Abstract
The amount of data managed by organisations continues to grow relentlessly. Driven by the high costs of maintaining multiple local storage systems, there is a well established trend towards storage consolidation using multi-tier Virtualised Storage Systems (VSSs). At the same time, storage infrastructures are increasingly subject to stringent Quality of Service (QoS) demands. Within a VSS, it is challenging to match desired QoS with delivered QoS, considering the latter can vary dramatically both across and within tiers. Manual efforts to achieve this match require extensive and ongoing human intervention.
组织管理的数据量持续增长。由于维护多个本地存储系统的高成本，使用多层虚拟化存储系统(vss)进行存储整合已成为一种趋势。同时，存储基础设施对QoS (Quality of Service)的要求也越来越高。在VSS中，将期望的QoS与交付的QoS匹配是具有挑战性的，因为后者在层之间和层内都可能发生巨大变化。手动实现这种匹配需要广泛和持续的人工干预。
