IP Storage - Native iSCSI
FC carries SCSI over Fibre Channel , iSCSI does the same over IP
- iSCSI encapsulates SCSI commands and data over an IP network
- A new breed of native iSCSI Storage devices are being developed
- use standard Ethernet/IP Switches & Routers for interconnectivity
iSCSI SAN provides an end-to-end solution for host to storage connectivity.
This can be a complete alternative to a Fibre Channel SAN, but as we will see
next, it can also complement Fibre Channel solutions by providing connectivity
to distant or less performance demanding hosts.
iSCSI is a lower cost alternative to Fibre Channel as it leverages lower cost
components, builds on existing skills and can integrate with a companies
current management systems.
