Part 1

Because of the success and widespread adoption of Fibre Channel, iSCSI technology is often overlooked. But with 10 Gigabit Ethernet and data center bridging technology picking up steam, the gap between iSCSI and Fibre Channel is closing, making iSCSI a more viable alternative for handling Ethernet storage. In this podcast, Demartek president Dennis Martin discusses some of the latest technologies affecting iSCSI performance, including data center bridging, iSCSI multipathing, CHAP and IPsec security, iSCSI offload adapters and jumbo frames. Listen to the podcast or read the transcript below to get more insights from Martin.
