问题解答

AQoS 作为 Keystone 订阅要求的相关性:
  1.  服务级别:
  • Keystone 订阅附带预定义的服务级别,这些服务级别决定了存储卷的性能特征
    • 这些服务级别通过 AQoS 策略实施
  • 每个服务级别都有特定的性能/TiB 比率,AQoS 使用该比率根据卷大小调整配置的 IOPs 或吞吐量
  1.  性能管理:
  1.  不符合的卷:
  • 未分配给 Keystone 兼容 AQoS 策略的卷被视为不兼容
  • 未与 Keystone 兼容 AQoS 策略关联的任何卷将默认以最高签约服务级别计量
    • 不合规卷导致意外服务级别的消耗跟踪
    • 不合规卷可能导致不一致的性能和意外的节点利用率
  1.  消耗监控:
  • Active IQ Digital Advisor 提供消费报告,如果有 SLA/SLO,则提供 Keystone 订阅的性能报告
  • 报告包括承诺容量、已消费容量和突发容量的详细信息,帮助用户有效监控和管理其存储
