RE-ENGINEERING CLUSTER ARCHITECTURE
RE-ENGINEERING CLUSTER ARCHITECTURE.
Has anybody gone through the process of reducing or changing from multi-node
cluster to single node with a hot-standby server?
We are running Storage Foundation 3.5 cluster server but have license for
4.x. Our need is to utilize current hardware which means reducing server
count in the clusters by half. The server farm consists of (six) v480's;
(2) nodes per cluster represented as DBTIER; APPTIER and ISTIER...
The DBTIER is ACT/ACT and the others ACT/PASS. My intent is to either go
to a single node cluster per tier, consolidating the ISTIER with the APPTIER
and using the remaining single server for standby. So I would have (1) node
per tier (2) clusters and a hot standby. Or, creating (2) node cluster on
(1) tier and hot standby.
I see the main issue being the service groups, disk groups and volumes crossing
between clusters for one and the second option being how to gracefully migrate
and converge three clusters into one.
I need to understand the high level steps to make the approach sound feasible.
Can someone respond if you have an idea of the objective I am trying to reach
and any source of information that lays out a plan of action?
