Logical partitioningLogical partitioning is the ability use a server as if it were two or more independent servers.
You can use logical partitioning to consolidate servers, share system resources, create mixedenvironments, and run integrated clusters.
Important logical partitioning concepts include:
Sharing resourcesAlthough each logical partition acts as an independent server, the logical partitions on a servercan share some kinds of resources with each other.
Managed systemsA managed system is a single physical server plus the resources that are connected to thephysical server.
Manufacturing default configurationThe manufacturing default configuration is the initial single partition setup of the managedsystem as received from your service provider.
Physical and virtual hardware resourcesWhen you create logical partitions on a managed system, you can assign the physical resourceson the managed system directly to logical partitions. You can also share hardware resourcesamong logical partitions by virtualizing those hardware resources.
For more information about logical partitions, see the topic corresponding to your system in the SystemsHardware Information Center.

Micro-PartitioningMicro-Partitioning distributes the processing capacity of one or more physical processors among one ormore logical partitions. Micro-Partitioning significantly increases overall utilization of processor resourceswithin a system.
You can use Micro-Partitioning to significantly increase utilization of processor resources in your system.
Important Micro-Partitioning concepts include:
Processing units of capacityYou can configure processing capacity in processor increments of 0.01. You must assign a
Getting started with virtualization using IBM PowerVM 5
minimum processing capacity to a micro-partition. The minimum processing capacity dependsupon your hardware and firmware. The following list describes the processing capacity fordifferent Power Systems servers:
POWER5 and POWER60.1 processors
POWER7®
See Shared processors (http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/p7hat/iphatsharedproc.htm)
PowerLinuxSee Shared processors (http://pic.dhe.ibm.com/infocenter/powersys/v3r1m5/index.jsp?topic=/p7hatl/iphatsharedproc.htm)
For more information about processing capacity, see Use increased Micro-Partitioning limits on aPower system running Linux (https://www.ibm.com/developerworks/mydeveloperworks/wikis/home?lang=en#/wiki/W51a7ffcf4dfd_4b40_9d82_446ebc23c550/page/Use%20increased%20Micro-Partitioning%20limits%20on%20a%20Power%20system%20running%20Linux).
Capped and uncapped modeCapped and uncapped processing modes determine whether processing capacity can exceedentitled capacity when more resources are available in the shared-processor pool.
Virtual processorsA virtual processor is a representation of a physical processor that is presented to the operatingsystem, which is running in a micro-partition.
Virtual processor foldingVirtual processor folding puts idle virtual processors into a hibernation state to conserve physicalprocessor resources.
Dedicated processorsDedicated processors are whole processors that are assigned to dedicated-processor logicalpartitions (LPARs). The minimum processor allocation for an LPAR is one whole processor; themaximum is the total number of installed processors in the server.
Shared-processor poolsShared-processor pools aggregate processor resources. Shared-processor pools have differentcharacteristics in POWER5 servers than in POWER6 servers and later. POWER5 servers supportone shared-processor pool that is called the physical shared-processor pool. POWER6 servers andlater support several shared-processor pools that are called multiple shared-processor pools.
Shared dedicated capacityOn POWER6 servers and later, you can configure dedicated-processor partitions as donatingpartitions, which donate unused cycles to the shared-processor pool.
For more information about Micro-Partitioning, see the topic corresponding to your system in theSystems Hardware Information Center.

Active Memory sharingWith Active Memory sharing, multiple logical partitions can share a common pool of physical memory.Physical memory can be assigned to multiple logical partitions in either a dedicated or shared mode.
You can use Active Memory sharing to create more logical partitions with the same amount of memory,or to decrease the overall system memory requirement.
Active Memory sharing requires POWER6 and later processor technology.
Important Active Memory sharing concepts include:
Dedicated and shared-memoryYou can assign traditional dedicated memory to single logical partitions, and create a memorypool that can be shared among logical partitions.
Shared-memory poolThe shared-memory pool is a collection of physical memory blocks that are managed as a wholeby the hypervisor. The memory in the pool is reserved upon creation, and no longer available forallocation to other dedicated memory partitions. The shared-memory pool is directly managed bythe hypervisor for exclusive use by shared-memory partitions.
Paging Virtual I/O ServerYou can configure the Virtual I/O Server to page memory dedicated to the shared-memory poolto a paging device. The paged memory is restored when the data is accessed again.
Shared-memory partitionsA shared-memory partition is an LPAR that uses memory from the shared-memory pool. Ashared-memory partition must use:v Shared processors.v Virtual I/O.v Red Hat Enterprise Linux 6 or SUSE Linux Enterprise Server 11, kernel 2.6.27.25-0.1-ppc64 or
later.
Logical and physical memoryYou can configure the amount of logical memory available to a shared-memory partition. You canprioritize the probability that more physical memory is assigned to the partition.
Memory classificationLinux tags each logical memory page to indicate its importance. The hypervisor uses thisinformation to prioritize the pages that have a lower effect on shared-memory partitionperformance.
For more information about Active Memory sharing, see the Active Memory Sharing topic for your systemin the Systems Hardware Information Center.

Getting started with virtualization using IBM PowerVM 7
Active Memory deduplicationActive Memory deduplication reduces shared-memory overcommitment by eliminating memory pages inthe same LPAR or across LPARs on the same server.
You can use Active Memory deduplication to minimize the existence of identical memory chunks in mainmemory space.
Active Memory deduplication requires POWER7 and later processor technology. Active Memorydeduplication depends upon “Active Memory sharing” on page 7.
Important Active Memory deduplication concepts include:
Active Memory deduplicationActive Memory deduplication reduces identical pages that are stored in separate memory chunksinto only one page. The reduction occurs even when the identical pages are in differentshared-memory partitions.
Hypervisor logical memory mapThe hypervisor logical memory map is a table within PowerVM that maps LPAR memory pagesand physical pages.
Copy-on writeCopy-on-write is a PowerVM mechanism that tracks all deduplicated memory pages. When ashared-memory partition changes a deduplicated page, the hypervisor makes a copy of thatdeduplicated physical page. The hypervisor then gives the new copy back to the write-requestingshared-memory partition. Other shared-memory partitions continue to reference the deduplicatedpage.
Deduplication tableThe hypervisor scans and creates signatures for all physical memory pages in a deduplicationtable. When it finds pages with the same signature, the hypervisor compares the pages todetermine whether they are identical and can be deduplicated.
Operating system collaborationActive Memory Deduplication works independently of the operating system. However, newerversions of the supported operating systems can collaborate with PowerVM by indicating thepages that are likely candidates for being deduplicated. Likely candidates are frequently textpages, which contain code instructions. The indication is a refinement of the memoryclassification that is performed by “Active Memory sharing” on page 7.
Memory oversubscriptionActive Memory deduplication helps avoid physical memory overcommitment, which minimizesthe amount of operating system and Active Memory sharing paging that occurs.
For more information about Active Memory deduplication, see the Power Systems MemoryDeduplication (http://www.redbooks.ibm.com/abstracts/redp4827.html) IBM Redbooks® publication.
Virtual I/O ServerThe Virtual I/O Server shares physical resources between supported Linux partitions. The Virtual I/OServer also provides features such as Active Memory sharing, Suspend/Resume, and live partitionmobility.
Use the Virtual I/O Server to achieve more efficient utilization and flexibility of physical storage andnetwork devices.
Important Virtual I/O Server concepts include:
8 Linux: Getting started with virtualization for PowerLinux
Virtual storageThe Virtual I/O Server allows virtualization of physical storage resources. Virtual storage devicesare accessed by client partitions through virtual SCSI.
Virtual networkingThe Virtual I/O Server allows shared access to external networks through the Shared EthernetAdapter (SEA).
Additional Virtual I/O Server concepts apply to POWER6 and later processor technology:
Virtual storageWith N_Port ID Virtualization (NPIV), you can configure the managed system so that multiplelogical partitions can access independent physical storage through the same physical FibreChannel adapter.
Virtual networkingThe Virtual I/O Server allows shared access to external networks through Internet Protocolversion 6 (IPv6), Link Aggregation (or EtherChannel), Shared Ethernet Adapter failover, andVLAN.
Shared-memoryShared-memory is physical memory that is assigned to a shared-memory pool and shared amongmultiple logical partitions.
Paging VIOS partitionA Virtual I/O Server logical partition that is assigned to the shared-memory pool provides accessto the paging space devices for the logical partitions that are assigned to the shared-memorypool.
For more information about the Virtual I/O Server, see the topic corresponding to your system in theSystems Hardware Information Center.

Live partition mobilityWith PowerVM live partition mobility, you can move a running logical partition from one system toanother. Live partition mobility includes active partition mobility and inactive partition mobility.
With active partition mobility, you can move Linux logical partitions that are running, including theoperating system and applications, from one system to another. The logical partition and the applicationsthat are running on it do not have to be shut down.
With inactive partition mobility, you can move a powered off Linux logical partition from one system toanother.

System virtualization managementDepending upon your system, you can manage system virtualization with the Hardware ManagementConsole (HMC), the Integrated Virtualization Manager (IVM), or the IBM Flex System Manager™ (FSM).
Hardware Management ConsoleThe Hardware Management Console (HMC) is a system management appliance for Power Systemsservers.
The Hardware Management Console provides a graphical user interface and a command-line interface forsystem virtualization management. You can use the Hardware Management Console to create andmanage logical partitions, configure virtual resources for logical partitions, and manage the sharedmemory pool.

Differences between Power Systems and x86 environmentsLearn about the differences in configuration and terminology between Power Systems environments andx86 environments.
Configuration differences
In x86 environments, it is common to set up and configure hardware RAID to protect the system fromdisk failures. Typically, configuring hardware RAID is one of the first steps in setting up x86 servers.
In Power Systems environments, it is common to protect the system against disk failures by mirroring thedisks. You mirror the disks by running a command in the Integrated Virtualization Manager (IVM) afterIVM is installed. If you want to set up RAID instead, you can use the IBM Installation Toolkit forPowerLinux or the IBM Standalone Diagnostics CD. However, setting up RAID might require that youreinstall IVM if IVM is already installed.
Terminology differences
IVM uses Power Systems terminology, which is sometimes different from x86 terminology. The followingtable lists terms that are used in IVM environments, maps them to similar x86 terms, and provides adefinition for the terms.
IVM term or concept x86 term or concept Definition
managed system server or system A physical server that containsphysical processors, memory, andI/O resources that is often virtualizedinto virtual servers, which are alsoknown as client logical partitions. Inthis case, the managed system is thePowerLinux server.

Before you start, ensure that you are the prime administrator (padmin).
Step 1: Connecting to the web-based interfaceTo connect to the web-based interface for the Integrated Virtualization Manager (IVM), you must verifythe network connection and configure the TCP/IP connection.
To connect to the web-based interface, complete the following steps:1. From the serial console, log in to the management partition with the padmin user ID.2. When prompted, change the login password to a secure password that adheres to your local
password-security guidelines.3. Accept the license agreement with the license command.4. Ensure that there is a network connection configured between the management partition and at least
one of the physical Ethernet adapters on the managed system. With this connection, you can accessthe IVM interface from a computer that is connected to the physical Ethernet adapter. You cannot usethe HMC1 and HMC2 ports to connect to the management partition.
5. Configure the TCP/IP connection for the management partition with the mktcpip command. Forexample:mktcpip -hostname fred -inetaddr 9.5.4.40 -interface en0 -start -netmask 255.255.255.128 \-gateway 9.5.4.1 -nsrvaddr 9.10.244.200 -nsrvdomain austin.century.com
6. Open a web browser window and connect with the HTTP or HTTPS protocol to the IP address thatyou assigned to IVM in Step 5. For example, enter https://9.5.4.40 in your web browser. TheWelcome window is shown.
7. Enter the default user ID of padmin, and enter the password that you defined in Step 2. The IVMinterface is shown.
8. Verify that IVM has the latest fix packs and updates:a. In the navigation area, select Updates under Service Management. The Updates page is shown.b. View the current code level of IVM.c. Go to the website provided on the page to find the latest available updates and directions for how
to apply the updates.

Step 2: Mirroring the management partitionTo prevent potential downtime and data loss, add a second disk to the rootvg storage pool and mirrorthe two disks.
When you install Integrated Virtualization Manager (IVM), it automatically creates a storage pool calledrootvg and assigns one physical volume to rootvg. IVM and any data that IVM uses initially is stored onthe management partition (partition ID 1) on that physical volume. If that disk fails, you cannot manageyour client partitions and suffer downtime and the loss of data. To prevent this kind of interruption toyour business, you need to add a second disk to the rootvg storage pool and mirror the two disks.
To mirror the management partition, complete the following steps:1. Add a new physical volume to the rootvg storage pool:
a. In the navigation area, select View/Modify Virtual Storage under Virtual Storage Management.The View/Modify Virtual Storage page is displayed.
b. Select the Storage Pools tab.c. From the Tasks menu, click Create Storage Pool. The Create Storage Pool page is displayed.d. Enter a unique name for the new storage pool.e. Select Logical volume based as the storage pool type.f. Select a physical volume for the storage pool and click OK.
2. Mirror the new volume:a. In the navigation area, select View/Modify Partitions under Partition Management. The
View/Modify Partitions page is displayed.b. Select the management partition.c. From the Tasks menu, select Open terminal window. A virtual terminal window is shown.
Note: Because the applet has a digital signature, your browser might display a security warningand ask you to verify that you want to run the applet.
d. Enter the password for your login ID from the current IVM session. A terminal session starts forthe management partition.
e. At the command prompt, run the extendvg command as follows:extendvg rootvg Physicalvolume
where Physicalvolume is the name of the volume that you just added to rootvg.f. At the command prompt, run the mirriorios command as follows:
mirrorios Physicalvolume
where Physicalvolume is the name of the volume that you just added to rootvg.
Restriction: The mirrorios command mirrors only the rootvg storage pool. It does not mirrorother volume groups or any virtual disks that are created on rootvg after it is initially mirrored.
g. Verify that the mirrored physical volume is included in the bootlist by running the followingcommand:bootlist -mode normal -ls
3. If the mirrored volume is not included in the bootlist, add it using the following command:bootlist -mode normal hdisk0 hdisk1
14 Linux: Getting started with virtualization for PowerLinux
where hdisk0 and hdisk1 are the mirrored physical volumes.
Step 3: Configuring storage on the managed systemYou can configure storage on the managed system to meet the storage needs of the logical partitions thatyou create.
For a simple setup, consider configuring storage for one of the following scenarios:
Environments with local storageYou can create a storage pool in addition to the default rootvg storage pool for regular datastorage, and then assign the new storage pool as the default. When you create logical partitions,you can create virtual disks from the storage capacity of the storage pool, and assign the virtualdisks to the logical partitions. Virtual disks allow you to specify more precisely the amount ofstorage that you assign to logical partitions. You can assign storage to logical partitions withoutregard to the actual capacities of the physical volumes that make up the storage pool.
Table 1. Some benefits and drawbacks to using local storage
Benefits Drawbacks
v Using local storage can reduce the amount of disksthat are assigned to IVM because multiple clientlogical partitions can access the same physical disk.
v You can create additional logical volumes as neededand assign them quickly.
v Using local storage can cause some resourcecontention if the client logical partitions perform rapidI/O operations on the same physical disk.
v Environments with local storage do not support LivePartition Mobility.
Environments with a storage area network (SAN)You can assign physical volumes directly to the logical partitions. A physical volume is anindividual logical unit that is identified by a logical unit number (LUN). A physical volume canbe a hard disk or a logical device on a SAN. Configure storage with a SAN if you plan to useLive Partition Mobility.
Table 2. Some benefits and drawbacks to using SAN storage
Benefits Drawbacks
v Using a SAN provides the client logical partition withdirect access to a SAN physical volume.
v Environments with a SAN support Live PartitionMobility.
v Managing a large quantity of disks on IVM and theclient logical partitions to which they are mapped canbecome complex.
v If you need to boot IVM to the System ManagementServices (SMS) menu, IVM can take a long time toprobe all of the disks. IVM might also identify severaldisks as root volume groups (look for the IVM name).
Generally, the physical volumes and virtual disks that you assign to a logical partition display as physicaldisk devices in the operating system interface of the logical partition.Related information:
Live Partition Mobility
Configuring storage for environments with local storageTo create a storage pool for regular data storage, complete the following steps:1. In the navigation area, select View/Modify Virtual Storage.2. Select the Storage Pools tab.3. From the Tasks menu, click Create Storage Pool. The Create Storage Pool page is displayed.4. Enter a unique name for the new storage pool.5. Select Logical volume based as the storage pool type.
Getting started with virtualization using IBM PowerVM 15
6. Select Assign as default storage pool.7. Select one or more physical volumes for the storage pool and click OK.
Configuring storage environments with a SAN1. Obtain the world wide port name (WWPN) for each fibre channel adapter:
a. In the navigation area, select View/Modify Partitions under Partition Management. TheView/Modify Partitions page is displayed.
b. Select the management partition.c. From the Tasks menu, select Open terminal window. A virtual terminal window is shown.
Note: Because the applet has a digital signature, your browser might display a security warningand ask you to verify that you want to run the applet.
d. Enter the password for your login ID from the current IVM session. A terminal session starts forthe management partition.
e. At the command prompt, run the lsdev command as follows:lsdev -dev fcs*
The output shows all of the adapters of the fcs type.f. Run the following command for each adapter:
fcstat adaptername
where adaptername is the name of the adapter as identified in Step 1e. For example, fcstat fcs1.The output shows information about the adapter, including its world wide port name (WWPN).
g. Record the WWPN of each adapter.2. From the SAN tools, zone and assign storage to the WWPNs that you recorded in Step 1g.3. From the command prompt of the IVM virtual terminal, run the following command for each adapter
so that IVM recognizes the new LUNs that you assigned to the adapters:cfgdev -dev adaptername
where adaptername is the name of an adapter to which you assigned storage from the SAN. Forexample, cfgdev -dev fcs1.
Step 4: Configuring virtual Ethernet on the managed systemYou can configure virtual Ethernet on the managed system to meet the networking needs of the logicalpartitions that you create.
For a simple setup, consider configuring one of the following types of virtual Ethernet:
Host Ethernet Adapter (HEA) or Integrated Virtual Ethernet (IVE)An HEA is a unique Ethernet adapter that is built into the system. It provides the ability topartition a physical Ethernet port. An HEA can contain one or more physical ports and eachphysical port can be assigned to zero or more logical partitions.
Table 3. Some benefits and drawbacks to using HEA or IVE
Benefits Drawbacks
v The initial setup of an HEA is easier than the initialsetup of an SEA.
v HEA provides high performance.
v HEA does not support Live Partition Mobility.
v HEA supports a limited number of client logicalpartitions. HEA supports up to 32 logical ports. IVMuses at least one logical port, so HEA supports up to31 client logical partitions.
16 Linux: Getting started with virtualization for PowerLinux
Configuring an HEA does not require configuration of the IVM management partition. Youconfigure the HEA when you create the client logical partitions.
Shared Ethernet Adapter (SEA)An SEA is a virtual Ethernet bridge that connects the virtual Ethernet networks on your managedsystem to physical Local Area Networks (LANs). For greater security, do not set up the physicalEthernet adapter that you use to connect to the management partition as a virtual Ethernetbridge. With this configuration, you can isolate the management partition from all externalnetworks. (The management partition manages the virtual Ethernet networks on your managedsystem but does not participate in any virtual Ethernet networks.)
Table 4. Some benefits and drawbacks to using an SEA
Benefits Drawbacks
v An SEA supports an almost unlimited number ofclient logical partitions.
v An SEA provides fast communication between clientlogical partitions.
v An SEA supports Live Partition Mobility.
v The initial setup of an SEA is more complex than theinitial setup of an HEA.
v An SEA uses processor cycles in IVM for sendingpackets to the external LANs.
Configuring an SEA requires some configuration of the management partition as described in thefollowing procedure.
Related information:
