Dense 1U server with dual 16-core CPUs

This Dell PowerEdge R640 fits four 3.5-inch drives in a 1U rack form factor. Two Xeon Gold 6246R processors run at 3.4 GHz with 16 cores each. The system ships with 128 GB of DDR4 ECC registered memory and a PERC H740P RAID controller.

Suits virtualisation hosts needing high core

Buyers who need more than four drive bays or who require GPU acceleration should look at a larger chassis. The integrated graphics and single 10 GbE adapter limit use cases that demand discrete compute or additional network ports.

Four 3.5-inch bays set the storage ceiling

Only four large-form-factor drives can be installed, so raw capacity tops out at the sum of those four SATA devices. The PERC H740P manages RAID across them, but the bay count itself is the hard limit for local storage expansion.
