I'm looking at the Dell R720 as a host to which I will add a HBA and 10GbE and as much RAM as I can fit in the damn thing. future expandability is a major consideration.
I'm not too worried about how many drives it supports internally but I want at least 8 slots just in case though I will likely only use 5 or 6 of them.
2 in mirror for the TrueNAS OS and 3 or 4 in Raid z for jails and maybe a VM or two, Like I said LOTS of ram, think 512 GB
The big question I have is in regard to the controllers they ship with. as far as I can tell there's at least 3.
1) H310
2) H710
and
3) H710P
I'm pretty sure I want to steer clear of the H710P, but I'm unsure of the other two. I've seen notes of cross flashing to IT or IR mode in a few places and I know you can't use a strict RAID controller with ZFS.
So what I hope is an easy question is does it matter if the controller is 1 or 2. and what do I do to it once I get the wee little bugger in my hands to set up TrueNAS on it.
The HBA will be a LSI 9206-16e and the NIC an Intel x-520 unless someone can point me differently in either regard.
The end goal is a 45 drive pool in raid-z3 drive size to be decided at a later date. I may make it 3 x 15 drive pools but that's a lot to sacrifice in redundancy.
So take your time and get back to me with a well though out answer and maybe a guide to cross flashing which I'm presently unsure of how to do, but comfortable enough to do it once I have a basic guide. Flashed more than enough devices in my time, just not this specific use case.
Thanks in advance
