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

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)


IBM Power Systems

5

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

Redundant VIOS Support with Client-side MPIO

Redundant VIOS Support– Enables IBM i 6.1 partitions to utilize redundant VIOS partitions with 1 set of

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
