Dual-socket 1U server for dense compute

The Dell PowerEdge R640 packs two Intel Xeon Gold 6142 processors at 2.6 GHz with 16 cores each into a single rack unit. With 768 GB of DDR4 2666 MHz registered ECC memory across 24 slots it targets virtualization, database and HPC workloads that need high core counts in minimal space. The PERC H730P controller supports RAID 0, 1, 5, 6, 10, 50 and 60 with a 2 GB cache battery. Quad-port networking adds two 1 GbE and two 10 Gb SFP+ links for flexible fabric connectivity.

Verify rack depth power

Confirm your cabinet can accommodate a 1U chassis with redundant 750 W platinum power supplies and front-accessible 2.5 inch SAS/SATA trays. The system ships with eight empty trays so you must supply matching drives; no SSDs or HDDs are installed. Network uplinks use SFP+ transceivers that you will need to source separately for 10 Gb links. iDRAC9 Enterprise requires a dedicated management network port and licence for full remote console and lifecycle features.

Sustained load runs on dual 750 W platinum units

Under continuous multi-threaded work both Xeon Gold 6142 CPUs can boost to 3.7 GHz while the redundant power supplies share load for efficiency and failover. The H730P battery-backed cache protects write throughput during extended RAID rebuilds or heavy transaction logs. iDRAC9 telemetry lets operators track thermal trends and power draw over hours or days without host OS involvement. Memory errors are corrected in-line by registered ECC DIMMs preventing silent corruption during long-running jobs.

Questions about this item

Does the server ship with any 2.5" drives or do I need to supply my own?

The unit includes eight 2.5" SAS/SATA drive trays but no hard disk drives are installed; you must add your own SATA or SAS drives.

Is the installed 768 GB DDR4 at the 3 TB maximum or can I add more later?

768 GB is fitted across 24 slots using 32 GB modules; the board supports up to 3 TB so additional DDR4 registered ECC memory can be added.

What RAID levels can the PERC H730P 2 GB controller handle for the drives I install?

The controller supports RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode for the SAS/SATA drives you populate.
