  • Intel Xeon Silver 4510 CPU powers demanding workloads
  • 16 DDR5-5600 ECC slots ensure large memory capacity
  • 24 hot-swap 3.5-inch drive bays provide massive storage
  • Two PCIe 5.0 x16 OCP 3.0 slots enable high-speed networking
  • IPMI 2.0 with KVM over LAN simplifies remote management

Intel Xeon Silver 4510 Server

The Supermicro 521E-E1CR24H-G1-OTO-66 is a new rack-mount server system built around a single Intel Xeon Silver 4510 processor. It supports up to 16 DDR5-5600 ECC memory modules in a single-socket LGA-4677 design with a thermal ceiling of 300W. The platform targets organisations that need dense, local storage capacity in a standard server form factor.

24-Bay Storage and Expansion

The chassis provides 24 hot-swap 3.5-inch bays for SAS3 or SATA3 drives plus two rear SATA slots and four optional rear NVMe slots. Two M.2 2280 sockets accept NVMe or SATA modules while a 3908 controller occupies one PCIe 5.0 slot by default. Two OCP 3.0 compliant AIOM slots and up to six PCIe 5.0 slots give flexibility for networking and accelerator cards.

IPMI Management for Remote Ops

Integrated IPMI 2.0 with KVM and media redirection over LAN lets administrators manage the server remotely without a local console. Buyers who need dual-socket compute density or GPU-heavy configurations should evaluate other platforms. Teams requiring fibre-channel connectivity or pre-installed hypervisor licences will need to source those separately.

Questions about this item

How many 3.5" drive bays will eventually need drive replacements?

The chassis holds 24 hot-swap 3.5" SAS3/SATA3 bays, so any of those 24 drives may need replacement over time.

Which component limits sustained throughput first, the PCIe 5.0 slots or the 3908 controller in slot 2?

Slot 2 is populated by the 3908 controller by default, and the six PCIe 5.0 slots share the CPU lanes, so the 3908 controller typically becomes the first bottleneck.

What is the maximum CPU heat output the cooling must handle during all-day operation?

The single LGA-4677 socket supports up to 300 W TDP, so the cooling system must dissipate that level continuously.
