Five (or so) years ago we wanted to upgrade our 520 (maybe it was a 525). We had just installed a blade chassis with a DS4200 SAN (small to mid-size SAN).

at that time the cost to migrate the 520 to the blade chassis, along with the disk was not a viable option (the disk costs did us in...)

we went ahead and got a 725.

by last year (late 2011), the cost of running the blade chassis (which over 4 years filled up anyway) and the SAN got so expensive we bought new servers (2 big ol' servers running VMware) and a dell EqualLogic SAN.

I shudder to think how management would take a discussion of going back
to blades for the IBM i workload, when the network folks here made quite a good case to toss out what we had...

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 o
f these two implementations.
