Dense 1U dual-socket server

The Dell PowerEdge R640 is a 1U rack server built for dense scale-out data centre workloads. It ships with two Intel Xeon Gold 6134 processors running at 3.2 GHz with eight cores each and 768 GB of DDR4 registered ECC memory. The platform suits virtualisation hosts, database clusters and high-performance compute nodes that need maximum throughput in a single rack unit.

Rail kit and controller cabling

The chassis includes ready rails and a front bezel for straightforward rack mounting. Hot-swap drive bays and redundant 750 W power supplies simplify field replacement without downtime. The PERC H730P controller requires its battery-backed cache module to be seated correctly; missing or loose cables are the most common reason the array does not appear at boot.

Eight 300 GB SAS drives and 3 TB memory ceiling

Eight 300 GB 10K SAS drives deliver fast local storage for operating systems, logs and scratch space; capacity runs out quickly for large data sets or backup targets. The board supports up to 3 TB across 24 DDR4 slots, so memory headroom remains generous for expanding VM density or in-memory databases.

Questions about this item

How can I verify the PERC H730P controller and all eight 300 GB SAS drives are recognised after powering on the R640?

During POST the controller BIOS will list the H730P with its 2 GB cache and show each 300 GB 10 K SAS drive; you can also open the iDRAC9 Enterprise web interface to confirm every drive appears healthy and the desired RAID level is active.

Which components are already installed and which must be purchased separately for this R640?

The server ships with two Xeon Gold 6134 processors, 768 GB DDR4 across 24 slots, the H730P controller, eight 300 GB SAS drives, the X520/I350 quad-port network card, iDRAC9 Enterprise, dual 750 W PSUs, rails and bezel; only additional drives or memory would need separate purchase.

Should I choose the 768 GB DDR4 configuration or add more memory up to the 3 TB maximum?

The 768 GB (24 × 32 GB DDR4 2666 MHz) fills every slot, so it suits workloads that fit in that capacity; if your application needs more than 768 GB you would have to replace modules with higher-capacity DDR4 to reach the 3 TB limit.
