IBM i Direct Support for DS5100 and DS5300 Overview
IBM i supports direct attachment to DS5100 and DS5300 storage to enable simpler SAN planning and leverage midrange open storage
DS5100 and DS5300 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
DS5100 and DS5300 currently supported
New support does not require PowerVM Virtual I/O Server (VIOS)– PowerVM 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 DS5100 and DS5300– Feature code #7735
IBM i supports Multi-path I/O with direct attachment to DS5100 and DS5300– No additional software required on DS5100 and DS5300– Round-robin algorithm used with Multi-path I/O in IBM i
Power Hypervisor

Requirements, Best Practices and Limitations Hardware requirements:
– DS5100 or DS5300– Power servers (Power blades not supported for direct attachment)– POWER6 hardware– POWER5(+) hardware not supported– Smart I/O adapter (IOPless adapter)
#5735 (8Gb dual-port PCI-E)#5774 (4Gb dual-port PCI-E)#5749 (4Gb 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 DS5100 or DS5300 controller firmware
Best Practices and limitations:– Maximum LUN size for IBM i is < 2TB (volume size >= 2TB 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 DS8000 direct attach)– SSDs not supported at this time– Drive encryption in DS5100/DS5300 is supported– Boot from SAN requires active connection, IBM i will not IPL from passive connection– Maximum of 300 LUNs from a single DS5100/DS5300 per ASP add
Adding more LUNs to same ASP requires multiple ASP adds– All LUNs must be protected (RAID0 arrays for LUNs not supported)– Dynamic volume expansion on DS5100 and DS5300 is not supported– IBM i system-level disk mirroring not supported
Disk protection configured on DS5100 or DS5300 Drives report in IBM i as protected (same as DS8000 protected LUNs)

Configuring DS5100 and DS5300 for IBM i Direct Attachment – Storage
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 DS5100 and DS5300 Redbook (SG-247676) to perform initial DS5100 and DS5300 setup
Step 3: Create RAID5, RAID6 or RAID10 array
Step 4: Create 512B 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 DS5100/DS5300– 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

Configuring DS5100 and DS5300 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 DS5100/DS5300 before performing this step

Comparison with DS5100 and DS5300 Attachment to IBM i through VIOS
Performance:– Performance is expected to be similar in both environments– Direct attachment will not provide better performance– VIOS does not add significant overhead
Skills:– DS5100 and DS5300 and IBM i skills required– VIOS skills not required
Copy Services and replication:– DS5100 and DS5300 Flash Copy, Metro Mirror and Global Mirror supported for IBM i
attachment through VIOSFull-system only
IASPs not supported
– IBM is investigating supporting Copy Services with direct attachment– PowerHA for i Geographic Mirroring is supported in both environments

NPIV Benefits for IBM i
Sharing dual-port 8Gb FC adapters among multiple partitions– One port from 2 separate adapters can be shared to same client partition, allowing for
adapter redundancy
Support for FC tape libraries in VIOS environment– Tape library recognized with device-specific machine-type and model (MTM) in IBM i and
all library functions supported
Support for DS8000 storage– Volumes recognized with device-specific MTM and as protected or unprotected
Support for DS8000 Copy Services with PowerHA in a VIOS environment– Similar to natively attached DS8000 today

storage LUNs– Improves availability of virtualized environment– Can assign two paging VIOS partitions to a shared memory pool to provide
redundant access to the paging devices.– Available on Power servers only, not on Power blades

IBM i Support for XIV
IBM i supports the XIV Storage System with PowerVM VIOS to leverage the innovative subsystem’s ease of management and performance
XIV benefits– Massive parallelism (all disk units used at all times)– Easy upgradeability– Simplified configuration– Unlimited snapshots with little effect on performance
VIOS can virtualize XIV storage to IBM i, AIX, Linux – PowerVM VIOS configurations with IBM i 6.1 partitions– POWER6 processor-based servers and blades
XIV performance for IBM i– Performance falls between DS5000 and DS8000,
closer to DS5000– Performance requirements for all workloads moving to
XIV should be carefully evaluated to verify the storage will be able to deliver adequate performance for IBM i
