System component description
This section describes the Block VNX5100 platform components. Included in this section
are illustrations and descriptions of the front and rear connectors as well as the LED
indicators.
First, the components of the VNX5100 are described in two views.
◆ “VNX5100 front view” on page 10
• “DPE front view” on page 10
• “3U, 15 disk drive DPE front view” on page 12
• “3U, 25 disk drive DPE front view” on page 13
◆ “VNX5100 rear view” on page 14
• “DPE rear view” on page 14
• “Standby power supply” on page 27
Note: In the following sections, the illustrations and corresponding tables describe these
individual components. These descriptions are for illustrative purposes only.
Then, the “Disk-array enclosure” on page 31 describes the two types of DAEs available for
the VNX5100.
VNX5100 front view
As previously described, the Block VNX5100 platform is made up of a DPE and a 1U SPS.
The following sections describes the front (Figure 2 on page 7) view of the VNX5100
platform components.
DPE front view
The Block VNX5100 platform can have one of two versions of the 3U disk drive DPE.
When calculating the number of drives for your VNX5100 platform, the DPE is included in
the total drive slot quantity of 75 drives. If the total drive slot quantity exceeds 75, you will
not be able to add another DAE. Refer to “Disk-array enclosure” on page 31 for more
information about the available expansion DAEs for the VNX5100 platform.
Each Block VNX5100 platform DPE comprises the following components:
◆ Drive carrier
◆ Disk drives
◆ Midplane
◆ Storage processor (SP) CPU
◆ Storage processor (SP) power supply
◆ EMI shielding
