But, to be honest, there is not *that* much difference on a daily basis from SPF 25 to SPF 50: To figure out your level of protection, divide 1 by the SPF number.
NetApp suggests that its FAS8000âs performance grows linearly as nodes are added to a cluster. A six-node FAS6240 â part of NetAppâs top end FAS6200 range, the FAS8000 being a mid-range array â achieved 250,039.67 SPC-1 IOPS.he list price for the system was a smidgen below half a million bucks at $495,652.43, giving a list price/performance rating of $5.76/IOPS. There was 84.2TB of configured storage capacity, using 450GB 10,000rpm SAS drives, and the configuration included two 512GB PCIe flash cards, one per node acting as a flash cache.
