A simple buyer guide to choosing the right rack space size for UK colocation.
When to choose 1U colocation
1U colocation is best for a single rackmount server or appliance. It is useful for small production systems, backups, monitoring appliances and specialist hardware.
When to choose a quarter rack
A quarter rack gives you around 10U of dedicated rack space, which is ideal when you have several devices or want a cleaner separation than individual U space.
When to choose a full rack
A full rack gives you a dedicated 42U environment for larger server estates, storage, network infrastructure or private cloud deployments.
Plan for growth
Choose enough space for immediate needs, cabling, airflow and future expansion. It is often more cost-effective to plan a little ahead than to rework a deployment too soon.
