Agenda

Next Steps ?

Traditional x86 Architecture

• Single OS image per machine

• Software and hardware tightly coupled

• Multiple applications often conflict

• Underutilized resources

Old Standard Server Approach

Previous Application Landscape

Data Base

In traditional application deployments, there can be significant server sprawl primarily due to the need to provision separate systems for:

• development (DEV),

• quality assurance/test (QAS)

• production (PRD) environments.

Data Base

• What about hundreds of customers

(and systems) ?

• Complexity of large implementation ?

Virtualized (Shared) Architecture

• Virtualization ESX Server

• Runs directly on hardware

• Advanced Resource Management (cpu, memory, disk, network)

• High performance and high throughput

• SMP Capability

• Clustering across physical servers

• Multi-OS supported

Actual Virtualization Approach (1/2)

• Reduce costs by consolidating services onto the fewest number of

physical machines as Infrastructure needs

•Maintenance, Leases

•Networking

•Floor space, Cooling, Power

•Disaster Recovery

• Provide failover and high availability

• Isolate environment but shared hardware

• Make better use of capacity

• Remove/reduce the limited flexibility in shared environments

• Provide more opportunity for server maintenance during normal working hours

• Allow heterogeneous environments (OS) on the same hardware

Actual Virtualization Approach (2/2)

Virtualization Features

• DRS Business-customer Impact ?

• HA Business-customer Impact ?

• VMOTION Business-customer Impact ?

• Align IT resources with business priorities,

• Operational simplicity; dramatically increase system administrator productivity,

• Add hardware dynamically to avoid over-provisioning to peak load

• Cost effective high availability for all applications,

• No need for dedicated stand-by hardware,

• None of the cost and complexity of clustering

• Zero downtime,

• Complete transaction integrity,

• Continuous service availability,

Hardware maintenance without scheduling

Virtualization

Additional Business Advantages …

• Rapid Provisioning & Change Management

• Each new major Application release requires 20-25% more resources

• Move old systems to new hardware easily

• Free-up space from old hardware,

• Benefit from compute power immediately

• Simple maintenance of old application system for compliance

• Realize immediate ROI

• Decrease data centre costs: hardware, labor, floor space, energy,

cooling

• Easier to manage less resource

• Agility & Adaptive

• Can align/adjust/adapt faster „business/application‟ to the market

changes/business requirements.

Virtualization New Challenges …

• Security

• The virtual layer will become a potential target for attack for the virtual

services (multiple virtual machine) being hosted.

• Network access (dedicated NIC, VLAN, …)

• Management

• Costs estimation, ROI, …

• Additional tools

• Storage

• To be optimum, a SAN/NAS is “required”.

• VMWARE features (Vmotion, HA, DRS…)

• Backup/restore/DR

• Space efficiency

Virtualization Some Figures

• 20 ESX servers in DCA, 20 ESX servers in DCB

• ESX servers used for ERP (customers)

• ESX servers used for DMZ

• Total Virtual Machines : +/- 450

• ERP DCA = xx

• DMZ DCA = xx

• ERP DCB = xx

• DMZ DCB = xx

RAID-DP

Storage Efficiency

Business-customer Impact ?

• Higher Data Protection

• Provides Double Disk Failure Protection,

• Dramatic improvement in data protection at no additional cost,

• Optimized for Performance while providing maximum protection

• Reduces RAID group Rebuild Time while reducing RISK limiting exposure

to same RAID group second disk failure or non-recoverable media error.

• Higher capacity and lower cost.

• Compared to competitive offerings requiring RAID1/0 to provide similar

double disk failure protection double disk drive costs

Storage Features:

Disk Failure RAID-DP

Storage Features: Pool of Disk/Space Aggregate

• Can be grown by adding more disks,

• Can have multiple per system performance &

granularity,

• Separates physical allocation from space visible to users,

• Manage the storage pool as a resource independent of the

volumes.

Storage Features:

Flexible Space Allocation FlexVol

• Improve data management capabilities

• Volumes can be sized dynamically

• Can grow or shrink no disruptively

• Can be as small as a few MBs and as large as TBs (16)

• No pre-allocation of blocks to a specific volume

• Free space flows among all FlexVols in an aggregate;

space reallocation without any overhead

• Benefits of Thin Provisioning

• Increasing I/O Performance (spindle)

Storage Features: Management Software 4 Years ago ...

• Test all SnapManagers during POC

• Nice tools if you want a graphical interface

• Works fine to make a Snapshot

• Poor integration with SnapMirror

• NO integration with SnapVault

• Created custom scripts for Oracle and SAP

• Created custom scripts for Vmware based on VIBE script, SnapCreator

• Now testing Snapmanagers again

Storage Features: Protocol NFS ???

Strengths Delivers best IO scaling for

shared datastores

Simplest storage management

Transparent storage virtualization

Inexpensive storage networking

Eliminates storage dead spots

No restriction with vSphere feature set

Be Aware: Not as common outside of NetApp & EMC installs

Our largest customers have adopted NFS for simplicity and scalability

Agenda

Next Steps ?

NFS Storage Implementation New challenges ...

• Security

• Share data of multiple customers on same box

• Audit ?

• Limit Access to data ? (Multistore, NFS, Kerberos, VLAN,…)

• Data protection

• Encryption ? (database level Oracle , storage level

Decru, …)

• Type of data: Online data, offline data ?

• Offline backup

• Mirror Snapvault (disk backup ) between data centre

• Customer acceptance (cultural)

Storage Features: Instant Image/Copy FlexClone

• Enables multiple, instant data set clones with no storage overhead:

• Immediate,

• No performance implications,

• Dramatic improvement for application test and development

environments

• Large space savings for similar volumes,

• Use database clones to test migrations, apply bug fixes, upgrades,

and patches

Working with passionate people is

an advantage because:

• What would you do for your

passion? A LOT ...

• What is behind the technology?
