EMC VNX8000 Disk Processor Enclosure (DPE)

EMC VNX8000 Disk Processor Enclosure (DPE)

 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. 

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

DELL EMC VNX8000 Base Knowledge.
The largest VNX server in this series. With support for a staggering 1500 drives, this system is built for large systems with a lot of storage required. The VNX8000 Unified Configuration can handle up to 4 DME with 2 to 8 DMs. Keep in mind when you have a system this large the power supplies will need to accommodate the load. That is why in the VNX8000 there are 2 Dual SPS installed when fully configured. 1 SPS is for the DPE and the other is for the DAE Disk Vault.

Form Factor: 6U | 14U
Chassis: 4U no Dives
Standby Power Supply: 2U
Max Drives: 1500
Drives Supported: SAS, NL-SAS and Flash
I/O Supported:
Support for File (CIFS and NFS), Block (FC, iSCSI & FCoE) and Object

Storage Processor:
Two CPU modules with an Intel Xeon 8-core 2.7-GHz processor facilitating Simultaneous Multi-Threading (SMT). Sixteen Double Data Rate Three (DDR3) synchronous dynamic RAM (SDRAM) slots support up to 128 GB of SDRAM per CPU module or SP using 8 GB DIMMs.
Ten PCI Gen 3, 8x lane I/O module slots (A0 – A9 and B0 – B9) and one PCI Gen 3, 16x lane I/O module slot (A10 and B10) are available for use, supporting:

• Four-port 8-Gb/s FC optical (running at 2, 4, or 8 Gb/s); labeled 8 GbE Fibre on the latch handle
• Four-port 16-Gb/s FC I/O module
• Four-port 1-Gb/s copper iSCSI I/O module
• Two-port 10-Gb/s optical or active Twinax Fibre Channel over Ethernet (FCoE) I/O module
• Two-port 10-Gb/s RJ-45 Base-T iSCSI/IP I/O module
• Two-port 10-Gb/s optical I/O module
• Four-port 6-Gb/s SAS I/O module

Standby Power Supply
The VNX8000 platform requires two dual 2U SPSs. One for the 4U SPE and one for the Vault DAE. The 2U SPS contains two 2U 2.2-kilowatt Lithium-ion batteries housed in a separate 2U tray. The SPS battery weighs approximately 28 lb (12.07 kg).

Data Movers Enclosure (DME):
On the front, the VNX8000 has from one to four DMEs having two to eight Data Movers (DMs). Each DM consists of One CPU module consisting of one Intel Xeon 6-core 2.8-GHz processor. The CPU modules in the DME contain the power, fault, and unsafe-to-remove LEDs. Six DDR3 synchronous dynamic RAM (SDRAM) slots supporting up to 24 GB per CPU module using 2 or 4 GB DIMMs.

The maximum number of I/O modules for the VNX8000 is five per DM. One FC I/O module and up to three other I/O modules.
Five PCI Gen 2, 8x lane I/O module slots (0 – 4) available for use, supporting

• Four-port 8-Gb/s optical (running at 2, 4, or 8 Gb/s); in slots A0 and B0 only;

Any combination of these I/O modules must be the same for both Data Movers.

• Four-port 1-Gb/s copper I/O module
• Two-port 10-Gb/s optical I/O module
• Two-port 10-Gb/s RJ-45 Base-T iSCSI/IP I/O module

Control Stations (CS):
The VNX8000 platform supports a 4U SPE, from one to two 1U Control Stations (CS0 and CS1)

Disk Array Enclosure (DAE)
2U, 25 (2.5-inch), the 3U, 15 (2.5- or 3.5-inch), the 3U, 120 (2.5-inch), and the 4U, 60 (2.5- or 3.5-inch) disk-array enclosures (DAEs).

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.

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
