RAM Type: DDR4 RDIMMs, LRDIMMs
Max Ram Capacity: RDIMMs: 768GB(32GB DIMMs), LRDIMMs: 3072GB (128GB DIMMs)
Processor Socket Count: 2
Compatible Processor Series: E5-2600 v3, v4 or E5-1600 v3, v4
Number of Ram Slots: 24
Hard Drive Bays: 18 3.5" drives or 32 2.5" drives
BIOS Notes: Revision 2.1.5 adds support for E5-2600 V4 and E5-1600 V4 processors
128GB LRDIMMs Supported with V4 processors and BIOS 2.1.5 and newer.
The Dell PowerEdge T630 is a Tower based server that has the ability to be converted into a rackmount server when a mounting bracket and rails are installed. It features a proprietary Dell motherboard which is run by an Intel C612 series chipset (Desktop Similar is the X99 Chipset). This allows for dual Haswell-EP (E5-2600 v3 series) processors or Broadwell (E5-2600 v4 series) processors (If BIOS revision 2.1.5 or newer is installed) and 24 slots for DDR4 RDIMMs or LRDIMMs
When running BIOS revision 2.1.5 or newer the maximum addressable memory for a single socket configuration is 1536GB with Quad or Octo Rank Load-Reduced DIMMs. With a dual processor configuration, this figure is doubled to 3072GB. This is using 24 of the recently released 128GB LRDIMMs. If using a revision older than 2.1.5 then the maximum addressable will be 768GB in a single socket configuration or 1536GB in a dual socket configuration. This is achieved using 24 64GB LRDIMMs. Of note, you cannot utilize 128GB DIMMs until the BIOS is updated and you may not use the memory slots assigned to a non-populated processor. To explain further, you cannot achieve the 768GB single processor maximum by using 24 32GB DIMMs because 12 of the slots are associated with the empty processor socket. The memory can operate at 2400MT/s in all configurations and ranks except for triple channel configurations. With RDIMMs the maximum then becomes 1866MT/s in triple channel and LRDIMMs can still operate at 2133MT/s in triple channel
There are many storage configurations for the Dell PowerEdge T630. One option is 32 2.5" drives without the flexbay or 18 2.5" with the flexbay. Another option is 18 3.5" drives without the flexbay or 8 with the flexbay. The flexbay is essentially a riser card that allows the install of PCIe SSD cards in the front or additional hard drives or solid state drives.
There are a few known issues with the T630 that have been addressed with BIOS updates. The most major being users experiencing the red screen of death (RSOD) when using the E5-2603 or E5-2609 processors and performing a reboot. This was remedied in BIOS revision 2.1.5 so if you are using this configuration it is highly recommended you upgrade.
