should follow when working with any equipment that connects to electrical power or
telephone wiring.
The portable (mechanical) lift tool described in “Appendix B: Field lift tool and accessory
kit” on page 168 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
Safety warnings
The EMC VNX series implements a modular architecture that integrates hardware
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 VNX8000
platform is positioned as a high-end storage platform. For a quick look at the VNX8000
platform hardware features, see Table 2, “Block and File VNX8000 platform hardware
feature quick reference,” on page 9.
In a Block services configuration, the VNX8000 platform supports a 4U SPE (SPE9), two 2U
dual SPSs, and four types of DAEs. 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 up to sixty 2U, 25 DAEs (a maximum of 1,500 2.5-inch
disk drives), of up to one-hundred 3U, 15 DAEs (a maximum of 1,500 2.5- or 3.5-inch disk
drives), up to twelve 3U, 120 DAE (a maximum of 1,440, 2.5-inch disk drives), or up to
twenty-five 4U, 60 DAEs (a maximum of 1,500 2.5- or 3.5-inch disk drives) is supported.
Note: When the 3U, 120 and 4U, 60 DAEs are implemented in the VNX8000 platform, the
40U Dense rack is required because of the depth of the 3U, 120 and the 4U, 60 DAEs.
In a File services or a Block and File services configuration, the VNX8000 platform
supports a 4U SPE, from one to two 1U Control Stations (CS0 and CS1), two to four 2U
Data Mover enclosures having two to eight Data Movers
1
, two 2U dual SPSs, and four
types of DAEs. 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).
1. The term Data Mover is used throughout this guide. The term Data Mover is also referred to as a
blade. These terms are interchangeable and mean the same.

Note: The Block or the File and Unified services configuration of the VNX8000 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
VNX8000 platform does not have no more than the supported amount of 1,500 disk
drives.
VNX8000 product description
This section shows examples of the front and rear views of a File/Unified VNX8000
platform. These are only examples with two DMEs and a Vault DAE. A typical File/Unified
VNX8000 could be comprised of up to four DMEs and up to several DAEs.
Note: The File/Unified VNX8000 platform described in this guide includes information
about the 2U and 3U DAEs in a typical rack/cabinet environment. A File/Unified VNX8000
platform having all 4U DAEs or a mix of 2U, 3U, or 4U DAEs is typically built by
manufacturing in a Dense rack environment.

SPS battery
The SPS battery is a Lithium-ion (Li-ion) battery. The SPS battery has a handle on the front
allowing for ease of insertion and removal (Figure 4 on page 15). When installing the
Li-ion battery, you must engage it before you power on the system. Depending on how
your storage system was shipped to your site, the installation requirements for the SPS
battery will be different.
Note: The SPS battery weighs approximately 28 lb (12.07 kg).
◆If your storage system is shipped in an EMC rack by truck, the factory inserts the
battery into the SPS enclosure in the SPS tray, but does not engage it. The SPS battery
is in the parked position (wheel latch indicator yellow) inside the SPS enclosure. You
must lift the wheel latch up and push the SPS battery further into the slot of the SPS
enclosure to ensure that it is in the engaged position (wheel latch indicator green).
◆If your storage system is shipped in an EMC rack by air, the factory ships the SPS
battery separately. The battery is not installed in the cabinet or rack, and the wheel
latch indicator on the SPS enclosure is red. You must unpack the SPS battery from the
separate shipping container, install it in the SPS enclosure, and then ensure that the
SPS enclosure is engaged (wheel latch indicator green).

◆If your storage system is shipped in a shipping rack (the storage system components
will be removed and put into a customer rack), the factory inserts the battery into the
SPS enclosure in the SPS tray, but does not engage it. The SPS battery is in the parked
position (wheel latch indicator yellow). You must lift the wheel latch up and push the
SPS battery further into the slot of the SPS enclosure to ensure that it is in the
engaged position (wheel latch indicator green).

Installing the SPS battery
To install the Li-ion SPS battery:
Attach an antistatic wrist strap to your wrist and connect its cord to a known ground.
1. If the SPS battery shipped separately (SPS enclosure wheel latch indicator red),
position the battery with the LED indicator on the right and slide it into the SPS
enclosure (see location 1 in Figure 5).
2. “Park” the battery by lifting the wheel latch up on the SPS enclosure and pushing the
battery completely into the SPS enclosure slot (see location 2 in Figure 5).
The SPS battery will click into place and the wheel latch indicator will be yellow.
3. “Engage” the SPS battery by pressing the wheel latch while pushing the SPS battery
further into the SPS enclosure slot (see location 2 in Figure 5)
The SPS battery will click into the final position and the wheel latch indicator will be
green (see location 3 in Figure 5).

Storage processor (SP) AC power supply module
The storage processor enclosure (SPE) contains four power supply modules, two per
storage processor, which provide redundant power to each storage processor CPU
module, midplane, and other hardware components. A latch on the power supply locks it
into place to ensure proper connection. When viewed from the front, the SP power supply
module is located on the right side of each SP (see location 4 in Figure 6 on page 17).
Each power supply includes three status LEDs (see Detail 2 in Figure 6 on page 17).
Do not
remove the SP power supply module while the SP is plugged in. Power supply
module removal for more than a few minutes can cause the SP to shut down due to lack of
cooling.

As previously described, a Block VNX8000 platform is made up of a 4U SPE while the
File/Unified VNX8000 platform is made up of a 4U SPE, two 1U Control Stations (one

rear view of the VNX8000 platform components as previously shown in Figure 2 on
page 8.
SPS rear view
In the VNX8000 platform, a 2.2-kilowatt Lithium-ion 2U dual standby power supply (SPS)
is used to maintain power to the VNX8000 platform SPE and the Vault DAE during a power
loss.

SPS failure functionality
If AC power fails, the SPS provides backup power until the SP has flushed its write cache
data to the DAE disks. The SP then shuts off SPS power. If the cache flush has not
completed within 300 seconds—more than enough time to flush a full cache—or if the SP
has failed, then the SPS shuts down to prevent a deep discharge. If no AC input power is
available and the SPS is shut down, all the status LEDs will be off.
The output voltage, when the SPS is in the On-Line state, is a straight pass-through of the
AC voltage from inlet to outlets. When in the On-Battery state, the output voltage shall be
at an DC level within the specified limits (see the SPS battery LED in Table 11 on page 35).
When power returns, the SPS starts recharging the DC battery. It might reach a state of full

charge relatively quickly. If power remains off for a long period—days or weeks—the DC
battery might require more time to charge fully.
2
The storage processor will not use the
write cache unless it detects at least one fully charged SPS.
A faulted or not fully charged SPS disables the write caching.
The additional SPS in the dual SPS is added for redundancy. When only one SPS is used,
the AC line out connectors for the SPS provide AC voltage to both SP A and SP B.
It is important to cable each SPS so that it connects completely to either the A side or the
B side. For example, if you are looking at the SPSs from the rear, they should be
configured as:
◆SPS A (rear, right side)—Power-out and sense (management) cables connected to the
SP A power supply.
◆SPS B (rear, left side)—Power-out and sense (management) cables connected to the
SP B power supply.
Two SPSs for a Vault DAE
The additional SPS in the dual SPS is added for redundancy. When only one SPS is used,
the AC line out connectors for the SPS provide AC voltage to both LCC A and LCC B.
It is important to cable each SPS so that it connects completely to either the A side or the
B side. For example, if you are looking at the SPSs from the rear, they should be
configured as:
◆SPS A (rear, right side)—Power-out and sense (management) cables connected to the
LCC A power supply.
◆SPS B (rear, left side)—Power-out and sense (management) cables connected to the
LCC B power supply.
Note: If an SPS is cabled with the SPS sense (management) cable going to the power
supply on LCC A and the power-out cable going to the power supply on LCC B (or vice
versa), an error condition will occur when the SPS is tested or when it is charging.
2. After a full power outage, an SPS typically requires 45 minutes or a maximum of 75 minutes to
charge. To charge the SPS after being off-line usually requires at least 6 hours.

Note: When the SPS powers up, all the LEDs go through a test sequence. They will first turn on and
then turn off beginning with the SPS power on LED (green) ending with the SPS fault LED (amber).
Each LED will light for one second and then turn off. After this sequence, normal LED operation
begins. If the AC line voltage is out-of-specification at power up, no LEDs will light until the AC line
voltage is within specification.

Figure 15 shows the SPS (RJ-12 or modular jack) management port (labeled with two
symbols; one depicting a telephone handset with a line through it and the other depicting
a rectangle with a line through it). Both symbols mean that you cannot connect telephone
type circuits to this connector (see the following WARNING). This port connects the SPS (A
and B) to the SP (A and B) RJ-12 ports or to the LCC (A and B) RJ-12 ports, respectively.
The SPS (RJ-12) port is a LAN port not a WAN port. LAN ports contain safety extra-low
voltage (SELV) circuits, and WAN ports contain telephone-network voltage (TNV) circuits.
An RJ-45 (or TNV-type) looks the same as the RJ-12 except for two very important
differences. An RJ-45 is an 8-wire modular jack. The RJ-12 is a six-wire modular jack. The
RJ-45 plugs and jacks are wider than their RJ-12 counterparts - 7/16" vs 3/8". An RJ-45
plug won't fit into an R-J12 jack. But an RJ-12 plug will fit into an RJ-45 jack. Use caution
when connecting cables. To avoid electric shock, do not attempt to connect TNV circuits
to SELV circuits.

I/O modules
Several types of I/O modules are supported in the Block, File, and Unified VNX8000. The
SP supports six types of I/O modules (see “Storage processor I/O module types” on
page 47) and the Data Mover supports four types (see “Data Mover I/O module types” on
page 63). In this section, each I/O module description includes the type of port (copper or
optical) as well as a description of the LEDs.
Fibre Channel (FC) ports
The Block, File, and Unified VNX8000 platform SP does not come with built-in optical Fibre
Channel (FC) ports on the rear of each SP (A and B). As a result, the 8-Gb/s Fibre Channel
(FC) I/O module or the 16-Gb/s Fibre Channel (FC) I/O module is used to provide these FC
ports (see “Four-port 8-Gb/s FC I/O module” on page 48 and “Four-port 16-Gb/s FC I/O
module” on page 51, respectively). These ports provide an optical interface for
connecting to the front end.
EMC VNX8000 Hardware Information Guide45
Page 46
I/O modules
Small form-factor pluggable transceiver modules
The FC ports on the 8-Gb/s FC I/O module support 2-, 4-, and 8-Gb/s Fibre Channels and
on the 16-Gb/s FC I/O module supports 4, 8, and 16-Gb/s Fibre Channels using a small
form-factor pluggable plus (SFP+) transceiver module. The SFP+ transceiver modules
connect to Lucent Connector (LC) type optical fibre cables. These SFP+ transceiver
modules are input/output (I/O) devices. These SFP+ modules are hot swappable. This
means that you can install and remove an SFP+ module while the SP is operating.
Figure 33 shows an example of an SFP+ module.
Note: Besides the FC I/O modules, the FCoE and the 10-Gb/s Optical I/O modules also use
SFP modules. Each of these I/O modules use a different type of SFP. Refer to the Parts
Location Guide for more information.

Lucent Connector type interface
The Lucent Connector (LC) type interface was developed by Lucent Technologies (hence,
Lucent Connector). It uses a push-pull mechanism. LC connectors are normally held
together in a multimode duplex configuration with a plastic clip. These cables are usually
colored orange for OM2 multimode optical fiber type cables and aqua for OM3 multimode
optical fiber type cables. These cables have the duplex connectors encased in a gray
plastic covering. To determine the send or transmit (TX) and receive (RX) ferrules
(connector ends), these cables will show a letter and numeral (for example A1 and A2 for
the TX and RX, respectively) or a white and yellow rubber gasket (jacket) for the send or
transmit (TX) and receive (RX) ends (Figure 34 on page 47).
Seven I/O module types are supported by the Block, File, and Unified VNX8000 platform
SP. However, only ten slots are supported per SP (A0 – A10 and B0 – B10) in the
File/Unified VNX8000 platform SPE. For more information, refer to the
Processor I/O modules and SFPs
https://mydocs.emc.com/VNX/ and go to VNX tasks, then select Add VNX hardware. Next,
follow the steps in the wizard.
When adding new I/O modules, always install I/O modules in pairs—one module in SP A
and one module in SP B. Both SPs must have the same type of I/O modules in the same
slots.

When connecting the mini-SAS HD cable connector (plug) into the SAS I/O module ports
(sockets) 0, 1, 2, and 3, be careful of the orientation of the cable end with the port. On the
SAS I/O module, the ports have nubs (or keys). While the cable end has a notch. This
notch aligns with the nub (or key) in the port. On the other side of the cable end is a white
release tab opposite from the cable notch.
To connect, gently slide the cable into the port until you hear a small click aligning the
notch with the nub (or key) in the port. For the SAS I/O module the notch on the cable
aligns with the nub (or key) on the right side of each port. The white release tab should be
on the left side of the port.
Do Not force the cable into the port.

This section describes and illustrates the front- and rear-panel controls, ports, and LED
indicators on the disk-array enclosures (DAEs) supported on the VNX8000 platform.
DAE configuration rules:
1.) Maximum number of enclosures per bus is 10.
2.) Maximum number of drives per bus is 250.
3.) Consider the maximum number of drives supported by the storage system model.
Lifting the DAE and installing it into or removing it from a rack is a two- to three-person
job. If needed, use an appropriate lifting device (portable mechanical lift). A fully loaded
2U, 25 DAE; 3U, 15 DAE; 3U, 120 DAE; or 4U, 60 DAE weighs approximately 45 lb (20.41
kg), 68 lb (30.84 kg), 165 lb (74.8 kg), or 213 lb (96.62 kg), respectively.
Disk-array enclosures
Because the 3U, 120 and the 4U, 60 DAEs are extremely heavy, EMC recommends a
portable mechanical lift manufactured by Alum-A-Lift. For more information about the
EMC recommended portable mechanical lift and an example illustration depicting the lift,
go to “Appendix B: Field lift tool and accessory kit” on page 168.
Access to the internal components in a 3U, 120 (DAE8S) or a 4U, 60 (DAE7S) enclosures
mounted 31U (4.5 feet, or 1.38 meters) or higher above the floor requires an appropriate
lifting device (portable mechanical lift) and is restricted to authorized service personnel
only. Attempts to service disks, fans, or other DAE components mounted 31U or higher
without a portable mechanical lift and personnel may result in serious personal injury.
For more information about the weight and dimensions of a VNX8000 platform DAEs, go
to https://mydocs.emc.com/VNX/ and go to the About VNX section, and then select View
technical specifications. Next, follow the steps in the wizard.
The VNX8000 platform supports the expansion of four types of disk-array enclosures
(DAEs) across a 6-Gb/s SAS bus:
◆“2U, 25 (2.5-inch) DAE (DAE5S)” on page 77
◆“3U, 15 (3.5-inch) DAE (DAE6S)” on page 85
◆“3U, 120 (2.5-inch) DAE (DAE8S)” on page 94
◆“4U, 60 (2.5- or 3.5-inch) DAE (DAE7S)” on page 111
EMC VNX8000 Hardware Information Guide73
Page 74
Disk-array enclosures
IMPORTANT
Number of supported DAEs and disks
The number of DAEs and the disks supported by the VNX8000 platform is variable
depending on the type of DAE. Typically, the VNX8000 platform supports up to sixty 2U,
25 (2.5-inch) DAEs (for a total of 1,500, 2.5-inch disk drives), up to one-hundred 3U, 15
(2.5- or 3.5-inch) DAEs (for a total of 1,500, 2.5- or 3.5-inch disk drives), up to twelve 3U,
120 (3.5-inch) DAEs (for a total of 1,440, 2.5-inch disk drivers), or up to twenty-five 4U, 60
(2.5- or 3.5-inch) DAEs (for a total of 1,500, 2.5- or 3.5-inch disk drives).
Configurations with mixtures of 2U, 3U, and 4U DAEs are also possible dependent on the
drive slot count. However, if the 3U, 120 or the 4U, 60 DAE is used as part of your request
for a mixture of DAE types, due to the depth of the 3U, 120 and 4U, 60 DAEs, the Dense
rack is always required and the storage system is not customer installable.
Additionally, you cannot build an environment beyond the supported software and
hardware requirements for that VNX8000 platform.
the software can support. The VNX8000 platform supports up to a maximum of 1000 disk
drives.
Do not
try to add more disk drives than
General
Drive carrier
Each VNX8000 platform DAE typically consists of the following components:
◆Drive carrier
◆Disk drive
◆Midplane
◆Link control cards (LCCs)
◆Inter Connect Modules (ICMs)
◆Power supply
◆Cooling modules
◆EMI shielding
11
10
In a 2U, 25 and 3U, 15 DAE, 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 (Figure 59 on page 77 and Figure 67 on page 85).
10. The 4U, 60 disk drive DAE includes Inter Connect Modules (ICMs). “4U, 60 (2.5- or 3.5-inch) DAE
(DAE7S)” on page 111
11. The 4U, 60 disk drive DAE has separate power supplies and cooling modules (fans).

Disk-array enclosures
For more information about the drive carrier in a 3U, 120 or 4U, 60 DAE, see the “3U, 120
(2.5-inch) DAE (DAE8S)” section on page 94 and the “4U, 60 (2.5- or 3.5-inch) DAE
(DAE7S)” section on page 111.
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 DAE is powered up, but you should exercise special care when removing disk drives
while they are in use. Disk drives are extremely sensitive electronic components.
In a 2U, 25 or 3U, 15 DAE, a midplane separates the front-facing disk drives from the
rear-facing LCCs and power supply/cooling modules. It distributes power and signals to
all components in the enclosure. LCCs, power supply/cooling modules, and disk drives
plug directly into the midplane.
In a 2U, 25 or 3U, 15 DAE, an LCC supports, controls, and monitors the DAE, and is the
primary interconnect management element. Each LCC includes connectors for input and
expansion to downstream devices. An enclosure address (EA) indicator is located on each
LCC (Figure 65 on page 83 and Figure 73 on page 92)
12
. Each LCC includes a bus (loop)
identification indicator (Figure 65 on page 83 and Figure 73 on page 92).
In a 3U, 120 DAE, an LCC supports, controls, and monitors the DAE, and is the primary
interconnect management element. Each LCC includes connectors for input and
expansion to downstream devices. An enclosure address (EA) indicator is located on each
LCC (Figure 101 on page 119)
11
. Each LCC also includes a bus (loop) identification
indicator (Figure 101 on page 119).
In a 4U, 60 DAE, the primary functionality of an LCC is to be a SAS expander as well as to
provide enclosure services to all the disk drives (60 in all). In other words, the LCC in a 4U
DAE (Figure 111 on page 129) implements a version of the Common Disk Enclosure
Sub-system (CDES) architecture. CDES consists of the PMC-Sierra PM8005 SXP 6G SAS
expander, the Common Disk Enclosure FPGA (CDEF) and supporting logic.
In the 4U, 60 DAE LCC, two SAS expanders are available. As previously described, the SAS
expanders are PMC-Sierra SXP36 6G (PM8005, rev C) components. Each expander
functions or operates separately. That is, each expander has its own CDEF and supporting
logic to support 30 drives each. A 4-lane SAS wide port connecting each expander to the
Inter Connect Module (ICM) expander on the same side (A or B) of the 4U DAE is available.
Each expander manages the drives it is connected to. The only shared resources are the
LCC LED and the expander I

Disk-array enclosures
Power supply
In a 2U, 25 or 3U, 15 DAE, the power supply/cooling module integrates independent
power supply and blower cooling assemblies into a single module.
Each power supply is an auto-ranging power-factor-corrected, multi-output, off-line
converter with its own line cord. The drives and LCC have individual soft-start switches
that protect the disk drives and LCC if you install them while the disk enclosure is
powered up. A disk or blower with power-related faults will not affect the operation of any
other device.
In a 2U, 25 or 3U, 15 DAE, each power/cooling module has three status LEDs (Figure 66 on
page 84 and Figure 74 on page 93).
In a 3U, 120 DAE, the power supplies and cooling modules or fans are separated. The
power supplies are located on the rear. The power supply module has an orange knob
used for removing and installing the power supply module from the DAE (Figure 78 on
page 98). The cooling modules or fans are located in the front and in the middle of the
DAE.
In a 4U, 60 DAE, the power supplies (Figure 102 on page 120) and cooling modules
(Figure 94 on page 112) are separated and located at opposite ends of the 4U DAE. The
power supplies are located on the rear of the 4U DAE.
Cooling modules
EMI shielding
In a 2U, 25 or 3U, 15 DAE, the enclosure cooling system consists of dual-blower modules
in each power supply/cooling module.
In a 3U, 120 DAE, the cooling modules or fans are located in the front of the DAE and in
the middle of the DAE. The cooling modules or fans can only be installed/removed by
sliding the DAE forward, then sliding the DAE cover to the rear. You access the cooling
modules or fans from inside the DAE (see the “Access to disk drives and fan modules
(cooling modules)” section on page 106 for more information).
In a 4U, 60 DAE, the cooling modules or fans are separate from the power supply
modules. The cooling modules or fans are located on the front of the 4U, 60 DAE. The
cooling modules or fans can only be installed/removed by sliding the DAE forward, then
sliding the DAE cover to the rear. You access the cooling modules or fans from inside the
DAE (see the Caution on page 123 for more information).
EMI compliance requires a properly installed electromagnetic interference (EMI) shield in
front of the DAE disk drives. When installed in cabinets that include a front door, the DAE
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 drive modules.

Figure 61 Example of 2U, 25 (2.5-inch) disk drive DAE (rear view)
The 6-Gb/s SAS LCC supports, controls, and monitors the DAE, and is the primary
interconnect management element. Each LCC includes connectors for input and output to
downstream devices.
As described previously, the LCCs in a DAE connects to the SPE and other DAEs with
6-Gb/s SAS cables. The cables connect the LCCs in a system in a daisy-chain topology.
Internally, each DAE LCC connects to the drives in its enclosure in a point-to-point fashion
through a switch. The LCC independently receives and electrically terminates incoming
signals. For traffic from the system’s storage processors, the LCC switch passes the signal
from the input port to the drive being accessed; the switch then forwards the drive output
signal to the port.
EMC VNX8000 Hardware Information Guide79
Page 80
Disk-array enclosures
Note: If the target drive is not in the LCC’s enclosure, the switch passes the input signal
directly to the output port.
Each LCC independently monitors the environmental status of the entire enclosure, using
a microcomputer-controlled monitor program. The monitor communicates the status to
the storage processor, which polls disk enclosure status. LCC firmware also controls the
SAS PHYs and the disk-module status LEDs.
As shown in Figure 61 on page 79, an enclosure ID
13
indicator is located on each LCC.
Each LCC also includes a bus (back-end port) identification indicator. The SP initializes
the bus ID when the operating system is loaded.
LCC input/output ports and connectors — The 2U, 25 (2.5-inch) DAE LCC supports the
following I/O ports on the rear:
◆Two 6-Gb/s PCI Gen 2 SAS ports
◆One management (RJ-12) connector to the SPS
6-Gb/s SAS x4 ports
The DAE LCC supports two (one input and one output) 6-Gb/s SAS x4 ports (labeled
6Gb SAS 0 x4 and 0 x 1) on the rear of each LCC (A and B). This port provides an interface
for SAS and NL-SAS drives on the DAE. This port is a 26-circuit SAS small form-factor 8088
(SFF-8088) specification (socket or receptacle) using an SFF-8088 specification mini-SAS
26-circuit cable (plug) with a pull tab.
Note: Each mini-SAS cable is keyed with an in and
out
connection to prevent incorrect
cabling.
A video describing how to properly connect mini-SAS HD cables and mini-SAS cables to a
DPE and a DAE, respectively, in a VNX product is available online at:

that you cannot connect telephone type circuits to this connector (see the following
WARNING). This port connects the LCC (A and B) ports to the SPS (A and B) ports,
respectively.
The SPS (RJ-12) port is a LAN port not a WAN port. LAN ports contain safety extra-low
voltage (SELV) circuits, and WAN ports contain telephone-network voltage (TNV) circuits.
An RJ-45 (or TNV-type) looks the same as the RJ-12 except for two very important
differences. An RJ-45 is an 8-wire modular jack. The RJ-12 is a six-wire modular jack. The
RJ-45 plugs and jacks are wider than their RJ-12 counterparts - 7/16" vs 3/8". An RJ-45
plug won't fit into an R-J12 jack. But an RJ-12 plug will fit into an RJ-45 jack. Use caution
when connecting cables. To avoid electric shock, do not attempt to connect TNV circuits
to SELV circuits.

LCC
The LCC supports and controls one 6-Gb/s mini-SAS bus and monitors the DAE. A blue
link/activity LED indicates a DAE operating at 6 Gb/s.
The LCCs in a DAE connects to the SPE and other DAEs with 6-Gb/s cables. The cables
connect the LCCs in a system in a daisy-chain (loop) topology.
Internally, each DAE LCC uses protocols to emulate a loop; it connects to the drives in its
enclosure in a point-to-point fashion through a switch. The LCC independently receives
and electrically terminates incoming signals. For traffic from the system’s storage
processors, the LCC switch passes the signal from the input port to the drive being
accessed; the switch then forwards the drive output signal to the port.
Note: If the target drive is not in the LCC’s enclosure, the switch passes the input signal
directly to the output port.
Each LCC independently monitors the environmental status of the entire enclosure, using
88EMC VNX8000 Hardware Information Guide
a microcomputer-controlled monitor program. The monitor communicates the status to
the storage processor, which polls disk enclosure status. LCC firmware also controls the
SAS PHYs and the disk-module status LEDs.

As shown in Figure 69 on page 88, an enclosure ID14 indicator is located on each LCC.
Each LCC also includes a bus (back-end port) identification indicator. The SP initializes
the bus ID when the operating system is loaded.
Note: An LCC might be in either the A slot, as shown, or the B slot above it, depending on
the DAE placement within a system. For example, the front DAE in some systems is in slot
A; the rear enclosure LCC is inverted, and in slot B.

voltage (SELV) circuits, and WAN ports contain telephone-network voltage (TNV) circuits.
An RJ-45 (or TNV-type) looks the same as the RJ-12 except for two very important
differences. An RJ-45 is an 8-wire modular jack. The RJ-12 is a six-wire modular jack. The
RJ-45 plugs and jacks are wider than their RJ-12 counterparts - 7/16" vs 3/8". An RJ-45
plug won't fit into an R-J12 jack. But an RJ-12 plug will fit into an RJ-45 jack. Use caution
when connecting cables. To avoid electric shock, do not attempt to connect TNV circuits
to SELV circuits.

The cable connecting the LCC to the SPS is an RJ-12 to RJ-12. It has an RJ-12 adapter (LCC
side) on one end and a RJ-12 (SPS side) adapter on the other end (Figure 17 on page 31).
LCC enclosure ID (enclosure address) and bus ID
On the rear of the LCC (A and B), an LCC enclosure ID indicator is provided. This ID
indicator is a seven-segment LED display for displaying decimal numbers. The LCC
enclosure ID appears on both LCCs (A and B) which is the same ID number. The enclosure
ID is set at installation (Figure 73).
Each LCC includes a bus (loop) identification indicator. This indicator includes two
seven-segment LED displays for displaying decimal numbers. The SP initializes the bus ID
when the operating system is loaded (Figure 73).

IMPORTANT
Each power supply is an auto-ranging, power-factor-corrected, multi-output, offline
converter with its own line cord. Each supply supports a fully configured DAE and shares
load currents with the other supply. The drives and LCCs have individual soft-start
switches that protect the disk drives and LCCs if they are installed while the disk
enclosure is powered up.
The enclosure cooling system includes two dual-blower modules.
3U, 120 (2.5-inch) DAE (DAE8S)
In a VNX7600 platform, the 3U, 120 (2.5-inch) DAE is only supported in a Dense rack
configuration. This Dense rack is 40U or 5.1 feet (1.55 meters) high and 44 inches
(17.32 cm) deep. Each 3U, 120 DAE that goes into the Dense rack weighs 50 lb (22.6 kg)
empty and 165 lb (74.8 kg) fully loaded. As a result; whenever the 3U, 120 DAE
configuration is ordered, it is assembled and configured at the factory before shipping.
Access to the internal components in a 3U, 120 (DAE8S) enclosure mounted 31U (4.5 ft,
or 1.38 m) or higher above the floor requires an appropriate EMC service ladder and is
restricted to authorized service personnel only. Attempts to service disks, fans, or other
DAE components mounted 31U or higher without a recommended EMC service ladder and
personnel may result in serious personal injury. If an EMC service ladder is on site, this
ladder is the property of EMC and is only available for use by authorized EMC service
personnel.
If installing a new 3U, 120 DAE or replacing an existing 3U, 120 DAE above 31U is
necessary, then an appropriate portable mechanical lifting device is required. For more
information about this type of device, see “Appendix B: Field lift tool and accessory kit”
on page 168.
The 3U, 120 (2.5-inch) DAE in the VNX7600 platform is 3U (5.25 in.) high. Figure 75 on
page 95 shows an example of the front and rear views of a 3U, 120 (2.5-inch) DAE.

modules located in the mid-section of the DAE (Figure 88 on page 107). All of the fan
modules are installed or removed with the DAE pulled out of the cabinet (for information
about how to install or remove the fan module, go to “Access to disk drives and fan
modules (cooling modules)” on page 106). For a closer look of a fan module, go to “Fan
module (cooling module)” on page 109.
System status card
The system status card (SSC) is a removable circuit board located on the bottom, front of
the 3U, 120 DAE and provides the following functionality (Figure 76 on page 96):
◆Three status LEDs (Table 41 on page 97)
• SSC fault LED
•Enclosure fault LED
• Enclosure power LED
◆Fan voltage of 12 VDC is provided to two fans; fan 0 located in the front of the DAE and
fan 7 located in the mid-section of the DAE; this maintains proper cooling,
◆An inlet temperature sensor that determines the ambient temperature outside the
enclosure
◆SSC resume EEPROM for tracking manufacturing information
