Got questions? You’re not alone. Here are the answers to common queries about our Colocation Service, setup process and support.
A quarter rack provides you with 9U of usable space within a standard 42U data centre cabinet. This space is physically segregated and secured, giving you a private, lockable compartment that is exclusively for your equipment, offering a significant upgrade in security and control over shared colocation options.
Our quarter rack solution comes with up to 2kW of usable power as standard, delivered via resilient A+B power feeds. This generous power allocation is designed to support multiple modern servers and networking equipment. If you have higher density requirements, please speak to our team about tailored power solutions.
Yes, absolutely. Your 9U of space is a self-contained, lockable compartment within the main cabinet, accessible only by you and authorized on-site engineers. This, combined with our data centre’s multi-layered physical security and ISO 27001 certification, ensures your hardware is protected to the highest standards.
Of course. The 9U space is yours to use as you see fit. It is ideal for deploying a mix of servers, switches, firewalls, and other networking hardware. This allows you to build a small, self-contained infrastructure pod within a highly secure and resilient environment, giving you full control over your setup.
We offer a seamless upgrade path. When your business needs more space, power, or cooling, you can easily transition to a half rack, full rack, or even a multi-rack private suite. Our team will work with you to ensure a smooth migration process with minimal disruption to your services.
Yes, we provide secure, 24/7 access to your equipment should you need to perform maintenance. Our facilities are staffed by on-site engineers and protected by multi-layered security, including ID checks and access logging. Please simply provide advance notice so we can arrange for our team to grant you escorted access to your server within our data centre.
