Storage QoS: where HP 3PAR StoreServ beats the competition


MM2.jpgBy Matthew Morrissey, 3PAR Product Marketing Manager, HP Storage


QoS defined: with an eye to controlling service metrics requirements

Quality of Service (QoS) is an essential component in delivering modern, highly scalable, multi-tenant storage architectures. The use of QoS moves advanced storage systems away from the legacy approach of delivering I/O requests with “best effort” in mind. It tackles the problems of the “noisy neighbor,” delivering predictable tiered service levels and managing “burst I/O” irrespective of other users of a shared system.


Mature QoS solutions meet the requirements of controlling service metrics such as throughput, bandwidth and latency without requiring the system administrator to manually balance physical resources. These capabilities eliminate the last barrier to consolidation by allowing you to deliver assured QoS levels without having to physically partition resources or maintain discreet storage silos.


QoS compared: HP 3PAR StoreServ, EMC and NetApp

EdisonGroup_paper.jpgEdison Group recently produced a study comparing Quality of Service features from HP 3PAR StoreServ, EMC and NetApp. The study found: when deployed with hard disk drives, solid-state drives, or a combination of both media – only 3PAR Priority Optimization for the entire 3PAR StoreServ Storage portfolio delivers on all QoS requirements with a consistent approach and results. This enables you to deliver I/O requests based on service metrics. Other offerings in the marketplace implement QoS at the hardware layer (for example, assigning fixed amounts of cache to a volume) that is not measurable in terms of application performance.

See why Edison believes HP 3PAR StoreServ Priority Optimization offers the most mature and complete Quality of Service implementation.


There's also an HP technical white paper that dives into HP 3PAR Priority Optimization that I recommend as another resource to learn more.


Let's go deeper!

You'll want to read this Forrester white paper, "Top Storage Capabilities Needed in 2014 to Reduce Risk and Maximize Performance" .  Here's a summary of the paper: the burden of storage continues to get heavier for organizations that wrestle with fast growth and are highly sensitive to outages and data loss. Some firms are tempted to maintain the status quo and simply add capacity to meet their near-term storage challenges. But technology innovations that can reshape a company’s infrastructure.
