What is iSCSI?

iSCSI, or internet SCSI, is an IETF standard which maps SCSI blocks into Ethernet packets. Fundamentally, the iSCSI protocol is a method for transporting low latency SCSI blocks across IP networks.

How can iSCSI Help Me?
iSCSI also allows you to build storage area networks over IP using something you already know and use everyday: Ethernet. In this way, iSCSI removes the limitations of direct attached storage, including the inability to share storage resources across servers and to expand capacity without shutting down applications.

Benefits of iSCSI SANs

• High Availability
  Multiple paths between servers and storage enable a constant connection, even if some lines go down.
• Scalability
  The switched architecture of SANs enable IT managers to expand storage capacity without shutting down applications.
• Maximize Storage Resource Investment
  SANs allow you to share disk and tape devices across heterogeneous platforms.
