Hi to all, I'm new to Ceph and i want to create a Cluster for Production with HP ProLiant DL380p Gen8 servers, the idea is to use 4 of this servers to use as OSD's, and then 3 x HP ProLiant DL320e Gen8 servers for MON. The Data network would be on 10GbE switches and 1Gb the management. Below is the description of each of the servers: HP ProLiant DL380p Gen8: 2 x Intel Xeon E5-2630v2 @2.6Ghz (6-cores) 2 x 64GB RAM 2 x 450GB SAS 15K in RAID-1 configuration for the OS 2 x 100GB SSD in RAID-1 configuration for the Journals 8 x 4TB SATA 7.2K to use as 8 x OSD's (32TB raw) 1 x HP Ethernet 10GbE 2-port 530SFP+ Adapter 1 x HP Ethernet 1Gb 2-port 332T Adapter HP ProLiant DL320e Gen8: 1 x Intel Xeon E3-1240v2 @3.4Ghz (4-cores) 1 x 32GB RAM 2 x 450GB SAS 15K in RAID-1 configuration for the OS 2 x 1.2TB SAS 10K for Logs 1 x HP Ethernet 10GbE 2-port 530SFP+ Adapter 1 x HP Ethernet 1Gb 2-port 332T Adapter I want to know if someone more or less had a similar configuration and to know what are the performance numbers (some benchmarks) for reads and writes, maybe also some iozone or bonnie++ outputs, with several processes (1..10), and different block sizes. Also if anybody had some recommendations or tips regarding the configuration for performance. The filesystem to be used is XFS. I really appreciated the help. Thanks in advance, Best regards, German Anders |
