Guaranteeing Storage Performance: Everything you need to know about storage Quality of Service in a next generation data center

The increasing demands and velocity of change enacted on enterprise IT organizations and service providers today is unrelenting. Users are looking to deploy more applications faster, and for the resources that support those applications to be more agile and adaptive to changing demands. To make things even more challenging for IT, the world’s largest public cloud providers have set the benchmark for what it means to deliver Infrastructure as a Service (IaaS) at scale. The answer for staying competitive in this new landscape is guaranteeing predictable application performance with storage Quality of Service (QoS).

Only true QoS enables infrastructures capable of delivering compute, networking, and storage predictably and on demand — allowing IT to dramatically raise operational efficiencies, innovate more quickly, and enable them to respond to application and business challenges faster than ever before.

At the heart of delivering infrastructure on demand, and as a service, is the concept of multi-tenancy, in which multiple applications and/or customers reside within the same storage infrastructure. While at first glance the opportunity to run a broad array of applications within a single system may sound appealing, the reality for today’s IT managers is very different. When a large number of performance-sensitive applications are consolidated onto a single platform (traditional or flash), “noisy neighbor” applications show up and cause resource contention, unpredictable application performance, and unhappy customers.

So it begs two simple questions:

  1. How do you transition from a siloed IT environment to a single infrastructure capable of handling a broad set of applications without sacrificing performance, while at the same time being more agile, automated, and predictable?

  2. What storage capabilities are required to do so?
