Appendix B.
Deploying iSCSI host interface
controllers on the IBM System
Storage DS5000 series
This appendix reviews planning considerations when deploying IBM System Storage DS5000
storage subsystems in environments with mixed-host-interface requirements. The new
Internet Small Computer Systems Interface (iSCSI) feature that has been added to the IBM
System Storage DS5300 and IBM System Storage DS5100, and included in the IBM System
Storage DS5020. Therefore, a number of new areas must be factored in when deploying the
storage subsystems when you plan to use iSCSI. In the mixed interface environment (also
referred to as SAN tiering), other iSCSI considerations include networking, performance, and
security.
The DS5000 series of storage subsystems now support intermixed iSCSI and FC host
interfaces. Using both interfaces provides a greater degree of flexibility in configuration and
deployment of a consolidated storage solution to individual servers or hosts attached to a
SAN.
