i. SCSI – 介绍 i. SCSI-enabled Hosts • i. SCSI – Internet SCSI Protocol. . . is a new transport protocol for SANs. . . leverages an Ethernet infrastructure. . . represents choice for SAN connectivity. . . is very complementary to Fibre Channel. . . Enables lower cost SAN infrastructure • Many new i. SCSI solutions i. SCSI Catalyst 6500 IP Network Midrange server and application connectivity Blade server SAN connectivity High density server cluster connectivity Longer distance SAN connectivity Note: Can’t change speed-of-light limitations • i.
