How to decide between half and full rack colocation

You’ve decided that colocated services are the way forward for your business. You want a reliable data centre so you don’t have to worry about building, maintaining and updating a large computing facility. These rentable data centres take care of all the extra expenses and work with the kind of security that provides peace of mind.

However, you’ll need to analyse the pros and cons when deciding whether a full or half rack is the best solution for your business. Read on to learn more about these options so you can make the most informed decision.


What is Colocation? 

Colocation can be a difficult concept to describe if you’re new to it. Simply put, the term means that servers and other IT equipment from many different companies are ‘co-located’ within one data centre. 

Also referred to as a ‘colo,’ these data centre facilities rent out rack space to third parties. It’s a simple solution designed to assist businesses that don’t have enough resources to maintain their own data centre, but still need the benefits.

Some of the benefits include lower costs, fewer members of staff, easier scalability, and the ability to choose a data centre that’s near your users. Last but not least, because the contracts you sign last at least one year, your monthly expenses are extremely predictable.


Half rack colocation

Half racks offer 20U of colocation space – a perfect solution if your needs are on the smaller end of the spectrum. At 1.75”, a rack unit (or ‘U’) measures the thickness of a single unit server.

Because of the smaller size, most half rack options are less expensive than full rack options, typically ranging between £299.00 to £479.00 per month. They also include: 

  • Power feeds of 2 to 8 amps at 240v
  • Multiple connectivity options 
  • Lockable, segregated racks for extra security

This isn’t a good solution for your business if you’re planning on growing beyond 20U, as you’d need to migrate to a larger enclosure, or contract for another. Half racks don’t give you a lot of available room to add additional equipment, but if you don’t predict on adding more equipment, this can be the most efficient and cost-effective option for your business.


Full rack colocation

If you do planning on scaling your business and adding more equipment, full racks are generally the best option. The larger size allows you to store many more servers and network equipment. 

Like half rack options, full racks are lockable cabinets for extra security. They can only be accessed by IT professionals that are approved by your business.

Because of the extra cost, you don’t want to pay for space that you don’t need, so make sure that your business actually needs this extra room. However, you may want to consider private cages or suites if you anticipate lots of growth that will soon require multiple cabinets. 

Private cages give you a little extra flexibility, such as adding desks, keyboards, monitors, additional cooling elements and more room for network equipment.


Choosing your colocation service provider

There are many providers available for colocated services, and it can be overwhelming to decide who to go with. After all, this is a long term decision that will determine the safety and upkeep of your IT equipment. 

Besides software, hardware, and cost, here are some important aspects to consider:

Security

Ensure that the provider offers both logical and physical security. Logical security is more difficult to determine than physical security, so do your research, or talk to a provider’s customer service department for clarity. You also want features such as biometric or security card access, 24×7 on-site personnel, and the ability to mitigate DDoS attacks.

Carrier options

It’s important that the data centre has various connectivity options available, including a range of blended transit and off-net, direct connection options. The best will be able to provide a wealth of options to suit any budget and requirement. 

Contracts and SLA

Part of the contract should include an SLA (Service Level Agreement) that guarantees certain levels of service, such as uptime, throughput and the mean time between failures and recovery. Ensure that you compare SLAs with the providers you’re considering, and find the one that gives you the most security.

Privacy

Make sure that the colocation service provider you’re considering has the necessary technology, policies, and procedures in place to match your regulatory compliance requirements. For instance, if your data is being transferred to another country, determine the privacy laws there and if any would be violated. 

On-Site Monitoring and Managing 

It’s important to find a provider that provides a consistent temperature-controlled environment. However, that’s not all you need to ensure your equipment is working properly. 

It’s necessary to keep track of the on-site security measures, cooling performance, power conditioning and the general operation of your equipment. You can do this yourself by travelling to the data centre on a regular basis. Another option is to determine if your provider also offers managed services. 

Moreover, environmental probes, rack monitors and power management software can help you monitor the health of your equipment even when you’re not at the location.

The My Netwise customer control panel provides most of this data to end clients as standard, meaning less of this responsibility is placed on the service user.


Colocated services for your business

As you can see, choosing a half rack versus a full rack service is all about your infrastructure needs in the moment. You also need to take into account your anticipated growth.

Geographic flexibility and the ability to travel to your colocation provider is important. It’s also recommended to shop around to find the best deals, SLAs, and features for your area.
