Storage processor assembly internal components
Included within the SP assembly are the following components:
l
Dual inline memory modules (DIMM)
l
M.2 SSDs
l
Internal battery backup module
l
Fan module
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.
Internal battery backup module
The SP assembly includes a Lithium-ion (Li-ion) internal battery that powers the
associated SP assembly during a power event.
M.2 SSD
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.
Fan module
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 performs a protective thermal shutdown if two cooling modules fault
within the same SP assembly.
