1.2 SF72 Storage Enclosure Overview
The SF72 is a storage enclosure (Figure 1–2) designed to be installed into
an SF200 storage array or certain system cabinets. A single enclosure
holds two or four RF72 disk integrated storage elements (ISEs). Each
disk ISE is independently controlled by the SF72 OCP. The power supply
in the enclosure provides the dc power and cooling for the disk ISEs.
