Available Instances of SCSI Routing
You can configure an IP Storage Router with up to 12 SCSI routing services. Each
service needs to be configured with a Gigabit Ethernet IP address, mapping
between iSCSI target names and physical storage addresses, and access control.
When an SR2122-2 is part of a cluster, an instance of SCSI routing can run on
only one storage router in a cluster at any given time. For more information about
instances of SCSI routing in a cluster, see
page 79. For more information about configuring a storage router, see the
appropriate configuration chapters in this document.
