Name: Dell EMC Unity XT 680 Hybrid
SKU: 158534

Each DPE contains two SP assemblies. The SP assembly is the intelligent component providing the compute capability of the DPE. Acting as the control center, each SP assembly includes status LEDs.

Please Note: The Dell EMC Unity hybrid models are the only ones to support FAST and FAST VP technology which helps with tiered storage and accessibility to high-frequency data.

Twenty-four, 288-pin DIMM sockets support up to 12 DDR4 DIMMs, capable of up to 96 GB, 192 GB, or 384 GB of memory, depending on the model.
Each SP assembly has two slots for M.2 SSD on a M.2 SSD adaptor located between DIMM slots 5/17 and 6/18. One M.2 SSD is used for general system operations, while the other M.2 SSD is used for vaulting.
Six redundant fan modules connect to the motherboard within the SP assembly to provide continuous airflow through the front drives and through the rear of the SP assembly to keep the components at optimal operating temperatures.
The SP assembly includes a Lithium-ion (Li-ion) internal battery that powers the associated SP assembly during a power event.

I/O Modules:
Each SP has two slots that can support 5 different options.

4-port 32Gb Fibre Channel I/O module
4-port 25GbE Optical I/O module
4-port 16Gb Fibre Channel I/O module
4-port 10GbE BaseT I/O module
4-port 12Gb SAS backend I/O module

Note: 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. Please read the manual below for more details to each module listed above.
