EMC VFCache first to deduplicate server Flash Cache

EMC VFCache™ solution delivers in-line deduplication of cached data — an industry first.


Date: 31 Aug 2012

EMC Corporation says that it has set a new benchmark for enterprise Flash efficiency by delivering in-line cache deduplication on EMC® VFCache™, a server Flash caching solution that turbo-charges performance in mission-critical Oracle, Microsoft and SAP application environments—up to 3X in some cases. EMC also extended its leadership in VMware environments, with new interoperability between VFCache and VMware® vSphere® vMotion to enable seamless and flexible movement of virtual machines in environments accelerated by VFCache. EMC continues to invest in the industry's most comprehensive Flash portfolio, delivering all the performance benefits of Flash without sacrificing the benefits of network storage—high availability, disaster recovery, data integrity, and reliability. This unique approach is why EMC shipped a record amount of Flash capacity in the second quarter of 2012.

Technology Highlights:
· More Efficient: EMC is leveraging its leadership in deduplication for backup environments and applying that expertise to caching. With the addition of in-line deduplication of cached data for a larger effective cache, the cache size of VFCache is significantly increased in environments with applications leveraging high deduplication gains. This capability delivers better cost per gigabyte and extends the life expectancy of the card.
· Deeper Integration: VFCache is now more deeply integrated at the virtual, storage and server levels to maximize mission-critical application environments. VFCache now delivers:
o Automation of VMware vSphere vMotion environments for efficient administration. VFCache interoperability with vSphere vMotion makes it faster and easier to achieve continuous up-time and fluid operations, complete environment maintenance, and enable seamless migrations—helping customers accelerate their journey to the cloud. Through the EMC VSI plug-in for VMware vCenter™, EMC enables VMware administrators to handle other priority tasks, and ensures business continuity with no system downtime when migrating operations.
o Simplified management, more streamlined operations, and greater visibility into operational information. EMC VFCache contains the foundational capabilities to provide EMC VMAX storage administrators with more operational information, such as VFCache's relationships to specific LUNS, more performance statistics, and error condition reporting. These capabilities will support superior storage management relative to other solutions in the industry, and represent another key step toward EMC's vision of high performance automated tiered storage. Customers continue to benefit from VFCache's turbocharged performance with the protection for which EMC storage is trusted around the world. EMC is also committed to integrating VFCache with the rest of EMC's storage portfolio—including EMC VNX™—in 2013.
o Support for Cisco's upcoming offering of LSI's customized PCIe Flash mezzanine cards for UCS B-Series Blade Servers (announced in May 2012).
· Better Performance: The latest version of VFCache supports multiple PCIe cards per server and delivers more capacity options—with support for new 700GB PCIe cards—to cache larger working sets and offer greater performance to customers. In addition, EMC continues to optimize and advance the performance of demanding enterprise workloads by lowering latency through tuning of the VFCache caching algorithms.

In addition to VFCache, customers with mixed workloads can choose from EMC's hybrid arrays armed with EMC FAST™ (Fully Automated Storage Tiering) technology that automates the movement of "hot" data onto Flash drives and moves "cold" data to high-capacity drives. For VDI or test and development environments with 100% "hot" data, customers will be able to leverage all-Flash arrays that will deliver the raw performance required with innovative new technologies from "Project X" through EMC's acquisition of XtremIO (announced in May 2012). For persistent data stores with performance intensive workloads—including high-frequency trading or online gaming—EMC will offer "Project Thunder", a server network attached appliance built entirely of high-speed PCIe Flash (announced in February 2012).
