London East Build Blog – Weeks 71 to 74

Now that raised floors have started to go back down, and termination of cabling is essentially complete, impactful visual change has slowed down slightly, however progress is still pushing forwards at great pace.

We’ve been preparing for some of the final trades to land on site to end-out phase one, which will include the CRAC pipework team and the wall fabrication team from earlier in the project, who will be finishing off some of the final cooling system segregation now that the fans are installed.

Weekly overview

Much of the change this time centres around supplementary cooling, VESDA / fire panels, and data cabling for things such as CCTV, access control and monitoring / system control.

We’re now very much in the end-out phase of the project at this point, which means that various elements that until now were operating separately are coming together quickly.

For example, our evaporative cooling units are now connected back to both their power delivery and control systems, meaning that they will soon be ready for their first spin up and test. This is the same for a number of the core systems which make up the infrastructure of the facility.

We now have most of the building-wide comfort cooling in place for client and staff areas, including here in the build room and customer lounge
Here we see the ceiling mounted AC unit mirrored on the other side of the building, and the same units are now also present in the NOC / office
We’ve also got three high performance models installed in each of the LV rooms, with room for a fourth in due course as and when required based on UPS expansion
Our VESDA pipework is now installed in Data Hall 1 and pre-emptively in Data Hall 2
This is the view of the installation in Data Hall 2, which we are pre-staging for future use, along with all other baseline infrastructure – this will speed up the commissioning process for this hall dramatically once it’s needed
This is the view of the VESDA installation in Data Hall 1
This is a slightly wider view of the VESDA installation in Data Hall 1, showing the various sampling pathways as they leave the main unit, and also showing the B-side PDUs for distribution to client racks, and the earthing bar for the hall
Here we see the VESDA pipework installed in Data Hall 2, along the blanking system at the rear which will eventually house the CRECs for this hall
The CREC units in Data Hall 1 have now had their power and control system cables installed, which brings them up to readiness for commissioning in due course
The ODFs in Data Hall 1 are starting to take shape, with containment now run in from both high and low levels – here, one of the newly installed cleaner sockets is also visible, as part of a wider ring installed throughout the building to support such requirements
This is the B-side ODF, with a range of cabling now run back to it to support various functions in Data Hall 1, such as CCTV, monitoring and system controls
Here we see the entrance to the first committed private pod in Data Hall 1, which after some forthcoming adjustments to access control and visual identity, will be handed over to the client in Q4
Another view of the pod entry door systems that we use with our APC racking and containment system, which are operated electronically
This floating, conduit-free cleaners socket is achieved by ensuring that it backs onto one of our risers, meaning all containment for the cabling is hidden from view, something we have done wherever possible for a clean installation
This is the cleaners socket as installed alongside ODF B in Data Hall 1, which due to its positioning does require conduit access to under floor containment
The UPS boards are now landing back in place in both LV rooms, having been removed during the flood cabling process
Another view of the PDUs which distribute B-side power in Data Hall 1, with all internals now completely terminated, and ready to hand-off power to client racks
We now have our new reception desk standing in place, which will be finished with branding and a glass security and visitor flow system in due course
Another view of the reception desk as placed in an approximation of its final position

We’re getting to the point at which photographing visual change is likely to slow down somewhat, as we move onto more detailed work such as the interconnection of critical systems, and the onlining of various electrical elements including CCTV and door access control.

Excitement is starting to build as the many months of extremely hard work from all those involved begins to show its final fruits, which will become all the more exciting as we start to see systems roar into life.

What’s next?

While build and installation works will continue in a few final areas – such as CRAC pipework, final airflow containment for extraction in Data Hall 1, and the end stages of general system containment – we are now also in a position to begin the early-stage commissioning process.

We are entering an exciting phase of the project, as things finally begin to slot back into place after a good few months of ordered chaos; a necessary evil associated with the extensive electrical work required to take the building from completed shell to functioning data centre.

Over the next few weeks, we expect to see the site visually return to a state of completion (for phase one), at which point the site will be onlined, and commissioning of critical systems will begin in earnest.

London East Build Blog – Weeks 69 and 70

We have more exciting progress to share in this instalment of the Build Blog, as cabling continues to run into the facility at pace.

This progress has been seen across the board, from the largest runs out to external connection points, right down to the smallest termination points inside of the Data Hall PDUs.

Weekly overview

In the last two weeks, we’ve doubled the labour force involved in the electrical side of the project, adding a dedicated cable gang to the on-site trades to help push through the final cable runs, most of which are very substantial armoured cables.

This has seen the vast majority of the on-site cable drums emptied and returned to the vendor, as the cables now lay in place, with termination well underway across the board.

We also have a dedicated jointer on-site, who is heading up much of the largest termination activity, such as inside the generator canopies.

The first set of cables that make use of the external ladder runs out to the transformer, seen in place here
Another view of the first set of cables on the transformer-to-LV room route
This run takes cables all the way out to the transformer enclosure – these are again in a trefoil cleat arrangement, as with the LV Room interlink cables
The GRP enclosure for the transformer now in place atop the previously poured base
The cables that connect to the transformer take a direct route around the perimeter of the front compound, with rear-mounted security panelling to be installed soon
Another view of this particular containment run in the front compound
This is the view back towards the building, with the containment and cabling penetrating the skin of the building, pending final capping and fireproofing
Some of the newly emptied cable drums, which have since had their contents run into the facility
Termination of the main LV boards is now well underway, with a view here inside one of the main enclosures in LV Room A
Another of the main enclosures in LV Room A, with the termination now complete
This is a view of one of the main enclosures prior to any termination, after glanding
Here we see one of the same enclosures mid-way through termination

This view under one of the LV Room floors shows the next layer of containment and cabling going in over the top of the base layer
A view of some of the ladder work on the first floor, which now contains the runs which will feed Data Hall 1 with protected, conditioned power
A look inside one of the PDUs in Data Hall 1, as the final termination begins
This view shows some of the cables as they make use of the riser in LV Room B
This is the view of the external containment which heads to the generators, as the cabling nears completion
Another view of the generator cables as they enter the building
A look across the rear of the generators, where this cabling will soon enter each unit
The generator cables enter the building here, and then pass into LV Room A for onward handling – these holes will all be fire stopped and finished with tight-fitting decorated panels
The transformer route shown here now contains all cabling as necessary to liven up the site during commissioning
Another view of the transformer cabling, with the earthing now in place
A view of the transformer cabling as it reaches the enclosure, ready for connection into the transformer once that is installed
Here we see one of our custom ODFs, of which there are two in Data Hall 1 for diversity – this angle shows the installed overhead cable ladder bridging across to Pod 1
The VESDA pipework installation is now underway in Data Hall 1
A look at the pipework as it begins to be installed along air pathways, in this case on the supplementary CRAC unit intakes, which now have their automatic dampers fitted
The pipework is also installed along the main CREC exhaust and recirculation louvres

This has been a fantastic fortnight for project development, with tremendous progress on the cabling side of things.

We’ve been very excited to see all of the cabling begin to disappear under the floor and into the risers, ready for termination and testing. We’re also very excited to see some additional visual elements installed, such as the bright red VESDA air sampling pipework.

What’s next?

We will continue with progress on all things electrical. As cable pulling nears completion, focus will shift more completely onto termination, along with supplementary power installations, including small scale non-critical power delivery to things like cleaner’s sockets.

Beyond this, the VESDA pipework installations will continue, and with the arrival of additional cabling for things such as the CREC control and monitoring system, this will also begin to take shape.

9 things to look for in your London data centre

Did you know there are around 285 colocation data centres in the United Kingdom? As the UK capital, London is the perfect place to house your critical infrastructure. But do you fully understand what makes a good one?

London has a lot to offer, from sound infrastructure to geographical safety. Read on as we discuss nine things to look for in your London data centre partner.

1. Security

Security comes in both digital and physical from when referring to top-quality London data centres.

Data centres can also be attacked physically. Therefore, you need to check the security of the facility itself. It should be monitored 24 hours a day with video surveillance equipment. 

2. Power redundancy

When you have a business that runs online, you need to make sure it is operating at full capacity through all eventualities. If you have a critical system that can not go down, what happens if a data centre runs out of power? 

One factor your London data centre needs is a secondary electrical connection. Most facilities will have this, and N+1 grid connectivity with a second power source is essential. 

Any failures in the power will not lead to a shutdown with this in place. When choosing a centre, ask what electrical backups they have. 

3. A good location

When you choose a data centre that is a long way off, then your networking costs increase. When it is closer to your place of operations, it is easier to respond when any problems or issues arise. This is what makes a London data centre such a great option for businesses in the city. 

Lights out facilities is the term used for centres managed remotely. Preferred by some, they are risk-averse and cost-effective, as management is away from areas prone to natural disasters. However, this is not a problem that impacts the city of London.  

This makes a data centre in London a great choice all around. They are safe and with so much easy access to the city, can be visited whenever you need to check on them. 

4. Provision of an SLA

service level agreement (SLA) is a binding contract that sets out what the data centre will provide you with. This needs to be studied in-depth, as it may contain hidden caveats within the small print. When something goes wrong, you don’t want the provider to leave you high and dry because you didn’t read it properly. 

Don’t be afraid to address these issues. If you want something added or removed, then discuss it with them. This may also help them get a better understanding of the coverage and service you desire. 

One area that is often hard to understand is accountability for security. Make this as clear as possible in your SLA. All of this should be discussed during your search, not when it comes to signing the contract.

5. 24 hour support

Problems can occur at any time. This does not just mean the middle of the night, but also on every day of the week, every single day of the year. Failure is not an option, because it costs people time and revenue. That is why the centre needs to be monitored and staffed around the clock. 

That does not mean staffing at the centre has to be consistent. In downtimes, less staff may be onsite or monitoring. However, someone must always be there to answer phone calls and give assistance. 

6. Reputation

Checking the reputation does not mean you won’t find unknown London data centres that are good. It is just that with ones that have a great reputation, you get a degree of certainty regarding their level of service. Speak to other business leaders and managers about who they use and get recommendations. 

In addition, when you sign up for a data centre you will be working together for a few years. You need to know they have a level of professionalism and service that will see you through. Ask the company themselves to provide references and testimonials to support their credibility. 

7. Geo diversity

Despite being an extremely safe place for a data centre, it is possible that accidents may happen. When they do and centres go out of action, you need to know the company has other centres across the country or region. 

If a disaster befalls the centre then another can keep your business up and running. Discuss this and see where their other centres are located. 

8. Certifications

Like any industry, the data providers will have a number of compliance certifications. These are to protect the centre legally and safeguard you as a customer.

In addition to this, your industry itself may be regulated and have compliance, which the data centre needs to know about. For example, if you have healthcare records and the data centre does not understand the compliance related to record-keeping, then you may be liable. 

9. Data capacity

Data capacity for your London data centre needs to be scalable. Technology is constantly growing and so are the needs of your business. The data centre needs to have the capacity to provide for you, then be able to forecast what else you may need, and be able to increase it quickly. 

Some data centres are huge and can support Amazon sized websites, while others may be much smaller. None are wrong or right, as long as they have the capacity to serve you now and in the future. 

Selecting a London data centre

Now you know the benefits of a London data centre, you just need to find one suitable for your business. Speak with a number of providers and make sure to go through the SLA in depth. 

Your first stop should be Netwise. We have colocation centres in the capital with state of the art facilities. Get in touch today and let us keep you connected.

A small business guide to a London data centre

Decades ago, society was content with simple TV broadcasts from only a few channels, and communication was as simple as snail-mail. When computers first came on the scene they were giant machines that would occupy whole rooms.

But as technology has evolved, computers and equipment have shrunk and become cheaper. With this evolution has come rising data processing demands which show no sign of slowing down.

As technological advances continue to change the way companies do business, the need for data and power increases. Data centres are the powerhouses of the industrial world, and a London data centre may be just the thing you need. 

What is a data centre?

The internet is now considered a daily essential, and almost everybody owns a smartphone, allowing 24/7 connection to the online world. With over 60% of the world’s population online at any given time, the internet plays a huge role in our lives. This means the demand for real-time data transmission is at an all-time high.

The need for computers and other networking equipment that can handle these requests was the driver for the emersion of the modern data centre.

Data centres are computing and networking facilities tasked to collect, store, process, and distribute data. They are responsible for data backup and recovery, as well as networking. 

Data centres connect communication networks so users can access information remotely. They host websites and manage e-mails and messaging services. Data centres also support cloud storage and e-commerce transactions. 

Importance of data centres

Almost every modern business needs a business data centre. Large corporations or government institutions may choose to build and manage them in-house if they have the resources, but most companies choose to rent services at colocation facilities.

Companies that handle finance, telecommunication, retail, education and social networking services process tons of information daily. Any business that produces or uses data requires a data centre to optimise running its operations. Data centres offer fast secure access to data that cannot be matched.

The idea of storing data and resources on home or work computers is quickly being replaced by an offshore storage mentality. Many companies are migrating their data to data centre services to reduce the cost of running in-house servers and to ensure failsafe reliability that cannot be achieved in the home or workplace. 

What Netwise’s London data centres can do for you

Data centres in London are far more than just safe and secure facilities equipped with reliable power and network access. They are quickly becoming a valuable addition to many businesses, as a dependable extension of their IT team.

The Netwise team prides itself on quality service and round the clock care to ensure your data is accessible and protected. 


Data centres are built to provide around the clock service. With every consideration taken care of, you can be sure your servers will be running around the clock for you and your clients.

  • Multiple power sources that are stable and uninterruptible
  • Super-efficient cooling and ventilation
  • Reliable backup generators
  • 24×7 technical support and security
  • World-class network and connectivity services

Power outage protection

Onsite power failures are incurable when they result in a loss of data. Technological and natural power outages can cause disaster for an organisation. Loss of power for as little as 1/50 of a second can trigger events that can keep equipment unavailable for anywhere from 15 minutes to several hours. 

Outsourcing control to reduce the impact of a power failure is a great way to ensure this doesn’t happen to you. Date centres make use of both grid power and independent generators and UPS’s. This means you’ll be protecting yourself against power outages and ensuring your servers are never out of action.

Clean power

Utility power isn’t always clean, creating a sustainable future is everyone’s responsibility. This is why Netwise uses 100% renewable energy sourced from the wind, sun and sea. Our data centres are some of the greenest facilities in Europe, helping you and your company reduce your carbon footprint.

London East Build Blog – Weeks 66 to 68

Focus on the Build Blog this time around has been firmly on progress with cabling and containment, which continues to develop across the entire site.

A hefty quantity of the largest internal cabling is now all in place, totalling around 8 tonnes. This will now be terminated, along with a host of smaller internal cabling, while additional large external cabling is run in thereafter, as we head ever closer to energisation at London East.

Weekly overview

We’ll get straight into the photos again this time around, as we take a look at cabling and containment developments on-site at NLE.

Containment has now firmly breached into the exterior areas of the new site, with the runs to the four generators taking shape here
Another view of the generator containment as it works its way around to the point of entry on each gen set
A closer view of the twin ladder runs out to the generators, to account for the large quantity of cabling required to connect these units back to the main switchboards and controllers
What look to be simple drops across to the generators actually required considerable effort, as solid concrete and brickwork edging had to be excavated to allow for the ladder to pass through to the required location
On the other side of the front compound, the twin ladder runs to the transformer have started to be installed
Here we see the supporting slotted channel being prepared for installation on this solid block wall, which will house the transformer cable runs as they pass into the building
The external skin of the building has been modified to allow cabling to enter and pass along this route
Here’s a view of the uncovered cable ladder which sits under the floor in the ground floor access corridor
Here we seem a temporary blanking panel in place until the ladder is ready to pass through the building – additional tray is being run in to hold AC pipework for traditional systems that will support supplementary areas of the building
The transformer base is now ready for the installation of the GRP enclosure, and the transformer itself
This is a view inside of LV Room B, as some of the large ~300kg inter-room cables are run in, which will link the LV boards for various functions / reasons – they are simply laid in loose at this point in time
This is the drum of cabling for connecting out to the generators, which clocks in at 2.2 tonnes
One of the first drums to be emptied – this was a 1.8 tonne spool, which is now all run in under the floor between the LV rooms – this will be modified and become an outside table for clients to use
Another finished drum, slightly smaller this time, equating to around 1.2 tonnes
A look into LV Room A, with the cabling being pulled into its trefoil cleats
A view into the main LV Room cabling route as they enter LV Room B, showing the cleats as they hold the cables down to the floor mounted channel
Another view into LV Room B as the routes continue to take shape, and the tails are fed all the way into the boards
Earth cable being pulled into the floor, which again will interconnect the LV Rooms
A view into LV Room A, as the earth cables are laid into position ahead of cleating
Here we see the earth cabling being pulled into its cleated arrangement, which brings this main route to its full state
A look down the main cable route between LV Rooms, showing the multiple trefoils and earthing bundles and they run between the two main boards

As you can see, the main focus here has been on continued progression with cabling and containment, which will continue into the next instalment of the Build Blog.

As always, other works have of course been underway, both in the development of London East, and elsewhere across our ever-growing operation, however we’re keeping this post concise and on topic.

What’s next?

As with the previous ‘what’s next?’ update, we’re looking at more of the same over the next few weeks. We have a vast amount of cabling and termination to undertake, which we hope to see nearing completion by the time we next post to the Build Blog.

We’ll also be moving onto further work on fire and VESDA systems, and will be moving ahead with commissioning on cooling systems, as well as continued work on power, such as the roll out of ‘small power infrastructure’ (supplementary building-wide power sockets for cleaning equipment etc).
