Re: Pure vs. Power -- MIDRANGE-L

I can't even tell you what Pure is based on the web site, or where Power fits in, or even if it does or does not fit in. It is almost like IBM is trying to position Pure as an architectural panacea, but there is no information on what that architecture looks like. Maybe they are trying to be more solution oriented, and they just say that this androgenous Pure hardware will be able to run the solution, whatever it is. Pay no attention to the man behind the curtain. It would be nice for those who already have IBM systems to have a roadmap into these new technologies.

First rule: Pure Flex uses "Compute Nodes" not those 'blade' thinks, no
no no. :-)

PureFlex includes a V7000 SAN for storage.

PureFlex comes as a full rack that includes all the infrastructure
stuff. This includes fiber switches, power supplies, cooling fans,
V7000, the Flex service module.

A 740 contains its own power supplies and cooling and I think if you
don't intend to use PureFlex for Intel based workloads you'll find the
740 as a MUCH cheaper solution. Can I ask what pushes you to a 740 if
you only need 4 cores and intend to use SAN for storage? Would a 720 do
the job??

P.S. unlikely too many AS/400 people can do a fair comparison of Power
System and PureFlex. :-)

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

hese two implementations.

Thanks,

Mike.
