VNX5700 DAE cabling
Note: If your VNX5700 platform was not cabled at the factory, refer to the cable wrap guide
(“Cable label wraps” on page 95) that came with your VNX5700 platform for the correct

Note: Each cable end includes a symbol to denote the direction the cable needs to
connect to. The cable end that has a single circle symbol is the input end. While the cable
connector with the single diamond symbol is the output end.
Interleaved cabling with twenty DAEs in a VNX5700 Block platform
Figure 87 on page 100 shows a second example of a VNX5700 Block platform with twenty
DAEs (all are 2U, 25 disk drive DAEs) or a VNX5700 platform with a total of 500 disk
drives. This example has two 40U racks with the both racks having ten DAEs each. This
example shows the interleaved cabling with two 40U racks, the first rack having ten DAEs
and the second and final rack having ten DAEs.
Note: In the example in Figure 87 on page 100, the 2U, 25 disk drive DAE is used. If you
want to use the 3U, 15 disk drive DAE, three 40U racks would be necessary. Each 40U rack
can accommodate up to thirteen DAEs (ten DAEs per Bus) without difficulty. So, in this
