OCZ Launches Z-Drive 4500 PCIe SSD Series with WXL Software

OCZ Storage Solutions has introduced the enterprise-class Z-Drive 4500 PCIe SSD Series.

Leveraging on 19nm MLC NAND flash, and delivering higher performance when compared to OCZ's Z-Drive R4 Series, it features a more robust architectural design with 800GB, 1.6TB, and 3.2TB usable capacities.

Each model within the new SSD series integrates the new OCZ Windows Accelerator (WXL) software, which is a flash management and caching solution for Microsoft Windows Server applications. It enables IT managers to deliver low-latency flash deployable as a local flash volume, a flash cache for HDD volumes, or as a combination of both.

When deployed for caching, WXL Software performs statistical ‘out-of-band’ processing to intelligently cache the most frequently accessed data on Z-Drive 4500 flash. A cache warm-up and analysis mechanism is also featured enabling important and demanding analytical jobs to be loaded onto the Z-Drive 4500’s flash cache in advance to assure that this critical data is available to the application at the exact time it is needed.

The new Z-Drive 4500 Series are driven by OCZ’s proprietary Virtualized Controller Architecture (VCA) and LSI SandForce SF-2582 processors. Based on SNIA test methodologies, the series delivers industry-leading sustained performance for MLC-based PCIe edge cards including maximum read bandwidth of up to 2,900MBps, maximum write bandwidth of up to 2,200MBps, random 4K block read throughput of up to 252,000 IOPS and random 4K block write throughput of up to 76,000 IOPS.

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.

All drives come backed with a 5-year warranty.
