What is the recommended performance of a SAN for DCRUM ?
For example, is this SAN performant enough for DCRUM :
disc 15krpm and response time (average calculated during one month) =
read = 1,51 ms (PLS) ; 0,94 ms (CSB)
write = 1,62 ms (PLS) ; 1,68 ms (CSB)
Is there a minimum performance value ?
Interesting question. I haven't looked at performance test for a year or so and last time I did it I was using the CAS Benchmark Tool Overview
As you know, it doesn't list the disk latency but merely lists an index number for you to compare against our recommended standard profile.
When I managed to get more than 1 in the tests I was using a SSD on PCI.
Most of them report valuse such as read/write time and throughput - Get a POC kit and run some test or install the CAS Benchmark Tool Overview on this SAN you have and run the tests.
