FAQ

What is the maximum number of processors the Dell PowerEdge R940 supports?

The Dell PowerEdge R940 supports up to 4 Intel Xeon Scalable processors (including Gold 5120, 6134, 6140, and 6226). It is a heavy enterprise-class platform designed for environments with extremely high compute demands - such as SAP HANA, Oracle RAC, and large-scale virtualisation clusters.

How much RAM can be installed in the Dell PowerEdge R940?

The Dell PowerEdge R940 supports up to 6 TB of DDR4 ECC memory. Configurations available at Hardware Direct start from 64–128 GB, and the server can be expanded to its maximum capacity without replacing the motherboard or backplane.

Is the Dell PowerEdge R940 suitable for running SAP HANA or Oracle?

Yes - the R940 is SAP HANA certified and is a common choice for Oracle RAC and SQL Server AlwaysOn deployments. Four CPU sockets, large RAM capacity, fast SSD storage in RAID, and H730P controllers deliver the IOPS levels and stability required by both OLTP and OLAP environments.

What storage drives are compatible with the Dell PowerEdge R940?

The R940 features 24 x 2.5" drive bays supporting SATA SSD, SAS, and NVMe drives (on models with a compatible backplane). This offers a wide range of configuration options: RAID 10 with fast SSDs, a hybrid setup with NVMe caching, or traditional RAID 6 for high-capacity data volumes.

Are Dell R940 servers from Hardware Direct ready to use straight out of the box?

Yes. Every R940 configuration at Hardware Direct includes iDRAC 9 Enterprise, redundant power supplies, rack rails, and SSDs pre-configured in RAID 1. On request, the server can be delivered with a pre-installed operating system, a ready-to-go RAID configuration, and an extended warranty of up to 5 years.

What workloads is the Dell PowerEdge R940 best suited for?

The R940 excels as a primary node in VMware environments with vSAN, as an analytics server (Hadoop, Spark), a database server (SQL, PostgreSQL, Oracle), and as an on-premises data centre with local storage. The large number of PCIe slots also allows for the addition of 10/25 GbE network cards, HBA controllers, GPU accelerators, or FPGAs.
