Dual Xeon Gold 5317 compute

This 1U rack server ships with two Intel Xeon Gold 5317 processors at 3.0 GHz base and 3.6 GHz turbo, each with 12 cores. The 64 GB of DDR4 2933 MHz registered ECC memory is installed as four 16 GB modules. It targets virtualization, cloud infrastructure and dense data analytics workloads that need high core counts in a compact footprint.

Redundant 1400 W platinum power

Two hot-swap 1400 watt platinum-efficiency power supplies provide full redundancy and handle peak loads from the CPUs, ten 1.8 TB 10K SAS drives and the PERC H745 controller with 4 GB NV cache. The 1U chassis uses Dell 15G thermal design to move air front-to-back through the dense drive bay and processor area. iDRAC 9 Enterprise monitors temperatures and fan speeds remotely.

Ten-bay 2.5" front storage

The front panel holds ten 2.5 inch SAS bays populated with 1.8 TB enterprise drives connected to the PERC H745 supporting RAID 0/1/5/6/10/50/60. An OCP 3.0 slot carries a Broadcom 5720 quad-port 1 GbE network card for four copper links. Ready Rails and a front bezel are included for standard rack mounting. The system supports up to 1 TB total DDR4 memory across 16 DIMM slots and optional GPU acceleration for AI tasks.

Questions about this item

How are the 10x 2.5" SAS drives and the H745 RAID controller installed in this 1U server, and which step is commonly missed?

The 10x 1.8TB SAS drives slide into the front 2.5" hot-swap bays; the H745 controller installs in the dedicated front RAID slot. The step often missed is connecting the controller's NV cache battery and enabling the 4GB cache in the RAID BIOS before creating virtual disks.

What maintenance will the H745 RAID controller's 4GB NV cache battery require over time?

The H745 controller's 4GB NV cache includes a battery that degrades with charge cycles; it will need replacement when the iDRAC9 Enterprise or controller BIOS reports a battery health warning, typically after several years of continuous operation.

Which thermal or power limit appears first when both Xeon Gold 5317 CPUs run sustained workloads at 3.6GHz turbo?

With two 1400W Platinum PSUs and 1U airflow, the platform power budget and VRM thermal ceiling are reached before the CPUs can sustain 3.6GHz all-core turbo indefinitely; clocks will throttle to stay within the 1U thermal envelope.
