The MLC-based 800GB OCZ Z-Drive 4500 Series PCIe FH/HL Enterprise Solid State Drive features a robust Virtualized Controller Architecture (VCA) Technology, delivering industry-leading sustained performance so that users achieve fast file transfers, boot-ups and benefit from a more responsive storage experience. The Z-Drive 4500 Series is also integrated with OCZ’s Windows
Accelerator (WXL) Software – a flash management and caching solution for Windows Server-based applications. It enables IT managers to dramatically improve the performance and latency on SAN and DAS systems by intelligently caching the most frequently accessed data. Through deep statistical ‘out-of-band’ processing, a Z-Drive 4500 can selectively determine what data to cache for I/O acceleration while avoiding processing in the data path itself. The result is expedited I/O, Windows applications spending less time waiting for data, SAN resources available for other applications, and a reduction in latency-related bottlenecks.
For flash-based virtualization, the Z-Drive 4500 Series works in conjunction with OCZ’s VXL Virtualization Software distributing flash cache resources on-demand across virtual machines (VMs) to accelerate application performance. It distributes the flash between VMs based on need making sure that no VM inefficiently occupies flash when it could be better used elsewhere in the environment. As a result, the Z-Drive 4500’s flash cache is optimally utilized at all times regardless of how many VMs are running concurrently, data traffic to and from the SAN is reduced, and critical data is locally available in the Z-Drive 4500 card for immediate use by VMs.
