Selecting the correct server rack size is a critical decision for businesses using data centres or hosting facilities. While the question may seem simple, the answer is far from straightforward, especially if your organisation lacks detailed data centre expertise.
Fortunately, we do! If you're assessing the next steps in upgrading your server rack, follow our guide below to ensure you make the correct decision.
Unlike some industries with established standards, there is no official standard size for server racks. However, the most common size encountered is the 42U rack, designed to house 42 servers of 1 'unit' (U) each. Despite its popularity, 42U racks can vary in width and depth, with dimensions of 19 inches wide and 40 or 42 inches deep being typical. Other sizes, such as 48U racks providing additional capacity, and smaller options like 10U and 20U, are also prevalent in various use cases.
Choosing the right rack size
With the wide array of server rack sizes available, finding a reliable data centre that can cater for your needs without going overboard is crucial in getting value.
If your requirements are modest and likely to remain static, then finding a provider who can cater for half and quarter racks is ideal. Make sure there's plenty of room for your equipment and cabling.
If quick expansion is anticipated, choosing a full rack will allow for future growth with minimal disruption and re-configuration to your operations.
For larger organisations with multiple racks' of equipment, don't be put off moving data centres if you're not getting a good deal. Assess your specific priorities, considering current and future server needs, energy efficiency requirements, and cooling methods. If these requirements aren't being met in a cost-effective way, or if your current facility is out of expansion room, then shop around. There's always support. For example, ServerChoice's FlexMove® service will move your racks free of charge.
By carefully evaluating these factors, businesses can select the optimal data centre to support their unique workloads and infrastructure. Remember, there's no one-size-fits-all solution: it's about finding the perfect fit for your business's evolving needs.
