The Dell PowerEdge T340 8-Bay 3.5" is Dell's 14th-generation entry-tier tower server, built for the small business, remote and branch office, and edge sites that need genuine server reliability without datacenter overhead. This refurbished single-socket platform pairs one Intel Xeon E-2100 or E-2200 processor with up to 64 GB of ECC DDR4 and eight 3.5" hot-plug bays in a quiet, office-friendly tower. It is the tower companion to the rack-form Dell PowerEdge R340 4-Bay 3.5" rack server, and the step below the dual-socket Dell PowerEdge T440 8-Bay tower when a single socket is genuinely enough.

We see the T340 chosen most often as a first real server: the box that retires a desktop-class machine or an aging T330, then runs file and print, a line-of-business database, Active Directory, and a local backup target on one energy-efficient socket. Where buyers get into trouble is overspecifying it. The T340 is not a virtualization-density host and it does not take a GPU. Sized to its lane, it is one of the best-built low-cost servers Dell has ever shipped, with a chassis and materials quality that punch well above the price.

To configure a build, call our team at 1-800-778-1545 and we will spec the CPU, memory, controller, and drives to your actual workload. Every T340 ships after a 12+ hour burn-in and carries our 180-day warranty, with volume pricing that starts at 5 units. We quote, we do not retail: tell us the workload and we recommend the configuration rather than selling you the most expensive line item.

Where the T340 Fits in the PowerEdge Family

The T340 sits at the top of Dell's 14th-gen single-socket entry tier. Below it, the T140 is the cabled, fixed-drive entry tower for the smallest deployments. Beside it, in rack form, the Dell PowerEdge R240 4-Bay 3.5" rack server and the R340 share the same Intel Xeon E-2100 and E-2200 platform but in a 1U chassis for buyers who already have a rack. Above it, the dual-socket T440 doubles the sockets and memory channels for light virtualization, and the Dell PowerEdge T640 8-Bay flagship tower opens the full 24-DIMM enterprise envelope. What distinguishes the T340 from its rack cousins is the tower form factor itself: it runs quietly enough to live under a desk or in a closet, with no rack required and no datacenter-grade cooling assumed.

Storage - 8 LFF 3.5" Bays

The 8-bay configuration is the maximum-capacity T340 chassis: eight 3.5" hot-plug SAS or SATA bays, supporting enterprise HDDs, SSDs, and 2.5" drives mounted in 3.5" hybrid carriers. At eight bays of high-capacity nearline SAS or SATA, the platform reaches roughly 112 TB raw with 14 TB drives, and more as drive capacities climb. That makes the 8-bay the right T340 for a file server, a backup repository, or a media and archive target where spindle count and raw capacity matter more than IOPS.

For boot, we recommend the BOSS card. The Boot Optimized Storage Subsystem puts a pair of mirrored M.2 240 GB SATA SSDs on a dedicated PCIe card with hardware RAID 1, which keeps the operating system off the front bays and frees all eight 3.5" slots for data. The alternative is to give up a front bay or two to a boot mirror, which on an 8-bay box is a waste of capacity. The platform also offers IDSDM (internal dual SD) for hypervisor boot and an internal USB option, but BOSS is the cleaner, more reliable choice for a production OS.

Storage Controllers

The T340 supports the same Dell PERC family you would recognize from the 14th-gen rack line, scaled to an entry platform:

• PERC H330: entry hardware RAID, no cache. Fine for RAID 1 boot or light read workloads where a write cache is not load-bearing.
• PERC H730P: 2 GB cache, battery-backed. This is the production storage default for the T340 when local RAID matters, especially for a small SQL or accounting database or a write-active file share. If you are buying one controller for a production box, this is the one.
• HBA330: pass-through host bus adapter, non-RAID. The right choice when a software-defined or backup-application storage layer wants raw disks rather than a hardware array.
• PERC S140: chipset software RAID. Acceptable for dev, test, and the lightest workloads only. We do not quote S140 for production data you cannot afford to rebuild from backup.

A 12 Gbps SAS HBA is available for attaching external storage. Note that the T340 will not present drives to the operating system without a controller in the path, so a controller is part of every real configuration, not an upsell.

Processors

The T340 takes one Intel Xeon E-2100 (Coffee Lake, 2018) or E-2200 (Coffee Lake Refresh, 2019) processor in a socket H4 (LGA 1151) package. The E-2200 generation is the one to buy where available: it brings up to 8 cores and a memory-speed and PCIe-lane bump over the E-2100 at the same platform. Representative SKUs we quote include the E-2288G (8 cores, 3.7 GHz base, 95W), the E-2278G (8 cores, 3.4 GHz, 80W) as the balanced workhorse, the E-2236 (6 cores, 80W), and the E-2224 (4 cores, 71W) for the lightest builds. The platform will also accept Pentium, Core i3, and Celeron entry chips, which we steer customers away from for anything beyond a fixed-function appliance.

One architectural point worth setting expectations on: this is a single-socket platform by design. There is no second socket to populate, no NUMA, and no path to more memory channels later. If the workload roadmap points toward dual-socket scaling, the right move is the T440 or T640 now rather than outgrowing the T340 in a year.

Memory

The T340 has 4 DDR4 DIMM slots fed by a 2-channel integrated memory controller, with 2 DIMMs per channel. Supported memory is ECC unbuffered (UDIMM) at up to 2666 MT/s, to a maximum of 64 GB with 16 GB modules across all four slots. This is the single hardest ceiling on the platform and the one buyers most often miss: there is no RDIMM, LRDIMM, NVDIMM-N, or Optane support here, and 64 GB is the top end, full stop.

For most T340 workloads, 32 GB to 64 GB is the right band. A file server or backup target is comfortable at 32 GB; a small database or a handful of light virtual machines wants the full 64 GB. If your sizing math is already pushing past 64 GB, that is the clearest single signal that you have outgrown the entry tier and should be looking at a platform with registered memory and more channels.

Networking and PCIe Expansion

Networking starts with an embedded dual-port 1GbE LOM (Broadcom 5720). For 10GbE or additional ports, add a PCIe network card; the T340 does not use the Network Daughter Card mezzanine found on the rack line, so any networking beyond the onboard 1GbE consumes a PCIe slot.

Expansion is four PCIe 3.0 slots, all full-height, half-length:

• One x8 electrical in an x16 connector
• One x8 electrical in an x8 connector
• One x4 electrical in an x8 connector
• One x1 electrical in an x1 connector

That slot budget is generous for a tower this size, but plan it deliberately: the BOSS card, a RAID controller, and a 10GbE NIC will each claim a slot, and the x1 slot is only useful for the lightest add-in cards.

GPU Support

The T340 does not support GPUs. The Intel Xeon E-2100 and E-2200 processors do not enable discrete graphics or compute accelerators on this Dell platform, and there is no validated GPU configuration for the chassis. This is a real constraint, not a configuration we can work around. If the workload involves any GPU compute, virtual desktop acceleration, or transcoding offload, the T340 is the wrong platform and the conversation should move to a chassis that supports accelerators.

Management - iDRAC9 Generation

The T340 carries iDRAC9 with Lifecycle Controller, the same management generation as the 14th-gen rack line. iDRAC9 Express is the practical baseline; iDRAC9 Enterprise adds full virtual console (remote KVM), virtual media, and richer automation, and is the license we recommend for any server you will manage without standing in front of it. A direct micro-USB management port on the front improves at-the-box service, and OpenManage Enterprise handles fleet management if you run more than one Dell server.

On security, the platform includes a silicon-based root of trust, cryptographically signed firmware, Secure Boot, System Lockdown, and System Erase, with an optional TPM 2.0 module for compliance frameworks. That security baseline is identical to the larger PowerEdge platforms, which is part of why the T340 is a defensible choice for a regulated small business rather than a consumer-grade alternative.

Power and Cooling

The 8-bay T340 is typically configured with dual hot-swap redundant 495W Platinum power supplies, which is the configuration we recommend for any production box where uptime matters. A single cabled 350W Bronze supply is available on the most cost-minimized builds, but it gives up redundancy. Given how often a T340 lives in an office or a closet rather than a monitored datacenter, redundant power is cheap insurance.

Thermals are not a concern on this platform the way they are on a high-TDP rack server. The top E-2288G is a 95W part, well within the tower's cooling envelope, so there are no high-performance heatsink or fan caveats to manage here.

Physical Specs and Platform Notes

• Form factor: tower, 430.3 mm tall by 218 mm wide by 603 mm deep (16.94 in by 8.58 in by 23.7 in), roughly 26 kg (57 lb) configured. A rack-conversion kit is available for buyers who later move it into a rack.
• PCIe expansion: four PCIe 3.0 slots, all full-height half-length (x8/x8/x4/x1 electrical), budgeted across BOSS, RAID controller, and any add-in NIC.
• Parts availability: mature and strong. The 14th-gen entry platform shares accessories and drives broadly across the Dell line, so spares and upgrades are easy to source. Dell ProSupport on the T340 is in its later support window in 2026, and third-party maintenance is the standard production support path at this age.
• Accessories we recommend: the BOSS card for boot, an iDRAC9 Enterprise license for remote management, a lockable front bezel for offices with foot traffic, and the optional internal optical drive only where a specific application still needs one.
• Platform notes: single-socket only with no second-socket upgrade path; 64 GB UDIMM memory ceiling; no GPU support; onboard networking is 1GbE with 10GbE requiring a PCIe card.

Our Assessment

Where it excels: The T340 is the right answer for a small business or branch office buying its first real server, or replacing a tower from the T330 era. It is excellent for file and print, Active Directory and DNS, a small SQL or accounting database, email for a modest user count, and as a local backup or Veeam repository where the eight 3.5" bays give you real capacity. The quiet tower form factor and redundant power make it genuinely deployable outside a datacenter.

Where to look instead: If you need light virtualization with room to grow, the dual-socket T440 tower is the better buy. If you already run a rack, the R340 gives you the same single-socket platform in 1U. If acquisition cost is the only thing that matters and two drives are enough, the R240 2-Bay Cabled is the floor of the 14th-gen line. And if the workload needs more than 64 GB of memory or any GPU, the entire entry tier is the wrong tier. In HPE terms, the cross-vendor counterpart to the T340 is the ProLiant ML30 Gen10.

Bottom line: Buy the T340 when one socket and 64 GB are genuinely enough and you want a quiet, well-built, serviceable tower that will run for years in an office or branch. Configure it with an E-2278G, 64 GB, a PERC H730P, a BOSS boot pair, and dual 495W supplies, and you have a dependable small-business server that costs a fraction of a rack build. The moment your sizing pushes past 64 GB of RAM, dual sockets, or a GPU, step up to the T440 instead of forcing the T340 past its design point.

Where the T340 Fits in 2026

As of 2026 the T340 is one generation behind the T350 (Intel Xeon E-2300, the 15th-gen-era entry tower) and is in the later part of its Dell support life. For the workloads this platform actually serves, that maturity is a feature rather than a risk: the hardware is proven, parts are plentiful, and the price has fallen to where a fully configured T340 is one of the best value-per-dollar servers a small business can buy. We position it honestly as a refurbished platform with several productive years ahead for its intended workloads, backed by third-party maintenance rather than active Dell warranty at this point in the lifecycle.

Honest Limitations

• 64 GB memory ceiling. Four UDIMM slots, 2666 MT/s, 64 GB maximum. There is no registered-memory path and no way past this number. Size carefully before you buy.
• Single socket, no scaling path. One processor, two memory channels. If you will need dual-socket compute, buy the T440 now rather than replacing the T340 later.
• No GPU support. The E-2100 and E-2200 processors do not enable accelerators on this platform. There is no workaround.
• 1GbE onboard only. 10GbE requires a PCIe NIC, which consumes one of the four slots you are also budgeting for BOSS and RAID.
• Entry-tier processors. Eight cores is the ceiling. Heavily threaded or consolidation workloads will saturate this CPU well before they saturate a Xeon Scalable platform.

Workload Fit

Where to Look Instead

• Need dual-socket headroom or light virtualization: the Dell PowerEdge T440 8-Bay tower is the natural step up in the same tower family.
• Want the full enterprise tower envelope: the Dell PowerEdge T640 8-Bay flagship tower opens 24 DIMM slots and dual high-core-count CPUs.
• Already have a rack: the Dell PowerEdge R340 4-Bay 1U is the same single-socket platform in rack form.
• Lowest entry cost in 14th gen: the Dell PowerEdge R240 4-Bay Hot-Swap for a budget rack build.
