Re: 9406 515 vs 8203 E4A

Some of those are mutually exclusive. If you add the PCIe slots then you may not add any PCI-X slots. Also you cannot mix PCIx and PCIe slots. Also it's easily possible to connect well more than 380 disks but you pass that 'unsupported' line along the way. And 380 seems like 'enough' anyway. :-)

Also unless you have a VERY good reason to need PCIx slots don't go there.

There are options to add 20 PCIe slots, 24 PCIx slots and 380 SFF disk
slots. That's a whole lotta slots! :)

Joe,

I am not sure what you are reading, but from the words it means there are slots but not cards that come in the slots.

The Older Power5 boxes will have PCI-X adapters so you could have Twinax with an IOP. On the Power7 & Power6 machines there are no PCI-X slots in the CEC, and you can't have a IOP in the CEC. But by now I see very few needs to twinax. If you really need Twinax for printers, I put a 10Zig BosaNova box in, and run it over Ethernet.

Pete, what's with all the optional PCIe/PCI-X slots on these boxes?
What are they used for?

I think the best reason is the 7.2 won't be supported on a 9406-515,
and the 8203-E4A would be the better of the two boxes, but not the
best box. In all honesty, I would look at a 8202-E4D (4-Core), as I
think it will be a better cheaper decision when you take the cost of
the hardware, software, and H/W maintenance over a 3 year life. SWMA
should be the same as all are P05

Tim,

Given these choices, I'd go with the 8203 as it's the Power6 chipset. It's usable and supported life will simply be longer than an aged Power5+...
Your options, CPW, and throughput with the Power6 will be superior (without picking apart CPU feature #'s).

Both are P05 software tier so the OS/LPP's (SWMA) will be the same. Both are V7R1 capable. Others can chime in with hardware MAINTENANCE considerations, reliability, and/or expand-ability ?
