Introduction
Introduction
2 VNX7500 Dense Rack Installation Addendum
VNX systems are available utilizing the dense-storage capabilities of the 60-disk
dense disk-array enclosure (DAE7S). This DAE is 4U high and can include up to 60
disks in one drawer. This dense-storage system is installed in a cabinet (40U-D) that is
5” deeper than a standard EMC cabinet.
The VNX7500 system includes the following components in the cabinet:
◆ 1U or 2U Standby Power Supply (SPS)
◆ 2U Storage Processor Enclosure,
◆ one or more Disk Array Enclosures, either 3U or 4U.
The VNX series of products includes a number of different types of DAEs. Only the
3U DAE and the 4U DAE are supported in the dense rack configurations.
◆ a 3U 15-slot 3.5” disk DAE (Figure 1)
◆ a 4U 60-slot 3.5” disk DAE (Figure 2 on page 3)
In the dense rack configuration, the use of a 3U DAE as DAE 0 will mean that the
system will use a 1U SPS. See Figure 3 on page 4. Systems using the 4U 60-slot DAE for
the vault drives must use a 2U SPS. See Figure 4 on page 4.

Introduction
Note: The 4U 60 slot DAE loads disks from the top, unlike the front-loading 3U DAE. For more
information on DAEs, see the VNX7500 Hardware Information Guide.
The VNX7500 can include a combination of the 3U 15 slot and the 4U 60 slot DAEs.
Any configuration using a 4U 60 slot DAE7S disk array enclosure requires a deep
rack.

Unpacking and cabling
VNX7500 Block
Configuration
Unpacking and cabling
The VNX7500 in a dense rack configuration arrives fully cabled from the factory. The
only cabling that may be required involves cabling between cabinets and cabling the
system to the network. See the cabling directions in the appropriate VNX7500
installation guide and the instructions for adding additional DAEs and additional
buses in the VNX7500 Hardware Information Guide for details.
The VNX7500 has 4 SAS ports available in the SAS I/O module in slot 0 of each SP.
The VNX7500 supports an optional second SAS I/O module in slot 1. Thus, a
VNX7500 system can have its disk capacity configured over 4 buses up to 8 buses.
Note: There is no provision for moving disks or enclosures from one bus to another. It is
possible to add additional storage to new or to existing buses.
The system as delivered in the cabinet will have the number of disks load-balanced
over the buses.
The VNX7500 Block configuration, with its multiple buses, can provide a convenient
means for utilizing a very dense use of rack space. See Figure 5 on page 6, for example.
Depending upon how your system was designed and configured, you may have over
500 disks within one cabinet.

Additional storage, in second or third cabinets, will depend upon the number of 4U
DAEs in the first cabinet, whether space has been reserved for a Unified upgrade, and
whether Flash drives have been used in the system.
If the VNX7500 Block configuration has space reserved for future File upgrade to a
Unified configuration, space for the File hardware components will be provided at the
top of the system cabinet. This allows for easier access and service to these
components. See Figure 6 on page 7 for an illustration of a dense VNX7500 Unified
system.

The File and Unified configurations include the 2U storage processor enclosure (SPE),
a 1U or a 2U standby power supply (SPS), up to four 2U data mover enclosures, one
or two 1U Control Stations, DAE 0, and [optional] disk-array enclosures (DAEs) for
holding additional storage.

Because a VNX7500 system can support up to 1000 drives, a VNX7500 File or Unified
dense system can include up to six of the 4U 60 slot DAEs in the first cabinet.
Additional DAEs can be added in additional cabinets.
