Re: Pure vs. Power

Mike,

Some of your terminology is throwing me off. Flex "compute nodes" are not
"blades", for instance. And as far as I know they don't come in 2-core
configurations. It sounds like you may be better off down-sizing from a 550
to a 720, or possibly one 720 for IBM i and another for AIX.

I think that Pure Flex configurations are really geared for very large
data centers and massive parallel compute capacity.

Subject: Pure vs. Power

So, after many year I might have convinced management to upgrade our aging
Power 5 550 machine. I initally was looking at a four core 740, with two
cores for i OS and two to support older AIX workloads. In the end, it
looks like it might only be i OS on Power running on two Power cores. With
some other projects going on in the division, the PureFlex system is being
thrown out as another option. This configuration would have three or four
x86 blades and one Power blade running two cores. The politics of the
situation has me possibly axeing the x 86 blades and looking at a PureFlex
system only with one Power blade. So, I guess what I'm looking for is some
feedback on a 740 with 2 cores or a PureFlex blade with 2 cores. Both
solutions would most likely be using DASD out of our V7000 system. I
haven't seen any configs yet so I can't answer part numbers, memory, etc
but I guess I'm looking for an AS/400/iSeries/system I person who might know
more about the comparision of t
hese two implementations.

Thanks,

Mike.
