Kaminario’s Performance and 7-Year Flash Life Warranties

Kaminario LogoToday Kaminario added a performance guarantee and a 7-year warranty to its arsenal.  The company introduced its “Consistency Under Failure Guarantee” which ensures customers will see no more than a 25% drop in performance during a system failure.  This means that critical operations and applications can continue to run at near-standard performance despite the failure of an SSD or even an entire node.  Kaminario president Dani Golan told The SSD Guy last week that this is a conservative guarantee, and that few customers see more than a 10% degradation during failure tests in their own production systems.

As for the 7-year flash endurance warranty, no matter which SSD Continue reading

Kaminario Goes All-Flash

Kaminario K2Kaminario 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.)

The original K2 was built with a focus on Continue reading

New White Paper: Enterprise Reliability, Solid State Speed

Kaminario's K2 SystemThe SSD Guy has just posted a new white paper to the Objective Analysis home page.  It’s about Kaminario‘s approach to solid state storage.

Yes, this is a commissioned white paper, but that doesn’t preclude my taking the same unbiased approach my clients have come to expect.  Kaminario has re-thought how SSDs should be used in storage, and that deserves some attention.

It’s only six pages, but even so I will condense the content for this post:  Flash is tricky Continue reading
