The world of IT is undergoing a digital transformation. Applications are growing fast, and so are the users consuming them. These applications are everywhere—in the datacenter, on virtual and/or microservices platforms, in the cloud, and as SaaS. More and more apps are now being moved out of datacenters to a cloud-based infrastructure.
In order for an optimized and secure delivery of these applications, IT needs specific network appliances called Application Delivery Controllers (ADCs). These ADCs come in hardware, virtual, and containerized form factors, and are sized by Network Administrators based on the current and future usage of applications. The challenge with this is that it’s hard to foresee sizing or scalability requirements for these ADCs since users are constantly increasing, and applications are consistently evolving, as well as moving out of datacenters.
Complicating matters, most ADCs are fixed-capacity network appliances that provide zero or minimum expansion capability

Business evolution and technology advancements during the last decade have driven a sea change in the way data centers are funded, organized, and managed. Enterprises are now focusing on a profound digital transformation which is a continuous adjustment of technology management resources to deliver business results, guided by rapid review of desired outcomes related to end clients, resources, and budget constraints. These IT transitions are very much part of the competitive landscape, and executed correctly, they become competitive differentiators and enable bottom line growth. These outcomes are driving data centers to virtualization, service-oriented architectures, increased cybersecurity, “big data,” and “cloud,” to name a few of the key factors. This is completely rethinking and retooling the way enterprises handle the applications, data, security, and access that constitute their critical IT resources. In essence, cloud is the new IT.

F5 pioneered the concept of breaking up data center virtualization technologies into eight unique categories within the data center. Any virtualization products or technologies implemented in the data center will fall into one of these eight categories.
To accommodate increasingly dense technology environments, increasingly critical business applications, and increasingly stringent service level demands, data centers are typically engineered to deliver the highest-affordable availability levels facility-wide. Within this monolithic design approach, the same levels of mechanical, electrical, and IT infrastructure are installed to support systems and applications regardless of their criticality or business risk if unplanned downtime occurs. Typically, high redundancy designs are deployed in order to provide for all eventualities. The result, in many instances, is to unnecessarily drive up both upfront construction or retro-fitting costs and ongoing operating expenses.
When Alcatel bought out Lucent at the end of 2006, the two companies had already begun planning data center consolidations of their own, but the merger changed all that. As it turns out, the merged company created a plan to consolidate 25 data centers and 125 server rooms down to six data centers and just a few server rooms. This change has presented challenges, especially in terms of arranging downtime and dealing with employees' attachment to their servers and applications, but the company is on pace to meet it’s goal of reducing IT operational cost by 25% over three years.
Today’s enterprises face new requirements for their datacenter
and cloud architectures, from keeping pace cost-effectively with
fast-growing traffic to ensuring optimal application
performance no matter how quickly business needs or the
enterprise environment evolve. At the same time, IT must reduce
costs and datacenter sprawl, ensure security and uptime, and
prepare for a new generation of cloud computing initiatives.
While many Application Delivery Controller (ADC) solutions
promise to meet demanding customer needs, the reality often
falls short. Taking a closer look at the available options and how
they measure up against the criteria that matter most, it
becomes clear that NetScaler beats the competition—providing
better performance and scalability than F5 Networks, Inc.

This paper discusses how Nimble Storage’s flash-optimized architecture is engineered to accelerate applications, scale performance and capacity, protect data, and make IT more productive and empowered.
Data center administrators face a significant challenge: They need to secure the data center without compromising the performance and functionality that new data center environments enable. Many are looking to secure the data center using solutions designed for the Internet edge, but these solutions are not enough. The data center has unique requirements around provisioning, performance, virtualization, applications, and traffic that Internet-edge security devices are simply not designed to address.

For many organizations, the wide area network (WAN) infrastructure that connects an enterprise’s remote and branch
offices has not changed for decades. Over the years, organizations consolidated many regional data centers into a few
highly available data center locations which meant that remote locations had to connect to centralized applications over
WANs and all internet traffic went through these data centers as well. This introduced bandwidth constraints and latency
issues. The development in WAN optimization provided incremental and measurable improvement in WAN performance
and provided some bandwidth cost containment. However, that technology typically was only deployed at the most
problematic sites that struggled to achieve acceptable levels of performance and user experience. It did not solve all the
issues with WAN connectivity.
WAN infrastructure planning was limited to increases in capacity that were met by provisioning additional carrier MPLS

Poor rack cable management has proven to many data center operators to be a source of downtime and frustration during moves, adds and changes. It can also lead to data transmission errors, safety hazards, poor cooling efficiency, and a negative overall look and feel of the data center. This paper discuses the benefits of effective rack cable management, provides guidance for cable management within IT racks including high density and networking IT racks, which will improve cable traceability and troubleshooting time while reducing the risk of human error.
Raising IT inlet temperatures is a common recommendation given to data center operators as a strategy to improve data center efficiency. While it is true that raising the temperature does result in more economizer hours, it does not always have a positive impact on the data center overall.
In this paper, we provide a cost (capex & energy) analysis of a data center to demonstrate the importance of evaluating the data center holistically, inclusive of the IT equipment energy. The impact of raising temperatures on server failures is also discussed.
As IT advances, organizations are adopting infrastructures that enhance agility and improve efficiency.
Data centers are evolving to a state that is almost unrecognizable from only a few years ago. Numerous forces, such as cloud computing and powerful orchestration solutions, are combining to fundamentally change data centers, making them more powerful, sophisticated, flexible and efficient. Many organizations are adopting a hybrid infrastructure data center model that combines a variety of technologies and methodologies, including virtualization, private clouds and other internal IT resources, along with external options such as hosting, colocation, Software as a Service (SaaS) applications and Infrastructure as a Service (IaaS) offerings.

Intelligent N+X Redundancy, Placement Affinities, & Future Proofing in the Virtualized Data Center
Virtualization brought about the ability to simplify business continuity management in IT. Workload portability and data replication capabilities mean that physical infrastructure failures no longer need impact application services, and they can rapidly be recovered even in the event of complete site failure.
However, Enterprises and Service Providers face new challenges ensuring they have enough compute capacity in their virtualized data centers to support their business continuity requirements, while at the same time not over provisioning infrastructure capacity resulting in unnecessary capital expenditure.

An Intelligent Roadmap for Capacity Planning
Many organizations apply overly simplistic principles to determine requirements for compute capacity in their virtualized data centers. These principles are based on a resource allocation model which takes the total amount of memory and CPU allocated to all virtual machines in a compute cluster, and assumes a defined level of over provisioning (e.g. 2:1, 4:1, 8:1, 12:1) in order to calculate the requirement for physical resources.
Often managed in spreadsheets or simple databases, and augmented by simple alert-based monitoring tools, the resource allocation model does not account for actual resource consumption driven by each application workload running in the operational environment, and inherently corrodes the level of efficiency that can be driven from the underlying infrastructure.
