Connection Security

How resilient is your Data Centre? How many fibre feeds does it have and where do these feeds come from? In the news recently was a story about the majority of west Africa being cut off from the internet due to a fault in the cable that runs from Portugal and Spain to South Africa via west Africa. The initial reports suggest that 70% of Nigeria have had their bandwidth cut as the remaining 30% takes up the load. Some may view this as a good thing as those pesky Nigerians who want to transfer millions of $ into our accounts so they can make themselves and us money, will not be able to send out any more emails! On a serious note, the bandwidth blackout has had a major effect on the government, banking sectors and the mobile phone networks. The lack of communication has left the country struggling to maintain normal activity.

Does your facility have diverse feeds? Do you know the routes these diverse feeds take? It is all very well having a resilient facility that has multiple feeds, but if both feeds exit the premises together, or at any point on their journey follow the same path, there is a large point of weakness to the connectivity of your Data Centre. With the country's infrastructure being dug up over and over again as water mains burst, sewers get clogged and broadband improved, there is increasing risk of damage to the fibre optics that service your facility. Being prepared and looking into having true diverse power and connectivity feeds into your Data Centre or Computer Room is a must for any business that relies on 24/7 connectivity.

Green Repercussions

The EAC (Environmental Audit Committee) has commented today that they believe that if government departments fail to cut their carbon emissions in line with their Carbon Reduction Commitment (CRC) plan, that the taxpayers will have to pick up the bill. The CRC plan charges companies £12 per tonne of CO2 they release or expect to release in a year. Using energy saving technology to reduce emissions and increase efficiency will allow companies to be ranked on percentage of CO2 reduced and will then be given a rebate if they succeed or exceed the 12.5% reduction by 2012.

The government's plan is to give companies an incentive to reduce energy consumption and they expect the savings to more than pay for the £12 charge, making a net gain for the businesses involved. The EAC are suggesting that this plan could come back to bite the government if they cannot achieve their own targets, meaning the government would have to take money out of the national budget to pay for their own shortcomings.

There are widespread worries that a 12.5% reduction in CO2 emissions will be hard to attain for many companies.

In the words of Lance-Corporal Jack Jones "DON'T PANIC"!! This is far from a bad thing for Data Centres. As we all know, Data Centres consume around 3-4% of all power in the UK. 12.5% of this equates to the equivalent of a 200MW facility!

Reducing every Data Centre and Computer Rooms power consumption by 12.5% may sound like an impossible challenge, but in reality it can be a very simple to achieve.

Migration Solutions developed ERA (Environmental Report and Assessment) which concentrates on all aspects that affect the running of a Data Centre or Computer Room and advises clients on how to improve their efficiency and as a result, reduce their power consumption and costs. Using the advice provided by Migration Solutions, estimated savings that will be free to implement could save between 5-10% of your facilities power costs. With a small amount of expenditure you could expect to see a reduction of 12-20% in power consumption. So the CRC may not be as hard to fulfil as you may first think!

Broadband Bashing

ISP's (Internet Service Providers) are in trouble again after the release of Ofcom's latest report. There has been extended debate about the legalities and honesty of ISP's 'up to' speed clause in their bandwidth package, because the majority of customers do not and cannot attain the speeds suggested by them.

The Ofcom report focused on the 8Mb service provided by ISP's across the country. Their findings revealed that only 9% of users who subscribe to an 8mb service could attain above 6Mb and that the majority of users could get less than half the quoted amount. The ISP's argue that customers within a close proximity to the telephone exchange attain close to the quoted bandwidth speeds and because of distance and drain on the service by other users, customers who are further out get a slower service. Ofcom also revealed that the majority of 8mb connections could not even support 8Mb, and actually only had the capacity for 7.1Mb.

While the rest of the country has to abide by advertising laws and provide the customer exactly what they offer, ISP's have the ability to suggest that you will receive a service that they cannot provide. The two words 'up to' are an unfair loophole for consumers considering that the majority of customers are not getting the advertised amount. The issue that Ofcom is attempting to solve is to allow the public to get broadband connections that are consistent and that can be regulated. If companies are willing to install the infrastructure to support fast internet speeds such as ADSL MAX or fibre, then they should be allowed to advertise its availability - but not before the service is available.

So what does this report hope to achieve? The government wants the ISP's to be honest about the service they provide so that they can reach their target of the whole country having a minimum of 2Mb internet speeds. If the report has the desired effect, ISPs will have to improve their infrastructure and improve their service, which allows the public to receive what they pay for and not a substandard service.

The result of increasing internet speeds across the country will be a larger demand for Data Centre space, as people access websites, store information and extend their dependency on online services. The competition will increase speeds and drive down prices which will make Data Centre space more affordable and desirable.

Is a wireless Data Centre possible?

Does your Data Centre look like this?

The majority of Data Centres and Computer Rooms in the UK have disorganised cabling and patching which inhibits air flow and reduces efficiency. The organic nature of a network infrastructure often starts with the best intentions and neat cabling, but develops into a sprawling mess when 'quick patches' are made and then left in position. Five years down the line and you can't see the rear of your servers!

There are so many benefits to a neatly patched facility. Connecting your servers through a patch panel allows quick organised alterations to the network while maintaining sub-floor cabling and air flows through the Data Centre. Using cable management arms inside cabinets keeps all cables neatly together and easily traceable, and allows hot air to exit quickly and unobstructed from the servers, which reduces the need for the computer fans to work as hard, reducing power usage. But could we do away with cabling all together?

Companies like WiTricity are already researching safe, wireless power transfers with the idea that in the future, you will be able to walk into a room or your office and phones, laptops and and mp3 players will start charging automatically without being connected to anything. The potential for this technology is unlimited, giving true freedom for you and your gadgets. But what about Data Centres and Computer Rooms? If the same technology was applied, power cables could be removed which would improve air flows and therefore cooling efficiency. The question remains though, would the amount of power required be able to be safely transferred to the equipment reliably? And, more importantly, being only around 40% efficient vast improvements will have to be made to make it a viable solution in a Data Centre environment.

So if wireless power is a possibility, what about wireless networking? Cisco are currently operating and improving a wireless Data Centre. Their facility uses Power over Ethernet and Wi-Fi Ethernet to create a network cable free Data Centre. They have up to 27 routers in the ceiling per meter to give excellent redundancy and bandwidth levels. This technology, along with wireless monitoring and management like the service provided by Synapsense would create a true, wireless Data Centre. Synapsense gives an on-demand picture of temperatures, humidities and pressures within a facility which could replace an expensive and often in accurate CFD (Computational Fluid Dynamics) test.

While CFD has its place, it lacks the ability to map each individual facilities server utilisation. This new method would allow a Data Centre Manager to fine tune a facility so that servers are always in the most efficient area. With the ability to move servers and racks around freely to optimise cooling, with the only constraint being floor grill placement, super efficient data centres could be just around the corner and they could, just possibly be wireless!

Migration Solutions is a member of The Green Grid which is focused on advancing efficiency in Data Centres. They have also recently received Information Age's award for Best Data Centre Innovation for ERA - an Environmental Report and Audit which aims to help data centre owners to save money and the environment with no or little financial outlay.

Swine Flu

The world has gone swine flu crazy! The public has become paranoid about contracting swine flu and doctors have been inundated with appointments from people who think they have the symptoms. The NHS has just launched a telephone and online service to handle the huge number of enquiries and to provide Tamiflu without the need for a visit to the doctor, where the infection has potential to spread rapidly. Record numbers of people have been phoning the service and accessing the online website, www.pandemicflu.direct.gov.uk.

In the first hour they received 10,000 phone calls and 9.3 million website hits!

NHS direct normally run at around 110-140 GB of bandwidth a month with people looking for information on their website. With their dedicated swine flu website coming online, in the first 3 hours they used 1,404 GB! The new website does use a less bandwidth-heavy design, but even taking that into consideration, they had a rise of 2,453% in bandwidth used! If you compare their normal bandwidth figure (110-140GB a month for 2006-2007) with that of 2003-2004 (25GB) you can see how much of an increase in the reliance on the internet there has been to help find information and diagnose problems.

Is the internet becoming a core utility? The majority of the country use the internet daily to find out everything from directions to talking to relatives abroad. We rely on it as our library, dictionary and news source. When did 'Google it' become an acceptable business term!? Lord Carter's Digital Britain report has promoted the need to give everyone in the UK access to broadband internet by 2015. When you move house, ensuring that you have internet connectivity has become as essential as organising your electricity, water and gas suppliers. If the internet is becoming a core utility, should it be treated as such? Should each house have a bandwidth meter to measure 'how much' internet you use? That way, you could could pay for what you use and not what you think you will use; better value for money for the consumer.

Using the same methodology in Data Centres would reduce the amount of website downtime that is linked to company's exceeding designated bandwidth limits. Companies wouldn't have to second guess the amount of bandwidth they might use which would make Data Centres more competitively priced. There would be a larger focus on the cost of power and subsequently the efficiency of each Data Centre. With more efficient Data Centres, less power would be used and there would be less CO2 being released so the Data Centre operator, customer and the environment would benefit!

Migration Solutions created a Environmental Report and Assessment to look at how a Data Centre operates and areas that could be improved within the facility and operations. The ERA report comes with an entire section on changes that can be made to help your Data Centre run more efficiently and effectively. These improvements range from free, low man-time changes that can yield a 5-10% reduction in power costs to major works which include changing a facility layout, rack layout and replacing old plant equipment.

Power to the People

Have you got power? Do you know where your power comes from? How long can you survive without power? Many companies in Kent are asking these questions as they face a third day without electricity. Up to 100,000 homes and businesses have been left without power after a suspected vandal attack on an electricity substation in Dartford. Many businesses have had to close as they cannot function without power and only facilities with backup power generation have been able to continue their operations as usual.

For those who need to keep their businesses going, there has been a huge demand for generators and fuel. EDF who own the substation have been trying to restore power and have been providing backup power in 3 hour long, rotated sessions where possible. A number of Data Centres in the area who do not have generators on site have been paying higher than usual prices to source power at short notice. They are starting to realise how fragile the national grid is in the UK and how there is an increasing need for standby generators with present and expected, future power problems.

So do you know where your Data Centre gets its power? Do you have diverse feeds to maintain resilience? In a worst case scenario, how long could your facility survive without mains power and without generator fuel? For the majority of Data Centres with standby generators, no more than 24 hours worth of fuel is kept on site. According to the Uptime Institutes tiering standards, a tier 4 facility is only required to have 4 days of fuel while a Tier 3 only 3. What happens if fuel trucks cannot get to your facility to refill the tanks? Some Data Centres claim to hold enough fuel for 90 days of normal operation. This may seem very expensive and sound like overkill, but talks of London running out of power in the near future and past fuel price strikes are leading business continuity experts to recommend larger fuel tanks to minimise potential impact on critical business systems. How vital are your systems and how long could your facility survive?

Will BitTorrent ever beat the Data Centre?

With the Pirate Bay and Kazaa deciding to go legit, the way we access music, films and software could be about to change. Peer to peer (P2P) transfers of files, legal or not, has boomed since Napster's break through in technology in 1999. The introduction of BitTorrent's in 2001, a file sharing protocol that allows millions of computers around the world to share files quickly, has made sharing files easy and fast. The technology works by taking the original file from a user, and when it is downloaded, splitting that file into many small chunks. When there are multiple users downloading (or providing) a file, BitTorrent allows people to access these little bits from different people, which minimises the amount of bandwidth traffic that the original 'seeder' has to use to share the original file. The protocol ensures that the rarest part of the file is provided first to ensure high availability. As a result, large files can be downloaded very quickly, significantly faster than a normal website download could be achieved with multiple downloaders.

The popularity of this method of data transfer has exploded and now, although there are conflicting reports of actual amounts, around 30-50% of all internet traffic is thought to be from BitTorrent up and downloads. IsoHunt has claimed that there are 1.7 petabytes (1,000,000 gigabytes) being shared by their sources. Although BitTorrent downloading is popular, it cannot guarantee a connection to the file you require.

When you download a song from iTunes, you are connecting to their server in a Data Centre directly. You have a guaranteed connection speed from the Data Centre via a fibre optic cable. The only limitation to the speed you receive that file is the Internet Service Providers (ISP) network and your own personal internet connection. Theoretically, you could connect to the Data Centre at 14 terabits per second via fibre, which would effectively produce instant downloads. The reality is that fibre transmitters limit the possible bandwidth of fibre and that PC's cannot connect directly to a public fibre connection. Additionally, most bandwidth gets limited by connection via copper cables when connecting to a computer as it is a vastly cheaper method of data transfer in a localised area.

When you download a file from a P2P or BitTorrent network, you are connecting to individual PC's in the majority of cases. You are limited not only by your own computer, bandwidth and ISP, but by the person's that you are connecting to. BitTorrent is considerably more efficient at using this method over P2P due to the fact that it downloads many small files from many different users which allows the for an increase in availability. The limit to this technology appears when connecting to another user. If you could guarantee the connection speed there would be less of an issue, but connecting to P2P networks requires reliance on other users having the file you want, and that they have their computers switched on so you can receive it. In a Data Centre environment, a file would always be available.

So will BitTorrents ever replace the Data Centre? The nature of the connection method and the process that allows a BitTorrent file to be downloaded requires many people to have the same file and an active internet connection. There is no guarantee that you can download a file and each file that is not downloaded would lose someone money. While BitTorrent may be great for the free and illegal file downloading, the lack of control would make it hard to charge for the downloads. Aside from this, the majority of Data Centres require servers for their raw computing power and storage capabilities. BitTorrent software cannot recreate this and even if it could, the running costs would be significantly higher and the synchronisation impossible to maintain.
