The following sections describe the VNX8000 DAE cabling. First, examples of simple
cabling for a two-bus and a four-bus system are described. Then, examples of a more
complicated cabling for an eight-bus and a sixteen bus factory shipped VNX8000 are
described. Finally, examples of an eight-bus and a sixteen-bus upgrade of the VNX8000
are described.
Shown in the upcoming figures
are examples of two-bus and four-bus SAS cabling in an SPE-based VNX storage platform,
the VNX8000. The Storage Processors connect to the DAEs with SAS cables. The cables
connect LCCs in the DAEs of a storage platform in a daisy chain topology. These examples
show how interleaved and stacked DAEs look in their respective racks.

eight-bus and sixteen-bus SAS cabling in an SPE-based VNX storage platform, the
VNX8000. These examples only show the SAS port connections with their respective I/O
modules in the SPE for either eight- or sixteen-bus cabling for a factory shipped VNX8000,
as well as an eight- and sixteen-bus cabling for an upgraded VNX8000.

The VNX8000 platform supports four types of DAEs; a 15 drive 3.5-inch disk 3U enclosure,
a 25 drive 2.5-inch disk 2U enclosure, a 60 drive 2.5- or 3.5-inch disk 4U enclosure, and a
120 drive 2.5- or 3.5-inch disk 3U enclosure. Expansion up to sixty 2U, 25 DAEs (a
maximum of 1,500 2.5-inch disk drives), of up to one-hundred 3U, 15 DAEs (a maximum
of 1,500 2.5- or 3.5-inch disk drives), up to twenty-five 4U, 60 DAEs (a maximum of 1,500
2.5- or 3.5-inch disk drives), or up to twelve 3U, 120 DAEs (a maximum of 1,440 2.5- or
3.5-inch disk drives) is supported.
IMPORTANT
Do Not
connect more DAEs than the VNX8000 platform can support. When calculating the
number of drives for your VNX8000 platform, if the total drive slot quantity exceeds
between 1,500 depending on type of DAE installed, you will not be able to add another
DAE.
