between the iSCSI server and the storage device.Iscsi adapter cards are roughly divided into two categories: toe HbA cards and iSCSI HbA cards. The former is cheaper, while the latter is more efficient, but the latter is very expensive. Representative vendors include adaptec, alacritech, Intel, LSI, and Qlogic. Intel focuses on the development of toe HbA cards.
First, the concept of iSCSI iSCSI is a standard for data block transmission on Internet protocols, especially Ethernet, which is a new storage technology based on IP storage theory, which combines SCSI interface technology widely used in storage industry with IP network tec
