Dual 32-core Xeon 1U storage server
The Supermicro SSG-121E-NES24R-G1 is a 1U rack system built around two Intel Xeon 6548Y+ processors. Each CPU delivers 32 cores at 2.5 GHz with 60 MB cache. The platform ships with 256 GB of DDR5-5600 ECC memory across 32 slots and supports up to 8 TB total capacity. Front hot-swap bays accept 24 E1.S NVMe drives while two internal M.2 slots add boot or cache flexibility. Dual 25 GbE SFP28 networking and dual 2000 W Titanium power supplies complete the package.
Suits dense storage workloads; not for GPU compute
This server targets organisations that need high core counts and massive local NVMe capacity in a single rack unit. The 24 front E1.S bays enable all-flash arrays for databases, software-defined storage or content delivery. Workloads requiring GPU acceleration, additional PCIe add-in cards or tower form-factor deployment will not fit this chassis. Buyers needing more than two sockets or liquid-cooling infrastructure should evaluate alternative platforms.
24 front E1.S NVMe bays define storage density
The single specification that determines fit is the 24-bay E1.S NVMe backplane. It dictates maximum drive count, drive form factor and direct PCIe connectivity to the CPUs. Confirm that your drives use the E1.S interface and that your workload can saturate the available lanes before committing to this configuration.

Questions about this item
How many front E1.S drive bays can I populate before the chassis is full?
The 1U chassis provides 24 front hot-swap E1.S NVMe bays, so the limit is 24 drives.
What is the operating temperature range the dual 2000W Titanium power supplies are rated for?
Operating temperature is specified at 10°C to 35°C (50°F to 95°F) with the eight heavy-duty 4cm fans running.
Which SFP28 modules or DAC cables do I need to use the dual 25GbE ports?
The on-board controller exposes one dual 25GbE SFP28 interface; you must supply compatible 25GbE SFP28 transceivers or direct-attach cables.
