Care to share which one? Or just a FreeBSD based one of your own making?
Its just a FreeBSD 8.0 system with a Marvell 8 port SATA card and a couple of TB of of SATA drives. I configured ZFS pretty much with all the default knobs. One of my SATA "drives" is actually outside the box so that I can turn it off to introduce a "failed drive" to the system to evaluate error handling and recovery.
I've been considering NexentaStor Comunity Edition. The boss doesn't
like spending money, and we don't really *need* anything super fancy, but I really like what I hear about ZFS...
For most NAS stuff so far it seems pretty reasonable. Its both not as space efficient and better than the NetApp in terms of total available space becaus the NetApp box lops off like 65GB of every drive in a combination of 'right sizing' and reserving space. ZFS uses the whole drive but has ginormously fat metadata blocks that it mirrors a lot. The Netapp box out performs it in terms of both bulk transfers and IOPs but I've done practically no tuning on the ZFS system.
