Bought some cheap SSDs and just grabbed systems and platters I had around for it. Testbedding and getting some experience with the self hosted engine, since I’d like to move to it once it’s released. Also looking forward to testing native gluster on this setup.

Sounds odd, I know, but couldn’t get good support for a community nextenta server I inherited. I was having driver level box lockup issues with openSolaris that I couldn’t resolve. So I rebuilt it with linux, imported the pool, and haven’t looked back or had a storage failure since.

Native ZoL, it’s just a big fat 10g NFS server for the host nodes. It’s been solid since Ovirt 3.1 or so. Been using linux (old Slackware hand here) too long to turn back to the daemon side ;) I use macs and OS X for the desktop to get my mach Kernel bsd-ish fix, so the even darker side? :)
