Colocation FAQs

What is colocation and what are its benefits?

Colocation allows you to host servers and other IT equipment in a data centre. This is a feasible alternative to building your own, and there are many benefits to hosting your IT in a data centre:

  • Resilience and redundancies: Data centres are equipped with power, cooling, and network redundancies keeping your system online and preventing downtime.
  • Lower costs: Thanks for the efficiency of data centres, their operating costs per rack are a lot lower than in-office setups, a saving they pass onto their customers.
  • Room to grow: Getting your servers out of your office frees up more space for desks, and your data centre will handle all things infrastructure when it’s time to expand.
  • Secure: With comprehensive physical and cyber security offerings, your data is totally protected when it’s in a data centre.
  • Connectivity options: Data centres provide carrier-neutral internet connections, which guarantees speed and flexibility. You can also have your system interconnected to other data centres or connected directly to your office with a leased line.
What protection against power failures are in place?

Uninterruptible Power Supplies (UPS) are effectively large batteries that power the data centre and are constantly recharged by the mains electricity supply. This means that when there is a mains failure, the UPS is already in place to keep your servers powered, preventing downtime and potential damage from a sudden shutdown.

Additionally, data centres are equipped with generators to keep themselves powered indefinitely beyond the capacity of the UPSs.

Is colocation secure?

One of the biggest advantages of data centres is that they are totally secure and will protect your IT and your data from cyber-attacks, giving you peace of mind.

When can my engineers access my servers in colocation?

As a customer you will have 24/7 access to your servers to perform maintenance of repairs. This gives you the opportunity to schedule maintenance outside of office hours, and to repair issues with your hardware immediately, even if they appear in the middle of the night.

Can colocation services be integrated into a hybrid system?

Since data centres are equipped with powerful network infrastructure, your IT hosted in a colocation service can be connected to your other platforms, allowing you to build a hybrid system while taking advantage of colocation services.

As a provider of cloud services, 4D can offer fast and flexible Virtual Machines that can be connected into your physical hardware colocated in one of our data centres through a dedicated cross-connect.

Hybrid IT with cloud and colocation in one place has several advantages:

  • Adaptability – even if you have secure system you need to keep on private hardware, you still have scaling capacity if there’s a sudden change in demand
  • Additional security - you know exactly where your cloud solution and all of your data is located
  • Speed - a dedicated cross-connect will ensure real-time speeds between your cloud platform and collocated servers
  • Cost savings – no need for costly new network infrastructure as you don’t have to send the data from your rack over the internet to your cloud solution

Additional services

Data Centre Interconnects

Dedicated UK fibre network, Transparent, layer-2 connection

Our dedicated UK fibre network provides a transparent, layer-2 connection (with full support for 802.1q / QinQ vLANs) between any of our on-net locations.

Connections are provisioned across our core network and a backup route is provided as standard. This means that should the primary route fail due to a fibre break or equipment failure then your connection will re-route, almost instantly, through another path on our network ensuring your data can still get through.

Benefits of a data centre interconnect from 4D

  • Expand your network to new sites quickly and cost-effectively
  • Benefit from temporary connectivity between sites when migrating
  • Reduce leased line costs by connecting to a PoP close to your office
  • Save on bandwidth costs; compared to using Internet traffic and VPN tunnels
  • Connect to customers in remote locations
  • Connect to private peering partners or third-party carriers in remote locations
  • Choose from the following port speeds: 10Mbps, 100Mbps, 1Gbps, 10Gbps
  • Run your own VLAN tags with no intervention from us

Optional features

  • Setup and on-going management of switches
  • Setup and on-going management of your own dedicated firewall
  • Managed security services (access controls, VPNs, intrusion prevention and anti-virus/anti-spyware)
  • QoS (Quality of Service)
  • Separate back-up circuits with failover for resilience
  • Point-to-Multipoint

IP Transit

Full transit and partial transit, IPv4 and IPv6 supported

What you get

There are two options for IP transit; the first being ‘full transit’ and the second being ‘partial transit’:

Full transit provides you with all the routes available on the internet ensuring delivery of your IP traffic to and from every location.
Partial transit, on the other hand, includes just peering connections, which are the routes learnt from other networks that we peer with both privately and on exchanges such as Lonap or LINX.

You also get

  • IPv4 and IPv6 supported (dual stack)
  • multiple tier-1 carriers and peering exchanges
  • fully-resilient Cisco ASR based network
  • over 40 Gbps of current network capacity
  • 99.999% uptime SLA
  • and it's available in all 4D and major third party London data centres

How it works

Our IP transit services are fed directly from our Cisco ASR-based core network which has over 40 Gbps of capacity. We provide a multihomed feed of routes from Tier 1 carriers such as GTT, NTT and Telecom Italia, as well as peering routes on Lonap and LINX exchanges.

Transit is available in any of our on-net locations and is backed by our 99.999% uptime SLA.

Our network map includes a high-level representation of our core network and our connections to IP transit providers:

How much it costs

Costs are dependent on the quantity of IP transit required (in Mbps) and the location where it needs to be supplied.

Our flagship green data centre, 4D Surrey, is an award-winning data centre with a PUE of 1.14

4D Surrey has  the following green achievements
 

  • One of the greenest data centres in the UK
  • Installed one of the UK's first evaporative cooling systems
  • Award-winning green data centre project of the year
  • Cutting-edge eco-friendly cooling
  • Low actual PUE (1.14)
  • Decreased energy usage of 88.9% on current cooling load
  • Reduced carbon footprint saving c.440,605 Kg CO2 p.a.
  • Cold aisle containment
  • High intensity LED tube lighting
  • Recycling and more

About PUE

We have reduced our actual Power Usage Effectiveness (PUE) to an incredible 1.14.

PUE is calculated by dividing the total amount of power a data centre consumes by the amount used by its IT equipment. A PUE score of around 2 for a data centre is average, while 1.5 is considered efficient.

Anything below this is very difficult to achieve (which is why many data centres don't even try). Only a few other facilities are able to operate at 1.1-1.4, making 4D Surrey one of the greenest data centres in the UK.
