Chapter 1.

Disk attachment technology

This chapter describes basic disk attachment methods in the context of the IBM System
Storage DS3000. We discuss the following technologies:

򐂰

Fibre Channel (FC)

򐂰

Serial-Attached SCSI (SAS)

򐂰

Internet SCSI (iSCSI)

Fibre Channel has traditionally been used to attach storage subsystems in midrange and
large scale environments. However, as the DS3000 products are geared towards SMB and
departmental environments, SAS and iSCSI attachment technologies are supported as well.
