The 7133 Models D40 and T40 Serial Disk Systems (see Figure 1) are Serial Storage
Architecture (SSA) disk subsystems that can be attached to any computer that provides
support for SSA. Model D40

is a rack-mounted unit that can be installed in a
standard Electrical Industries Association (EIA) 19-inch rack. Model T40

is a
deskside unit.
The 7133 can contain up to 16 SSA disk drive modules (eight at the front and eight at
the back). The disk drive modules are connected to each other in strings of four
modules (two strings at the front of the 7133, and two strings at the back). These
strings can be connected to each other, to strings in other 7133s, or to SSA
attachments (for example, SSA adapters). The SSA attachments can be in separate
using systems or in the same using system.
