VNX5200
The VNX5200 is designed for the entry space. This model supports block, file, and unified configurations, and utilizes a DPE (disk processor enclosure) chassis.
The SPs in this model use a 1.2 GHz, four-core Xeon E5 processor with 16 GB of RAM, supporting a maximum of 125 drives with the following host connectivity options: FC, iSCSI, and FCoE.
This model uses a DPE that is available in a 25 x 2.5” drive form factor. The VNX Operating Environment boots from the first four drives on the DPE, known as Vault drives.
The VNX5200 DPE uses UltraFlex I/O slots for all connectivity. The first slot houses the internal network management switch, which includes a mini-serial port and service LAN port. EMC service personnel use these ports to connect to the SPs.
There is a LAN connection on each SP for array management. Each SP has five I/O module slots, and the VNX5200 supports a maximum of three I/O modules. Any slots without I/O modules populate with blanks (to ensure proper airflow).
The DPE includes two base modules, one per SP. Each base module contains a power supply, a BBU, and a SAS module containing two 6 Gb/s SAS ports for back-end connectivity to DAEs.
Figure 25 shows the back of the DPE. In this figure, you can see the various components including I/O modules and SAS modules. Figure 26 provides a close-up view of the back of the DPE.

The System Information tag (not pictured) is located on the back of the DPE, in between each SP. This tag contains serial number and part number information and should be handled carefully when racking the system.
Figure 26, Figure 27, and Figure 28 show the back of the DPE-based storage processor.

The front of the DPE houses the first bus of 25 x 2.5” drives and four fan packs, two per SP. In the middle of the enclosure, between the SPs, there is the enclosure power LED (blue) and fault LED (amber if there is a fault). Each SP has its own power LED (green), unsafe to remove LED (white hand), and fault LED (bi-color blue/amber for SP boot or fault). The drives have a power/activity LED (blue) and fault LED (amber if there is a fault), and the fan packs have an amber LED that only lights in the case of a fault. This is shown in Figure 29.

File and unified configurations use a Data Mover Enclosure (DME) with blades containing 2.13 GHz, four-core Xeon 5600 processors with 6 GB RAM per blade, with a maximum storage capacity of 256 TB per blade. The model can have one, two, or three blades, and each blade has redundant power supplies located in the front of the blade. The file and unified configurations support the following NAS protocol options: NFS, CIFS, and pNFS. The CPU module is also accessible via the front of each blade after removing the power supplies. The rear of each blade houses the slots used for internal/external network connectivity, back-end fibre connectivity, and front-end connectivity options. The DME can house two blades per 2U enclosure, and each blade can accept a maximum of two I/O modules for front-end connectivity. Figure 30, Figure 31, and Figure 32 provide pictures of the DME.
