Definitions for This IBM Presentation
� Upgrade = new model which keeps the same serial number– Example: POWER6 570 9117-MMA to POWER7 770 9117-MMB
� Migration = new model which does not keep the same serial number– Example: POWER6 550 8204-E8A to POWER7 750 8223-E8B
• Insight: Legal & accounting rules require at least
20% of the original asset to be reused to be
classified an upgrade to the same asset. • IBM uses a serial number to track an asset and
uses an average config definition to determine if
a model upgrade path can be offered.
• Each client has to determine how to classify their new model acquisition. (if an upgrade or not)

Is protecting a serial number important?
� To some clients, it does not matter. To others it does matter.
� Serial number might matter:– Additional documentation/tools for moving to newer server
– Financially works better for depreciation/budget
– IBM software entitlements moves easily to newer server (especially IBM i)
– IBM 5250 entitlements (IBM i) moves easily to new server
– May ease discussions with ISVs if licensing serial number specific
� Serial number might not matter:– Financial impact to depreciation/budget not an impact
– IBM software transferable (with a bit more effort)
– IBM 5250 more transferable now to POWER7 with RPQ
– ISV software licensing not impacted by serial number

POWER6 system unit I/O• What are you keeping that won’t fit in the future POWER7 system unit?
• Example: 3.5-inch disk drives (POWER7 server = SFF in CEC)
• Example: PCI-X adapters (Most POWER7 servers are PCIe only)
• IVE / HEA differences to consider?POWER6 I/O drawers
• Put I/O from POWER6 server which you are keeping that won’t fit in POWER7 system unit into a 12X I/O drawer
• Move off HSL/RIO I/O drawers – replace with all 12X I/O drawers• Remove all IOPs. Move to all smart PCI adapters.
Get the I/O
ready
This step more limited if you are migrating from a POWER5 server to a POWER6
server. There are no 12X I/O drawers, PCIe slots, SFF disk, etc on a POWER5 server.

POWER7 I/O Upgrade Considerations
� All the newer IBM I/O drawers (12X), disk, SSD and PCI adapters used on POWER6 supported on POWER7 servers (non-Blade statement)
– May need to move 3.5-inch SAS drives and PCI-X adapters
� Older I/O on POWER6 servers, but not on POWER7 servers
– RIO/HSL I/O drawers
– SCSI disk smaller than 69GB or SCSI drives slower than 15k rpm
– QIC tape drives
– IOPs and IOP-based PCI adapters (IBM i)2749, 5702, 5712, 2757, 5581, 5591, 2790, 5580, 5590, 5704, 5761, 2787, 5760, 4801, 4805,
3709, 4746, 4812, 4813
– Older LAN adapters: #5707, 1984, 5718, 1981, 5719, 1982
– Older SCSI adapters: #5776, 5583, 5777
– Telephony adapter: #6412

Upgrades - PEX & Side-by-side RPQ�When you need to run two systems in parallel while upgrading …
–Option A PEX (Power Exchange)• Flexible duration
• Additional software licensing required
• Results in machine with different serial number
–Option B Side-by-Side RPQ• For POWER7 servers with upgrade path & with “roll-in
roll-out” upgrade• 1 - 8 weeks duration
• No additional IBM Power Systems licensing required
Other non IBM Power Systems licensing may be needed
• Results in machine with the same serial number
Done
