London East Build Blog – Weeks 52 to 55

A slightly later-than-planned update to the build blog this time around, thanks to time spent on more critical development works, as we head into a period of extended activity on-site at NLE.

The last four weeks have seen excellent progress across a varied range of areas, bringing a number of outstanding side-projects to a close, and solid advancements made on some of the remaining primary tasks.

Weekly overview

We’ll be keeping the update this week brief, so as to retain focus on real-world progress, however this post will serve as a general visual update to our readers, showing advancements across the various areas which have seen the most apparent change.

Front Gates — As seen at NLC, we’re blanking off the gate and turnstile sections of the front compound fencing, for added visuals and security – the turnstile sections are to follow

Checkerplate — The final outstanding checkerplate has now been installed, seen here in the ground floor level loading bay

Loading Bay Guard — Both the ground and first floor level loading bays have had checkerplate and bash protection installed, allowing the forklift to bump into the stops here for accurate, guess-free loading

Louvres — The intake louvres are now complete, pending their filter frames being installed in due course – here you can now see both top and bottom runs in place

Roof Sheets — This is our shipment of soaker sheets for the roof aperture profiles, which will take the extraction cowls

Roof Louvres — A view of some of our newly installed extraction cowls, as fitted to the roof of the cold corridor for Data Hall 1 – these will take warm exhaust air out to atmosphere when not required for recirculation, and are in this position to avoid any possible heat loops with the intake side of the primary cooling system

LV Plinths — Our LV rooms have preparations well underway to receive the main switchboards – the first part of this is preparing the open floor apertures for the incoming custom equipment plinths

Boards — Here we see our custom PDU expansion boards which will affix to the bottom of our Mardix PDUs in the data halls, allowing for our circuit monitoring to be installed on each rack feed

Ceiling — We’ve now started installing the ceiling tiles, as overhead works on the fire detection and lighting systems reach their conclusion – this has really started to finish off each room, giving a better indication of the finished surfaces

The most keen focus has been spent on the cooling system, in terms of the handling of air in and out of the building.

Beyond the visible updates as presented above, we’ve also been able to continue with underlying developmental plans for the remaining work phase, including aspects of power and connectivity.

Our fire contractors are now close to completion, which will be another major system milestone checked off very soon, as we march towards client deployment readiness.

What else has been happening?

It’s been a bumper start to Q2 here at Netwise, as we help a wide range of new and existing clients grow and deploy in our London Central facility. We’ve also started showing new prospects around London East as it moves nearer to completion, with a range of racks in the first pod now allocated to incoming clients.

We’re also close to pushing out a press release announcing our first major on-site carrier, so keep an eye out for that in the coming weeks.

What’s next?

Works are continuing on power, fire and connectivity. These are the main focus as we move towards the summer months, and to our forthcoming launch – watch this space for updates on when our first on-site events will be held.

How much colocation space do you need?

Your business has grown, and you’ve been hoarding every bit of data you can get on the off chance that it will help you in the future. Now, you’re running out of space, and you’ve started looking for server options. In passing, you hear a new term, “server colocation,” and it sounds exciting!

Just one problem, what is server colocation, and how much space do you need to get started?

Before we hop into the definition, ask yourself, will you be contracting with a cloud server company, or will you be building a server in your office? If you said “in my office,” then congratulations! You’ve come to the right article.

What is colocation?

At its very base level, colocation refers to renting space for server equipment in a data centre with other businesses.

More technically speaking, you need to make sure that you have room for all of your business’ essential technical needs and then some. That means the right amount of space to deploy your systems both now and to cover immediate-term growth.

So, let’s go over how much space you’ll need for every common type of organisational deployment, so you can plan correctly for your own colocation projects.

For the smaller company, Per Unit Colocaton

When a business is just starting to invest in colocation space, or if they’re smaller and don’t need that much physical capacity, they will usually buy space by the U (or Unit).

So, what’s a Unit? One “Unit” of racked colocation space is approximately 1.75″ tall. Servers and related equipment are designed to accommodate rack units, by mounting into the rack on ears or rails. The smallest space denomination is 1U, or a single rack unit. This would accommodate one server or small network device.

Other common space allocations include 2U and 4U, which cater for larger servers, or small clusters of hardware.

Stepping up in the world? Go for a Quarter Rack

The next step up in the server colocation world is a quarter rack (typically 8-10 Units of useable rack space).

A quarter rack is for small to mid-sized businesses that need to deploy slightly larger systems, comprised of multiple hardware sets. This may include a firewall, a couple of switches and a small cluster of servers and/or storage arrays.

So, why is this called a “quarter rack?” Well, the typical server rack consists of 42 Units of space. A quarter rack has ~25% of the full rack segregated and lockable, dedicated to you alone as the sole tenant.

A quarter rack with Netwise starts from around £164 per month with the minimum 1 amp power allocation.

Bigger is better: consider a Half Rack

Half rack colocation is excellent for mid-sized businesses that’re seeing a lot of growth. Usually, a half rack contains around 20U of server space.

A half rack will cost you £299 per month with the minimum 2 amp power allocation. This gives you a greater degree of deployment flexibility when compared with a quarter rack, and also allows for more power-hungry systems to be deployed with ease.

The Big Kahuna: Full Rack Colocation

Full-rack colocation is the best for larger companies that have more substantial systems, which tend to throughput lots more data.

This solution is ideal for growth, giving an excellent platform from which to grow, and the greatest amount of available in-rack power. A full rack, with the minimum 4 amp power allocation, is £439 per month.

Full racks let you expand as you wish into a 42U enclosure, offering the most control over airflow, and best installation practices.

To get an enterprise-grade rack with locking cabinets at Netwise, we would advise you to call our customer support to talk about a custom solution.

What are your server colocation needs?

Whatever your needs, we’re the best colocation company for you! Finally, you can expand your business with peace of mind, knowing that you will not be running out of space anytime soon.

Not 100% sure what you need, or are you confused by anything in this article about server colocation space? You can feel free to give us a call at any time!

London East Build Blog – Weeks 49 to 51

Things are really heating up now in terms of progress on-site at NLE, as we document another three weeks of work at our forthcoming data centre.

We’re almost at the one year mark in terms of when we first gained access to the new building, and despite some setbacks early on due to the Coronavirus pandemic, we’ve been extremely pleased with how quickly we’ve transformed the site from shell to data centre.

We’re not quite there yet, but we’re getting ever closer!

Weekly overview

The last three weeks have seen tremendous progress across a wide range of project areas. The most notable changes have centred around the physical adjustments to the rear of the facility, as the first set of louvred intake panels are cut into the exterior walls for Data Hall 1.

Speedgates — Our custom cable cover ramps have been installed as part of our client flow speed gates

Cooling — The coolers for Data Hall 1 now have their water supply and drains plumbed in

Fire Panels — The fire panels have started to have their containment installed, with cables now run in to them for future commissioning

The black textured wall in the meeting room at the NLE NOC also doubles as a handy pin board, which is ideal for displaying various technical drawings during the build process

Pod 1 in Data Hall 1 is now fully assembled, with both automatic doors now installed and powered

As we hope is self-evident, the visual and functional change on-site has been noteworthy, to say the least.

Big advances have been made in containment, which helps move the project along in many areas. Our fire contractors are now able to bring all systems together, and complete the VESDA and extinguishant panel integrations with the main building system.

Having Pod 1 reach point of completion from an assembly perspective is also a major project milestone, and gives a tangible focus point for any tours of the site ahead of it opening.

What’s next?

Next week we will reach 12 months on-site at NLE, although due to COVID-19 restrictions early on, we’re probably more like 9 months of true work into the project.

The next set of louvres will be installed in the next week or so, along with further works on various open projects. This all falls alongside larger project work, which will see broader stroke progress as the build continues towards full onlining in the next few months.

Your complete guide to understanding data centre tiers

The concept of a data centre may seem simple at first glance. After all, it’s effectively just a warehouse with stacks and stacks of humming, immobile servers. However, those servers may hold critical data and operate critical systems for your company, or the companies you rely on everyday. Are you well-enough prepared for a power outage or equipment failure?

Any expanding business needs to be aware of the challenges that come with choosing the right data centre for your needs. Luckily, there are universal data centre standards that allow you to evaluate the right level of security and stability for your company.

What are data centre tiers and how can your choice of data centre affect your business? Read on to discover the data centre tier ratings explained. You’ll find out what differentiates a simple warehouse from a high-tech facility, and how you can choose the best data centre for your business needs.

Data centre classification

Data centre classifications are consistent and regulated worldwide thanks to the standards created by the Uptime Institute in the mid-1990s. The institute is a neutral third party that inspects data centres and places them into one of four tiers of quality and reliability.

Standard data centre tiers

Tier differences are generally determined by two factors. The first is the ability to stay up and running even through repairs and necessary maintenance. The second is redundancy. This refers to the ability to continue functioning even if a necessary resource such as power or cooling were to fail.

Tier 1 data centres

A Tier 1 data centre is the most basic level of data centre, essentially a warehouse with small-scale supporting infrastructure. This infrastructure must include:

An uninterruptible power supply (UPS) which instantly transfers the power supply to a stored battery. This protects against outages or spikes, but not for extended periods of time.
Dedicated equipment for cooling the machines.
A backup generator for longer periods of power outage.

Tier 1 data centres are simple and can be more vulnerable to unexpected outages or failures. They also have to periodically shut down completely for maintenance, making systems held there inaccessible during this time.

To certify for Tier 1 status, a data centre must have no more than 28.8 hours of downtime per year (99.7% uptime).

That may not seem like much, but for many businesses, it is crucial that their data is available at all times. If you have ever tried to navigate to a website and found it to be down for scheduled maintenance you will recognise first-hand just how frustrating those 28 hours can be.

Tier 2 data centres

Tier 2 data centres are the most common type of data centre worldwide. Most private enterprise data centres held within offices in the UK fall under tier 2.

Tier 2 data centres are facilities with greater ‘redundant capacity’. This refers to their ability to keep functioning through disruptions such as power outages or scheduled maintenance. In addition to backup generators and cooling systems, tier 2 centres can include:

Energy storage units such as batteries.
Additional cooling equipment such as cooling towers and condensers.
Modular components which can be removed without shutting the entire system down.

Tier 2 centres are less likely to have to shut down for maintenance. Rather, maintenance can be done on just one part of the system, while the rest continues to run. However, shutdowns may occasionally be necessary for critical infrastructure support.

Tier 3 data centres

Tier 3 data centres are likely to be the highest level of data centre most businesses will ever need. Tier 3 data centre uptime can reach 100%. Many tier 3 sites do not need to ever be shut down.

A tier 3 data centre also requires additional backup power and cooling systems compared to a tier 2 centre. Tier 3 data centres in the UK are protected from both planned maintenance and shutdowns and unexpected events such as power outages.

Tier 3 sites are best suited to businesses that take uptime seriously, and need to know that their redundant systems are fed by infrastructure that makes full and proper use of this, with power and network separation for an always-on approach to maintenance and faults.

Tier 4 data centres

While the concept of a tier 4 data centre is possible in some regions around the world, this is not actually possible in the UK, thanks to the National Grid. You need access to two electrical grid operators to meet the tier 4 requirement, which can only be achieved in areas that have access to this type of power delivery methodology (while also achieving all other requirements, of course).

Some UK-based facility operators will attempt to pass of a tier 3+ site (a tier 3 site with systems that exceed the tier 3 requirements) as a tier 4 site, however it is worth remembering that this is nothing more than misleading marketing.

In truth, a tier 4 site adds little-to-no operational advantage over a tier 3 counterpart, as having reliable generator infrastructure negates the need for diverse commercial grid access.

Multi-tier data centres

Multi tier data centres have become more common in the past ten years. This refers to data centres that support mixed levels of tier classification.

For example, the most critical systems may make up only 10-15% of a company’s needs. These can be protected with tier 3 or 4 level standards, while other systems which are less critical to overall upkeep can be protected with less rigorous standards.

This reduces expenses on the company’s part and allows data centres to be more agile and versatile in the companies they serve.

It’s very common for top colocation service operators to deploy facilities that existing somewhere between tier 3 and tier 4, often being referred to as tier 3+ (though this is not an official classification offered by the Uptime Institute).

Choosing a data centre for your business

Data centres choose to invest in tier certification. They hire representatives from the Uptime Institute to evaluate their centre and give it an official classification.

So, if you see a data centre company has a tier rating, you can trust that they have taken every step to ensure that their capabilities can be trusted. Data centre tiers are a sign of trust between the centres, their clients, and a neutral third party.

Our data centres in Central and East London are world-class facilities with a number of accreditations and certifications. Contact us today and we will help you determine the right level of security for your needs.

How to choose the best server colocation in London

The colocation data centre market is worth over $54.8 billion. It continues to grow thanks to an increasing global reliance on technology and the related need to increase the scale of IT services in general.

Managing technology requires time, money, and effort, especially when businesses attempt to create solutions in-house. Server colocation allows you to share space with other tenants in a centralised location, which is remote from your office(s). Professionals manage the equipment and network for you, keeping it safe and providing the right environment.

What is server colocation?

Server colocation allows you to share data centre space in a centralised, remote location. It provide businesses with space to install necessary IT equipment while also preventing operation or technical limitations and allowing you to control costs, support, uptime, and security.

What a colocation data enter does

A colocation centre is a physical location that stores data and IT infrastructure on behalf of businesses, and in some rarer cases, individuals. Services include power, cooling, physical security, network connectivity, and resiliency.

These centres offer different types of services as well, allowing you to customize your size and power usage based on your needs.

Types

Wholesale colocation is best for large corporations and service providers. Your space is separate from other tenants, which increases security. Space is sold in square feet or based on total available power, and your price depends on your power and space requirements.

Retail colocation is best for start-ups and SMEs. It provides a turnkey solution that allows you to get set up quickly by providing racks, power, PDUs, network connectivity, and IP addressing. Businesses lease space and receive power at a threshold. Your fees are based on your space allocation and power / network consumption.

Space can be sold in rack units, abbreviated as U. It measures the thickness of each server at 1.75″.

1, 2, or 4 unit colocation is abbreviated as 1U/2U/4U. It involves purchasing individual unit allocations but can be upgraded to include more space. 1U is small and considered entry-stage. The others are somewhat larger, but major businesses may require quarter, half, or full racks for housing more substantial systems.

Quarter rack location offers 10U of colocation space. Everything is stored in a private, locked cabinet. It’s a great option for small businesses and start-ups.

Half rack location is a mid-range option that offers 20U of colocation space and power feeds of 2-8 amps at 240v. It costs £299.00 – £479.00 per month. Lockable, segregated racks provide extra security. There are multiple connectivity options to fit your needs.

Full rack colocation provides a full rack or 42U of cabinet space. It offers more available power and is best for companies with larger IT systems. Multiple racks then allow these systems to be extended, with no upper limit on how many racks can be deployed as part of a single (or even split) system.

Benefits of server colocation

Businesses that aren’t using server colocation create in-house facilities instead. They provide more internal access and control but are complicated and expensive to set up, increase hiring costs, and can decrease uptime.

Colocation centres have several benefits. They increase efficiency, decrease energy consumption, are flexible and scalable, increase security, decrease downtime, and help you manage your budget more closely.

Colocation centres consider both network and physical security. They create several layers of security and threat detection to protect your network. They also monitor the location itself using CCTV and 24×7 on-site personnel.

Colocation centres offer predictable operational expenses. They offer regular fees for rack units, power, and bandwidth. Additional consulting or hardware resources may be part of your service fee or cost extra. Once you know these costs, you can find the total and work it into your budget.

A colocation centre should also be clear about what you don’t have to pay for. They can save you money in several areas, including hiring, power, and heating and cooling costs.

Server colocation is also a way to ensure you don’t lose profits from IT services that aren’t working like you need them to. The true cost of IT downtime depends on several factors, including the duration of the outage and the number of people impacted. It costs businesses an average of approximately $5,600.00 per minute and $140,000.00 – $540,000.00 per hour.

These are only some of the benefits of server colocation. As long as you choose the right provider, you could experience even more positive changes by placing your IT equipment in the hands of professionals.

Choosing server colocation

There are over 4,740 server colocation centres throughout the world, including at least 273 in the United Kingdom. Choosing the right one from this range of options is easier when you know what to look for. Consider factors such as space, power, connectivity, security, support, and price.

Determine how much space you need by looking at your power and infrastructure requirements now and in the future.

There are several ways to ensure you get the best price. Avoid bargain discount rates because they generally indicate poor service. Look at the prices of other server colocation centres in the area. Get referrals online or from trusted friends and family. Choose the best fee structure for you, whether that’s monthly, quarterly, annually, or hourly. Consider if you need to purchase or lease equipment.

There are also some questions to ask before choosing a server colocation centre. Learn more about their:

Security measures
Reliability
Flexibility
Data capacity limits
Support team

You can also look online to check the provider’s reputation. Look for their uptime and security records and check their certifications and history of audit compliance.

The typical server colocation contract lasts 1 – 3 years. Be sure you’ve chosen the best provider before signing anything.

Finding the best server colocation provider

Server colocation is one of the newest and most effective alternatives to in-house IT centres. It connects you with professionals to ensure your systems are secure and stay online.

Choosing the right colocation centre is a matter of considering your current needs and how your business will grow in the future. Find an affordable, scalable option that will adapt to your changing IT structure.
