System component description
This section describes the VNX5400 platform components. Included in this section are
illustrations and descriptions of the front and rear connectors as well as the LED
indicators.
Note: In the following sections, the illustrations and corresponding tables describe these
individual components. These descriptions are for illustrative purposes only.
Installing, replacing, and removing faulted hardware components
Separate documents provide instructions for installing, replacing, and removing hardware
components in the VNX5400 platform. For more information, refer to the respective
document for the correct procedure. These documents are available online at
and go to VNX tasks, then select Add VNX hardware. Next,
follow the steps in the wizard.
Example:
To replace a BBU in the DPE9 of a VNX5400, go to the
Replacing a battery backup unit in a
disk processor enclosure
document for the correct procedures to replace a BBU module in
a DPE9 disk processor enclosure. This procedure is available online at
and go to VNX tasks, then select Add VNX hardware. Next,
follow the steps in the wizard.
VNX5400 front view
As previously described, a Block VNX5400 platform is made up of a 3U DPE while a
File/Unified VNX5400 platform is made up of a 3U DPE, one to two 2U DMEs, and one to
two 1U Control Stations (one optional). The following sections describe the front view
(
) of the VNX5400 platform components.
General
On the front of the VNX5400 platform, the DPE comprises the following components:
◆
Drive carrier
◆
Disk drives
◆
Midplane
◆
Storage processor (SP) CPU
◆
Storage processor (SP) dual fan pack (cooling module)
◆
EMI shielding
Drive carrier
The disk drive carriers are metal and plastic assemblies that provide smooth, reliable
contact with the enclosure slot guides and midplane connectors. Each carrier has a
handle with a latch and spring clips. The latch holds the disk drive in place to ensure
proper connection with the midplane. Disk drive activity/fault LEDs are integrated into the
carrier. The
“3U, 25 (2.5-inch) disk processor enclosure”
section on
provides
more information.
