We will propose a few JS22 blade AIX servers as GPFS NSD server nodes (with DS4800 disk) for a customer running multimedia work...
Their workstations are Linux (about 30-40 in number). Should we include them as GPFS node (non-NSD server) or should we just NFS mount the file system from GPFS cluster?
If we include it in GPFS cluster:
- Need to pay GPFS license
+ No recovery action needed if NSD server fails (next NSD server in the list will takeover)
If we use NFS mounted:
+ No GPFS license
- Need to do manual load balance (client group A mount from node X, client group B mount from node Y, ...)
- Need to do manual mount/unmount if NSD server fails
How about the performance(receive data directly from NSD server via GPFS interconnect vs NFS mount)?
How many % do we get from NFS mount vs included it in the cluster? (eg. 70% performance?)
Also, are there other things that we may need to consider?
Thank you very much,
