The 6 most important questions to ask about data centre services

Is colocation the right strategy for your business? Is it about time you moved your data to the cloud? Or maybe you’d like to move from one colocation provider to another? How do you know if a data centre service is the right choice for you? Technically, they all look the same, right?

Choosing the best data centre services provider is one of the most crucial decisions you may ever have to make for your business. Which begs the question, how do you find the best one? Well, to answer that question, you need to ask the data centre management team several questions during the vetting process.

Exceptional security is non-negotiable. You are entrusting the data centre service provider with valuable data and IT assets you cannot afford to lose. Don’t proceed unless you have suitable answers to these questions.

In this post, we are going to address six of the most critical questions you should ask.

1. What are your cooling, carrier, and power redundancies?

Power redundancy is vital when it comes to keeping a data centre up and running. Ask the data centre service provider about their power sources, where they’re fed from, how many commercial feeds they have; and most importantly, the redundancy of their UPSs. Data centre services need ample power not only to run client hardware, but also to cool the facility.

They must operate multiple backup generators to ensure availability at all times. Enquire about their connectivity options, which should also offer full redundancy of delivery to client deployments.

2. What level of protection do you have against natural disasters?

Regardless of the facility’s geographical location, there are always chances of natural disasters. Even if he facility survives a disaster, how long would the on-site generators continue to supply power?

Do they have emergency fuel suppliers? Understanding their contingency plans based on possible risks is vital. Knowing how they will inform you of the status of your systems following such disasters will help you decide if they are the facility operator of choice.

3. What level of uptime does their SLA provide?

When vetting data centre services, one of the most crucial questions you could possibly ask is how much downtime they expect to suffer. It could be devastating to lose access to your critical systems due to data centre downtime.

This could cost your business revenue, opportunities, and maybe even diminish your brands reputation. This is something you cannot afford. You’ll find 99.99% uptime SLAs in most data centres.

4. What security measures do you have in place?

Data centres nowadays feature top-of-the-line security features and access policies that protect the precious data entrusted to them by multiple businesses. Good security will always start at the perimeter, with the fencing and sensor surveillance, through to the data floors.

Aside from the layers of physical security they may offer, a data centre service needs to have logical security protocols in place that will restrict different people from accessing different areas. Companies with multi-factor authentication processes, such as biometric technology, work better in terms of protecting critical assets. They ensure only authorised personnel access certain areas of the facility.

5. Can the facility handle future growth?

Your business may have simple needs such as space, connectivity, and power at the moment, but what about your future requirements? You may need certain managed services, including cloud computing, replication, backup and archiving, managed SAN services, disaster recovery-as-a-service, among others.

Will the facility offer you such services? What about future power and space requirements?

Specify how much power you’ll be consuming and ensure they have room for more. You may be surprised later on to learn that you are limited to a certain circuit capacity, which may not be enough. Avoid placing your business in a position where you’ll need to start looking for another data centre once you experience growth.

6. How many data centres do you have and what are their locations?

This seems like a basic question, but it’s imperative. You see, you need to have a data centre that’s close enough for your frequent travels. Your technological requirements may need you to travel to the centre for maintenance, hardware and software upgrades, and server installations. A data centre close-by will certainly save you time and inconvenience.

It helps if the data centre operator has a national footprint, with facilities strategically located in different areas in case you need to branch your business. Having various centres in different locations is an assurance of redundancy. In the case of a natural disaster, you will be able to replicate your critical systems.

Bonus question: how do you handle temperature control?

Cooling innovations are important in data centres, more so as cabinet deployments increase. Enquire if the company uses cold and hot aisle containment, or whether they defuse hot air with cold. How do they manage the temperature in the facility? Do they have advanced predictive analytics and monitoring? Can they handle special cooling when the need arises?

Choose a professional data centre services company

With so many data centre options available, you may have an abundance of operators on your shortlist. However, you have to be careful about who you entrust your critical systems to. Besides all of these questions, ask about their transparency, staff qualifications, certifications, and attestations.

How often do they perform power switching tests for load performance? Do they provide 24x7x365 remote hands support? Answers to these questions will help you arrive at the right data centre service operator.

The biggest business benefits of colocation

An emerging cost effective solution for businesses large or small when it comes to their investment in infrastructure, explore the benefits of colocation.

Colocation is a hosting option that businesses all over the world use for a variety of reasons. A data centre facility generally provides colocation services, along with other related services. Data centre facilities let companies rent space for their servers and computing hardware.

Such data centres, also referred to as ‘colo data centres’, will provide the secure rack space and resilient power. They also provide connectivity / transit, cooling, and physical security for the hardware. The customer generally provides their own servers and storage.

Depending on the colocation service you choose, you can upgrade these services on the fly. Premium colocation services also offer 24×7 technical support. You can enjoy access to teams of experts that can assist your business; you can also get remote hands that can handle physical technical issues. 

So, what are the benefits of using a colocation service?

Capital expenditures

There are many reasons to use colocation services instead of building an on-site data centre space. One of the main benefits is the avoidance of huge capital expenditures (CAPEX). The CAPEX associated with creating, maintaining, and updating large computing facilities is significant. 

Relying on a colo data centre allows your business to cut these costs, moving them instead to a more manageable OPEX cost. At the same time, you get to keep ownership and complete control of your physical servers, something not offered through the use of cloud and virtual services.

The only thing to note when it comes to spending is upfront expenses. Using a colocation service still requires your business to shoulder the upfront costs of buying your own hardware. You will also typically need to shoulder the travel costs of your engineers whenever they need to access the hardware manually.

Reliable connectivity

When running a business that relies on connectivity for many core processes, uptime is absolutely critical. With a colocation service, you can enjoy 100% uptime. Constant and reliable connectivity is a significant feature colocation providers supply. 

They have superior and fully redundant high-capacity network connections. These allow colo data centres to make sure that your equipment is connected to the rest of the world 24×7. 

Furthermore, colo service providers focus considerable time and effort on proactive maintenance. This means that everything is kept running smoothly, avoiding issues that could cause downtime.

Green energy

Data centres use a considerable amount of energy. Some data centres now elect to operate in places where inexpensive green energy is available. Sometimes, it’s a product of corporate social responsibility, and other times, it’s financially practical. 

Either way, you can expect many top-tier colo providers to employ the use of green energy. We’re a good example of this, having been named one of the Best Green Business winners in the recent past.

Your company could already be green. Or, you could be looking into ‘going green’. Either way, using a colocation service instead of running a local data centre or comms room will help you achieve far greater sustainability.

Fire protection

Office buildings are generally fire protected as standard, so you may feel that this is not a feature that you specifically need. But did you know that servers need specialised fire protection?

Servers draw a lot of power. On top of that, they’re easily damaged by water. Colocation centres can handle the specific protection needs of servers and associated equipment. These include both passive and active fire protection systems. 

Passive elements include sensitive smoke detectors and VESDA systems. These are particular types of smoke detection units tuned to detect smouldering electrical components, which can identify an issue before ignition. Such methods make your servers’ fire protection to be more vigilant.

Data centres also have more passive elements like walls to prevent fires from spreading. Active elements include fire suppression systems like electrical-safe sprinklers and inert gas fire suppression.

Temperature management

Servers have to be kept at cooler temperatures than the average office space, so your employees and your servers won’t make for great office mates.

You might be willing to invest in the creation of a separate space and a cooling system in this new location, but such an endeavour can prove expensive.

Using a colocation service can help solve this issue. Colocation providers are able to watch the temperature in the data halls at multiple points, allowing them to use their robust ventilation systems to deploy climate-controlled air.

Components are kept at their optimal temperatures in this way. Other colocation providers go as far as placing their data centres in places with naturally cold climates, which offsets any additional risks in temperature rises.

Note that humidity can also affect the operation of these components. Colo data centres watch the humidity levels around your components for this very reason. This way, their humidification systems prevent static electricity build up and discharge.

Cloud migration

Cloud migration is a trend in companies of every size today. If you’re also looking to make the move to cloud computing for your business, colocation can pave the way. Colocation provides the tools you need for a smooth transition and an excellent base to build a robust hybrid system.

It allows you to move your hardware to a facility with more capacity to manage the necessary changes, meaning it can add much-needed support to the process, making it both easier and faster.

Making room to grow

The current size of your business is not likely the size it will remain forever. As you grow, your infrastructure will have to grow with you. Colocation services allow you to expand your infrastructure in-line with your growth. 

You don’t have to take on more capital expenditure. This means you will be able to expand your critical IT infrastructure, and provide support for it more quickly. You’ll also be able to do it with much less investment than you would with an on-site data centre or comms room.

Colocation solutions

When your business owns its networking equipment, servers, and storage, it’s tempting to host it all on-site. After all, it might seem like a waste to have all the equipment and have to pay someone else to host it. But you should keep in mind that office spaces are designed to meet the needs of people, not critical IT equipment.

Servers and related hardware has its own needs. These needs are specialised and highly technical. For each group – either servers or people – their needs have to be met for them to be optimally productive.

Considering a colocation service may be the best choice you could make for your business to address all these needs

Rebranding to Netwise

As we head towards our 10th birthday this December, we’ve drastically changed the way we look, both to celebrate 10 years in business, and also to reimagine our brand for the next 10 years of doing what we love.

It’s fair to say that over the last 10 years, we’ve changed a lot. The earliest iteration of what would eventually become Netwise actually started life way back in 2005, in the loft of Matthew’s parents’ house, which had been converted to house a small collection of IBM tower servers. Over the next few years, this would lead into the beginnings of Netwise Hosting, which incorporated in 2009.

The early days, while always coloured with the build and ownership of private infrastructure, focused on almost entirely on enterprise dedicated servers, with a side-focus on small-scale per unit colocation for clients with their own hardware.

As the business quickly developed, and the move to building the company’s first private data centre came to the fore in 2011, Netwise would very rapidly move into the colocation space more completely.

Netwise is now a fully-featured turnkey colocation and connectivity specialist, operating from its flagship 11,000sq ft London Central data centre in Bermondsey – the second private facility built in-house by the Netwise team.

Our bold new look

Dropping the ‘hosting’ portion of our name is only the headline change here. Beyond this, the entire look and feel of our brand has been completely reimagined.

We’ve always been known for our signature orange, which we had front-and-centre for many years early on. This did then become more of an accent colour as we moved from London South to London Central, however it always formed a prominent part of our identity. Our longest-standing customers will likely remember our (extremely) orange data hall floor at the London South data centre!

The orange has now been muted slightly, and serves as the primary accent colour to our new headline shade, which is a purple-tinted grey.

This far better embodies the characteristics we’re known for, more now than ever before. These include quality, security, robustness and professionalism – with an injection of real personality, something our customers hold very dear to their relationships with us.

The design, both of the bold new corporate identity and exciting new website, comes courtesy of leading design studio Juice London. This process started many months ago, with plenty of on-site meetings here at the Netwise HQ to discuss the visual direction, delving deep into what Netwise is at its core, and how best to represent this publicly as we grow.

Juice also spent a huge amount of time completely rethinking the website, both for desktop and mobile users, with a deep-dive into UX and UI, giving users the cleanest possible experience when interacting with us online.

Visitors to the new site will also see that, as part of the new look, we’re now running almost exclusively with black and white photography (sometimes with a purple-grey overlay), which gives our facility a timeless robustness befitting of our current standing in the industry.

The new look is head and shoulders above our legacy design, and something that will serve us very well as we head into our second decade of doing what we enjoy most.

Let’s get technical

Let’s talk about the new website; a slightly deeper chat than normal, as we’re sure our more technical readers will appreciate the added information.

This was a ground-up rebuild, starting from scratch, using the Bootstrap (4) framework as a starting point, which gives the out-of-the-box responsive front-end goodness we needed for a speedy deployment. This, coupled with the comprehensive design plans we received from Juice London, allowed for the front-end to be built out very quickly.

The main front-end came together nicely across a two to three week period, running on the new domain which sat completely separate from the existing domain. This allowed us to quickly sketch out design adjustments and alterations for immediate testing, with our Git and auto-deployment working seamlessly in this test environment.

Once we had the front-end together, but lacking some of the more complex functionality required for the colocation calculator and status pages, we were able to bring our long-time collaborator and development wizard Josh, owner of software house Grizzlyware, in-house for a week of pre-deployment works.

Grizzlyware proved to be an invaluable partner in developing our new colocation calculator, which has again been built from the ground up, giving much improved functionality, accuracy, and intrinsic security.

For the final stages of development, we converted the site from a PHP-based, dynamic, server-side site to a completely flat, minified static site, built using Node.js / NPM and deployed in both staging and production versions. This has made the new site extremely fast to load, and relies less on server-side processing in delivering content to end users.

This also bolsters the security of our digital assets, given that the site is now built ahead of being pushed to production, without need for any intensive server-side processing ahead of content delivery.

Our future as Netwise

The future as Netwise looks as bright as ever, which matches our shiny new brand perfectly!

We’re entering into a period of rapid development and expansion; as we head into 2020, we’ll be firming up plans for our next major step, which will involve a second private, bespoke data centre.

To keep abreast of these developments as they happen, keep an eye on our new latest news section, which forms part of our new website.

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.

Now that you know which option is best for your business, contact Netwise today. As one of the UK’s leading colocation service providers, we offer state of the art, highly resilient private facilities

A look back at 2018

Better late than never! Here’s our look back at 2018, yet another extremely successful and pivotal year in our history.

Investment in our operational capabilities continued full-force in 2018, with many areas seeing notable spending to improve and expand what we are able to deliver to end-users.

We’ve also helped a myriad of exciting new (and existing) customers with their own expansions, empowered by their mission-critical deployments inside of our world-class facilities.

Key projects and events for the year include:

  • Network Upgrades – we upgraded our outward-facing transit pathways, taking us to over 50Gbps of available capacity. We also upgraded our Aggregation and Core switching layers.
  • Cooling System Developments – we onlined our newest evaporative cooling stacks in line with growing demand, as well as installing a new temperature and humidity matrix, and improving the integration of our supplementary A/C systems.
  • Improved Filtration – a full overhaul of our intake filtration methodology came into effect in 2018, switching to bag filters on all three intake filter bays in Data Hall 1, increasing inward airflow and bettering the air quality inside our cold corridor.
  • Growing into Pod 3 – we welcomed a wide range of new customers into Pod 3, the newest addition to Data Hall 1.
  • Bolstered Security – with an additional 5x external PTZ cameras, along with increased on-site security personnel.
  • Further Monitoring – we’ve added a range of new monitor end-points to our network-wide system, taking us to nearly 17,000 alerting metrics across the board.
  • Growth in Connectivity – a range of exciting connectivity-focused projects in 2018 dramatically grew our service set in that area, helping a number of major organisations better connect with their customers and the wider world.
  • TV Capabilities – we added the ability to connect direct-from-air TV services from UK broadcasters straight into client racks.
  • Plus Additional Projects – countless smaller projects throughout the year.

Beyond all of this, we’ve also exceeded our financial targets for the year, taking us to new ground in terms of what we’ll be capable of delivering to end-users in 2019.

We’re excited to say that the deployment of Pods 4 & 5 in Data Hall 1 are now firmly on the horizon, with final fit-out and readiness for client installations expected later this year.

Looking ahead

2019 is already set to be another enormously successful year for Netwise, with many exciting new projects already green-lit for delivery in the first few months of the year.

We enter 2019 with a number of major developmental projects already in motion for Q1, and excitedly bring on-board new clients in the artificial intelligence, crypto, digital research, voice communications, investment management and storage technology industries.

Despite being a little late, we’d like to wish all of our stakeholders a fantastic New Year. We look forward to sharing it with you.
