Dell PowerEdge T440 Servers

Chassis options

The T440 shipped with either a cabled or a hot-plug backplane in two bay layouts. The bay count is fixed by the backplane and cage fitted, so choose by how many drives you need and whether you need to swap them without powering down.

All layouts take an optional BOSS card with two M.2 SATA SSDs for a mirrored boot volume, and there is space for an internal optical drive.

Processors

The T440 takes first-generation (Skylake-SP, 2017) and second-generation (Cascade Lake, 2019) Intel Xeon Scalable processors in two LGA3647 sockets, with a processor power ceiling of 105 W. That covers Bronze, Silver and the lower-power Gold 5xxx SKUs; the high-core-count Gold 6xxx and Platinum parts are not supported. Both CPUs in a system must be identical.

Silver processors cap memory at 2400 MT/s and Gold 5xxx at 2666 MT/s regardless of the DIMMs fitted. A single-CPU T440 is common and perfectly adequate for a file server or a small hypervisor; the second socket can be populated later.

Memory

Sixteen DDR4 DIMM slots, eight per processor across six channels (two channels carry two DIMMs, four carry one). Registered (RDIMM) and load-reduced (LRDIMM) modules are supported; they cannot be mixed in the same system. With one CPU installed, only the eight slots on that side are usable.

For best performance populate all six channels per CPU: 6 or 12 DIMMs in total for a dual-CPU system before filling the remaining four slots. Memory runs at the lower of the DIMM rating and the CPU limit, so 2666 MT/s modules on a Silver 4214 run at 2400 MT/s.

Storage and RAID

Drive support depends on the backplane fitted at the factory. The controller options are:

Supported drive types are 12 Gb/s SAS and 6 Gb/s SATA in both hard disk and SSD form. The T440 has no NVMe bays; a PCIe M.2 or U.2 adapter is the route to flash beyond the BOSS card. Hot-plug drives need the correct Dell 14th generation caddy; the cabled chassis uses screw-in trays.

Networking and expansion

Onboard networking is a dual-port Broadcom 5720 1 GbE LOM. Faster networking goes into one of five PCIe Gen3 slots (two x16 and three x8, full-height), which is where the tower beats its 1U sibling. Common choices:

• Intel X550-T2 dual-port 10 GbE BASE-T
• Intel X710-DA2 dual-port 10 GbE SFP+
• Broadcom 5719 quad-port 1 GbE
• A single-width GPU such as the NVIDIA T4 for inference or transcoding

Five full-height slots leave room for a PERC, a 10 GbE adapter, a tape or SAS HBA and a GPU at the same time, which is the usual reason to pick the T440 over the R440.

Power supplies

Two hot-plug redundant power supply bays, configured 1+1, with 495 W or 750 W Platinum units; entry configurations shipped with a single cabled supply. A dual-CPU system with 16 drives and a PERC sits within 750 W. Both supplies in a system should be the same rating.

Management

Every T440 includes iDRAC9 with a dedicated management port. The Express licence covers remote power, health monitoring and basic alerts; the Enterprise licence adds the virtual console, virtual media, remote firmware updates through the Lifecycle Controller and the full Redfish API, which is what most buyers actually want for a server they do not visit. Enterprise licences can be added to any unit. The T440 also supports OpenManage Enterprise for fleet management.

Physical specification

Supported operating systems

Windows Server 2016, 2019 and 2022; Red Hat Enterprise Linux 7, 8 and 9; SUSE Linux Enterprise Server 12 and 15; Ubuntu Server LTS releases; VMware ESXi 6.5, 6.7, 7.0 and 8.0; Citrix Hypervisor; and Proxmox VE, which is unsupported by Dell but widely deployed on this platform. Confirm your hypervisor's hardware compatibility list before buying if you need vendor support.

Buying a refurbished T440 from ServerDove

Every unit we sell has been through full hardware diagnostics and a burn-in run: memory tested across every installed DIMM, controller and drive health verified, both power supplies load-tested, and the management controller reset and confirmed reachable. BIOS is returned to defaults and the firmware brought to a stable release. Units carry a six-month warranty and are held in Doha, so a replacement part is a short drive away rather than a shipment from overseas. [VERIFY: same testing and warranty wording as the R640 page]

Because the T440 is now past the manufacturer's mainstream support window, we are also the practical route to keeping one in service: we stock the caddies, DIMMs, controllers, rails and power supplies it needs, and our hardware support plans cover units the manufacturer no longer will.

If you need a specific configuration that is not listed, tell us the CPU, memory and drive layout you want and we will quote a build from stock. Custom configurations are usually ready within two working days. [VERIFY: lead time]
