IBM i Direct Support for DS 5100 and DS 5300 Overview IBM Power Systems § IBM i supports direct attachment to DS 5100 and DS 5300 storage to enable simpler SAN planning and leverage midrange open storage § DS 5100 and DS 5300 benefits – Multiple RAID levels, including RAID 6 – Custom XOR processor for RAID calculations – Consolidated storage for IBM i, Unix, Linux, Windows applications – Can use FC or SATA drives § DS 5100 and DS 5300 currently supported § New support does not require Power. VM Virtual I/O Server (VIOS) – Power. VM may be required for shared processors, Active Memory Sharing § IBM i LPAR owns Fibre Channel adapter(s) – Two adapters required for redundancy § New IBM i host kit required on DS 5100 and DS 5300 – Feature code #7735 § IBM i supports Multi-path I/O with direct attachment to DS 5100 and DS 5300 – No additional software required on DS 5100 and DS 5300 – Round-robin algorithm used with Multi-path I/O in IBM i Power Hypervisor * All statements regarding IBM's future direction and intent are subject to change or withdrawal without notice, and represent goals and objectives only. 3 © 2009 IBM Corporation

IBM Power Systems Requirements, Best Practices and Limitations § Hardware requirements: – DS 5100 or DS 5300 – Power servers (Power blades not supported for direct attachment) – POWER 6 hardware – POWER 5(+) hardware not supported – Smart I/O adapter (IOPless adapter) #5735 (8 Gb dual-port PCI-E) #5774 (4 Gb dual-port PCI-E) #5749 (4 Gb dual-port PCI-X) § Software requirements: – IBM i 6. 1 with IBM 6. 1. 1 LIC refresh – IBM i 5. 4. 5 or earlier not supported – 7. 60. 26. 00 or later DS 5100 or DS 5300 controller firmware § Best Practices and limitations: – Maximum LUN size for IBM i is < 2 TB (volume size >= 2 TB will not work) – Mixing FC and SATA drives within enclosure is supported – FC drives recommended for production workloads – Maximum 64 LUNs per FC port (same as DS 8000 direct attach) – SSDs not supported at this time – Drive encryption in DS 5100/DS 5300 is supported – Boot from SAN requires active connection, IBM i will not IPL from passive connection – Maximum of 300 LUNs from a single DS 5100/DS 5300 per ASP add Adding more LUNs to same ASP requires multiple ASP adds – All LUNs must be protected (RAID 0 arrays for LUNs not supported) – Dynamic volume expansion on DS 5100 and DS 5300 is not supported – IBM i system-level disk mirroring not supported Disk protection configured on DS 5100 or DS 5300 Drives report in IBM i as protected (same as DS 8000 protected LUNs) 4 © 2009 IBM Corporation

Configuring DS 5100 and DS 5300 for IBM i Direct Attachment – Storage IBM Power Systems § Step 1: Perform sizing – Use Disk Magic for DDM/array sizing, use PCRM* for LUN sizing – Number of physical drives is still most important – Separate LUNs for production and development workloads on different RAID arrays – Array and LUN configuration for IBM i is different from that for AIX direct or for AIX through VIOS – Leverage service vouchers for assistance (see later in this presentation) § Step 2: Use DS 5100 and DS 5300 Redbook (SG-247676) to perform initial DS 5100 and DS 5300 setup § Step 3: Create RAID 5, RAID 6 or RAID 10 array § Step 4: Create 512 B LUNs based on Disk Magic sizing § Step 5: Create new host, type IBM i § Step 6: Map LUNs to new host § Make sure there are no hosts in default host group on DS 5100/DS 5300 DS Storage Manager – Storage partitioning recommended – IBM i will see LUNs attached to any host in the default host group in addition to its own hosts without storage partitioning * http: //www. ibm. com/systems/i/advantages/perfmgmt/resource. html 5 © 2009 IBM Corporation

Configuring IBM Power Systems DS 5100 and DS 5300 for IBM i Direct Attachment – Power System § Create IBM i LPAR, assign supported FC adapter(s), OR § Assign supported FC adapters to existing IBM i LPAR § Perform zoning – Zone each port on the FC adapter to connect to controller A or B – Maximizes redundancy and performance § Connect FC adapters to SAN fabric – See note on default host group on DS 5100/DS 5300 before performing this step 6 © 2009 IBM Corporation

Comparison with DS 5100 and DS 5300 Attachment to IBM i through VIOS IBM Power Systems § Performance: – Performance is expected to be similar in both environments – Direct attachment will not provide better performance – VIOS does not add significant overhead § Skills: – DS 5100 and DS 5300 and IBM i skills required – VIOS skills not required § Copy Services and replication: – DS 5100 and DS 5300 Flash Copy, Metro Mirror and Global Mirror supported for IBM i attachment through VIOS Full-system only IASPs not supported – IBM is investigating supporting Copy Services with direct attachment – Power. HA for i Geographic Mirroring is supported in both environments 7 © 2009 IBM Corporation
