Hi, I use ZFS on my backup servers. I can't say we've ever had power failures because they're in a datacenter, but I would invest in a decent UPS if it's a regular occurrence. Hard drives don't generally like having power suddenly removed..... ZFS on OpenIndiana will give you nice features like file system compression, dedupe, snapshots and constant checksumming of of in-use blocks. I've never used Hammer before, but HammerFS doesn't appear to offer compression yet. Just my opinion, but I'd say ZFS is more widely used than Hammer.
