Connect SC280 Enclosures
Dell Compellent 81
Dual Controllers, Two SC280 and Two SC200/SC220 Enclosures,
Two Chains
This illustration shows two SC8000 controllers cabled to two SC280 Enclosures and two
SC200/220 enclosures in two chains.
To add redundancy with multiple IO cards, add a second SAS IO card. Create the A ‐ sides
of each chain on the IO card in slot 2 and create the B ‐ sides of each chain on the IO card in
slot 3. If an IO card, cable, enclosure, or controller fails, at least one side of a chain continues
operating. IPC is optional in this configuration.
When connecting different types of enclosures, each type must reside on its own chain. For
example, do not mix SC280 Enclosures and SC200 Enclosures in the same chain. In
addition, all enclosures must be 6 Gb enclosures.
Note: The maximum storage space is 1 petabyte, regardless of the number or type
of enclosures.
