I am trying to figure out how big I should make my volumes; we have an Equallogic PS4100X and we are running vmware esxi 4.1 (free version) with about 50 vmware images of various sizes (20gb - 300gb).
I am trying to figure out if I should create say two large volumes (Development and Production) and leave it at that, or if I should create my volumes based on how many the individual components can support (mostly the PS4100X).
We had a technician that suggested that we run 8-9 vmware images per volume. However, I dont have any hard facts, written, to back the statement.
Is there some math formula that I could use to figure out? i.e. ( 8 vmware images needing 4000 IOPS, and the PS4100X supporting 4200 IOPS per volume), etc... Perhaps the issue is not IOPS, but connections. Etc. Whatever the limitation may be?
I looked through all the questions and came across a similar question, but I need a statement to the limitation, or a formula to help me compute. Could someone help me? This is my first time using a ISCSI, I dont have any experience.
