A Dell BOSS card is a two-drive M.2 boot device, not a general-purpose RAID controller. This guide puts BOSS-S1, BOSS-S2 and BOSS-N1 side by side on media, RAID behaviour, placement and serviceability, and maps every PowerEdge model Dell documents against each card.
The Dell PowerEdge R660 has no 3.5-inch drive bays. The cost-optimized R660xs has four. This guide covers that inversion, what a single rack unit costs you in PCIe slots, GPU wattage and processor headroom, and what to check before you buy a used R660.
Dell publishes no end-of-life date for the PowerEdge R750, and the 30 November 2029 date circulating for it is Dell's date for the PowerFlex Appliance R750, not for the general-purpose server. This guide covers what that means for a used R750, how the R750, R750xs and R750xa actually differ, and the memory, processor and riser rules to check before you buy.
Dell has never published an end-of-life or end-of-support-life date for the PowerEdge R740, and has said so on the record more than once. This guide covers what that actually means for a used R740, which processors and memory are worth paying for, and what to check before you buy.
Dell still sells the PowerEdge R760 new, and sells its successor new alongside it. This guide covers what actually separates the R760, R760xs and R760xa, the memory rule that decides what you should buy, and what to check before you buy a used one.
Dell has never published an end-of-life date for the PowerEdge R640 — or for any PowerEdge server. Here is what actually governs an R640's lifecycle, how to find the only date that applies to your machine, how to configure one, and what to check before you buy a used one.
Proxmox VE 9.2 now ships an official Arm64 build, reversing a position Proxmox held as recently as 2024. Here is what actually shipped, the six limitations the announcement left out, and why almost every Proxmox buyer should still be buying x86.
How do you choose a GPU server for AI and machine learning? Work five decisions in order — workload, VRAM, single- vs multi-GPU, interconnect, and platform class — then map the result to a real NVIDIA GPU and a server you can buy, from a single low-profile L4 to a dense 8x H100 system. Plus the rent-vs-buy-vs-refurbished decision most vendor guides skip.
Which Dell PowerEdge servers support GPUs, which NVIDIA GPU fits each workload, and how to size a refurbished Dell GPU server — with the full PowerEdge x GPU compatibility matrix.
How many watts does a Dell PowerEdge R750 actually draw, and which PSU should you order? Estimated idle/typical/peak by configuration, the full factory PSU option matrix, the 120 V low-line derating that bites North American racks, FR/FTR redundancy and Hot Spare, BTU output for cooling, and a plain sizing framework.
Proxmox VE runs on almost anything, but a stable production host needs the right CPU, ECC RAM, storage controller, and network. Here is exactly what to look for — from minimum specs to a Ceph cluster — and which refurbished Dell PowerEdge servers fit each tier.
