Hi Majid

It is better to go for HA for both OSS and MDS. You would need 2 nos of MDS and 
2 nos of OSS (identical configuration).
Also use latest Lustre 2.10.1 release.

Subject: [lustre-discuss] 1 MDS and 1 OSS

Hello 
We are in process in procuring one small Lustre filesystem giving us 120 TB  of 
storage using Lustre 2.X.
The vendor has proposed only 1 MDS and 1 OSS as a solution.
The query we have is that is this configuration enough , or we need more OSS?
The MDS and OSS server are identical  with regards to RAM (64 GB) and  HDD 
(300GB)

Thanks
Majid
