"iSCSI solutions can use either the built-in iSCSI software initiator or a hardware iSCSI HBA. The use of software initiators increases the CPU load on the VMware ESX, while HBAs offload this processing time to a dedicated card (as FC HBAs do). To increase the throughput of the TCP/IP transmissions, iSCSI should use jumbo frames. A frame size of 9000 bytes is recommended."
No hace falta que describa la cara que se me ha quedado....
