The OCZ Z-Drive R4 Series represents a turning point in the evolution of PCIe attached solid state storage by merging the best feature sets of both the pure hardware and pure software based approaches to data management. Designed and manufactured for a wide range of enterprise environments including cloud computing and data centers, the Z-Drive R4 features OCZ's Virtualized Controller Architecture (VCA) 2.0, providing the utmost in performance, flexibility, durability and enhanced reliability, allowing data centers to rely on a PCIe-based SSD as their primary tier one storage solution for the first time. Additionally, the Z-Drive R4's level of concentrated performance enables system architects to design more productive infrastructures while lowering operating costs associated with hard drive technology.
VCA 2.0 supports the industry standard SCSI command set and, among a litany of other things, provides highly efficient performance aggregation due to OCZ’s exclusive Complex Command Queuing Structure (CCQS), that handles balancing with OCZ's unique Queue Balancing Algorithm, that extends the NAND flash life at a block level, manages redundancy, and is the software interface with the host system.
Z-Drives integrate seamlessly with servers at the system bus and kernel level, creating a new flash memory tier and dramatically increasing throughput and application performance all while slashing capital and operating costs. The OCZ Z-Drive R4 Series is available in half height and full height configurations (half height form factor for CM84 Version).
The Pinnacle of Storage Performance The OCZ Z-Drive R4 Series CM84 eliminates I/O and bandwidth bottlenecks by delivering up to 2,000 MB/s Max Read, 2,000MB/s Max Write and 250,000 IOPS 4KB Random Write performance. It delivers the performance of thousands of hard disk drives in a single server.
Proprietary Virtualized Controller Architecture (VCA) 2.0 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. Included are OCZ’s exclusive command queuing and queue balancing algorithms, which can be handled by the onboard processing core for higher performance and reduced burden on the host resources. VCA 2.0 is also the only virtualization layer in the industry with TRIM and SCSI unmap support to enhance sustained performance and provide greater endurance by significantly reducing the overhead associated with garbage collection. Furthermore, VCA 2.0 offers consolidated SMART support and provides system administrators with advanced features for monitoring, analyzing, and reporting device attributes.
SuperScale Storage Accelerator Unique to OCZ The OCZ SuperScale storage controller combines processing and full DMA (direct memory access) cores, as well as internal PCIe, SATA and SAS interfaces, facilitating scalable performance in enterprise & datacenter applications. This controller, combined with VCA 2.0 provides unique benefits to users by allowing certain DMA and data management functions including OCZ’s unique command queuing and queue balance algorithms to be handled by the onboard processing core, resulting in higher performance and reduced burden on the host resource.
Superior Reliability, Endurance, & Security Features The OCZ Z-Drive R4 Series provides clients with world-class reliability features including superior data fail recovery, intelligent block management & wear-leveling for increased endurance, advanced security with 256-bit AES encryption support, and strong error correction for enhanced data integrity.
