One of the challenges of offering a unique product is that sometimes it can be difficult for outsiders to classify it with other solutions in the market. So we see, from time to time, published articles that either put the K2 in the wrong bucket or don’t describe the K2’s capabilities completely.
Such is the case with a recent blog by Ruben Spruijt that discusses different types of SSD solutions including hybrid file systems, Flash-only arrays and server-side Flash. While it is true that the Kaminario K2 offers a single enclosure for blade servers connected with Flash, it is not accurate to include the K2 in the server-side Flash category. Spruijt does not specifically call out Kaminario as a server-side SSD solution, but it appears that way from the mention.
Kaminario Makes All Solid-State SAN Storage — Absent a category for all solid-state SAN storage to include Flash and DRAM, Spruijt should have mentioned the K2 in his Flash-only array discussion. As my colleague Eyal Markovich said, “server-based PCIe cards are, by nature, local to the server, so they cannot serve as part of a server cluster. That means they’re out as an SSD solution for running Oracle Real Application Clusters (RAC) or an SQL Server instance as part of a Microsoft Cluster. Since the K2 is SAN-based, it fully supports these clustering configurations.” This is just one example why readers should understand that the K2 is a solid-state SAN storage array versus a server-side SSD solution.
