OCZ Tweaks Proprietary Virtualized Controller Architecture

Paul Lilly

Solid state drives appear to be simple things. Slap some NAND flash memory on a circuit board, add a SATA interface, and cover the contraption with a case. There's a bit more to it than that, and for OCZ's enterprise PCI Express and SAS SSD solutions, the real magic happens in its proprietary Virtualized Controller Architecture (VCA). Now in its second generation, OCZ says its revamped VCA supports even more enterprise features and is the next step in the evolution of virtualization layers for solid state storage.

"VCA 2.0 enables industry-leading configurable performance aggregation along with a rich enterprise feature set not found on competitive products," said Ryan Petersen, CEO of OCZ. "With its scalable performance, TRIM and SCSI unmap support, and enhanced management tools, VCA 2.0 provides superior reliability and superior performance, in a plethora of OCZ's easy-to-deploy storage solutions."

In OCZ's enterprise PCI-E devices, VCA 2.0 supports the creation of a virtual pool of logical units (LUNs) and offers configurable performance aggregation, a combination OCZ says simplifies data management without impacting performance. Another big feature addition is user-selectable data recovery and non-stop modes for data protection. VCA 2.0 also supports complete power fail protection and stores all metadata in nonvolatile memory.

VCA 2.0 technology will be available with the launch of upcoming workstation and enterprise-class PCI-E SSDS, including the RevoDrive 3 and Z-Drive R4. You can read more about VCA 2.0's mojo here (PDF) .
