Realistically I can't see why you'd want to risk invalidating the support contracts that you have in place. You'll also take on worrying about firmware etc etc that is normally taken care of!
You will need the caddies as well. We've just done this exercise SFA12KXE and 6TB SAS drives and as well as doubling space we got significantly more performance (after mmrestripe, unless your network is the bottleneck). We left 10 free slots for a potential SSD upgrade (in case of a large increase in inodes or small files).

Users are currently happy with throughput but we need greater capacity as approaching 80%. The enclosures are only half full. Does DDN require adding disks through them or can we get more 6TB SAS through someone else? We would want support contract for the new disks. If possible I think this would be a good stopgap solution until 2020 when we can buy a new faster cluster. Thank you for your feedback. _______________________________________________ gpfsug-discuss mailing list gpfsug-discuss at spectrumscale.org http://gpfsug.org/mailman/listinfo/gpfsug-discuss
