| Hi, I’m buying several servers to test CEPH and I would like to configure journal on SSD drives (maybe it’s not necessary for all use cases) Could you help me to identify number of SSD I need (SSD are very expensive and GB price business case killer… ) ? I don’t want to experience SSD bottleneck (some abacus ?). I think I will be with below CONF 2 & 3 CONF 1 DELL 730XC "Low Perf": 10 SATA 7.2K 3.5 4TB + 2 SSD 2.5 » 200GB "intensive write" CONF 2 DELL 730XC « Medium Perf" : 22 SATA 7.2K 2.5 1TB + 2 SSD 2.5 » 200GB "intensive write" CONF 3 DELL 730XC « Medium Perf ++" : 22 SAS 10K 2.5 1TB + 2 SSD 2.5 » 200GB "intensive write" Thanks Florent Monthel |
