Colocation: What it is, How it works



Colocation - also colocated, collocated, collocation - is the placement of your own server(s) and/or your network equipment in an Internet data center (or colocation facility) along with hundreds of others servers. The Data Center is managed to provide reliable networking, power, connectivity and security services. You can access you machines by going to the facility at any time.

Colocation has several advantages for the customer

  • High speed connections via multiple carriers to prevent downtime
  • Guaranteed power supply incorporating battery UPS for short term combined with an onsite diesel generator and sub-station for extended outages
  • Servers can be installed and online immediately
  • Additional servers can be easily added as your needs grow
  • All services are monitored by network engineers 24 x 7
  • Colocation facility uses electronic access security & security guards to protect your equipment

    Colocation Cost

    Colocation requires an initial investment for the server, plus ongoing hardware and software maintenance. In addition, each Month, you have to pay for the space (Rack Space) and the bandwidth used by your server(s).

    Space used by your server(s)

    Your server(s) will be mounted in the rack. A rack is a metal framework that houses electronic equipment and usually contains bays designed to piece of equipment like a server.

    The space used by your server(s) is measured in Rack Units (RU or "U-Space"). This is the unit of measurement used for defining the vertical space used. A 'U' is equivalent to 1.75 inches (4.45cm).

  • 1U Server= 1.75" of Vertical Rack Space
  • 2U = 3.5" of Vertical Rack Space
  • 4U = 7.00" of Vertical Rack Space
  • A full rack can contains 40 to 42U
  • 1/4 Rack=10U (10 servers of 1U)
  • Half rack =20 U (20 Servers of 1U)

    So, if you have to buy your own server you have to choose a rackmount server (or rack mounted server) it has been designed to live on a rack.

    What is Bandwidth ?

    Bandwidth is a measure of data transfer. Computer data is fundamentally measured in bits, and bytes. Understanding the units of measure is necessary before you can do anything else. A Byte is simply 8 bits. In the world of computers measurements are conveniently represented by powers of two, while in the real world powers of ten are prevalent. This caused the confusing definition of "Kilobyte" to mean 1024 bytes instead of 1000 bytes as you might expect. Compounding the confusion, a Megabyte" is 1024 Kilobytes, or 1048576 bytes. A Gigabyte is 1024 Megabytes, or 1048576 Kilobytes, or 106954752 bytes. The number of bits or bytes per unit of time is referred to as bandwidth. Thus you see numbers such as 1.5Mbps (1,500,000 bits per second) 28.8Kb/s (28.8 Thousand bits per second) or 3GB/month (Three Gigabytes per month.)

    The first lesson of understanding bandwidth is not to confuse Bits and Bytes. If you do, your numbers will be off by a factor of 8, which is usually pretty significant. Many vendors quote numbers in bits, because the result is 8 times larger and makes things look more impressve. Usually a lower-case 'b' indicates bit, and an upper case 'B' indicates byte, but you can't always rely upon that.

    The second lesson is to understand that 'K' technically doesn't mean 1000, but everyone usually acts like it does. Minor discrepencies in numbers can usually be accounted for by this assumption. Unless you're talking about huge amounts of data, it's unlikely to make much difference. (less than 10% for even a Terabyte)

    How is measured the monthly bandwidth usage

    There are different schemes for paying for bandwidth.

    I Real Data transfer ( Burstable Bandwidth)

    Your host will provide you a graph ( usually MRTG graph) wich shows average bandwidth incoming and outgoing traffic in real-time. On this graph you will read several data as the Monthly Average Out and the Monthly average In.

    To measure the real Monthly Data transfer used you have to use use the following equation:

  • Monthly Average Out + Monthly Average In / 8 bits x 60 seconds x 60 minutes x 24 hours x 30.5 days = total bandwidth used for the month.

    Note, some host providers counts only the Monthly Average IN or OUT. With them, you can save a lot of money.

    Sample of Measure of the real Monthly data transfer

  • Mrtg Graphs shows : Monthly average IN + OUT =1024 Kbps = 1 Mbps
  • 1024 kbps/8*60*60*24*30.5= 337305600 Kilobytes /1048576= 321 GB.

    Find here some conversion:

  • 1Mbps = 320GB
  • 10Mbps= 3200GB
  • 20Mbps =6400GB
  • 50Mbps=16000GB
  • 100Mbps =32000GB

    II Capped Bandwidth ( also unlimited transfer)

    Another common system is capped bandwidth, is simply to pay for the bandwidth that's available. For example, you might get 1 Mbps of bandwidth capped, and you can use all of it or none of it and pay the same amount. The network administrator will program the router to cap your usage at that amount.

    III The 95th percentile

    95th Percentile is a method of measuring bandwidth that bases your bill on peak utilization. Your bandwidth is measured from the switch or router and recorded in a log file. At the end of the month, your usage statistics are sorted, and the top 5%, or 37 hours, of data is thrown away, and that next measurement becomes your 'utilization' for the month.

    So, if you had a great weekend promoting your site, and used 3mb/sec for two days, you would be billed for the 3mb/sec rate -- potentially much more expensive than your average bandwidth utilization or actual utilization.
