OCZ Technology Group has announced the release of the second generation of its proprietary virtualized controller architecture (VCA). VCA 2.0 supports a rich enterprise feature-set enabling unprecedented flexibility, increased performance, and the reliability required for high throughput storage systems.
In OCZ's enterprise PCIe devices, VCA 2.0 supports the creation of a virtual pool of logical units (LUNs) and features best-in-class configurable performance aggregation, simplifying data management without impacting performance, to provide clients with an easily deployable total solution. According to OCZ, VCA 2.0 is the only virtualization layer in the industry with TRIM and SCSI unmap support which enhances the sustained performance by significantly reducing the overhead associated with garbage collection.
Additionally, VCA 2.0's user-selectable data recovery and non-stop modes allow for unprecedented data protection, while consolidated SMART support provides system administrators with advanced features for monitoring, analyzing, and reporting device attributes. Unlike other flash virtualization layers, VCA 2.0 also supports complete power fail protection. In the event of unexpected system power loss, OCZ's enterprise power fail protection completes all in-progress transactions, protecting the integrity of all active data.
When combined with OCZ's SuperScale storage controller, VCA 2.allows certain direct memory access (DMA) and data management functions, including OCZ's unique command queuing and queue balance algorithms, to be handled by the onboard processing core. This results in higher performance and reduces the burden on the host CPU.
"OCZ's proprietary VCA technology 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. 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," said Ryan Petersen, chief executive officer of OCZ Technology Group.
VCA 2.0 technology will become available with the launch of OCZ's upcoming workstation and enterprise-class PCIe SSDs, including the RevoDrive 3 and Z-Drive R4.
