When one needs to provision a new Windows Server 2012 RTM/R2 cluster one of the time factors to keep in mind is the Cluster-Aware Update runs that will happen once the cluster has been brought up.
The above is a new Windows Server 2012 R2 four node cluster that we finished configuring last night.
The first CAU run started around 2300Hrs. As can be seen each node took about an hour to run through the process.
Even though we are not too far into the product release cycle for R2 one needs to keep in mind the update maintenance process if one is not using an up-to-date image for deployment. This would be especially true if deploying 2012 RTM or 2008 R2 clusters.
Cluster node configuration:
- Intel Server System SR1695GPRX2AC with RMM
- Intel Xeon Processor X3470, 32GB ECC, 120GB Intel SSD RAID 1, Dual Intel SAS HBAs
