Is High-Density Colocation Right for Your Business?

High-density colocation is designed for businesses that own power-intensive hardware and need more power and cooling than a standard rack can provide.

    High-Density Colocation
  • Cloud Repatriation

    Bring stable workloads back from AWS or Azure for greater control, predictable monthly costs and freedom from unexpected egress charges.

  • HPC Workloads

    Support research computing, engineering simulations and render farms that need reliable high power over long periods.

  • Rack Consolidation

    Place more compute into fewer racks to reduce occupied space, simplify management and make better use of your power allocation.

  • Private Cloud

    Build dense private cloud platforms on hardware you own, with Data Centre power, connectivity and physical security around it.

  • Growing Infrastructure

    Move beyond the limits of office power and cooling without giving up control of your equipment or future expansion plans.

  • AI and GPU Infrastructure

    Run training, inference and GPU servers in racks designed to support the sustained power and cooling demands of accelerated computing.
