu's Storplex aims to deliver integrated solutions to customers with a focus on the different requirements of each operation. The concept of Storplex 2008 presents a path to such optimal applications based on high-level storage related technologies that Fujitsu has developed over the past 10 years. These include: "Flexible connectivity”, "Dynamic scalability”, "Continuous data access", and "Enterprise storage management”. Behind the creation of this concept are the following storage environment changes of recent years:

Globalization of business activities Globalization of business activities continues to accelerate due to advances in, and deregulation of the internet. In order to ensure smooth continuous business, day and night, IT infrastructure must also provide stable operation 24 hours a day, every day. System availability and new operation frames are necessary to guarantee this business continuity.

Increasing corporate social responsibilities

Healthy corporate management based on laws and regulations is necessary for the stable growth of each company. In Japan and around the world, Financial Products Trading Laws have come into effect. These stipulate internal controls for business processes. Aimed at maintaining shareholder trust

they must be established and controlled and their validity must be proved. At the same time security enforcement is also essential. Systems free from information leakage, caused not only by external data access but also by internal malicious activity, must be established.

Worsening environmental problems With the first commitment period of the Kyoto Protocol beginning in 2008 (during which obligated reductions in greenhouse gases must be achieved), companies must seriously tackle environmental concerns. IT infrastructure is deeply related to global warming. In particular data centers with their concentration of servers and storage pose serious power consumption problems. In order to create reliable products, power savings and CO2 reductions have become fundamental corporate activities. This trend will continue to accelerate in the future.

Explosive increases in data volumes Though nothing new, the amount of data keeps increasing. For example, data that was previously stored in individual personal computers is now integrated into file servers for security and other reasons, expanding storage requirements. Internal controls also cause upsurges in the amount of data, such as log files that are required to be saved. Also, from the standpoint of management accounting, storage of payment statements has become common. As a result, enormous data growth is having a heavy impact on storage. In addition to storage capacity expansion therefore, new measures are required that consider cost reductions and efficiency of operation.

Increases in “unstructured” data Previously, it was only structured data that was held in storage and managed by database systems. As the internet spread, all employees were assigned personal computers to raise business

3


productivity. As a result office documents and e-mail exchange rapidly increased with the acceleration of business. Along with business documents created in Excel, Word, PowerPoint and mail documents vital to communication, more unstructured data such as PDF files, images from digital cameras, scanned images, audio files, large capacity video files, internet web site content, and production and engineering design drawings, have also been increasing rapidly. In future storage operation management will be need to manage storage operations in an appropriate and effective manner. It must anticipate the needs of information management and information utilization, including unstructured data use to ensure improved business productivity and strengthen corporate competitiveness.

Overview of Storplex 2008 "Storplex 2008" focuses on five key areas in order to respond to the changes surrounding business organizations, storage environments and to find solutions to new problems. They are: "Business continuation", "Security and compliance", "Lifecycle management", "Information sharing and retrieval" and "Green products". Fujitsu will continue to provide storage systems that comply with these five key areas on an on-demand basis.

fig.1

Business continuation Storage systems are part of the fundamental IT infrastructure for business continuity in terms of storing and providing "information" as a crucial management resource. ETERNUS enables business continuation from the standpoints of "data protection" and "data disaster recovery.”

Security and compliance Security is guaranteed through secure storage management, data encryption and encryption key management. With compliance, access through a dedicated API and falsification prevention functions protect contents.

Lifecycle management Fujitsu helps customers make effective investments in storage through the placement and movement of data between suitable storage media. This is keyed to the value of the information as it changes across in the various stages of its lifecycle.

Information sharing and retrieval Integration of scattered file servers using file virtualization functions enables information sharing and improved data retrieval. Further, parallelization functions which use multi-cloning and the sharing of widely dispersed files, enable high-speed full-text searching of unstructured data types.

Green products Through the development and use of storage products that have fewer effects on the environment, Fujitsu is contributing to reductions in environmental burdens. Fujitsu's green products also prevent wasteful power consumption through effective storage use and promote energy conservation.

2. Business Continuation

(Secure and stable operation of/Disaster prevention for the IT system)

Business continuation is an extremely important issue and has always been required by some customers. IT has become so vital in corporate activity that an IT system halt can directly links to a loss of business opportunity. At the same time, IT system halts also pose the risk of damaging corporate image and lose of brand value. In order to prevent such problems from occurring Fujitsu continues to make great efforts to improve system availability by adopting highly reliable components and redundant configurations for its storage. In addition plans are necessary to ensure smooth business operation in the event of a system halt due to disaster or terrorism. Such plans must be able to minimize damage and ensure immediate recovery from such damage. Stable business continuation is also essential from the perspective of compliance and very important in expanding global business and improving corporate image. Storage systems are therefore fundamental IT infrastructure for business continuation and must always store and providing "information" that is a crucial management resource. ETERNUS supports business continuity from the standpoints of "Data Protection" and "Disaster Recovery".

fig.2

2-1 Data protection Hardware data copying and data protection through links with databases provide methods of "data protection". Fujitsu is also developing CDP (Continuous Data Protection) solutions.

Hardware data copying Stored data backup is a necessary business operation. However, it can pose problems that affect business operations. These problems are solved by Fujitsu's AdvancedCopy function (high-speed copy function) which allows data copying at any given point in time without stopping business operations.

EC (Equivalent Copy) function This function simultaneously creates copies as the original data is updated. Ostensibly a mirrored relationship, when the relationship is broken the previously duplicated data can be used for other business processes and for backup to tape devices.

OPC (One Point Copy) function This function creates a copy of all the original data at any given time. The data image, at time the copy instruction is issued, is duplicated and can be used for other business processes and for backup to tape devices.

QuickOPC function This function is used to create a copy of all the original data, and then only copy the updated part of such data. This function is suitable for backup of large-scale databases that require a shorter backup time.

SnapOPC function This function is used to create a copy of the data present before each data update. This approach can save copy destination disk capacity and is suitable for backup up of file servers that have relatively small updates.

fig.3

Data protection through a link with databases

AdvancedCopy provides efficient database duplication processing (mirroring). Since AdvancedCopy can mirror data at the hardware-level, it can reduce the CPU load of the database server. Validation tests using Symfoware, Fujitsu's own RDBMS, have proved that CPU load can be reduced from approximately 20% to 6%.

fig.4

fig.5

Continuous data protection solution CDP (Continuous Data Protection) is a new type of data protection method that saves updated content, in chronological order every time data is updated. This method guarantees continuous data protection.

fig.6

2-2 Disaster recovery "Disaster recovery" provides data mirroring between remote sites using either a 1: 1 or 1: n ratio.

Remote mirroring For Oracle DB, ETERNUS SF Recovery Manager for Oracle, in conjunction with ETERNUS hardware data copy function ensures that backup can be taken while integrity of the data file (tablespace), and control and archive log files are guaranteed.

It is useful to distribute data between several sites in an IT system in order to handle disasters. Fujitsu has validated remote mirroring using WAN, and has made it possible to construct highly reliable, highly

6


efficient disaster recovery systems even in remote locations. Fujitsu also supports remote mirroring via iSCSI connection, which allows disaster recovery systems to be constructed at lower prices. Now Fujitsu is developing a function for low quality transmission lines (Disk Buffered REC) that allows remote mirroring even over transmission lines with low or fluctuating frequency bands.

fig.7

Remote copying to multiple branch offices

Fujitsu is enhancing its remote copy functions so that data copy destinations can be set flexibly to distribute data effectively. This enhancement achieves higher level disaster control by distributing data between multiple data centers.

3. Security and Compliance

Storage faces security threats because it not only stores information, but it is the place that is accessed for that information. Protection of storage and stored information is a necessary compliance function.

Demand for security has increased dramatically in the 21st century. Beginning with the SOX act implemented in the USA in 2002, the personal information protection law in Japan in 2004 and Financial Products Trading Law (Japanese version SOX act) in 2008, all urge or command companies to comply with security regulations. Security and compliance have also become necessary with the globalization of business activities and are significant components in corporate responsibility.

fig.9

3-1 Secure storage management (against external attacks) Storage is moving from servers to devices directly

connected to the network. In such environments storage systems are even more subject to threats, including unauthorized access, information leakage, internal fraud, and data destruction.

Secure data paths from servers and access path management are required for operational storage security and management. Monitoring of storage management is important in preventing unauthorized access. Segmentation of access authority is also essential in further restricting access methods. As well as simply granting certain levels of account authority to end users to allow them to operate a large shared system using large equipment, Fujitsu offers various functions to deal with the associated issues and suggests ways operations should be conducted.

Fujitsu believes that the following four values must be provided to customers: - Robust protection from external attacks - Controls that stop internal attempts to remove or alter data.

- Information reliability (Information leakage prevention and authenticity assurance)

- Information storage beyond individual device life-spans. Secure storage management, data encryption and encryption key management ensure security. In terms of compliance, access via a dedicated API, falsification prevention functions, media refresh functions (for long term storage) and access through standardized inter-corporate protocols are keys to content protection.

fig.10

3-2 Data encryption and data key management

Data encryption is one effective measure in preventing information leakage. ETERNUS has internal functions that can encrypt each LUN using AES algorithms (Advanced Encryption Standard: a United States standard information processing algorithm for encryption. This algorithm has been approved to be included in the "e-Government Recommended Ciphers List" by Ministry of Internal Affairs and Communications and Ministry of Economy, Trade and Industry). Even if a disk is removed by a malicious third party or lost during maintenance work, the encrypted disk cannot be decrypted. Also, many information leaks are due to stolen tapes. Many of have seen news reports about such stolen tapes. In order to prevent this type of information leakage, Fujitsu provides both a tape encryption function and also a function that prevents removal of unencrypted tapes from the tape library. Furthermore, Fujitsu focuses on the importance of key management and provides encryption key management servers. Through these efforts Fujitsu is working to realize encryption key lifecycle management that complies with each corporate policy.

fig.11

3-3 Information reliability/information leakage prevention

Now, storage capable of storing fixed content that cannot be falsified or changed is required as a security compliance measure. In order to archive fixed content safely and over the long term, a new type of storage product called CAS (Content Aware Storage) has been developed. CAS accesses content through a dedicated API (Application Programming Interface) for secure information archiving. Authentication by a dedicated API allows only users permitted access to read and write data and prevents information leaks by unauthorized users through illegal access. Fujitsu is developing products that are based on XAM (eXtensible access method: specification defined by SNIA, which regulates interfaces between reference information and storage areas). XAM, used as a content access API, provides methods for accessing fixed content defined by each storage vendor and for sharing interfaces between middleware that accesses content. XAM allows the referencing of content between different middleware and storage.

fig.12

3-4 Media refresh (information storage beyond device lifetime)

Some data needs to be stored longer than the lifetime of the storage device. This is becoming more common in meeting legal and regulatory audit requirements. Automatic data migration from old to new media is required. Media refresh allows long-term data storage without concern for media service life.

fig.13

10


4. Lifecycle Management

(IT investment optimization through the lifecycle)

"Information Lifecycle Management (ILM)" - an approach to managing the flow of information from creation, utilization and management- is receiving increasing attention.

Automatic storage in the most suitable environment, such as Tiered Storage and automatic placement of files based on policies is key to effective lifecycle management. It also realizes cost reductions and enables effective long-term storage of information. Amid an explosive increase in data distribution and

the rapid spread of broadband environments, the amount of data companies are dealing with has been said to be increasing at an annual rate of 70%. Furthermore, compliance with laws and regulations obligate longer-term data storage. The rapid increase in unstructured type data also cannot be ignored either. Most conventional data corresponds to a database table structure, but in recent years enormous quantities of unstructured data, such as mail documents, business documents created using office applications, images, PDF documents, audio files, and video files have become ubiquitous. Equally managing the various data types is becoming harder due to cost and the manual nature of their management. Lifecycle management solves these problems by managing information depending on its life “stage”. The value of information is highest when information is in its "create" and "use" stages and changes as it moves into the "reference", "save" and "delete" stages. Fujitsu enables effective investment in storage devices through data arrangement and by migration to the most suitable storage device as data value changes.

fig.15

4-1 Tiered storage Here storage is created using different media tiers. Information is automatically stored in the appropriate tier according to its value and lifecycle management policy.

Tiered storage structure Storage is divided into groups according to performance and cost. This allows stored information whose value has changed to be moved to more cost effective storage. Here storage has been divided into the following three groups called Tier1, Tier2, and Tier3: Tier1: Online high performance storage capable of

high-speed update and retrieval Tier2: Nearline storage that has larger capacity with

excellent cost performance Tier3: Offline storage with very large capacity ideal

for long term low activity data storage

Policy based optimal placement of files Files are automatically transferred to where they should be stored based on mapping between their information value and tiered storage. fig.14

11


For example, a "*.BAK" file is a backup file before update so it is arranged in Tier3 from the beginning. But placement is important. If a file is not accessed for a month, policy may move it to Tier2 from Tier1, based on its access frequency. It the access frequency declines even further, then it may be moved from Tier2 to Tier3 and the file automatically deleted after its storage period expires.

fig.16

Autonomous data migration and device transfer

fig.17

4-2 Transparent access from applications

Even if data stored in tiered storage is repeatedly rearranged, applications do not need to know in which tier of the storage data is stored. Transparent access from each application is always guaranteed.

Data is automatically reorganized whenever a new storage device is installed. When a new device is installed, tiers will be defined for the new device. At the same time, definitions can be made to arrange new target data in the new device and files can be migrated from old tiers to new tiers. Once all data is rearranged in the new device, the old device can be deleted from the volume set.

5. Information Sharing and Retrieval

(Prompt strategic utilization of cross-sectoral information (aggressive business management))

Information is not just something to be stored, it needs to be utilized for enhanced corporate competitiveness. But with the emergence of unstructured data types, the amount of information is not only increasing at an accelerating rate but new mechanisms, for information sharing and retrieval, are necessary. Integration of scattered servers is gaining a lot of attention as a solution. As the amount of unstructured data increases, additional file servers are frequently installed. File servers are easily utilized by connection to networks. However as the number of file servers increases, it becomes more difficult to manage mount points and client access authority. In addition adjusting and securing system maintenance times, amenable to all clients, becomes problematic. File server integration by file virtualization solves these issues. File sharing between widely separated sites and high-speed full-text search for unstructured type data also play important roles in information utilization.

fig.19

5-1 File virtualization function

Unified mount point for multiple file servers

The file virtualization function combines multiple file server name spaces into one big name space under the switching layer. This big name space is a Global Name Space. Scattered mount points are integrated into one, allowing all clients to share all name spaces.

fig.20

Benefits of file server integration The file virtualization function can move files between file servers without effect on applications. It does this by hiding physical servers and storage groups from the applications. Smooth data migration becomes possible without affecting client operations. Data can also be mirrored by the replication function and if the primary server fails, the secondary file server can take over the primary server's load. Again the virtualization means such a device failure has not affect on the clients at all. File virtualization is an important method of

integrating multiple file servers. A further advantage is that load balancing of multiple file servers can improve overall system performance.

13


5-2 Wide area file server integration (Wide area contents sharing)

The scattered file servers to be integrated are not necessarily all located on a LAN. They may be located in an extremely broad area including overseas. With such wide areas response degradation of Windows shared files (CIFS) in WAN needs to be improved. Fujitsu can create an environment close to LAN for wide area connections and accelerate file integration through WAN optimization and other high-speed solutions. Fujitsu also supports TCP applications (FTP, HTTP, NFS, MAIL, etc.) in addition to CIFS and provides optimized WAN networks for variety of customers.

fig.21

5-3 Parallel search using the multi-clone function

Integration of file servers enables access to larger data volumes, making technology that can utilize it more important. With conventional data types, data retrieval is mainly performed using search keys prepared at time of database design. But search technology called “full-text search” is required for unstructured data types. Parallel search using the multi-clone function is equivalent to full-text search. Here many clone volumes are created from the master volume by the multi-clone function with each clone volume assigned to a search server in a 1:1 relationship. This enables parallel searching on all search servers with data access at the highest possible throughput.

6. Green Products

(Approach to environmental problems)

Global environment problems are becoming increasingly serious. It is essential for companies to take an active approach to environment problems, such as compliance with environmental laws and regulations, prevention of environmental risks, and fulfillment of increasing social responsibilities. As the percentage of IT power consumption continues to rise, due to the widespread and increasing demand for IT devices, development of new power saving technologies is now an urgent task. Fujitsu commenced Green Policy Innovation in December 2007 aimed at reducing environmental impact by strengthening and promoting Green IT efforts, something that Fujitsu has spent years to achieve. Fujitsu is focusing on both "reduction of environmental burden imposed by IT infrastructure" and "reduction of environmental burden imposed by IT utilization," and offering products and services that take advantage of Fujitsu's knowledge and cutting-edge technology. Through the development and use of IT devices with fewer effects on the environment, Fujitsu will contribute to reduced environmental effect. Fujitsu is working to develop eco-friendly, user-friendly green products, and technology that improves energy efficiency by reducing storage capacity needs and power saving technology that controls wasteful power consumption.

fig.23

6-1 Space and power savings (user friendly)

Fujitsu has been making efforts to develop space and power saving, silent design storage devices. It released the ETERNUS2000 disk storage system in May 2007.

Power savings Through the adoption of cutting-edge technologies ETERNUS2000 consumes less power compared to older models. With twelve 300GB disk drives are installed in a ETERNUS2000, power consumption can be reduced by 2,100kWh a year compared to older models. If this is converted into CO2 emissions, it is equal to a reduction of 803kg of CO2, the amount absorbed by 58 cedar trees a year. In 2009 Fujitsu will achieve reductions in power consumption of about 20% compared to older models by using disk drives with better power-saving performance.

fig.24

Space savings In ETERNUS2000, the RAID controller is contained on a single chip, which reduces PCB size by 60%. A further 60% reduction in the number of components leads to a more compact and lighter storage device. Reductions in the number of

15


components also results in a lower failure ratio and improved storage device reliability. The minimum height of the ETERNUS2000 is 2U and this size is half that of previous models. If the ETERNUS2000 is introduced into a large-scale data center, substantial floor space and customer costs can be saved.

6-2 Improved operation efficiency New technology such as storage integration, Thin Provisioning, and De-duplication helps improve operation efficiency.

Going "Green" through storage integration

While the memory density of disk drives doubles on a two-year cycle, disk drive power consumption has stayed about the same regardless of the generation. For example, if 15TB of data stored on a disk storage system configured with 50 x 300GB online disk drives is migrated to a disk storage system supporting the latest 600GB online disk drives; the number of installed disks is reduced by half from 50 to 25, and power consumption also decreases by half. In addition, more efficient power saving is achieved by storing data on appropriate disk drives, based on data value and importance. Flash SSD (Solid State Disk) based on flash memory technology, can reduce power consumption further as it contains no mechanical functions.

Thin Provisioning (Dynamic Storage Capacity Allocation)

Thin Provisioning is technology that virtualizes storage capacity and enables efficient use of space. Users of individual servers are assigned virtual volumes according to their requirements but no physical storage is used at that time. Only when

data is written to a volume that physical storage is assigned pro rata to the user. In environments where Thin Provisioning is introduced, physical disk drives can be efficiently expanded by dynamically expanding physical capacity assigned to each volume. The following figure shows a total of 400TB virtual volumes are assigned to servers A, B, and C. The disk storage system can start operation with 100TB of shared disk drives in the storage pool (1/4th of the virtual volume size). The available space is assigned according to actual needed disk drive capacity. This technology realizes efficient use of storage capacity.

fig.25

De-Duplication (Detection and deletion of duplicated data)

De-duplication is technology that deletes duplicates and compresses data before storing it in a storage device. As individual user can share lots of data, much duplication can occur. There is also a lot of partially rewritten data, and data with different file names that contains the same content. In this case data undergoes detailed checks based on specified byte counts, and if data overlaps already stored data, the data is prevented from being written.

16


Further, MAID (Massive Arrays of Idle Disks) technology can perform power-saving operations in conjunction with backup operations. Backup destination disks can save power by only rotating during backup periods.

Some reports have shown that this technology can compress data size by 80% or more.

6-3 ECO visualization and operation (Cutting unneeded power consumption)

Fujitsu can centralize storage power consumption and visualizes it along with storage load information. This allows business usage to checked by storage load information and unnecessary storage operations detected. For example, if storage area 1 is not used at all for a certain period of time, it is possible to schedule it to be turned off during that period.

fig.26

fig.27

7. On-Demand Systems

(Real time End-to-End service linkage)

As a result, the load on administrators reduced operational errors can be prevented.

Storage system that incorporate the five key areas explained so far; "Business continuation", "Security and compliance", "Lifecycle management", "Information sharing and retrieval", and "Green products" help in the construction of new systems capable of providing on-demand services. Customers can then use storage capacity and I/O performance that are packaged as services as required and whenever necessary. The benefits of storage device management are efficient setup and operation. Events such as "unexpected shortages in storage capacity" and " occurrence of I/O bottlenecks" can be flexibly dealt with by the securing of sufficient capacity and performance.

fig.28

7-1 Virtual disks and virtual storage pools

Virtual disks and virtual storage pools can allocate storage capacity flexibly according to business load.

Benefits of virtual disks

From virtual storage pools to virtual resource pools

It is generally possible to create necessary disk capacity by virtualizing disks regardless of storage device capacity. Also, virtual disks can be more easily expanded. In addition, disk capacity can also be flexibly allocated to servers through unified management (pool operation) of disk capacity in the storage device. Fujitsu's virtualization switch ETERNUS VS900, which supports multiple platforms, provides storage pool capability. An advanced version of this idea is a virtualization system which includes storage. Virtual resource pools are constructed by virtualizing the network, servers, and storage. System administrators can allocate virtual disks in a flexible and on-demand manner according to business load, without concern for physical devices.

Storage virtualization technology frees datacenters from the following operation tasks.:

fig.29 - Logical volume creation in the storage system - Server address (WWN) registration in the storage system

- Logical volume setup in the storage system (Host affinity)

- Zone settings for fibre channel switches

18


7-2 Operation using virtual systems

The following three operation types enable virtual systems:

Automated virtual system creation Virtualization technology allows prompt creation of a virtual system (virtual sever + virtual storage). Virtual server management selects a virtual server from the virtual server pool based on requirements and allocates it to the virtual system. In the same manner, virtual storage management chooses virtual storage, matched to needs, from the virtual storage pool and allocates it to the virtual system. Then the OS image that matches requirements is high speed copied from the OS master. In this way, a system best suited to the services required is easily created.

fig.30

Demand forecasting of required resources

Resource and performance monitoring is very important for operations based on virtual systems. Resource and performance management functions are provided for virtual system integration management of virtual systems that integrate virtual servers and storage. The usage status of the

entire resources (including CPU, memory, and data extent) in the current virtual system can be checked and future demand on those resources can be predicted using the resource management functions of the virtual system.

Migration between devices without stopping business operation

Data can be migrated to a newly installed device without business interruption by registering new storage in a storage pool and specifying the target old virtual volume. As a result administrators are freed from the many troublesome tasks associated with migration.

fig.31

7-3 Grid storage system (Future of storage virtualization)

It is expected that in the future, when the storage pool concept is well-established and physical network infrastructure is completely Ethernet, all I/O protocols used for current storage will be handled by one network device. The storage structure of business data will use optimal protocols and the same optimal protocols will be used as the data access method. In this way Fujitsu will provide storage that is best suited for business operation without concerns about storage space

8. Core Technology (Commitment to data availability and reliability improvement)

Component redundancy/active replacement

Fujitsu is committed to data availability and reliability and that realization has been a corporate policy since inauguration of business. It is such a part of our culture it could be said to be incorporated into the DNA of each of our employees.

Reliability is guaranteed by making every component fully redundant. Those components are also hot-swappable and hot-expandable. For example, when a disk drives fails, the background process automatically rebuild data onto a hot spare disk. This enables failed disk drives to be hot-swapped without losing data redundancy.

With storage, we seek highly reliable systems that use carefully-selected, highly reliable components with integrated system control that improves availability. Component redundancy/active replacement, RAID technology, hot swapping/rebuilding, and data mirroring all ensure redundant configuration. To guarantee component level reliability evaluation of each circuit element and accelerated evaluation of a component's service life based on operational stress testing are performed.

Accelerated evaluation of a component's service by operational stress testing

Activation is checked after components are left for 24 hours in environments of -35°C, 100°C and 92% humidity.

Evaluation of all circuit elements through simulated failure

Fujitsu verifies that recovery can be performed without fail and business can continue without interruption in the event of failure. This is the way we guarantee integrity and security of information distribution and control paths. As stated above Fujitsu is takes a unique approach to providing high quality and high reliability.
