Riverbed's Granite Speeds Up WAN Storage to Drive Consolidation
The file transfer acceleration technology could help enterprises cut local storage out of remote sites

IDG News Service — Riverbed Technology plans to make enterprise data centers look like local storage at branch offices with Granite, a new accelerator technology the company is announcing on Wednesday.
Granite is designed to carry out block data transfers across WANs (wide-area networks) without the many back-and-forth exchanges that make such movements time-consuming now. Granite can essentially achieve the same thing with blocks of data that Riverbed's Steelhead appliance does with applications, slashing wait times at branches and letting enterprises centralize their storage, executives said at a press event earlier this week in San Francisco.
Granite will play a major role in a plan by international law firm Paul Hastings to go from 16 data centers to four, said Searl Tate, the firm's director of network engineering, who spoke at the event. Paul Hastings has been working with the product since the alpha testing stage. "The story of consolidation is compelling," Tate said.
In addition to moving large files around the world at LAN speed, Granite will let remote users boot up virtual desktops over long distances, a process that often takes 30 minutes or more and in some cases is not even possible, said Eric Wolford, executive vice president and general manager of the company's products group.
The technology is set to ship by the end of March and will be available both as a standalone appliance and as software on a Steelhead appliance. Granite is a major initiative for the company, "the next Riverbed inside Riverbed," Wolford said. Riverbed made its name with WAN application acceleration that helped enterprises centralize their servers in many cases, and Granite will address some additional situations, he said.
When servers have to remain at the remote site to run certain applications, Granite allows IT departments to at least house the data centrally. Retrieving it to the Riverbed appliance for local use is quick thanks to the new technology, according to Riverbed.
"This is going to help project whatever disk is in the data center out to the edge, so that the edge can think the disk is actually local," Wolford said.
When a server needs to retrieve data from a storage array, where it usually resides in many different blocks, typically the server requests the bits from each block in sequence. Over a WAN, that process can take a long time because messages and data need to travel over a long distance. Using its awareness of the file system, Granite allows the remote server to retrieve all the required blocks of data in one round-trip transaction, Wolford said.
