Hi, I'm looking for some recommendations for a new "scratch" file server for our cluster. Rough requirements are: - Around 20TB of storage - Good performance with multiple nfs writes (it's quite a mixed workload so hard to characterise further) - Data security not massively important as it's just for scratch / temporary data. It'll just be a single server serving nfs, I'm not looking to go down the luster / pvfs route. I'm thinking of - 3Ware 9690 24 port controller with - 20 1TB SATA disks in RAID5 for the data - 2 500GB SATA disk in RAID1 for the OS and - 2 64GB SSDs in RAID1 for the journal for the data fs. with 2 Quadcore 3.3GHz Xeon processors and 32GB of RAM Anyone have any thoughts / suggestions on this? Thanks, Rob
