Hey there,
I've built a few production SANs with freenas, all which have been virtually flawless for the past five years or so.
It's been a while though (about 2.5 years) since my last SAN, and I wanted to bounce my setup off the community. Hopefully someone out there can give me the green light.
We're going to use 2 or 3 cluster nodes on Server 2012 R2, probably Dell R630's w/ 2x 2.6 GHz 10 Cores and 256GB RAM each. They'll have dual SFP+ which we'll twinax to the SAN (we will save on power with no switch, which is doable in this small cluster size).
The SAN will probably be a R730xd with the 24x 2.5 HDD config.
We have about 40 VMs that we need to migrate over to this new cluster from a handful of separate inefficient hyper v nodes, most of which have their own local storage.
What I'd like to do is setup this new R730xd SAN with 15x 600GB 10K SAS drives, which I'll split up into 3x RAIDZ pools. We're going to use the remaing 9 bays for individual SSDs for a few customers that are paying for those.
We will use a couple Intel PCI 750's for the SLOG, and another for l2arc cache.
My main question is, would we be better off, performance wise, striping those three RAIDZ pools together? My thought was to put each of our three nodes on a segregated iSCSI portal pointing to each pool, to separate traffic. But I wonder if striping and connecting all three nodes to the same portal/volume, would be better.
There's obvously much more to say about this, but any input and feedback would be invaluable. Thanks all.
