What is 2N redundancy?
Data centers are responsible for providing reliable and uninterrupted service for their customers around the clock. Unfortunately, these facilities are not infallible, and will always be susceptible to sudden power interruptions caused by weather, equipment failure, or sudden loss of municipal utilities. Since an unplanned outage can cost a company thousands or even millions of dollars in just a few minutes, many data centers offer multiple redundancies to prevent downtime.
Differences Between N+1, 2N, and 2N+1 Redundancy
Redundancy is the duplication of critical components of a system in order to provide a reliable backup in case of sudden failure. Data centers typically offer some form of redundancy for power, ensuring that the customer’s systems and devices will continue to operate with no noticeable effect to the user in an outage. However, not all data centers’ redundancy systems are equal.
The most common redundancy options in carrier facilities include:
- N+1. An N+1 system, also known as parallel redundancy, offers alternate, redundant components capable of handling 100 percent of the work needed to supply power to the customer’s equipment in case of component failure. Although this system contains redundant equipment, it may run on a shared main power source, so it is not a multi-independent, redundant system.
- 2N. A 2N system offers not one, but two uninterruptible alternate sources of power, offering seamless transitions between sources to continuously support the customer’s systems and equipment. In addition, the power sources are run separately, fully independent of each other, and go through a fully redundant path to eliminate any single points of failure. 2N systems are more reliable than N+1 systems because they offer at least two options for power in the event of failure, and can be regularly maintained, independently, and be used in the event of an extended power outage. Our Chantilly location offers 2N redundancy for data loss and downtime prevention.
- 2N+1. A 2N+1 configuration is the highest common tier of downtime prevention, and offers double the amount of power needed to run all client systems and devices. Additionally, each power source has separate, parallel, fully redundant components that can seamlessly power all necessary systems. All this means that if one component from one main power source used in the path fails, there is a backup component which can fully take on its role. This applies to all the components in each separate path from the main power sources.

How much space will I need in a colocation center?
You are ready to take your network to the next level, but you are not sure if a colocation provider is the best option. A colocation center can provide the power, cooling, bandwidth, and security necessary to store your servers and to keep your network up and running; however, there are monthly fees and rental costs needed to do so. As a result, you should carefully consider what your current needs, growth objectives, and the many options you have before you buy.
Types of Server Space Available in a Colocation Center
Data centers use a standardized measurement system when it comes to classifying server space. A (U) is the term used to measure storage space in racks, and the standard physical measurement of one rack unit (U) is 44.45 mm or 1.75 inches in height. From there, the amount of space used by a business can vary from inches to several thousand square feet depending on the scale and complexity of its network infrastructure.
Because space is offered in many different ways in a data center, below are some of the common rental options and their distinct advantages:
- Racks. In a colocation center, servers, network devices, and other hardware are mounted in a frame called a rack, making it easy to replace failed components. A standard rack is 19" wide, can accommodate several U in height, and each server rack shelf is positioned to provide optimized cooling. Data centers may allow customers to rent quarter, half, or full racks.
- Cabinets. A cabinet is an enclosure that acts as an outer shell or casing on a rack, which is locked and kept secure by the colocation provider. Fundamentally, all cabinets serve the same purpose. However, they can physically vary from being a separate enclosure installed around a rack, a larger enclosure meant to closely house multiple full racks, or even a “one-piece” design where the racks and the cabinet are one unit. Depending on security preferences, a customer may require an entire cabinet or share a single cabinet with other customers.
- Suites. Customers who require either higher security, extensive storage, or both may store their servers in large locked areas, commonly referred to as suites. A suite can be a large metal cage, a locked transparent room, or a secure confined area composed of privacy paneling. Suites house several or hundreds of cabinets depending on the desired square footage.
If you are anticipating rapid growth, it may be a good idea to invest in one of these storage options now to avoid the headaches of a massive data center migration later on. ATI offers secure server storage in one of our two DC-area data centers, both of which offer critical systems monitoring 24 hours a day, seven days a week, 365 days a year.

What cloud infrastructure plan is right for my business?
Once you have decided to invest in cloud computing, you will need to consider who will be responsible for hosting and maintaining your infrastructure. Large corporations may host their own platforms onsite, but this is often not feasible for small- or medium-sized businesses who do not want to devote a large portion of their resources to the IT department. Fortunately, third-party hosting services can take on as much or as little of the hosting and deployment necessary for your virtual environment.
Hosting Options for Cloud Computing
In most cases, businesses have three options for the deployment of a virtual platform: hosted infrastructure, hybrid infrastructure, and private infrastructure. Each one carries significant advantages, and can be scaled to meet the changing needs of business operations. The following is a brief overview:
- Hosted. A hosted cloud is owned and maintained by a service provider, with the hardware necessary to deploy the cloud in an offsite location. The business pays a monthly subscription fee, and the provider manages all of the applications and services.
- Hybrid. In a hybrid system, part of the infrastructure is hosted by a provider and part is hosted by the business. This system can involve many different combinations of solutions depending on the individual needs of each business. One of the benefits of a hybrid solution is that it allows companies to migrate into the cloud slowly, keeping sensitive systems onsite and using hosted clouds for less critical applications.
- Private. A private infrastructure is optimal for businesses who want to keep their servers and equipment onsite. The hardware is kept on the company’s premises, and the service provider is responsible for deploying and maintaining the cloud platform.
Many different factors can impact the choice of an infrastructure plan, including the type of industry, client base, and scale of operations. The professionals at ATI can evaluate your needs and help you determine which cloud computing plan is ideal for you.

What is patch management?
Patch management consists of grading new patches, testing them, and pushing them out. Patching plays a crucial part in businesses staying up-to-date with the newest versions of all the software they use on a day-to-day basis. Patching can correct known issues without installing new programs from square one. The system will remain secure and navigable without any disruption to the user when patches are implemented correctly.
Importance of Patch Management for Businesses
A patch is a piece of code that is created to be integrated into an existing software program. Software providers often release patches as new “updates” or “versions” which can improve functionality, performance, provide bug fixes, and prevent security breaches. Installing a Windows update or upgrading to the newest version of an iPhone app are examples of patch deployment. Without good patch management, a company could have a vulnerability in its software that a hacker could take advantage of—which could lead to stealing private information or bringing down the entire system.
Software developers will typically release new patches when:
- The developer has received reports of successful hacking in one of their applications
- The developer’s coding and testing team discovered a glitch before it could be exploited
- The developer has found a better way to implement or strengthen security
- The developer has improved user interface on one or more applications
Software and applications cannot exist in a vacuum. They will need to be updated regularly—in most cases, every few weeks—in order to function as intended. As businesses may neglect to install patches or fail to identify weaknesses in their systems, patch management is a necessary part of any IT service.
