Hello,
I wanted to know which is a better alternative for a cluster of 48 nodes
(dual processor) that is working 24x7 for life science problems dealing with
extensive I/O's (small files) for performance. The kind of I/O's i am
talking about is small file read and writes say (10-20kb) each and 10000's
of these operations simultaneously on the file system. How well does a
distributed file system like GPFS on SAN works or a NAS storage works.
We are in the process of designing a cluster for life science related
problem that will work on 10'000's of file's simultaneously from across the
linux cluster and we are hung up on the storage options the pro's and con's
of (GPFS on SAN) or (NAS device). If some body could point me to a right
direction it would be great because as i read from few sites they say NAS
devices are more preferred option but i could'nt find the reasons to support
either one of them.
Thanks
ASB
