Dual Xeon Gold 6246R Configuration

This 1U rack server ships with two Intel Xeon Gold 6246R processors running at 3.4 GHz, each providing sixteen cores for a total of thirty-two threads. The platform targets virtualisation hosts, database clusters and compute-intensive workloads that demand high core density in a compact form factor.

Sustained Load Behaviour

The PERC H740P RAID controller manages up to four 3.5-inch SATA drives while the dual 750-watt power supplies deliver redundant power during continuous operation. Integrated iDRAC9 Enterprise enables remote monitoring and firmware updates without interrupting running services across the 384 GB DDR4 ECC memory subsystem.

Installation Notes

The chassis measures thirty-six by twenty-four by ten inches and weighs forty pounds, so plan rack space and lifting assistance accordingly. Drive caddies are not included and must be sourced separately to populate the four large-form-factor bays. Rail kits are available on request but do not ship by default.

Questions about this item

How loud and hot does the R640 get with dual Xeon Gold 6246R processors running continuously?

Two 3.4 GHz 16-core Xeon Gold 6246R CPUs draw significant power under load, so the dual 750 W supplies and internal fans will produce noticeable noise and heat in a 1U rack space; plan for proper aisle containment.

What drives and caddies do I need to populate the four 3.5-inch bays?

The chassis accepts four 3.5-inch SATA drives; the PERC H740P controller manages them, but no drives or drive carriers are included, so you must supply both.

Will my existing DDR4 ECC registered modules work with the 384 GB already installed?

The system uses DDR4 ECC registered memory; any additional modules must match that type and speed to be compatible with the populated slots.
