Disk-array enclosure
Disk drives
92 VNX5500 Hardware Information Guide
The disk drives for the 4U DAE are encased in cartridge-style enclosures. This enclosure is
used so that varied types and sizes of disk drives can be supported. Each cartridge has an
easy-to-pull and push latch. The latch allows you to quickly and efficiently snap-out a disk
drive for removal and snap-in for installation.
Two drive sizes are supported in the 4U DAE:
2.5-inch 6-Gb/s SAS, 6-Gb/s NL-SAS, or Flash disk drives (hot-swappable)
◆
3.5-inch 6-Gb/s SAS, 6-Gb/s NL-SAS, or Flash disk drives (hot-swappable)

location of the disk drives, fans (cooling modules), and LCC A.

Disk drive layout
Looking at the 4U DAE from the front and above, the inside of each DAE has physically
printed labels located on the left and the front sides of the DAE. These labels describe the
rows (or banks) and the columns (or slots) of where the disks are installed in the DAE. The
banks are labeled from A to E, while the slots are labeled from 0 to 11. When describing
the layout of disks within a 4U DAE, the interface format for the DAE is called B_E_D. That
is, B indicates the bus, E the enclosure, and D the disk. For example, you could have an
interface format of 0_1_B11. This format is interpreted as bus 0, enclosure 1, in row
(bank) B, in slot number 11. Looking at the 4U DAE from the front and above,
page 93 shows you the disk drive layout of the 4U, 60 DAE.
Note: The labels for the banks, slots, and LCCA shown in
physical labels in the 4U DAE.
1. You can add or remove a disk drive while the DAE is powered up, but you should exercise special
care when removing modules while they are in use. Drive modules are extremely sensitive
electronic components.
