Hello,
I've been looking for solutions in regards to setting up a highly available storage system. Here's my end goal: I would like to setup a FreeBSD iSCSI target (server), and provide iSCSI storage to virtual machines. Now the virtual machines need to be highly available, so I can't have the iSCSI server being a single point failure and that's why I need the iSCSI target to replicate to another server.
So far, I've been looking into HAST: http://www5.us.freebsd.org/doc/handbook/disks-hast.html
HAST seems like a promising solution. Have any of you guys worked with HAST before. If so, what are your thoughts on it as far as performance and reliability goes?
I've also thought about replicating ZFS snapshots to a different server, however, I'm not too sure how well that would work, specially being that I would need to keep the data as much in sync as possible.
I would like to hear your input in regards to building a highly available storage system/distributed filesystem.
