Dell Rack Servers Make a Perfect Option When Space Is Limited

The company's rack server lines supply capabilities such as improved processing speeds, energy efficiency, data protection, and critical application support. A rack model is one of three common choices a company has when wanting to deploy a server solution within a network infrastructure. As opposed to the traditional tower designs, this hardware is mountable to a slot within an enclosure. They take up less space, offer additional power, and can operate independently just as a tower design. Businesses dealing with space restrictions gain more with rack models when multiple servers are necessary. Rack-mounted designs average less than two inches in height and are best when processing or storage needs will not be changing rapidly. Suppose the hardware will be dedicated to a specific set of processes. In that case, a rack model is the best choice for a space-restricted environment since they eliminate numerous cabinets from having to be strategically placed or cabled in an area. Organizations receive increased space, less confusion, and the exact processing power needed for significant infrastructure processes.

Used Servers Offer High End Features at a Reduced Price

Cost is a significant concern when a business decides to implement a rack cabinet setup. While they may be more costly than a tower design, a business has alternative options for obtaining this hardware at a lower expense than the cost of new equipment. Used servers increase technology possibilities to smaller companies or organizations accommodating tight budgets. Reputable resellers can offer the same high equipment at an affordable rate with a dependable warranty. Any company in need of dedicated rack servers should consider refurbished or used devices to reduce expenses without compromising on needed equipment.

Various models in the PowerEdge line may be purchased as new or refurbished rack designs. PowerEdge products offer both Intel and AMD Opteron processors based around the x86 architecture. Chipsets remain consistent throughout each generation to provide familiar drivers as well as system images. Dell PowerEdge server models offer a proprietary RAID controller and provide over ten generations to choose from when purchasing server technology from this product line. Some models have since been discontinued but are purchasable as refurbished or used servers while others are still available in new condition from the retail shelf.

An organization should choose the type of server and functionality based upon exact computing needs. Rack designs allow a business to handle critical or intense applications without the need for increased hardware space. The PowerEdge R410, for example, delivers a four and eight-megabyte chipset with up to four terabytes of SATA or Near Line SAS internal storage. Features include Intel Xeon processors, sixty-four gigabytes of memory, and efficient power supply, and thermal management. It is one of the greatest choices when a company desires an energy-efficient server. Additional models such as 2650 or 6950 have been discontinued but are still purchasable through a quality reseller at a decreased cost. Dell rack servers are ideal for data centre environments and can meet the varying needs of any space confined business.

Note

I've been amassing a horde of PCs made from dumptser dive parts and have a bookshelf of hdd's. Unfortantely coordinating storage and maintaing a bunch of machines is getting out of hand. I thinking about breaking my rule and paying for hardware and getting a used server, backplane and rack but i've got no idea what the hell to look for or what a reasonable price is. Anytips on buying a used server? My goal for this machine is that it can hold or easily support a backplane with 24+ 3.5" hdds and having a gpu or igpu that can stream 4k SDR video while running a slimmed DE

hi!! first off, labgopher is a great resource for skimming ebay (though not fully comprehensive). you may have better luck setting saved searches w/notifs on ebay, if you have time to kill waiting for a good deal. oh, and uh, avoid buying gear where the pictures look like a trash heap...i once got a server wrapped in grocery bags and sticky with purple juice, crammed diagonally into an undersized box for a circular saw.

second. do not buy HP/HPE gear. (reminder, this take is not endorsed by redhat.) their shit is so outdated and crippled...the hours i sunk into finding out that a performance server (DL380p) from ~2012 had no support for UEFI boot, then setting up Duet just to get something bootable... yeah. many such cases. (after another issue someone said "oh maybe you got one with the half-broken iommu" and refused to elaborate.) pay the dell tax, or check out supermicro or whoever else, but not HP. there's a reason it's cheaper than everything else on the market, and it's that no one wants it.

so regarding the design requirements: a typical 2U LFF cage holds 12 drives. there are some machines (e.g. Dell R720xd2) that have _two_ rows of drives, which would give you the 24x capacity you're looking for, though these are gonna be pricier because of their density. the other approach would be to tack 1-2 jbod chassis onto a server. i've seen a 12xLFF 1U chassis on ebay before, with like 3 rows of drives, which was pretty neat. a chassis with all of its drives up front will take up more vertical space and probably not be much shallower than a regular server anyways.

so my ideal approach would be this:

2U server such as an R720, with plenty of room in the back for PCIe cards ($200 | $350 | $600)

a JBOD* or two, enough to meet your disk needs (remember you can also use any storage in the front of the server) ($150 | $350 | $500 each)

whatever PCIe storage controller cards and cables you need to connect the jbod to the server ($15 | $40 | $60)

a GPU that fits in your PCIe space ($??? idfk*)

*re JBOD and controllers and cables: i have not actually successfully set up a jbod of my own, or even a controller card. the only reason i got my NAS off the ground was because some madlad published a way to crossflash the H710 card that came with my servers. for this reason i am nervous to recommend too far outside what i've actually tried and accomplished

*re disks: try to get gear that comes with drive caddies, or at least uses very common caddies like dell/supermicro/netapp. i have a hitahci jbod that i found cheap on ebay...but have no idea what caddies it needs so it's kinda useless lol

*re gpu: i know next to nothing about gpus

thanks for the ask!! i think, you have inspired me to spin off another blog, since i actually do have hardware experience, as opposed to...ansible...yeah. i'll follow up when i have a new blog set up :)

Dell PowerEdge XE9680L Cools and Powers Dell AI Factory

When It Comes to Cooling and Powering Your AI Factory, Think Dell. As part of the Dell AI Factory initiative, the company is thrilled to introduce a variety of new server power and cooling capabilities.

Dell PowerEdge XE9680L Server

As part of the Dell AI Factory, they’re showcasing new server capabilities after a fantastic Dell Technologies World event. These developments, which offer a thorough, scalable, and integrated method of imaplementing AI solutions, have the potential to completely transform the way businesses use artificial intelligence.

These new capabilities, which begin with the PowerEdge XE9680L with support for NVIDIA B200 HGX 8-way NVLink GPUs (graphics processing units), promise unmatched AI performance, power management, and cooling. This offer doubles I/O throughput and supports up to 72 GPUs per rack 107 kW, pushing the envelope of what’s feasible for AI-driven operations.

Integrating AI with Your Data

In order to fully utilise AI, customers must integrate it with their data. However, how can they do this in a more sustainable way? Putting in place state-of-the-art infrastructure that is tailored to meet the demands of AI workloads as effectively as feasible is the solution. Dell PowerEdge servers and software are built with Smart Power and Cooling to assist IT operations make the most of their power and thermal budgets.

Astute Cooling

Effective power management is but one aspect of the problem. Recall that cooling ability is also essential. At the highest workloads, Dell’s rack-scale system, which consists of eight XE9680 H100 servers in a rack with an integrated rear door heat exchanged, runs at 70 kW or less, as we disclosed at Dell Technologies World 2024. In addition to ensuring that component thermal and reliability standards are satisfied, Dell innovates to reduce the amount of power required to maintain cool systems.

Together, these significant hardware advancements including taller server chassis, rack-level integrated cooling, and the growth of liquid cooling, which includes liquid-assisted air cooling, or LAAC improve heat dissipation, maximise airflow, and enable larger compute densities. An effective fan power management technology is one example of how to maximise airflow. It uses an AI-based fuzzy logic controller for closed-loop thermal management, which immediately lowers operating costs.

Constructed to Be Reliable

Dependability and the data centre are clearly at the forefront of Dell’s solution development. All thorough testing and validation procedures, which guarantee that their systems can endure the most demanding situations, are clear examples of this.

A recent study brought attention to problems with data centre overheating, highlighting how crucial reliability is to data centre operations. A Supermicro SYS‑621C-TN12R server failed in high-temperature test situations, however a Dell PowerEdge HS5620 server continued to perform an intense workload without any component warnings or failures.

Announcing AI Factory Rack-Scale Architecture on the Dell PowerEdge XE9680L
