Hello all. I’ve been following the list for a long time and rarely post anything, but now wanted to chime in.

There are a lot of “legacy” software that are not engineered for the cloud and only runs on Windows. The developers of these kinds of products seem to often think clustering/HA as a solved problem with VMware and not bother building it to the product itself. But VMware replication/HA/Fault Tolerance is complex, finicky and often out of reach for very small businesses due to cost. I’m not very familiar with HAST and DRBD, but seems like the added complexity might sometimes outweigh the expected benefits there as well. I’ve read varying success with OmniOS as a built in storage provider for ESXi through iSCSI or NFS. Ideally this would be built in to Illumos/ZFS. I already use SmartOS and Znapzend for replicating KVM VM’s between hosts, but it’s only crash consistent. VSS or file system quiescing support would improve this. In small business space, there usually isn’t a need for a full lock-step fault tolerance type automated HA with shared storage and what have you, so ability to bring up replicated VM’s on a backup host in a consistent state would go a long way. I’ve just recently set up replication between ESXi hosts with Veeam and ZFS send would just be so much faster and easier to set up and use. Better yet, LX Zone type ability to run Windows software directly in a zone would be a dream, but probably quite impossible.
