Dell PowerEdge R740 2U rack server

The Dell PowerEdge R740 is a 2U rack-mount server system built for dual-socket workloads. It ships with two Intel Xeon Gold 6148 processors, each running at 2.40 GHz with 20 cores and a 3.7 GHz turbo frequency. The system includes 64 GB of DDR4 2666 MHz registered ECC memory across four 16 GB modules. It targets organisations needing high compute density and accelerator-card support in a standard rack footprint.

Storage and networking limits

The PERC H730P controller provides 12 Gb/s SAS and SATA connectivity with 2 GB cache and battery backup, supporting RAID 0, 1, 5, 6, 10, 50 and 60 plus pass-through mode. Eight 2.5-inch drive bays accept SATA SSDs; the unit ships with two 800 GB enterprise SATA drives. Network I/O uses an Intel X520/I350 daughter card delivering two 1 GbE and two 10 Gb SFP+ ports, so 10 GbE copper is not available without an additional adapter.

Installation notes

The server includes ready rails and a front bezel for standard 4-post rack mounting. Dual 750 W platinum hot-swap power supplies require two PDU circuits for full redundancy. iDRAC 9 Enterprise enables remote firmware updates and console access before the operating system loads. Memory expansion uses 24 DDR4 slots; mixing registered ECC with unbuffered modules will prevent boot. CPU sockets are fully populated, so processor upgrades are not possible.

Questions about this item

Should I pick the dual 20-core Xeon Gold 6148 configuration or a single-processor build?

The system ships with two Xeon Gold 6148 CPUs, each 20 cores at 2.4 GHz with 3.7 GHz turbo, filling both sockets on the C620 chipset.

What does 64 GB DDR4 2666 MHz registered ECC give me in this 2U server?

Four 16 GB modules run at 2666 MHz with error correction; 20 slots remain free to reach the 3 TB maximum.

How does the PERC H730P 12 Gb/s SAS/SATA controller limit the two 800 GB SATA SSDs?

The drives connect at SATA 6 Gb/s, so the controller's 12 Gb/s SAS ceiling is not reached; RAID 0, 1, 5, 6, 10, 50, 60 and pass-through are supported.
