Dense 1U dual-socket server

The Dell PowerEdge R640 packs two Intel Xeon Gold 6148 processors, each with 20 cores running at 2.4 GHz, into a single rack unit. Sixty-four gigabytes of DDR4 ECC memory and a PERC H730P RAID controller with 2 GB cache drive the storage subsystem. Dual 750 W platinum power supplies and iDRAC9 Enterprise management complete the platform.

Suited for scale-out compute and virtualization

This configuration fits dense clusters, hyper-converged nodes and database tiers that demand high core counts and hardware RAID in minimal rack space. The quad-port 1 GbE and 10 GbE SFP+ daughter card covers typical east-west traffic. Buyers who need more than 24 DIMM slots, additional drive bays beyond the eight 2.5-inch bays, or a third processor socket should evaluate other platforms.

20 cores per processor at 2.4 GHz

Each Xeon Gold 6148 delivers twenty execution threads at a 2.4 GHz base frequency with a 3.7 GHz turbo ceiling. That core density determines how many virtual machines or container instances the node can host before CPU becomes the bottleneck. Match the core count to your licensing model and workload parallelism to confirm fit.

Vragen over dit artikel

What thermal limit will the Xeon Gold 6148 hit first when all 20 cores run at 3.7 GHz turbo for hours?

The 2.4 GHz base frequency is the sustained level; turbo to 3.7 GHz is opportunistic and limited by the 1U cooling capacity and dual 750 W power budget.

How loud and hot does the R640 get with both 750 W PSUs and dual CPUs loaded 24/7?

Dual platinum 750 W supplies and high-speed 1U fans keep components within spec, but expect significant airflow noise and warm exhaust in a closed rack.

Which drive trays and caddies must I already have to populate the remaining six 2.5" bays?

The chassis uses Dell 2.5" hot-swap carriers; any SAS or SATA SSD/HDD must be mounted in those proprietary trays to connect to the H730P backplane.
