Lots of great hardware knowledge in this thread! I'm also making the move to 10Gb.
I'm adding a 3rd host to my deployment and moving to Glusterfs on 3 nodes, from my current NFS share on a separate storage server.
Each of the 3 nodes has dual E5-2640 V4s with128Gb ram. I have some hardware choices I would love some advice about:
- Should I use Intel X520-DA2 or X710-DA2 nics for the storage network? No significant price difference. The hosts are running oVirt Node 4.2. I hope to use them in bridge mode so that I don't need a 10Gbe switch. I do have a single 10Gbe port left on my router.
- the hosts have 12Gbps 520i SAS cards, should I spec 6 or 12 Gbps SSD drives? Here there is a large price difference, also large difference between Enterprise performance, Enterprise mainstream, and Enterprise entry. I'm not sure how to estimate the value of those different options in a Glusterfs deployment.
The workload is pretty I/O intensive with fairly small read/write operations (under 128Kb) on windows VMs.
Any obvious weak links with this plan?
We run Dell Poweredge R720s and R730s with 32 GB of RAM and quad Xeon
processors. Storage is provided by Dell MD3800i and Promise arrays
using iSCSI. The network is all 10 gigabit interfaces using 802.3ad
bonds. We actually just upgraded from 1 gigabit NICs since there were
some performance issues with storage causing high IOwait on VMs. I'd
recommend avoiding 1 gigabit if you can.
