OCZ Technology Launches Z-Drive R4 PCI Express

OCZ now officially announced the release of Z-Drive Revision 4 (R4) PCI Express (PCIe) storage solutions designed to dramatically accelerate enterprise applications and significantly reduce total cost of ownership in the data center. The Z-Drive R4 product line features OCZs second generation proprietary Virtualized Controller Architecture (VCA) 2.0, providing the utmost in performance, flexibility, durability and enhanced reliability features, allowing data centers, for the first time, to rely on a PCIe-based d SSD as their primary tier one storage solution.

The OCZ Z-Drive R4 is truly unique, melding hardware and software managed solutions with integrated VCA 2.0. This brings traditional SSD technology into a new realm and enhances performance, deployment capabilities, and endurance. VCA 2.0 is a multifaceted virtualization layer and interfaces with the OCZ SuperScale Storage Controller which combines processing and full DMA (direct memory access) cores, as well as internal PCIe, SATA and SAS physical interfaces. When coupled with VCA 2.0 technology, the SuperScale Controller manages critical internal functions such as OCZ’s intelligent Complex Command Queuing Structure (CCQS) with unique queue balancing algorithms. This combination leads to superior performance aggregation and results in significantly higher throughput and reduced burden on the host CPU.

With growing emphasis on cloud computing and big data, enterprises are contending with ever-increasing amounts of data. PCIe-based flash storage systems have the ability to bypass traditional storage overhead, reducing latencies, increasing throughput, and enabling efficient processing of massive quantities of data. A single SuperScale controller equipped Z-Drive R4 is capable of transferring up to 2800 megabytes per second (MB/s) and completing over 500,000 input-output operations per second (IOPS), while a dual SuperScale controller card reaches an astounding 5600 MB/s and 1.2 million IOPS. This level of concentrated performance enables system architects to design more productive infrastructures while lowering costs associated with hardware failure, maintenance, structural footprint, and energy consumption.

With the unique VCA 2.0-based virtualization layer, the Z-Drive R4 offers an advanced set of capabilities designed to solve problems inherent to pure software solutions. The Z-Drive R4 features power fail protection, differentiating the drive from software-based solutions where in-flight data resides in host DRAM and the flash translation layer, thus resulting in loss of data during power interruption.  In addition, VCA enables user-selectable data recovery and non-stop modes with IntegRecover technology ensuring enterprise-class data integrity. Furthermore, the Z-Drive R4 installation in enterprise computing environments is seamless because OCZ VCA 2.0 supports the industry-standard SCSI command set over a PCIe interface. Other features include consolidated SMART support, increased NAND flash life due to OCZ’s lower write amplification and TRIM/SCSI Unmap Support.

The Z-Drive R4 is available in two standard configurations: a half height version designed for space constrained 1U servers and multi-node rackmount servers, and a full height version.  Both configurations support single-level cell (SLC) or multi-level cell (MLC) NAND flash memory with reduced write amplification to extend drive life more than three times the manufacturer’s rating of the NAND.  As with all OCZ enterprise products, customer-specific configurations and functionality are available upon request.
