IBM i Client Partition Technologies IBM i hosting IBM i virtual client LPARs i 6.1 host LPAR provides disk, optical to i 6.1 client LPAR Client LPAR is assigned no physical hardware in HMC Host LPAR virtualizes integrated or SAN disk to client Rapid deployment of test/dev/q&a LPARs Requires hardware hosting IBM i virtual client LPARs Virtual I/O Server () provides disk, optical to i 6.1 client LPAR Client LPAR is assigned no physical hardware in HMC virtualizes SAN disk to client Leverage investment in DS4000 for IBM i Requires hardware HMC managed server can host multiples of all types i 6.1 Virtual Client LPARs FC 5294 EXP24 DS8000 NWSSTGs OPTxx IVE IBM i Host DDxx Virtual SCSI Virtual LAN IBM i Client OPTxx CMNxx DDxx DASD Hardware assigned to host LPAR in HMC DASD can be integrated or SAN DASD virtualized as NWSSTG objects Optical drive in host LPAR virtualized directly (OPTxx) Networking Network adapter (such as IVE) and Virtual Ethernet adapter in host LPAR Virtual Ethernet adapter in client LPAR 2
Client LPAR Configuration HMC Virtual SCSI client adapter DASD and optical are accessible through the same VSCSI client adapter By using multiple adapters, a virtual client LPAR can use DASD from multiple hosts Client LPAR Configuration Load Source Both B- and D-mode IPL devices are set to virtual SCSI client adapters When installing virtual client LPAR, D-mode IPL is performed from drive in host LPAR LIC and OS are installed on NWSSTG (Network server storage space) objects 3

and i 6.1 Client Configuration HMC configuration is the same as with IBM i host: Virtual SCSI server adapter(s) in LPAR Virtual SCSI client adapter(s) in virtual client LPAR is assigned 1 or more Fibre Channel adapters SAN configuration: LUNs are standard System p/aix 512B LUNs LUNs do not have to be specific sizes supported by IBM i (71, 141, 382 GB, etc.) Virtualization of LUNs, optical, Ethernet is configured using command line* via Telnet or PuTTY Virtual client LPAR installation is the same as with IBM i host * section in IBM System Information Center: http://publib.boulder.ibm.com/infocenter/eserver/v1r3s/index.jsp?topic=/iphb1/iphb1kickoff.htm i 6.1 Function New i 6.1 Function 5
Virtual Storage Space Snapshots Save a NWSSTG while it is active. longer have to VARYOFF the server IBM i does Checkpoint and keeps track of changed data during save Checkpoint thrown away when done. Supported via IBM i SAV command and BRMS SAVACT - *YES SAVACTOPT - *NWSSTG Virtual Storage Space Snapshots continued. Windows Server iscsi only (not IXS or IXA) communicates with ADMIN Service ( freeze, prepare for backup (Volume Shadow Copy Service API), thaw ) intended for applications that are VSS aware Power Linux requires Power5, Power5+ or Power6 hardware communicates with ADMIN Service ( freeze, SYNC, thaw ) x86 Linux iscsi only (not IXS or IXA) communicates with ADMIN Service ( freeze, SYNC, thaw ) VMware iscsi only (not IXS or IXA) IBM i & AIX requires Power5, Power5+ or Power6 6
