Moving from single-server colocation to a quarter, half or full rack is a step up in operational responsibility. Power, cooling, network, cable management and physical access all become things you actively plan rather than accept as a default. Here is what to think about before your first rack-sized deployment.
1. Power budget, not just rack units
Modern servers can pull 400W to 800W under load each. A quarter rack with eight 1U dense servers can easily breach a 4 kW envelope. Sum the rated power draw of your hardware and add 20% headroom before sizing the rack. Quarter racks typically allow up to 2.5 kW, half racks up to 5 kW, full racks up to 8 kW or more. Check your contract for the exact figure.
2. Bring your own PDUs (or use ours)
Rack-sized deployments need switched, metered PDUs on both feeds. Either bring your own (Raritan, APC, Schneider) or use ours. Switched PDUs let you remote-power-cycle individual outlets, which is invaluable for headless servers.
3. Network design before you arrive
Decide before installation whether you want a top-of-rack switch with uplinks to our core, individual server uplinks, or a hybrid. Spending an extra hour on network design now saves a day of cable rework later.
4. Cable management is mandatory
A clean rack with vertical and horizontal cable managers makes everything easier: airflow, troubleshooting, future moves. Velcro ties (not zip ties), labelled cables both ends, colour-coded by function. Future-you will thank past-you.
5. Blanking panels
Every empty U in your rack needs a blanking panel. Without them, hot air recirculates from the back to the front and your inlet temperatures climb. Bring a stack with you on the install day, or buy on-site if we have them.
6. Cooling math: hot aisle / cold aisle
Your servers go in front-to-back airflow orientation, cold side facing the cold aisle. If you have any equipment that breathes side-to-side (older network gear), plan baffles or replacement. Mixing orientations breaks the cooling.
7. Approved staff list
Decide who from your company needs site access and submit photo ID and contact details for each. Pre-approved badge holders can escort their own colleagues. Removing leavers from this list is part of your own ISO 27001 obligations, not just ours.
8. Spares and consumables
Decide what spares we should hold for you on-site: replacement drives for your RAID arrays, spare SFP transceivers, patch cables. Remote hands can swap a drive within minutes if the spare is already on a shelf rather than couriered overnight.
9. Backup and monitoring
Set up monitoring (we recommend something like LibreNMS or a SaaS like Datadog) and configure alerts before you ship the hardware. You want to see the rack come up healthy on day one. For backup, add our UK Cloud Backup or Veeam Cloud Connect as the offsite copy.
10. Shipping and install day
Decide whether you ship the hardware and install yourself, or ship to us and have our engineers rack and cable it for you under remote hands. Both work. Self-install means a day on-site; remote hands install means we work to a rack diagram you send in advance.
What to budget
UK rack colocation pricing starts around £162.50 per month for a quarter rack and scales by U, kW, and add-ons. See our Quarter Rack Colocation page for the entry tier, or jump straight to Half Rack or Full Rack if your kW budget is already known.
