• AC Power supply; 100-240 V
• DC Power supply

Data Movers Enclosure (DME):
One CPU module consisting of one Intel Xeon 4-core 2.13-GHz processor. The CPU modules in the DME contain the power, fault, and unsafe-to-remove LEDs. Six DDR3 synchronous dynamic RAM (SDRAM) slots support up to 6 GB per CPU module using 2 or 4 GB DIMMs.
Each Data Mover has 4 I/O slots with the first one being a Four Port 8GbE Fibre and the other three can be any combination of the following.

• Two-port 10-Gb/s optical or active Twinax;
• Four-port 1-Gb/s copper;
• Two-port 10-Gb/s RJ45 Base-T iSCSI/IP;

Control Station (CS):
One to two 1U Control Stations supported in a File or Unified Configuration.
On the front, viewing from left to right, the File/Unified VNX5400 platform 1U Control Station includes the following components:

• One DVD-ROM drive
• Two USB 2.0 connectors (not used)
• Front control panel with various buttons and status LEDs
• Four hot-swappable SATA hard drive bays

Disk Array Enclosure (DAE)
The number of DAEs and the disks supported by the VNX5400 platform is variable depending on the type of DAE. Typically, the VNX5400 platform supports up to nine 2U, 25 (2.5-inch) DAEs (for a total of 225, 2.5-inch disk drives), up to fifteen 3U, 15 (2.5- or 3.5-inch) DAEs (for a total of 225, 2.5- or 3.5-inch disk drives), up to one, 3U, 120 (3.5-inch) DAE (for a total of 120, 2.5-inch disk drives), or up to three 4U, 60 (2.5- or 3.5-inch) DAEs (for a total of 180, 2.5- or 3.5-inch disk drives).
The 3U, 120 and 4U, 60 DAEs have separate power supplies and cooling modules (fans). In a 4U, 60 DAE, the primary functionality of an LCC is to be a SAS expander as well as to provide enclosure services to all the disk drives (60 in all).
