  • Common Europe Conference – Vienna | June 2012 What is iSCSI? iSCSI - internet SCSI (Small Computer System Interface), SCSI commands sent across a Initiator network in TCP/IP packets. It was developed as a storage Target networking standard for linking data storage facilities Initiator - system making the iSCSI requests for data Target - system receiving the iSCSI requests for data Power System © 2012 IBM Corporation
  • Common Europe Conference – Vienna | June 2012IBM i Integration with BladeCenter and System x iSCSI connection between IBM i and BladeCenter System x using iSCSI HBAs (Host Bus Adapters) or standard ethernet ports. Standard ethernet cables and switches (gigabit). IBM i 6.1 enables iSCSI Software Initiators IBM i 7.1 enables iSCSI Software Targets IBM i IBM i6 © 2012 IBM Corporation
  • Common Europe Conference – Vienna | June 2012Software Target SupportIn an IBM i 6.1 (and previous releases) Integrated Server Environment the customer is limited to an environment containing physical iSCSI Target HBAs with 1GB connectivity.In IBM i 7.1, we have implemented the new software target solution you can use dedicated 1GB or 10GB Ethernet ports for iSCSI connectivity. IBM i © 2012 IBM Corporation
  • Common Europe Conference – Vienna | June 2012Software Target Details Target Side Initiator Side • No Target iSCSI HBA required • No Initiator iSCSI HBA required* • Use dedicated Ethernet adapters/ports • Use dedicated Ethernet adapters/ports • can be either 1 Gb or 10 Gb • can be either 1 Gb or 10 Gb • NWSH points to virtual device • Can mix hardware and software initiators • Can mix hardware and software Targets Dedicated 1Gb or 10Gb connections Advantages • Enable support in POWER7 (no iSCSI HBA support) • Can get to 10 Gb infrastructure • Reduce cost of solution • No specialized hardware required * Supported on certain models, see supported hardware list © 2012 IBM Corporation
  • Common Europe Conference – Vienna | June 2012Software Initiator Configuration Considerations Microsoft iSCSI Initiator Service is required for every server that requires more than one session – Initiator code must be downloaded from Microsoft for Windows Server 2003 Ensure the latest BIOS/Firmware is installed for both the server and network adapters (NIC) Enable software initiator as the boot device in the BIOS/UEFI setup menu Software Initiator must be used with VMware ESXi5 servers © 2012 IBM Corporation
  • Common Europe Conference – Vienna | June 2012 VMware on BladeCenter and System x Integrated with IBM i VMware ESX is a leading IBM i integration with BladeCenter virtualization solution for x86 and System x via iSCSI supports servers VMware ESX – Virtualization supports multiple – IBM i provides virtual storage support Windows, Linux, and Netware for VMware ESX servers environments on a single server – Extends the value of advanced IBM i – Enables the reduction of the number of storage management physical servers IBM System i Power Systemhttp://www-03.ibm.com/systems/i/bladecenter/ © 2012 IBM Corporation

  • Common Europe Conference – Vienna | June 2012IBM i 7.1 Enhancements – VMware Support ChangesSupport for VMware vSphere in IBM i 7.1• VMware ESXi server management The IBM i Integrated Server Support software does not run directly on the VMware ESX server. Instead, an iSCSI attached integrated Windows server serves as a management server for the VMware ESX server. An integrated Windows server can serve as the management server for any number of integrated VMware ESX servers within the same IBM i logical partition. At least one integrated Windows server is required in each IBM i logical partition that hosts integrated VMware ESX servers.

This allows a concurrent save of ESX data without requiring the ESX server to be shut down or applications ended. • See the IBM i iSCSI Solution Guide, section 7.8.4 for additional information. • The following IBM i group PTFs are used to deliver this enhancement: • IBM I 7.1 Group PTF: SF99369 Level 6 (June 2011) 24 © Copyright IBM Corporation 2011 © 2012 IBM Corporation

  • Common Europe Conference – Vienna | June 2012PTFs Before installing an integrated server, load all of the following required PTFs: Note: Use the IBM i WRKPTFGRP command to verify that you have the latest level of the group PTF installed. Action required: The group PTF for your IBM i release contains a service pack PTF for the IBM i Integrated Server Support code that runs on the integrated Windows or VMware ESX server. After installing the group PTF, you need to install the service pack from IBM i to each Windows or VMware ESX Server. See the Installing IBM i integration service packs section of the IBM i iSCSI Solution Guide for service pack installation instructions.

  • Common Europe Conference – Vienna | June 2012Service Processor Manager (SPM) In IBM i 7.1 Service Processor Manager (SPM) is a build in function of IBM i. The SPM functionality has been PTF’ed into IBM i 6.1 Before IBM i 7.1 – In previous releases the customer had the option to either use Service Processor Manager or IBM Director (5722-DR1) for integrated server management connections and power control. Enhancement – IBM Director (5722-DR1) is no longer used for server management connections or power control. This reduces the software requirement for the Integrated Server solution by no longer requiring 5722-DR1 to be installed on the IBM i. NOTE: The newer System x server models require SPM because they use a newer service processor called an imbedded management module (IMM).41 © 2012 IBM Corporation
