Dears,
Just to update we are doing 7450 poc now, we had performed 2.5 million IOPS with 4k block size and 70/30 read write less than 5ms avg host response time....the San infrastructure is of 4 Gb/s. 7450 is with 2 nodes and 24 disks and 4 host ports .
2,5 million IOPS on a 2 controller 7450?! I presume you've used 24 SSD's? HP spec says it'll top at +/- 900k IOPS @ 0,7ms latency (4 controller). Sadly, I couldn't find any details on what blocksize or read/write ratio they've used.
Did you test a 7450c or the 7450?
We're thinking about switching from our Lefthand storage to 3PAR and starting our PoC with an 7200c. Because we sell pure SSD storage to our customers, the 7450 was our first target. However, the 7200 is now also being placed as an "AFA" due to it's AFA starter kit and is a lot cheaper. I was only worried about the max. IOPS.
HP now claims a 7200 can handle 300k IOPS @ 1ms, but it doesn't say how many disks are needed to get that much power.
