Hi Satish,
just one caution here.
I tried DL380 G8 with NVME Samsung 960 Pro drive. The latter (despite
pretty good overall performance numbers) hardly suits for BlueStore
WAL/DB deployment since it handles (f)synced writes very slowly. Which
is crucial for DB/WAL.
The root cause IMO is due to the lack of Power Loss Data Protection (or
whatever you name it).
I'm not sure that's the case for your drive though. Just be careful when
using such consumer drives.
Thanks,
Igor

Folks,

5 x HP DL360p G8 / 32 core 2.9Ghz / 32GB memory / 2x10G nic (server has 10 HDD slot)
3 x HP DL 460c blades for Monitor ( I'm not very worried about resousr here)
15 x SSD 500GB ( Samsung EVO)
15 x SATA 1TB 7.5k
My requirements is for openstack vm just for block storage,
1. how should layout my drives ?
2. How many sad for journal?
3. Should I put all SSD on single box or should spread out?
3. For avarage load does SATA 7.5k enough ?
4. Do you think DL 360p G8 would be good enough or I need more powerful?
My all application is mostly web / small DB / some CPU crunching application ( need CPU core)
