Dell PowerEdge R930 Server

The Dell PowerEdge R930 server is an extremely powerful enterprise server that can take on some of the most resource intensive applications. This 4U rackmount server is an absolute beast. The Dell PowerEdge R930 has only one chassis option to choose from: 24 Bay SFF.

24 Bay SFF

The 24 Bay SFF chassis for the PowerEdge R930 can accept up to twenty-four 2.5" SAS/SATA hard drives and/or solid state drives. This server supports hot-swap drives, meaning that drives can be added or removed while the system is powered on. The inside of the system has four CPU sockets that accept Intel Xeon E7-4800 v3/v4 and E7-8800 v3/v4 series processors. The R930 utilizes the Intel C602J chipset. The R930 can accept up to eight memory risers that each have 12 DIMM slots, putting the server at a total of 96 DIMM slots. In the middle of the chassis, between the memory risers and processors, are six hot-swap 120mm fans that provides cooling to the server's internals. The rear of the chassis includes a serial connector, a two USB ports, network daughter card slot, ten full-height PCIe 3.0 slots, one RAID PCIe slot, a VGA port, a dedicated iDRAC LAN port, and four hot-swap power supply bays.

The Dell PowerEdge R930 server has a max of four LGA2011-1 CPU sockets and supports Intel Xeon E7-4800 v3/v4 and E7-8800 v3/v4 series processors. A maximum of 22 CPU cores per processor is supported. This means that a total of 88 cores can be achieved.

DIMM slots & Memory Channels

The Dell PowerEdge R930 is a DDR4 based machine with 96 DIMM slots and 32 total memory channels. There are eight memory risers with 12 DIMM slots per riser. Each riser has four memory channels. Each memory channel consists of three DIMM slots.

Supported Memory Types

The PowerEdge R930 server accepts both ECC Registered (RDIMM) and Load Reduced (LRDIMM) memory. It is important to not mix memory types. Doing so can lead to unwanted issues such as boot failure.

Supported Memory Capacities

Modules capacities of 4GB, 8GB, 16GB, 32GB, 64GB, and 128GB. One thing to note is that 64GB and 128GB modules are only available as LRDIMMs. With LRDIMMs, you can achieve an overall greater RAM capacity when compared to RDIMMs.

Max Configurations

With ECC Registered, the max RAM you can achieve is 1.5TB via 48 x 32GB DDR4 modules. With Load Reduced memory, 6.1TB can be reach via a configuration of 48 x 128GB DDR4 modules.

Supported Memory Speeds

The Dell PowerEdge R930 supports module speeds of 2133MT/s and 2400MT/s. 2666MT/s modules can be installed as well, but the E5-4600v4 processor series clocks down 2666MT/s modules. The fastest speed that the installed modules can run at will be determined by the processor that is installed. If you installed a module with a speed that is higher than the maximum supported speed, that module will clock down to the max speed. For example, if your system has a max speed of 2133MT/s, and you install a 2400MT/s module, the module will clock down to 2133MT/s.

The Dell PowerEdge R930 only has support for 2.5" SAS/SATA hard drives or solid state drives. There is not LFF (3.5") chassis option for the R930. The R930's only chassis, the 24 Bay SFF, accepts up to twenty-four 2.5" SAS/SATA drives. Drive bays for the PowerEdge R930 are hot swap.

Supported Drives

Power Supplies Overview

There are a total of two power supply options for the Dell PowerEdge R930: 750W and 1100W. Power supplies for the R930 are hot swap. There are four hot-swap power supply bays on the R930's rear. It is important to make sure that all of your power supplies have the same wattage. Mixing power supplies can prevent your server from powering on.

For lower end applications, we recommend going with 750W power supply units. For more resource and power intensive applications, it is best to go with 1100W units.

The Dell PowerEdge R930 server does not accept Mini Monolithic RAID controllers. Only PCIe RAID controllers can be installed. There is a PCIe slot in the back of the server that is dedicated for the RAID card.

Unlike other systems in the 13th generation of Dell servers, the PowerEdge R930 does not have any built in LAN ports. In order to give the R930 internet access, you will need to install a Network Daughter Card (NDC) or a PCIe Network Card. Daughter cards have a spot on the motherboard that are designed only for daughter cards. We recommend going with a daughter card since it does not take up any PCIe slots. If you want additional networking capabilities in addition to a NDC, then installing an extra PCIe NIC will do the trick. There are 10GbE and fiber options for both Daughter cards and PCIe cards.
