Neutral Datacenter - Rackspace

Summary

BGP4 routers, but often also server equipment, are generally colocated in computer racks in a carrier neutral datacenter. Such a datacenter not only provides optimal technical conditions but also an open market for services which results in maximum choice and lowest costs.

Open Peering does not provide rackspace itself. Most Carrier Neutral and Private datacenters in the Netherlands are shown on this NL Datacenters Google Map.

For maximum control and independence, Open Peering encourages parties to hire rackspace directly with a datacenter.

Description

What is a datacenter?

From Wikipedia: A datacenter is a facility used to house mission critical computer systems and associated components. It generally includes environmental controls (air conditioning, fire suppression, etc.), redundant/backup power supplies, redundant data communications connections and high security.

Carrier neutral datacenters

Officially a carrier neutral datacenter is a datacenter or colocation provider which only sells rackspace (incl. cooling, power, patchcables, etc.) and does not sell any form of bandwidth (e.g. transit, leased lines, dark fiber, VLAN's, peering, etc.).

Advantage of carrier neutral datacenters: open market

Carrier neutral datacenters are popular for multiple reasons:

  • A datacenter offers a controlled and secure environment for your equipment;
  • The datacenter/colocation provider does not have any bias towards any bandwidth provider or its own bandwidth services, so it will not try to push or oppose any specific service;
  • A datacenter functions as a very competitive marketplace, where multiple carriers and providers offer services, with choice, price, quality and flexibility advantages such competition offers;
  • Actually, having as many bandwidth providers as possible offering services locally available thereby become a marketing argument for a carrier neutral datacenters, so it will make an effort to increase to available options.
  • It is easy to switchover to a different provider or use multiple provider simultaneously in a datacenter because every other party is only one patchcable away;
  • Connections (patchcables) to carriers, providers and other parties can be made very easily and locally and without high long-range line costs.

Alternative: carrier private datacenter

Carrier-private datacenters also offer a controlled and secure environment, but generally do not allow other parties to offer bandwidth services their datacenter. Several even only offer colocation space as part of a package combined with their bandwidth services. This lack of competition reduces your options, choice and flexibility and often implies higher prices and lower quality.

Local carriers and Internet Exchanges

While selecting a datacenter to colocate your equipment it is important to ask the datacenter a list with which parties can locally provide transit capacity dark fibers to other locations, and which Internet Exchanges are locally available. The wealth in choice is one factor to take into account while selecting a datacenter.

What is rackspace?

Neutral colocation is generally offered in the form of rackspace per standardized 19 inch (428,6 mm) width computer rack.

Racks are generally rented as full height 73.5 inch (1.866,9 mm) rack, although the height is often calculated in subrack height Units or U (or rack unit or RU) of 1.75 inch (44,45 mm or 1 Russian vershok) each, giving 42U for a full height rack. Only a few datacenters rent partial racks, e.g. 1/3th (14U) or 1/4th (10U or 11U).

For a description of rackspace, also see Wikipedia.

Power and cooling

Most datacenters by default include two power strips in a rack which are secured at maximum 16 ampere (3.68 kilowatt) each. Many datacenters are dimensioned (build) in terms of power supply, emergency power and cooling at maximum 6 or 8 kilowatt of peak power consumption per rack. Some specialized datacenter can provide more power and cooling per rack.

In the rackprice generally a certain amount of power usage is included, for example 750 watt of permanent usage. Additional actual power usage is then billed in rear.

Patchcables

Datacenters can provide you with patchcables (e.g. UTP of fiber) to other parties in the same datacenters if you want to buy services from or sell services to other parties. Generally you are not allowed to run you own patchcables outside your own rack(s) because of security reasons. As there are overhead costs in the order and implementation, and the datacenter is also responsible for the quality of such cables after installation (you would call them if suddenly a cable does not work anymore), they will be substantially more expensive then just the raw cable price.
