Whitepaper: Maintaining application performance with all-flash arrays and storage QOS

Shared infrastructure, both in enterprises and cloud providers, is required in order to achieve the most efficient utilisation of resources. With solid state storage systems now able to deliver significant performance, these systems are often used to consolidate hundreds of virtualised applications. However, these shared environments present significant challenges for IT and application owners.

Maintaining specific performance levels for applications has always been challenging when using shared infrastructure. In particular, storage consolidation and the move to virtualised applications have made maintaining storage performance particularly difficult. Enterprise customers need the ability to manage performance, while cloud and other service providers require these capabilities in order to deliver differentiated service levels. Centralised IT and cloud service operations have additional considerations, requiring predictable levels of service consistently, with 24x7 operations. With unpredictable workloads and continual operations, scheduling reduced workloads for data protection or backup operations is not possible. Thus, modern operations must be able to support multiple primary workloads, with additional data protection operations, while still meeting all performance needs.

Traditional data centre class storage systems have provided quality of service (QOS) capabilities; however, these systems are unable to meet application price performance requirements, particularly in virtualised and cloud computing environments where cost is a significant consideration. In IT environments supporting virtual computing and cloud infrastructures, QOS controls must be both flexible and scalable in order to support management domains.
