Good afternoon all,
We are upgrading our storage backbone, moving it off of our common 1 GBit backbone to a 10 dedicated storage backbone.
When this happens, we will need to re-ip the storage domains with to IP address of the 10 GBit release.
For a period of time, as we upgrade the rest of our hardware, we may have to operate both the original and the new IP addresses.
Some gotchas:
1. My controller is at level 4.3, but some of my my compute nodes are at level 4.2 because they have older Penryn class processors. We didn't plan the upgrade - it happened because our controller's hard drive failed and took the cluster with it.
Practical question:
1. Can I simply operate the same storage domain on two IP addresses on different physical networks eg. 10.10.1.x and
10.10.10.x
?
2. Is an alternative solution to operate two storage domains from the storage appliance, and migrate the storage from the 1GBit domain to the 10 GBit domain over time, then drop/abandon the old storage domain once everything is on the 10 GBit? I have plenty of storage to do this.
3. Is there a better way I haven't thought of?
