Hi all,
I've got a smallish virtualized environment running vSphere 4.1 with storage provided over NFS via a single HP X1600 NAS (running Solaris). I'm starting to look at ways in which I can improve the resilience of this and remove any single points of failure.
I'm fairly sure I can sort out the resilience on the OS, host and networking level, but storage is something that's not obvious at the moment.
At the moment I'm considering buying another X1600, whacking fibre in everything and then using multipathing from VMware to the storage devices (you can't multipath NFS I don't think). However, it's not clear to me how you keep the data in sync between the two NAS units. Would I be better off using the other NAS as a hot-standby and just doing periodic ZFS exports from NAS1 to NAS2?
What are my options here?
