The storage you configure for a host might include one or more storage area networks (SANs) that use iSCSI. When you configure iSCSI on a host, you can take measures to minimize security risks.
iSCSI supports accessing SCSI devices and exchanging data by using TCP/IP over a network port rather than through a direct connection to a SCSI device. An iSCSI transaction encapsulates blocks of raw SCSI data in iSCSI records and transmits the data to the requesting device or user.
iSCSI SANs support efficient use of the existing Ethernet infrastructure to provide hosts access to storage resources that they can dynamically share. iSCSI SANs are an economical storage solution for environments that rely on a common storage pool to serve many users. As with any networked system, your iSCSI SANs can be subject to security breaches.
