Hi Guys,
I have to design a multinode hacmp cluster and am not sure if the design I am thinking of makes any sense.
I have to make an environment that currently resides on 5 nodes more resilient but I have the constrain of only having 4 frames. In addition the business doesnt want to pay for more lpars than they have to. So I would like to go for a 5 active + 2 spare cluster with following setup:
Quote:
F1: A1 + A2
F2: A3 + S1
F3: A4 + S2
F4: A5
A1 could failover to S1
A2 could failover to S2
A3 could failover to S2
A4 could failover to S1
A5 could failover to S1 or S2 (this is the most important environment).
A1 has higher need in resources so I would give S1 the same amount of resources A1 has and all others need about half as much resources, so S2 would have their amount.
Do I have to make all storage (about 3-5 TB / lpar) visible to all nodes or just to the nodes that are intended to takeover the resources.
Does this sound sensible or do I forget anything in this setup? Does anyone maybe run a similar setup and can share his experiences?
I appreciate your comments.
Kind regards
