2.6 Expansion enclosure SBOD controller card
The DS6000 SBOD controller card is only found in the expansion enclosure. Each SBOD controller card contains an independent 22 port Fibre Channel switch. Of these 22 ports, 16 are used to attach to the 16 disks in the expansion enclosure. Four more are used to interconnect with other enclosures, with the remaining two ports reserved for internal use. Figure
on the left are the switch ports that connect either to the server enclosure (to either the disk exp loop or the disk contrl loop) or to the out ports of a previous expansion enclosure. The
two out ports on the right (in light blue boxes) are the switch ports that attach to the in ports of the next expansion enclosure. If there are no extra expansion enclosures then they are not used.
