Hello,
We have been running OpenIndiana (and its various predecessors) as storage servers in production for the last couple of years. Over that time the majority of our storage infrastructure has been moved to Open Indiana to the point where we currently serve (iSCSI, NFS and CIFS) about 1.2PB from 10+ servers in three datacenters . All of these systems are pretty much the same, large pool of disks, SSD for root, ZIL and L2ARC, 64-128GB RAM, multiple 10Gb uplinks. All of these work like a charm. However the next system is going to be a little different. It needs to be the absolute fastest iSCSI target we can create/afford. We'll need about 10-12TB of capacity and the working set will be 5-6TB and IO over time is 90% reads and 10% writes using 32K blocks but this is a data analysis scenario so all the writes are upfront. Contrary to previous installs, money is a secondary (but not unimportant) issue for this one. I'd like to stick with a SuperMicro platform and we've been thinking of trying the new Intel S3700 800GB SSD's which seem to run about $2K. Ideally I'd like to keep system cost below $60K. This is new ground for us. Before this one, the game has always been primarily about capacity/data integrity and anything we designed based on ZFS/Open Solaris has always more than delivered in the performance arena. This time we're looking to fill up the dedicated 10Gbe connections to each of the four to eight processing nodes as much as possible. The processing nodes have been designed that they will consume whatever storage bandwidth they can get. Any ideas/thoughts/recommendations/caveats would be much appreciated.
