Hi all,
I'm just about to set up a three node Proxmox cluster with Ceph.
The three machines will all be:
IBM System X3550 M4
Dual: 2.60 GHz Eight (octa) -Core Xeon (E5-2650 V2) - 3.40GHz Turbo Boost Speed - 8GT/20MB
Memory: 192GB - (24 x 8GB) - DDR3 ECC Reg
RAID: Standard M5110 Onboard RAID 512MB FBWC
Network Interface: 4 x 1GB + additional Dual Port Onboard 10GB SFP+ NIC
4 x 960GB SM863a SSD
I will be using the 10GB interfaces without a switch as per the Proxmox documentation, just linking them together with DAC.
I'm thinking that with the above I should get fairly decent throughput and latency but I'm wondering, should I hold off a little while and wait for the bluestore or will the performance enhancement not be that great?
The other big question is should I keep the M5110 RAID or replace with HBAs, I'm seeing differing opinions depending on which thread you read my initial instinct would have been to replace the RAID with 9211-8is.
Thanks
Daz
