Hi all, I'm planning to deploy a new Ceph cluster with IB FDR 56Gb/s and I've the following HW:
*3x MON Servers:* 2x Intel Xeon E5-2600@v3 8C 256GB RAM 1xIB FRD ADPT-DP (two ports for PUB network) 1xGB ADPT-DP Disk Layout: SOFT-RAID: SCSI1 (0,0,0) (sda) - 120.0 GB ATA INTEL SSDSC2BB12 (OS-RAID1) SCSI2 (0,0,0) (sdb) - 120.0 GB ATA INTEL SSDSC2BB12 (OS-RAID1) *8x OSD Servers:* 2x Intel Xeon E5-2600@v3 10C 256GB RAM 1xIB FRD ADPT-DP (one port for PUB and one for CLUS network) 1xGB ADPT-DP Disk Layout: SOFT-RAID: SCSI1 (0,0,0) (sda) - 120.0 GB ATA INTEL SSDSC2BB12 (OS-RAID1) SCSI2 (0,0,0) (sdb) - 120.0 GB ATA INTEL SSDSC2BB12 (OS-RAID1) JBOD: SCSI9 (0,0,0) (sdd) - 120.0 GB ATA INTEL SC3500 SSDSC2BB12 (Journal) SCSI9 (0,1,0) (sde) - 120.0 GB ATA INTEL SC3500 SSDSC2BB12 (Journal) SCSI9 (0,2,0) (sdf) - 120.0 GB ATA INTEL SC3500 SSDSC2BB12 (Journal) SCSI9 (0,3,0) (sdg) - 800.2 GB ATA INTEL SC3510 SSDSC2BB80 (Pool-SSD) SCSI9 (0,4,0) (sdh) - 800.2 GB ATA INTEL SC3510 SSDSC2BB80 (Pool-SSD) SCSI9 (0,5,0) (sdi) - 800.2 GB ATA INTEL SC3510 SSDSC2BB80 (Pool-SSD) SCSI9 (0,6,0) (sdj) - 800.2 GB ATA INTEL SC3510 SSDSC2BB80 (Pool-SSD) SCSI9 (0,7,0) (sdk) - 3.0 TB SEAGATE ST3000NM0023 (Pool-SATA) SCSI9 (0,8,0) (sdl) - 3.0 TB SEAGATE ST3000NM0023 (Pool-SATA) SCSI9 (0,9,0) (sdm) - 3.0 TB SEAGATE ST3000NM0023 (Pool-SATA) SCSI9 (0,10,0) (sdn) - 3.0 TB SEAGATE ST3000NM0023 (Pool-SATA) SCSI9 (0,11,0) (sdo) - 3.0 TB SEAGATE ST3000NM0023 (Pool-SATA) I would like to have an expert opinion on what would be the best deploy/config disk pools and crush map? any other advice? Thanks in advance, Best regards, *German*
