Additional Upstream: 10 Gbit/s Level 3

This winter we are going to expand our upstreams with an additional, high-quality carrier.

In addition to the already existing, extremely reliable connections via M-Net and Telia Sonera (10 Gbit/s each) there will be yet a third 10 Gbit/s connection in our datacenter available from February 2012 on. With it we're investing in a new level of redundancy for our datacenter customers. In the most unlikely event that a fibercable is going to be damaged by a excarvator or somehow else, our clients would not even notice any constraints. The two other glassfiber connections would be taking over, as in such case our high end CISCO-equipment would route the traffic automatically and without interruptions of service.

The new carrier Level 3 is widely known for his quality. Being a TIER1-carrier just like Telia Sonera it features a total of around 100 000 fiber miles worldwide. Thus, Level 3 is considered as the biggest and best-linked carrier in the world. Besides the excellent European network of Level 3 it's especially the American continent which is connected very well by the U.S. company. This makes Level 3 to the ideal choice for us, because we already have Telia Sonera as upstream carrier which is connected to 90% of all european broadbandnetworks directly. Level 3 serves 18 of world's top 20 telecom carriers.

For our customers that means - besides the formerly mentioned redundancy - that they benefit from an even broader internet bandwidth, a remarkably improved worldwide routing by using three parallel upstreams and last but definitely not least, a much better price in regards to traffic.

Further, we will offer more upstreams and peerings in the near future.

Noch in diesem Winter werden wir unsere Upstreams um einen weiteren, qualitativ hochwertigen Carrier erweitern.

Voraussichtlich im Februar wird neben den beiden bereits vorhandenen, äußerst zuverlässigen Anbindungen via M-Net und Telia Sonera (jeweils 10 Gbit/s) eine weitere 10 Gbit/s-Anbindung im Rechenzentrum verfügbar sein. Damit investieren wir in ein drittes Redundanzlevel für unsere Rechenzentrumskunden. Sollte beispielsweise der seltene Fall auftreten, dass eine Glasfaserleitung durch einen Bagger oder anderweitig beschädigt wird, spüren unsere Kunden hiervon nichts: Die Internetanbindung wird durch nunmehr gleich zwei weitere Glasfasern aufrecht erhalten. Unser hochwertiges CISCO-Equipment routet in einem solchen Fall automatisch und ausfallfrei den Traffic um.

Der neue Carrier Level 3 steht weltweit für höchste Qualität. Genau wie Telia Sonera ist als er als TIER1-Carrier "upstreamfrei" und verfügt über rund 160.000 Kilometer eigene Glasfaserkabel weltweit. Damit ist Level 3 wohl der größte und am Besten vernetzte Carrier weltweit. Neben einem exzellenten europäischen Netz ist insbesondere der gesamte amerikanische Kontinent von dem US-Unternehmen bestens konnektiert. Damit stellt Level 3 für Giga-Hosting.biz eine hervorragende Ergänzung zu dem bereits bestehenden Carrier Telia Sonera dar, an den über 90 % aller europäischen Bandbreitennetze direkt angeschlossen sind. Level 3 versorgt 18 der TOP 20 Telefongesellschaften auf der Welt.

Für unsere Kunden bedeutet dies - neben der bereits eingangs erwähnten Redundanz - noch mehr zur Verfügung stehende Internetbandbreite, ein noch besseres, weltweites Routing durch den parallelen Einsatz der Upstreams von M-Net, Telia Sonera und Level 3 sowie letztlich einen noch besseren Trafficpreis.

Darüber hinaus werden in Kürze weitere Upstreams und Peerings folgen.

Number of the month: 2 + 7 = Decent Temperature!

Outside, red hot and tropical weather conditions, but the servers located at Giga-Hosting's datacenter, always keep a 'cool processor'. Thanks to 7 climate cabinets in our datacenter and to 2 cooling units on the roof top, a consistent decent temperature is kept, to care for the servers on our server floor.

In April 2011, the second level of our air conditioning system was implemented and this upgraded the former cooling capacity by another 150%.

7 Air Conditioning Cabinets / Recirculation Cooling Units

The 7 air conditioning cabinets are mounted in our data center on various locations. Our recirculating cooling units absorb the warm air stream exhausted by our servers on the ceiling level of the datacenter. This air is afterwards chilled by cold water, which is pumped through two cooling units on the roof top of the building and taken down to the server floor again. The cooled air will then be blown out through the grills of our double layered pressure floor directly underneath the servers.

2 Cooling Units

The 2 cooling units are roof top mounted, directing towards Munich's centre. The warm water from the data center is pumped up to cooling units above. It gets chilled in there and is being pumped down again to the datacenter below. If the temperature outside is cooler than at the inside, air condition is not only controlled by compressors but also substituted by using ambient air. Such results in energy savings and therefore cost reductions. Giga-Hosting's clients do definitely benefit from this effieciency directly.

This 'free-cooling', permanently remote controlled system disposes of 2 water circulations, separated from each other. In fact, two completely independent and redundant systems in each aspect are implemented. All pipes and drains for the air conditioning, but as well all electrical wiring was installed twofold. That stands to reason that we keep consistent decent temperatures in our datacenter for the server's "wellness".  Equally do the employees at Giga International feel well, as they are taken care of by chilling them in air conditioned offices and pampering them with ice cream and cooled soft drinks.

Zahl des Monats: 2+7 = Angenehme Termperatur!

Draußen ist heiß und tropisch. Aber die Server im Rechenzentrum von Giga-Hosting bewahren immer einen "kühlen Prozessor". 7 Klimaschränke/Umluftkühler im Rechenzentrum und 2 Kühlaggregate auf dem Dach sorgen für gleichbleibende angenehme Temperatur im Rechenzentrum.

Seit April 2011 haben wir die zweite Klimastufe für das Rechenzentrum implementiert. Damit wurde die Klimaleistung um nochmals 150 % erhöht.

7 Klimaschränke/Umluftkühler:

Die 7 Klimaschränke sind im über 300 qm großen Rechenzentrum verteilt aufgestellt. Die Umluftkühler saugen die durch die Server erwärmte Luft auf Höhe der Decke des Rechenzentrums an. Die Luft wird dann durch kaltes Wasser gekühlt, das von den 2 Kühlaggregaten nach unten in das Rechenzentrum gepumpt wurde. Die gekühlte Luft wird dann durch den dichten Klimadruckboden direkt bei den Server wieder ausgeblasen.

2 Kühlaggregate:

Die 2 Kühlaggregate befinden sich auf dem Dach mit Blick auf die Frauenkirche im Münchener Zentrum. Das erwärmte Wasser aus dem Rechenzentrum wird nach oben auf das Dach zu den Kühlaggregaten gepumpt. Dort wird es abgekühlt und wieder nach unten in das Rechenzentrum gepumpt.  Die Kühlung erfolgt nicht nur über die Kompressoren, sondern auch, wenn es draußen kühler als drinnen ist, über die Außenluft. Dies führt zu Einsparungen bei den Energiekosten, die dann auch an die Kunden von Giga-Hosting weiter gegeben werden können.

Das freikühlende und ständig remote überwachte System hat zwei getrennte Wasserkreisläufe. Es existieren zwei in jeder Hinsicht eigenständige, redundante Klimatisierungssysteme. Sämtlich Rohre für die Kühlung und auch die elektrischen Zuleitungen sind doppelt gelegt. Dadurch herrschen im Rechenzentrum immer gleichbleibend angenehme Temperaturen und die Server "fühlen sich wohl". Aber auch die Mitarbeiter von Giga-Hosting bewahren durch eine Klimatisierung der Büroräume, durch Eis und kühle Getränke auch bei schwierigen Anfragen einen kühlen Kopf.

100 % Freecooling in June!

It's summer in Munich. Although today it's a rather rainy day and the temperature isn't higher than 15 degrees during the day, it's still June and it's still one of the warmest months in the year.

With respect to the facts mentioned above it seems even more remarkable to me that both of our fully redundant air conditioning systems located on the roof of our datacenter are working in the freecooling mode (100% freecooling) right now.This freecooling mode means that there's not running a single compressor in the cooling chillers to cool down around 1500 servers in our datacenter today. The whole cooling process is done by using the cooler air from outside to cool down the water of our refrigerant curcuit. There are some pumps and ventilators left which are responsible for transporting the water and air from outside into our datacenter. But nothing else, no more power consumption.

As there's not running any compressor in our chillers at all, we're saving lots of energy. There's no doubt that we usualy save this energy during the winter and during the colder months in autumn and spring, too. However, our modern and high-quality cooling units are good enough to save this energy even during the summer - just like they are doing right now. And these savings are pure money what we redirect to our customers by making great prices and providing excellent services with highly-educated personal on site. It's a typical "win-win-situation". But in this case, we have 3 winners: The customers, the datacenter and our environment.

Number of the month: 2

Almost exactly 2 years ago we established a new datacenter with enough room for 4000 servers in Munich. This has been done in order to face the growing demand in colocation and dedicated servers and to reach an even higher quality level. The same building also contains our office rooms which enables us to deliver excellent support, 365 days a year (also on holidays and weekends).

When we started up, we had just one single server in the data center, but we are now already on the threshold of exceeding 1500 servers – and our business is expanding at an ever-increasing rate. The high level of customer satisfaction we have achieved through professional organization and a competent and always friendly support.

There is also another interesting number 2 of the month: First we had during the 2 years not a single power outage in our data center. Second, we also had no single failure of our internet connection. Other data centers would be pleased with such values that cannot be taken for granted. We owe this mainly to our high technical standards and equipment and of course our technical team.

We can take a little bit proud. It shows us that we are on the right track.

Zahl des Monats: 2

Seit fast genau vor 2 Jahren haben wir in München ein neues Rechenzentrum für Server- und Colocation-Angebote mit Platz für 4000 Server eröffnet, um der steigenden Nachfrage und dem hohen Qualitätsanspruch unserer Kunden gerecht zu werden. Im selben Gebäude befinden sich seither auch unsere Büroräume, um einen exzellenten Support, 365 Tage im Jahr (auch an Feiertagen und Wochenenden), gewährleisten zu können.

Starteten wir zu Gründerzeiten noch mit einem einzigen Server im Rechenzentrum, so sehen wir uns heute bereits die Schwelle von 1500 Servern überschreiten - und wir wachsen immer schneller. Die hohe Kundenzufriedenheit haben wir durch professionelle Organisation und einen kompetenten und immer freundlichen Support erreicht.

Außerdem gibt es eine weitere interessante Zahl 2 des Monats: Erstens hatten wir innerhalb der 2 Jahren keinen einzigen Stromausfall in unserem Rechenzentrum. Zweitens hatten wir ebenso keinen einzigen Ausfall unserer Internetanbindung. Andere Rechenzentren würden sich über solche Werte freuen, die nicht als selbstverständlich vorausgesetzt werden können. Wir verdanken dies hauptsächlich unseren hohen technischen Standards, der Ausstattung und natürlich unserem Technikteam.

Darauf können wir zu Recht ein bisschen stolz sein. Es zeigt uns, dass wir auf dem richtigen Weg sind.

Number of the month: 22

This time the number of the month represents the number of our 22 state-of-the-art Rittal racks which have been set up for the new colocation servers of our customers.

Each of those 22 Rittal racks is equipped with lockable doors and additional roof ventilation. We have installed these racks during the last months in addition to our existing tower racks and blade racks to be prepared for the increasing demand for server space in our datacenter in 2011.

The following picture demonstrates how our quality racks made in Germany look like:

Conditioning cabinets arrived and mounted

Additional cooling cabinets for our datacenter have arrived.

They have already been mounted. Right now we're starting to install the additional cool water canalization to the top of our building and the electricity.

Cooling capacity will be expanded by 150%

Continuing growth of our server fleet does not only require more space. It also demands an expansion of our cooling capacities. Such is necessary to eliminate the electrical energy, which is transformed by our servers almost 1:1 into temperature. During the hot months in summer, everyone has certainly already experienced sometimes the rising temperature in a room where even only a simple PC is operated and has wished for a computer system that behaves "neutral" to the generated warmth. Our datacenter holds way above 1.000 constantly operating server systems by now and directly related to this is the warm air exhaust as one can easily imagine.

Even though our present air conditioning could still cope with many more servers, as it had been originally built to handle up to 1500 servers, we intentionally do not want to bring our recent climate control to it's limit. Instead we are commited to guarantee a failure free system operation around the clock for our clients.

This stands to reason that we will launch the second level of our air conditioning, as scheduled during the next 12 weeks and thereby upgrade the present cooling capacity by another 150%. Afterwards we can set up 2.000 additional dedicated machines while the temperature will remain 'cool' in the true meaning of this word.

Just like before, with our first level of climate control, also this second one will be technology- and enegywise top of the notch. With the assistance of free cooling systems mounted on the rooftop of the building, this new extension will equally use the outside air for cooling down the data center. The water temperatures are being therefore adjusted to a level, that even in summer the free cooling remains active. It will therefore not be necessary, during many times, to engage the power consuming mechanical cooling system. Our new climate control will be working extremely efficient in regards to energy. This not only protects the environment and saves costs, but is also beneficiary to our clients as we directly pass on those savings to them. A 24/7 surveillance of all systems via webserver, smoke detector, water intrusion detection and the like is standard of course.

For the expansion of our cooling capacities we will be setting up a completely isolated cooling circuit, which is operating totally independant from the primary one. This means that we do not only lay all the pipes, but all the electrical wiring another time around. Additionally, recirculating air coolers within the data center itself and a new cold water aggregate on the roof of the building will be installed. The result: Two independent, redundant climate systems by all means.In the most unlikely event that one system should fail - regardless why and which part of it - the other one takes over and keeps on running.

That is how we define high availability and a maximum of safety for the servers of our clients. This upgrade requires again a substantial financial investment which we however pleasantly accept to the benefit of our customers. At the same time, the prices of our servers and services are not raised by a single cent.

Update: Fiber cable (colt) mounted

I already wrote about our new 10 Gbit/s fiber connection via Colt to Telia Sonera which is going to be available at the 1st of July in our datacenter. Today some technicians instructed by Colt appeared and - after having passed our safety steps before entering the datacenter area - mounted the Colt fiber cable through the building into the Core Rack of our datacenter, next to our Cisco Routing equipment.  I have made a photo of the new fiber patchpanel to illustrate this:

Now the physical connection has been completed and the red (or is it orange?) cable is waiting to be connected to our router. There are only a few steps left until this will be completed, too.  Afterwards, Giga-Hosting and Giga-International will be completely "multi-homed" by different fiber cables led from different directions into the building. This is a great benefit for our customers and although we never had network problems since we moved into our new datacenter one year ago our network will be even more secure and even more stable afterwards.
