What’s Best for your Business? Tower, Rack or Blade?

Servers come in a range of forms – or packaging. These include tower, rack-mounted and blade, and each is suited to specific business environments depending on a range of IT and physical factors.

Tower cases are used to house the simplest servers, such as those found in leading PCs. Their rigid, upright build reflects internal limitations regarding the ability to implement extensions.

Rack servers are larger and take a rack-mounted form – a standard enclosure that is then mounted within a larger enclosure called a rack. This set-up enables a site to build a mix of server configurations that integrates power, storage and network solutions.

A natural evolution on tower and rack, blade servers are built onto a single board, with a rack-mounted enclosure able to hold many boards, each with its own processing, network and slender storage.

Below we go into more detail and examine how each package caters to different business needs and circumstances.

Tower servers

Generally employed to house lower capacity servers in an environment of limited scalability, tower servers are important to modern business.

They hold standard server components such as motherboards, CPUs, hard disks, networking and cabling, but their size means they can take up more space than rack or blade units, so they generally aren’t used in high numbers in IT server rooms. Organisations thinking of using tower servers should be able to provide adequate space, as well as the necessary cooling facilities.

Through an array of high-performance tower options, organisations can bring configuration options, scalability and performance together with huge internal storage capacity. Cutting edge towers accelerate demanding workloads and drive rapid response times while bringing expanded capacity.

Supporting up to 50 per cent more hard drives, the PowerEdge T630 brings new capabilities to SMEs and remote offices that run mail and messaging, medical imaging, server and desktop virtualisation and cost-effective graphical rendering.

The flexible storage configurations of industry-leading models allow IT staff to pinpoint workload requirements, while generous drive space enables budget-conscious in-server expansion.

Rack servers

Rack-mounted servers are a big step up holding multiple nodes that are all highly capable and flexible to configuration. Compact design lends the rack’s form to vertical arranging – space-efficiency which makes centralised server management and cabling a natural set-up.

However, the system demands heavy cooling because racks stacked with multiple servers will generate considerable heat, particularly if the entire unit is confined to a small space. Generally, firms seeking to maximise computing power while taking up as little physical space as possible will choose the rack server option.

Best rack server solutions deliver performance, availability and density through designs that can fit the needs of all business sizes. The comprehensive Dell EMC portfolio of 1-, 2- and 4-socket rack servers are engineered to minimise complexity in construction and management of data centres. PowerEdge rack servers marry unparalleled performance, functionality and reliability with superb customer value.

Blade servers

A blade server is essentially a stripped-down iteration of a typical rack-mounted server unit, and contains just the essentials: a CPU, RAM, integrated input/output (I/O) ports and network adapters.

As a package, blade is appropriate for servers that hold high numbers of limited capacity nodes. Their relatively low cost and size means these will usually build onto existing PC technology.

Constructed with a modular design to maximise energy efficiency and minimise space usage, the blade chassis provides components such as power converters, storage and cooling equipment, which all fit into a standard rack enclosure. This compact element makes it possible to arrange more units into each rack to consolidate several standard server racks into a single blade enclosure. This allows firms to optimise space and organisation in the server room, with consolidation of power along with networking cabling adding to the neatness of the set-up.

A reliable blade data centre can bring down operation costs while leveraging versatility to ensure the demands of fast-paced organisations are met. Exceptional reliability and enhanced power efficiency are hallmarks of leading models that businesses can use to secure optimised performance now and in the future.

Final thoughts

A firm’s choice of server package will largely be influenced by individual scenarios. In all cases, IT experts need to conduct a detailed assessment of business needs before identifying the right server platform.

Intelligence regarding storage capacity, processing power, available interfaces and network connections will inform the server equation you’re looking for.
