Data Center Redundancy Strategies from a Trusted Alexandria Data Center Company

Business systems need to be always-on, available 24/7, and demonstrate consistent experiences and reliability. Moreover, outages cost thousands per minute and 94% of companies that suffer a catastrophic data loss do not survive. Data center redundancy is absolutely crucial to operational excellence and business sustainability.

Establishing redundancy across an entire data center operations requires a two-prong approach that involves both:

• Physical redundancy measures
• Strategic redundancy process

“To prevent business-crippling outages from occurring and to build systems that keep users engaged, redundancy must be built in as many layers of a company’s data center operations as possible.” says John Unger, President of Vaultas.

“Having IT infrastructures that provide next-level redundancy is as equally important as having physical redundancy in your data centers.”

What is IT Redundancy and Why It’s Essential for Businesses with Alexandria Data Center

IT redundancy involves building measures and processes into a business’s IT infrastructure that prevent business operations from being disrupted in the event something goes wrong within its data center operations. It involves designing systems with duplicate components, ensuring that if one fails, a backup is immediately available.

For example, if a primary server handling customer transactions fails, a secondary server is pre-configured and ready to go into service instantly and takes over, preventing disruptions and safeguarding against revenue loss. Or, if a data center experiences a power outage due to severe weather, the data center has UPS and Generator backup power to take over for the lost power.

Finally, if a data center were to fail due to a catastrophic event, you will want to have a back up at another data center to seamlessly pick up the load, maintaining uninterrupted service and data accessibility 24 x 7 x 365 is accomplished through “Redundancy”.

Redundancy is Crucial for Businesses

In an era where downtime can lead to substantial financial loss and reputational damage, having redundant systems ensures continuous service availability, preserving customer trust and business continuity and should be part of creating your resilient infrastructure.

Physical redundancy is vital for businesses because it directly influences their ability to operate without interruption, safeguarding against failures caused by hardware malfunctions, software bugs, severe weather events, and human errors.

A classic example of why redundancy matters is the 2007 LAX outage that lasted 9 hours and stranded 17 000 international passengers. The cause? A malfunctioning network interface card on a single desktop computer.

Redundant IT infrastructures focus on creating an IT ecosystem that safeguards a business against disruptions and data loss, which can be catastrophic. Use of multiple clouds, colocation, and on-premise backup servers are examples of measures used to build redundant infrastructures.

A key focus is to have copies of data stored in multiple locations—both geographically and digitally. This gives businesses layers of protection against natural disasters, cyberattacks that can happen every 39 seconds, and other potentially disruptive events, ensuring long-term resilience and compliance with industry regulations.

What is Data Center Redundancy?

Redundancy in a data center involves implementing robust physical measures to ensure operational continuity. This involves following data center redundancy best practices that include multiple power sources, backup generators, and redundant cooling systems. Other features include disaster-resistant buildings, and a myriad of security measures.

A data center’s redundancy capability is expressed in N levels. These include:

• N: The basic data center redundancy level. This is where each component needed to operate is available without any spares. This setup provides the minimum level of redundancy and operates under the assumption that no single component will fail.
• N+1 redundancy data centers offer additional redundancy levels by providing one extra component (like a power supply or server) beyond what is necessary for operation. This ensures that if a component fails, the system can continue functioning without interruption until the failed component is repaired or replaced.
• 2N: This level doubles the infrastructure required to operate by having two independent systems with full capability to handle the entire load independently. If one system fails, the other can seamlessly take over all operations, offering a higher degree of fault tolerance and availability.
• 2N+1: Enhances the 2N setup by adding an extra component to the already doubled infrastructure, ensuring even greater reliability. This setup not only has two full systems capable of operating independently but also includes an additional spare part or system.

Another way of expressing redundancy is with the data center redundancy tiers classification system developed by the Uptime Institute. The system has four tiers and outlines the different physical measures a data center must have to meet each tier’s requirements and provide minimum uptime guarantees to be leveraged at the different levels.

• Tier 1 Data Center Uptime: 99. 671% or less than 28.8 hours of downtime per year
• Tier 2 Data Center Uptime: 99.741% or less than 22 hours of downtime per year
• Tier 3 Data Center Uptime: 99. 982% or less than 1.6 hours of downtime per year
• Tier 4 Data Center Uptime: 99. 995% or less than 26.3 minutes of downtime per year

Strategic Redundancy in IT Infrastructure Design

A business’s IT infrastructure is no longer housed in a single operational building or data center. Today’s infrastructures are increasingly being spread across multiple physical locations in various geographical locations.

This is to ensure businesses reach their customers effectively and so business continuity can be easily maintained when faced with disruptions. Strategies that support this often include colocation and hybrid infrastructure designs.

“Think of redundancy in IT like having backup plans for everything: it’s there to keep things running smoothly even if something goes wrong. By having extra systems and fail-safe measures in place, redundancy helps prevent crashes and ensures that important services stay up and running, which is crucial for businesses to keep things moving,” said Joe Unger, VP of Business Development at Vaultas.

Colocation

Colocation is a service where businesses outsource some (or all) of their data center operations to established, off-site data centers. How colocation builds redundancy into their infrastructures is by providing a minimum of an N+1 layer of physical redundancy of all equipment that supports their facilities.

Physical Infrastructure: Colocation centers provide robust physical infrastructure, including concrete and steel reinforced buildings, redundant power systems, (N+1 UPS systems and backup generators),N+1 cooling systems, and access to many different network connections providing redundancies in networking as well. These facilities are designed to ensure there is no single point of failure, so if one component fails, another immediately takes over, minimizing downtime.

Network Redundancy: Colocation data centers typically have multiple network providers and high-bandwidth options, allowing for data traffic to be rerouted quickly in case one network provider experiences a failure. This setup ensures continuous network availability and access to multiple network resources.

Geographical Diversity: Colocation allows businesses to distribute their systems, data, and applications across multiple geographic locations via redundant network connections. This geographical spread provides a layer of protection against regional outages caused by natural disasters, power failures, or other localized incidents. If one location is impacted, other sites can continue to operate without interruption.

Scalability and Flexibility: As businesses grow, their data needs can change. Colocation centers offer the flexibility to scale IT operations quickly and on an as needed basis, without the need for significant capital investment in physical infrastructure. This flexibility is crucial for maintaining scalability and redundancy as it allows businesses to adjust their infrastructure capacity based on current needs and work loads.

Hybrid IT Infrastructure

Hybrid infrastructure can provide a strategic blend of different IT environments. Today’s IT environments require companies to use multiple cloud based applications and solutions, each with its own set of redundancy benefits. 80% of companies in 2022 were found to have adopted a hybrid IT approach, incorporating a blend of private and public clouds as well as on-premise/colocation solutions. This is the future of IT as major application providers require you to use their cloud infrastructure in order to use their software. Thus the NEED for Hybrid Colocation solutions like Vaultas offers.

It combines on-premises, colocation, and cloud environments, and supports redundancy in several key ways:

Diversification of Resources: Hybrid infrastructures allow organizations to spread their IT resources across multiple environments. For instance, critical applications can be hosted in the cloud, while backup or redundant instances can be managed on-premise or in a Colocation data center like Vaultas.

This diversification means that if one environment experiences an outage, or is compromised, the other environments can take over, maintaining service continuity.

Flexibility and Scalability: Hybrid setups enable businesses to scale their resources up or down based on demand without being limited by physical infrastructure constraints. Excellent for managing IT costs based on current economic drivers up or down.

For example, during peak loads, additional resources from the cloud can be leveraged to handle the increase in demand, and similarly scaled down when the demand drops. This elasticity helps ensure that there are always sufficient resources available to handle the workload, and enhances overall redundancy.
