What Is Symmetrix Qos And How It Works?

Answer»

Quality of Service (QoS) allows more flexibility in managing Symmetrix system’s performance. By increasing the response time for specific COPY operations on selected devices, we can increase the overall performance of the other Symmetrix devices. 

  • The QoS (Quality of Service) feature allows us to ADJUST the data transfer PACE on specified devices, or devices in a DEVICE GROUP, for certain operations. 
  • The contention for cache access can be quality of service managed by the least recently used (LRU) ring partitions in the Symmetrix cache. 
  • We can control the priority service time of devices and control cache partitions for different device groupings.
