Hi friends,
my actual hardware setup per OSD-node is as follow:
# 3 OSD-Nodes with
- 2x Intel(R) Xeon(R) CPU E5-2603 v3 @ 1.60GHz ==> 12 Cores, no
Hyper-Threading
- 64GB RAM
- 12x 4TB HGST 7K4000 SAS2 (6GB/s) Disks as OSDs
- 1x INTEL SSDPEDMD400G4 (Intel DC P3700 NVMe) as Journaling Device for
12 Disks (20G Journal size)
- 1x Samsung SSD 840/850 Pro only for the OS
# and 1x OSD Node with
- 1x Intel(R) Xeon(R) CPU E5-2650 v3 @ 2.30GHz (10 Cores 20 Threads)
- 64GB RAM
- 23x 2TB TOSHIBA MK2001TRKB SAS2 (6GB/s) Disks as OSDs
- 1x SEAGATE ST32000445SS SAS2 (6GB/s) Disk as OSDs
- 1x INTEL SSDPEDMD400G4 (Intel DC P3700 NVMe) as Journaling Device for
24 Disks (15G Journal size)
- 1x Samsung SSD 850 Pro only for the OS
As you can see, i am using 1 (one) NVMe (Intel DC P3700 NVMe – 400G)
Device for whole Spinning Disks (partitioned) on each OSD-node.
When „Luminous“ is available (as next LTE) i plan to switch vom
„filestore“ to „bluestore“ 😊
As far as i have read bluestore consists of
- „the device“
- „block-DB“: device that store RocksDB metadata
- „block-WAL“: device that stores RocksDB „write-ahead journal“
Which setup would be usefull in my case?
I Would setup the disks via "ceph-deploy".
Thanks in advance for your suggestions!
- Mehmet
