I am planning on building a 24 disk backup server this week. Dell R730 with MD expansion shelf. I'm mainly looking for any gotcha's or things to look out for.

1. networking: mellanox 25Gb + Intel 10Gb

2. 24x 26TB SATA disks

3. vDev configuration: I was planning on doing two sets in RAIDZ-2. Should I go smaller sizes and more vDevs? Again this is just a backup server that I'm copying data FROM our main SAN, probably every 4 hours or so and then doing ZFS snapshots. There is a SLIGHT SLIGHT possibility in the future that if the SAN takes a dive, that we might have to use this for "production AV" use temporarily while we get the SAN back. Thinking about using SMB sharing to the Macs if we have to.
