EMC® VNX5300™ Hardware Information Guide
System component description
This section provides the exact details of the Block and File VNX5300 platform
components. These details include illustrations and descriptions of the front and rear
connectors and the LED indicators.
Note:
A Unified VNX5300 platform uses the same hardware as the Block and File configuration
but adds FC, iSCSI, and FCoE I/O connectivity to provide Block services to host
simultaneously so as to provide File services to clients.
VNX5300 front view
As previously described, the Block and File VNX5300 platform is made up of a DPE,
an SPS, one to two Control Stations, and one DME. The following sections will
describe the front (
) view of the VNX5300 platform components
separately.
Note:
In the following sections, the illustrations and corresponding tables describe these
individual components. These descriptions are for illustrative purposes only.
DPE front views
The VNX5300 platform can have one of two versions of the 3U disk drive DPEs
available.
IMPORTANT
!
When calculating the number of drives for your Block and File VNX5300 platform,
the DPE is included in the total drive slot quantity of 120 to 125 drives. If the total
drive slot quantity exceeds 120 to 125, you will not be able to add another DAE.
Refer to
“Disk-array enclosure expansion” on page 57
for more information about
the available expansion DAEs for the Block and File VNX5300 platform.
Each Block and File VNX5300 platform DPE consists of the following components:
◆
Drive carrier
◆
Disk drives
◆
Midplane
◆
Storage processor (SP) CPU
◆
Storage processor (SP) power supply
◆
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. For detailed information, go to
“3U, 15 DPE front view” on page 10
“3U, 25 DPE front view” on page 12
.
Disk drives
Each disk drive consists of one disk drive in a carrier. You can visually distinguish
between module types by their different latch and handle mechanisms and by type,
capacity, and speed labels on each module. You can add or remove a disk drive while
the DPE is powered up, but you should exercise special care when removing modules
while they are in use. Drive modules are extremely sensitive electronic components.
