Eight-bus factory-shipped VNX8000 system
The back-end port numbering for a VNX8000 is set at system test (at the factory). Ports are
identified and numbered, low to high, left to right. The 6-Gb/s SAS I/O modules are in
slots 5 and 10 of Storage Processors A and B.
IMPORTANT
Slot 5, port 0 is reserved for connection to the vault drives.
An eight-bus VNX8000 system with 6-Gb/s SAS I/O modules in slots 5 and 10 supports up
to eight loops using standard x4 (or 4 lane) SAS cables

As described in Table 55, the resulting numbering scheme for an eight-bus VNX8000
shipping from the factory is shown in
page 151. These figures show the 6-Gb/s SAS I/O module slot location, the port location
in the I/O module, and the cable with the cable labels from the I/O module side to the LCC
side on the respective DAE.
