Drive Chassis Numbering
Depending on configuration, an F-Class Storage System can include up to 10 drive chassis. A
drive chassis houses 16 drive magazines. Drive chassis are first placed sequentially below controller
node 1 (controller node 3 in an F400) and then sequentially above controller node 0. Drive chassis
are numbered as shown in Figure 29 (page 31).
Figure 29 Numbering of Drive Chassis
NOTE: For systems occupying multiple cabinets, drive chassis numbers continue at the bottom
of the next cabinet and progress through the top of the cabinet.
Figure 30 (page 32) and Figure 31 (page 32) illustrate individual drive chassis components and
how they are numbered. Fibre Channel ports in the Fibre Channel Arbitrated Loop (FC-AL) at the
sides of the drive chassis enable connection to the controller nodes.
