How to choose a server which:

  1. has high I/O performance of storage
  2. is highly flexible in terms of adding more storage

So, basically these servers should act as storage servers for OST in lustre architecture.

So, in the process of knowing the above, I also want to know if the processing speed of CPU limits the read and write speeds of a disk. I guess storage controller takes care of the read and write. So, the cpu performance is not needed here? Please correct.

I am looking for HP servers.

Please suggest.

    This is very much an "it depends" question. HP or a consultant versed in parallel file systems can assist you. – ewwhite Jan 22 '16 at 15:15
  • @ewwhite yes, I thought so. Will look into HP pages and support. – GP92 Jan 22 '16 at 15:17
  • Out of curiosity why are you in the "build your own NAS" business? HP (among others) has this stuff figured out probably at a cheaper price than a roll your own solution – Jim B Jan 22 '16 at 17:29
  • @Jim B yes of course, I also just want to learn these things. ;) – GP92 Jan 22 '16 at 17:32
