Overview
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 2.0 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 VNX7500 is a high-end/large-capacity storage platform. It offers Block, File, or Unified
Block and File services. These services are composed of:
◆Block-only—Includes a storage processor enclosure (SPE), a 1U 1.2 KW or a 2U 2.2 KW
standby power supply (SPS), and disk-array enclosures (DAEs) for holding hard disk
drives that are integrated to facilitate Fibre Channel, Fibre Channel over Ethernet
(FCoE), and iSCSI Block services to Windows and UNIX hosts.
◆File-only—Adds the Data Mover enclosure (DME) and Control Station (CS) to SPE, SPS,
and DAEs to facilitate File services to CIFS/NFS clients.
◆Unified Block and File—Uses same hardware as the File-only 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.
The VNX7500 platform supports three types of DAEs; a 15 drive 3.5-inch disk 3U
enclosure, a 25 drive 2.5-inch disk 2U enclosure, and a 60 drive 2.5- or 3.5-inch disk 4U
enclosure. Expansion of up to fifteen 4U DAEs and one 3U DAE (a maximum of 915 disk
drives), sixty-six 3U DAEs (a maximum of 990 3.5-inch disk drives), or up to forty 2U DAEs
(a maximum of 1000 2.5-inch disk drives) is possible.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.
As an high-end/large-capacity storage platform offering Block, File, and Unified services,
the VNX7500 (Figure 1 on page 7) is one of the five models that make up the VNX series.
For a quick look at the VNX7500 platform hardware features, see Table 1, “VNX7500
hardware feature quick reference,” on page 13.
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)

Overview
EMC VNX7500 Hardware Information Guide 7
◆Unified replication with RecoverPoint support for both file and block data
◆Updated unified management with Unisphere™now delivering a more cohesive
unified user experience

– Two-port 10-Gb/s optical or active Twinax9
–Four-port1-Gb/scopper
– Two-port 1-Gb/s copper plus two-port 1 Gb/s optical
Note: The maximum number of I/O modules for the Block and File (Unified)
VNX7500 platform is five per Data Mover and any the combination of these I/O
modules must be the same for each Data Mover.
• Two management modules per Data Mover enclosure (or, one per Data Mover)
• Two power supply/cooling (fan) modules per CPU module
◆One to two Control Stations. Each Control Station consists of the following features:
• Intel 2.0 GHz single core Celeron processor
• 2 GB of RAM
• One 250-GB SATA hard drive
• Two rear-mounted USB ports and one front-mounted USB port
• Four RJ-45 10BASE-T/100BASE-TX/1000BASE-T network interface connectors
(located on the rear panel)
• Two integrated serial ports, one for laptop/console redirection and one for the
CallHome modem
• One DVD-ROM drive
◆In a Block environment, expansion of up to sixteen 4U, 60 (2.5- or 3.5-inch) disk drive
DAEs and two 3U, 15 (3.5-inch) disk drive DAEs (a maximum of 990 drives) is
supported
6. The two-port 10-Gb/s and FCoE I/O modules can also use active twinaxial (Twinax) cables. Twinax
is a type of cable similar to coax, but with two inner conductors instead of one. These cables will
be supplied in lieu of the SFP+ when so ordered.

EMC VNX7500 Hardware Information Guide 17
◆In a Block and File (Unified) environment, expansion of up to thirteen 4U, 60 (2.5- or
3.5-inch) disk drive DAEs and three 3U, 15 (3.5-inch) disk drive DAEs (a maximum of
825 drives) is supported
◆Any required cables including LAN cables, modem cables, and serial DB-9 cable.
◆Mounting rails with hardware
◆Front bezel with VNX7500 badge
System component description
This section provides a description of the Block and File (Unified) VNX7500 platform
components. The description includes illustrations and explanations of the front and rear
connectors and LED indicators.
Note: In the following sections, the illustrations and corresponding tables describe these
individual components. These descriptions are for illustrative purposes only.
VNX7500 front view
As previously described, the Block and File (Unified) VNX7500 platform is made up of a
dual 1U SPS or dual 2U SPS7, an SPE, one to four DMEs with two to eight Data Movers, and
one to two Control Stations. The following sections will describe the front (Figure 2 on
page 8) view of the Block and File (Unified) VNX7500 platform components separately.
SPE front view
The front of the Block and File (Unified) VNX7500 platform SPE contains two enclosure
status (power and fault) LEDs, as shown in Figure 6. Table 3 describes the SPE power and
fault LEDs.

7. The dual 2U SPS is used in a VNX7500 platform environment when using the 4U, 60 disk drive
DAE as a Vault drive in a 40U Dense rack.
