VMware vSphere 5.1 includes backup, deduplication

EMC VFCache delivers in-line deduplication of cached data

"Part of the challenge you have in a VMware environment is there are so many VMs that if you try to crawl through everything to see what data has changed, you'll never get things done in time," said Shane Jackson, vice president of marketing for EMC's Backup Recovery Systems Division. "You need VMware to be able to tell us, here are the three things that have changed since your last backup, so this is what you need to look for on your recovery."

VFCache vSphere integration

Through its VMware ownership, EMC also integrated its VFCache server flash cards with vSphere and announced deduplication on the cards.

The VFCache server cards, used alongside hard disk drives, form a tier of high-performance storage within a server that is accessible via the system's fast PCIe bus. By deduplicating the data before it's written to the flash on the cards, it delivers better cost-per-gigabyte of capacity and extends the life expectancy of the PCIe flash card, EMC said.

VFCache's new interoperability with VMware vSphere vMotion enables data migration between servers using flash.

"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," EMC said in a statement.

In addition, administrators of EMC's flagship VMAX storage array can drill down using VMware's console to see information, such as VFCache's relationships to specific logical unit numbers (LUNs), performance statistics and error condition reports.

Next year, EMC plans to integrate VFCache with the rest of the company's array portfolio, including its midrange VNX line.

EMC also reiterated its support for Cisco's upcoming offering of LSI's customized PCIe Flash mezzanine cards for UCS B-series blade servers. EMC originally announced that support in May.

The latest version of VFCache supports multiple PCIe cards per server. Each PCIe card can hold up to 700GB of data.

Jeff Janukowicz, a research director at IDC, said the annual flash capacity shipped in the enterprise will grow by 20 times by 2016 because of the ever-growing number of applications, the digitization of data, and the growing use of the cloud and Big Data.

"Storage I/O is a critical performance bottleneck for many data-intensive applications," Janukowicz said. "Flash is the essential ingredient in the industry's race for application speed. With these latest updates to EMC VFCache, EMC is delivering efficiency that didn't previously exist for the customer. This addition to its comprehensive Flash portfolio is an important evolution."
