VNX5300 SAS cabling
Note: On the 15-drive DAE, because LCC A and LCC B are reversed, the cable connections into LCC
B and LCC A are also reversed. LCC B will have the tab up, while LCC A will have its tab down. On the
25-drive DAE the cable connections into LCC B and LCC A are identical. Both LCC B and LCC A will
have the tab up.

Cabling between the DPE and optional DAEs uses SAS cables. The connectors on SAS cables
have icons indicating each end.
The SAS ports on the DPE are labeled 0 and 1. Port 0 is connected internally to the SAS
expander that connects all the internal DPE disks. Since Port 0 is already connected internally
to the DPE disks, the first DAE is connected to Port 1 to balance the load on the SAS ports. The
second DAE is connected to Port 0; the third DAE is connected to SAS1, and so forth. Adding
additional DAEs is covered in the VNX5300 Hardware Overview.
