Gold Series 2U storage server
The Supermicro SSG-521E-E1CR24H-G1 is a 2U rackmount system built around a single Intel Xeon Silver 4510 processor with 12 cores at 2.40 GHz. It ships with 256 GB of DDR5 5600 ECC RDIMM memory across 16 slots and supports a maximum of 4 TB. Storage includes two 20 TB 3.5-inch SATA drives and one 960 GB M.2 NVMe SSD, while the chassis provides 24 front and top-loading hot-swap 3.5-inch bays plus two rear 2.5-inch bays and two M.2 slots. Dual 1600 W titanium power supplies and four heavy-duty 8 cm fans handle cooling and redundancy.
Suits dense capacity needs.
This server fits teams that want high raw capacity in a single 2U chassis with hardware RAID via the Broadcom 3908 controller and dual 10 GbE networking. It is not for buyers who need dual-processor scaling, GPU acceleration, or fibre-channel connectivity, because the board supports only one CPU and the supplied specification lists no PCIe add-in cards or FC ports.
Single-socket Xeon 4510 limits thread count
The installed processor is a 12-core Xeon Silver 4510 with a 30 MB cache, and the motherboard maximum is one CPU. That fixed core count is the decisive factor for licensing models tied to sockets or for workloads that demand more than 12 cores per node.

Questions about this item
How do I install the 20TB 3.5" SATA drives in the front hot-swap bays, and what step is often missed?
Slide each 3.5" SATA drive into one of the 12 front hot-swap bays until the carrier locks; the step often missed is verifying the SSD activity LED lights for every bay to confirm the backplane detected the drive.
Which components will need replacement first during long-term operation?
The four heavy-duty 8cm hot-swap fans are the primary wear items; they can be swapped individually without powering down the 2U chassis.
What thermal limit appears first under sustained full load?
The operating temperature ceiling of 35°C ambient is the first limit; exceeding it triggers the overheat UID LED and protective throttling.
