Figure 2: Dual ECB for dual-redundant controller
configurations
StorageWorks Model 2100 and 2200 controller enclosures use
a different type of ECB that does not require an ECB Y-cable
(see
). These enclosures contain four ECB bays. Two
bays support Cache A (bays A1 and A2) and two bays support
Cache B (bays B1 and B2)—see this relationship in
NOTE:
No more than two ECBs are supported within a StorageWorks Model
2100 or 2200 controller enclosure at any time—one for each array
controller and cache set. Blanks must be installed in the remaining vacant
ECB bays for controlling air flow.

IMPORTANT:
When replacing an ECB (see
), match the vacant ECB
bay with the supported cache module. This bay will always be next to the
failed ECB (see
