1.1.2 Easy Upgrade
The 7131 Storage Tower has a minimum configuration of 2 hot-swap hard disk drives installed in the hot-swap bays. As the user's
requirements change, you can expand your storage capacity or upgrade to higher performing devices by installing any of the options listed
in Table 1-2 and Table 1-1.
As a further upgrade, a single-ended to differential (SE/DIFF) card allows you to attach a longer system SCSI cable, an additional host
system, or an additional 7131 Storage Tower. The SE/DIFF card must be installed by your IBM service representative.
Instructions for upgrading your 7131 Storage Tower are in Chapter 5, "Upgrading the 7131 SCSI Multi-Storage Tower."
