Connect SC200/SC220 Enclosures

This section shows common cabling between the SC8000 controller and SC200/220 SAS
enclosures. Locate the scenario that most closely matches the Storage Center you are
configuring and follow the instructions, modifying them as necessary.
An SC200/SC220 cabling chain can contain up to 168 SAS drives, using either type of
enclosure. The maximum number of any one type of enclosure is:
SC200: 14 enclosures

SC220: 7 enclosures

Each SAS IO card supports up to two chains of enclosures. All enclosures attached to the
same SAS IO card must be running at the same speed (all 6 Gb or 3 Gb).
SC200/220 SAS enclosure chains are cabled as follows.
Side A: Enclosures are connected from B port to A port, using the top EMMs.

Side B: Enclosures are connected from A port to B port, using the bottom EMMs.
