WAN acceleration vendor SilverPeak is aiming to narrow the Jumbo sized gap with the latest version of its core VXOA software. Silver Peak's Virtual Acceleration Open (VXOA) was first announced in July of 2011 as a way to deliver software based WAN acceleration capabilities.
"Most systems can replicate faster if they can use Jumbo Frames," Tinsley said.
An Ethernet Jumbo Frame is a packet size that can be up to 9,000 bytes. In contrast, normal Ethernet frames that traverse a WAN are only 1,500 bytes or less in size.
"We've added the capability to essentially translate large Jumbo Frames from the local side in a data center, chop them up into 1,500 byte packets for the WAN and then reassemble them into the larger frames on the other side," Tinsley said.
As such, two storage arrays, in two different data centers will be able to communicate with each other with Jumbo Frames. According to Tinsley, storage arrays that are enabled for Jumbo Frames typically run 50 percent faster.
