Introducing the Enclosure
This chapter describes of the StorageWorks Enclosure 4200 family of low voltage
differential (LVD) disk enclosures (see Figure 1–1 and Figure 1–2). These enclosures
support Wide-Ultra and Wide-Ultra2 small computer system interface (SCSI)
protocols. The internal bus supports only LVD drives. The external bus (the enclosure to
the host controller bus) supports either Wide-Ultra2 (LVD) and or Wide-Ultra
single-ended (SE) SCSI protocols.
