VNX8000 DAE cabling
Interleaved or stacked cabling with forty DAEs in a VNX8000 File/Unified platform
The cabling for a VNX8000 File/Unified platform is the same as the block system. The only
difference is that the File/Unified components (CS0, CS1 (optional), and any DMEs) would
have to be accounted for. In other words, if you are upgrading from an existing Block
system, from 4U to 10U of space should have been made available in your first rack. If you
are installing a new VNX8000 File/Unified system, then the connections for Bus 0, Bus, 1,
Bus 2, and Bus 3 in an interleaved or stacked system would be the same as described for
the VNX8000 Block from page 134 to page 139 of this guide.
Note: It is recommended that for load balancing purposes that you use as many buses
across your DAEs as possible.
IMPORTANT
The examples for the Block or File/Unified systems described in this guide are only
examples of how you can cable you VNX8000 system whether it is a Block or File/Unified
system.
