2U, 25-drive DPE component overview
The 25-drive DPE is two rack units (U), 8.9 cm (3.5 in.) high, 79.2 cm (31.2 in.) deep,
and includes slots for twenty-five 2.5-in. drives.
The DPE consists of the following components:
lDrives
lMidplane
lStorage processor assembly
lPower supply module
lEMI shielding
Drives
Each drive consists of one drive in a carrier. The 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 drive in place to ensure proper connection with the midplane. Drive activity
and fault LEDs are located on the front of the enclosure.
SAS and SAS flash drives are supported. The drives are populated in the system from
left to right.
Note
The first four drive slots are reserved for system drives, and should not be removed.
You can visually distinguish between drive types by their different latch and handle
mechanisms and by type, capacity, and speed labels on each drive. You can add or
remove a drive while the DPE is powered on, but you should exercise special care
when removing modules while they are in use. Drives are sensitive electronic
components.
Midplane
The midplane separates the front-facing drives from the rear-facing SP assemblies. It
distributes power and signals to all components in the enclosure. The SP assemblies
and drives plug directly into the midplane.
Storage processor assembly
Each DPE contains two SP assemblies. The SP assembly is the intelligent component
providing the compute capability of the DPE. Acting as the control center, each SP
assembly includes status LEDs.
Storage processor assembly power supply module
Each SP assembly contains a power supply module that connects the system to an
exterior power source. Redundant power supplies can keep the entire DPE running if
one power supply fails. The power supplies include LEDs to indicate component status.
A latch on the module locks it into place to ensure proper connection.
EMI shielding
EMI compliance requires a properly installed electromagnetic interference (EMI)
shield in front of the DPE drives. When installed in cabinets that include a front door,
the DPE includes a simple EMI shield. Other installations require a front bezel that has
a locking latch and integrated EMI shield. Remove the bezel or shield to remove and
install the drives.

About 4-port cards
The 4-port card is an optional component located within the embedded module. There
are two supported 4-port cards: the 25GbE 4-port card and the 10GbE BaseT 4-port
card.
The 25GbE 4-port card supports 1GbE SFP to RJ45, 10GbE or 25GbE SFP28, 25GbE
passive TwinAx, and 10GbE active or passive TwinAx. Depending on the installed SFP
or TwinAx cable, the following speeds are supported: 1GbE, 10GbE, and 25GbE. The
ports may be configured individually with TwinAx or any of the supported SFPs.

Nonmaskable interrupt (NMI) button
The nonmaskable interrupt (NMI) button is a recessed button located on the
embedded module, which is used to reset the system password or force a system
reboot.
Use a bent paper clip or pen to press the recessed button. Press the button for
approximately 2 seconds to reset the password. The SP assembly fault LED blinks blue
when the password has been successfully reset.
Press the button for 10 or more seconds to force a system reboot.

DPE I/O module types
I/O module installation priority
There are two I/O module slots per SP assembly: slot 0 and slot 1. Slot 0 has a 16 lane
PCIe channel, and slot 1 has an 8 lane PCIe channel.
Populate new I/O modules in the following order to take advantage of the increased
speed on slot 0. If two I/O modules are ordered, use the same installation priority for
both I/O modules.

4-port 25GbE Optical I/O module
The 4-port 25GbE Optical I/O module is an Ethernet I/O module that is used to serve
Ethernet network traffic and iSCSI block protocol to hosts for the platform. The I/O
module uses an optical 10G or 25G capable SFP+ connection to a host or switch port.
4-port 16Gb Fibre Channel I/O module
The 4-port 16Gb Fibre Channel I/O module comes with four optical ports, one power
and fault LED, and a combination link and activity LED for each optical port. This I/O
module can interface at speeds of 4, 8, and 16 Gb/s FC for host or initiator layered
connections.
4-port 10GbE BaseT I/O module
The 4-port 10GbE BaseT I/O module can interface at speeds of 1 Gb/s and 10 Gb/s
and supports both IP(file) and iSCSI (Block) on the same SP assembly. Ports can be
configured as both IP and iSCSI simultaneously. The I/O module comes with four 10-
Gb/s RJ-45 ports, one power/fault LED, activity LED, and link LED for each port.
DPE component descriptions
DPE I/O module types 15

4-port 12Gb SAS backend I/O module
Where supported, the 4-port 12Gb SAS backend I/O module comes with four x4 lane
mini-SAS high density (HD) ports, one power and fault LED, and a combination link
and activity LED for each port. Install thisI/O module into the SP assembly to provide
additional SAS buses. Labeled 12Gb SAS v1.
Note
The optional back-end 12-Gb/s SAS module is only supported on Unity 480F, Unity
680F, and Unity 880F systems.
The 4-port 12Gb SAS backend I/O module can also be configured to support x8 lane
cabling for the 80-drive DAE by combining ports 0 and 1 as back-end 2, or ports 2 and
3 to create back-end 4. The I/O module can also be configured to support both x4 lane
and x8 lane back-ends simultaneously.
Note
If the 4-port 12Gb SAS backend I/O module is to be configured for x8 lane cabling, the
x8 lane cable must be inserted into the I/O module before persisting it. If the x8 lane
cables are not inserted into the I/O module first, all four ports default to x4 lane ports.
DPE power supply
NOTICE
The power supply used in your system must meet the system power requirements and
must be the same type of power supply to be used in both nodes. Do not mix power
supply types.

Storage processor assembly internal components
Included within the SP assembly are the following components:
lDual inline memory modules (DIMM)
lM.2 SSDs
lInternal battery backup module
lFan module
Dual inline memory modules
Twenty-four, 288-pin DIMM sockets support up to 12 DDR4 DIMMs, capable of up to
96 GB, 192 GB, or 384 GB of memory, depending on the model.
Internal battery backup module
The SP assembly includes a Lithium-ion (Li-ion) internal battery that powers the
associated SP assembly during a power event.
M.2 SSD
Each SP assembly has two slots for M.2 SSD on a M.2 SSD adaptor located between
DIMM slots 5/17 and 6/18. One M.2 SSD is used for general system operations, while
the other M.2 SSD is used for vaulting.
Fan module
Six redundant fan modules connect to the motherboard within the SP assembly to
provide continuous airflow through the front drives and through the rear of the SP
assembly to keep the components at optimal operating temperatures.
Note
The SP assembly performs a protective thermal shutdown if two cooling modules fault
within the same SP assembly.
