  "Nimbus announced the availability of its new FlexConnect technology
   across the entire S-class family, providing triple active-active
   10 GbE network controllers for an unprecedented 120 Gbps of available
   bandwidth and 12 x 10 GbE ports, all from a single appliance."

  "The new S1000, building on the existing S250 and S500 models, takes
   advantage of higher density 34 nm EMLC NAND, offering 24 x 400 GB
   hot-swappable flash blades per S-class shelf for 10 TB of solid state
   capacity. All S-class systems now support increased scalability up to
   600 flash blades in one file system for a total of 250 TB, making it
   the highest capacity, most scalable flash storage system on the market"

  "Until now, organizations using NAS-based storage have been limited to
   "add in" Flash drives to existing RAID enclosures or MLC-based offerings
   for their Ethernet-based infrastructure.  Solid Access is changing the
   equation by offering a purpose-built 10 Gigabit Ethernet (10GbE) solution
   for truly high performance NAS-based application requirements. Providing
   1.2 or 2.4 TB of available storage capacity in a 2U rack mount enclosure,"

ポートは 10GbEですが、ファイルシステム (NAS) の件は記載されてませんね。
※これは SSDと DRAM cacheを組み合わせるのがウリみたいです。
