Kaminario has introduced the 4th generation of its K2 enterprise-grade storage array. Unlike the company’s earlier K2s, which supported DRAM, SSD, and HDD, the fourth generation K2 is all-flash, based on SAS SSDs alone. The company says that its new approach reduces the cost of ownership by supporting a larger capacity within a smaller footprint while requiring less power and cooling.
The SSDs are MLC products, rather than the SLC ones used in earlier K2s, allowing Kaminario to reduce the cost. Although the SSDs Kaminario uses come with a 5-year warranty, the K2′s SPEAR operating system optimizes flash endurance allowing Kaminario to offer a 7-year warranty. (SPEAR is Kaminario’s scale-out performance storage architecture operating system software.)

These are a part of the UltraStar line.
Whereas HGST’s first-generation UltraStar SAS SSDs used SLC flash, the new SSDs are based on 25nm MLC flash but offer the same warranties as HGST’s prior generation. Even so, performance for the new SSDs is significantly faster than that of their SLC-based predecessors, with no reduction in wear or lifetime specifications.
These SSDs are the first to support Continue reading
