Bollinger, who uses QLogic HBAs that perform both TCP and iSCSI offload, says he'll migrate to 10Gb/sec Ethernet for the trunks between university buildings.
"10Gb/sec to 100Gb/sec is in our planning process and further validates
| our decision to deploy iSCSI," says Kash at the U.S. Army Corps of Engineers. "I'm comfortable that iSCSI is going to take over from Fibre Channel, and [that] it will no longer be considered a low-cost, lower performing alternative."
Rima says "we can do TCP Offload with the TCP Offload on our NetApp boxes," adding that "10Gig should allow us to scale up quite a bit."
Besides the use of existing Ethernet switches, adapters and common Category 6 cabling, users have seen other advantages. "The ROI of iSCSI is hard to measure, but our complaints from users on performance issues are practically non-existent now," says Safeway Insurance Group's Leather. "That's a huge ROI. In our business, if someone has trouble with our Web site while they're writing insurance, they won't wait for us, they'll just go to the next insurance carrier. You can't measure the lost business."
