Safety warnings
EMC VNX5400 Hardware Information Guide 5
Safety warnings
Safety warnings appear throughout this publication in procedures that, if performed
incorrectly, might harm you or damage the equipment. A caution or warning symbol
precedes each safety statement. The safety warnings provide safety guidelines that you
should follow when working with any equipment that connects to electrical power or
telephone wiring.
IMPORTANT
The portable (mechanical) lift tool described in “Appendix B: Field lift tool and accessory
kit” on page 135 is recommended as a safety precaution when lifting EMC components
into an EMC or customer-provided rack. As described in the appendix, many of the EMC
components are too heavy to be lifted by one person or in some cases by two persons. As
a result, this portable (mechanical) lift tool is a necessary safety requirement, especially
when lifting EMC components like the 3U, 120 and the 4U, 60 DAEs.
Overview
The EMC VNX series implements a modular architecture that integrates components for
Block, File, and Object with concurrent support for native NAS, iSCSI, Fiber Channel, and
Fibre Channel over Ethernet (FCoE) protocols. The VNX series is based on Intel Xeon-based
PCI Express 3.0 processors and delivers File (NAS) functionality via two to eight Data
Movers and Block (iSCSI, FCoE, and FC) storage via dual storage processors using a full
6-Gb/s SAS disk drive topology. The VNX Series is targeted at the entry-level to
high-end/large-capacity storage environments that require advanced features, flexibility
and configurability. The VNX Series provides significant advancements in efficiency,
simplicity, and performance.
Benefits include:
◆Support for File (CIFS and NFS), Block (FC, iSCSI & FCoE) and Object
◆Simple conversions when starting with a VNX Series Block only platform by simply
adding File services or starting with File only and adding Block services
◆Support for both block and file auto-tiering with Fully Automated Storage Tiering
(FAST) for Virtual Pools (VP - FAST VP)
◆Unified replication with RecoverPoint support for both file and block data
◆Updated unified management with Unisphere now delivering a more cohesive unified
user experience
Offering Block and File services, Block services only, or File services only, the VNX5400
platform is an entry-level storage platform. For a quick look at the VNX5400 platform
hardware features, see Table 2, “Block and File VNX5400 platform hardware feature quick
reference,” on page 9.
In a Block services configuration, the VNX5400 platform supports a 3U DPE and four types
of DAEs. The 3U DPE supported is a 25 drive 2.5-inch disk 3U enclosure (or DPE9). The
DAEs supported are a 25 drive 2.5-inch disk 2U enclosure (or DAE5S), a 15 drive 2.5- or
3.5-inch disk 3U enclosure (or DAE6S), a 120 drive 2.5-inch disk 3U enclosure (or DAE8S),

VNX5400 product description
and a 60 drive 2.5- or 3.5-inch disk 4U enclosure (or DAE7S). Expansion of up to up to
nine 2U, 25 DAEs (a maximum of 225, 2.5-inch disk drives), up to fifteen 3U, 15 DAEs (a
maximum of 225, 2.5- or 3.5-inch disk drives), up to one 3U, 120 DAE (a maximum of 120,
2.5-inch disk drives), or up three 4U, 60 DAEs (a maximum of 180, 2.5- or 3.5-inch disk
drives) is supported.
Note: When the 3U, 120 or 4U, 60 DAEs are implemented in the VNX5400 platform, the
40U Dense rack is required because of the depth of the 3U and 4U DAEs.
IMPORTANT
When calculating the number of disk drives for your Block, File, and Unified services
VNX5400 platform, the DPE is included in the total drive slot quantity of 250 drives. If the
total drive slot quantity exceeds 250, you will not be able to add another DAE. Refer to the
“Disk-array enclosures” section on page 69 for more information about the available
expansion DAEs for the VNX5400 platform.
In a File services or a Unified services configuration (Figure 1 on page 7), the VNX5400
platform supports a 3U DPE, from one to two 1U Control Stations (CS0 and CS1), one to
two 2U Data Mover enclosures having one to four Data Movers1, and four types of DAEs.
The 3U DPE supported is a 25 drive 2.5-inch disk 3U enclosure (or DPE9). The DAEs
supported are a 25 drive 2.5-inch disk 2U enclosure (or DAE5S), a 15 drive 2.5- or 3.5-inch
disk 3U enclosure (or DAE6S), a 120 drive 2.5-inch disk 3U enclosure (or DAE8S), and a
60 drive 2.5- or 3.5-inch disk 4U enclosure (or DAE7S). Expansion of up to up to nine 2U,
25 DAEs (a maximum of 225, 2.5-inch disk drives), up to fifteen 3U, 15 DAEs (a maximum
of 225, 2.5- or 3.5-inch disk drives), up to one 3U, 120 DAE (a maximum of 120, 2.5-inch
disk drives), or up three 4U, 60 DAEs (a maximum of 180, 2.5- or 3.5-inch disk drives) is
supported.
Note: The Block or the File and Unified services configuration of the VNX5400 platform can
have a mix of DAE types to conform to your specific requirements. In other words, you can
have a mix of 2U DAEs, 3U DAEs, and 4U DAEs in the same environment so as long as the
VNX5400 platform does not have no more than the supported amount of 250 disk drives.
VNX5400 product description
This section shows examples of the front and rear views of a VNX5400 platform.
Note: A fully configured VNX5400 platform with a 3U DPE of 25 (2.5-inch disk drives) can
include up to nine 2U, 25 DAEs (a maximum of 225, 2.5-inch disk drives), up to fifteen 3U,
15 DAEs (a maximum of 225, 2.5- or 3.5-inch disk drives), up to one 3U, 120 DAE (a
maximum of 120 2.5-inch disk drives), or up to three 4U, 60 DAEs (a maximum of 180,
2.5- or 3.5-inch disk drives). As a result, by using the DAEs described above in this
paragraph, the maximum disk drive capacity would become 250, 250, 145, or 205,
respectively.

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
https://mydocs.emc.com/VNX/ 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
https://mydocs.emc.com/VNX/ 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
(Figure 3 on page 15) 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 page 14 provides
more information.

14 EMC VNX5400 Hardware Information Guide
System component description
Disk drives
Each disk drive consists of one disk drive in a carrier. You can visually distinguish
between disk drive types by their different latch and handle mechanisms and by type,
capacity, and speed labels on each disk drive. You can add or remove a disk drive while
the 3U DPE is powered up, but you should exercise special care when removing modules
while they are in use. Disk drives are extremely sensitive electronic components.
IMPORTANT
When calculating the number of drives for your VNX5400 platform, the DPE is included in
the total drive slot quantity of 250 drives. If the total drive slot quantity exceeds 250, you
will not be able to add another DAE. Refer to the “Disk-array enclosures” section on
page 69 for more information about the available expansion DAEs for the VNX5400
platform.
Midplane
A midplane separates the front-facing disk drives from the rear-facing SPs. It distributes
power and signals to all components in the enclosure. SPs and disk drives plug directly
into the midplane.
Storage processor CPU
The storage process (SP) CPU is the intelligent component of the 3U disk processor
enclosure (DPE). Acting as the control center, each SP CPU includes status LEDs. The “3U,
25 (2.5-inch) disk processor enclosure” section on this page provides more information.
Storage processor dual fan pack (cooling module)
When viewed from the front, each SP CPU module has two dual fan packs located on the
bottom of the SP. Each dual fan pack includes an amber fault LED. Latches on the fan pack
lock it into place to ensure proper connection. The “Storage processor dual fan pack
(cooling module)” section on page 17 provides more information.
EMI shielding
EMI compliance requires a properly installed electromagnetic interference (EMI) shield in
front of the DPE disk 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. You must remove the bezel/shield to remove and install
the disk drives.
3U, 25 (2.5-inch) disk processor enclosure
The 25 (2.5-inch) disk processer enclosure (DPE) includes the following:
◆2.5-inch 6-Gb/s SAS or Flash disk drives (hot-swappable)
◆Status LEDs
◆CPU latches
◆Fan packs and latches
