Dual inline memory modules

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.

The SP assembly includes a Lithium-ion (Li-ion) internal battery that powers the associated SP assembly during a power event.

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.
