"…the list immediately shows that all other products are “traditional” NFS servers, not caching products."

Several tested systems use more DRAM and deliver far less performance.

Re: "…1.38ms ORT” is a bit misleading. According to the actual benchmark results available here, the response time was 4.6ms when reaching the 131,591 IOPS; which is significantly higher."

That's how this benchmark works — this is true of ALL SPEC results. When SPEC says "ORT", it stands for "Overall Response Time" and it's consistent across all reported results across all vendors.

Consider…competitive systems need 600-900 spindles to get this many IOPS. Think dollars-per-IOPS and power-per-IOPS! Bottom line, 131K SPEC-ops using only 79 spindles is absolutely stunning.

And they do it without Flash!!!
