Overview of
Server Priority Manager
Server Priority Manager allows you to set upper limits of the number of accesses from the server to storage system as well as the amount of data transfer. The upper limits are automatically disabled when the traffic between the server and storage system drops to user-defined levels.
By using Server Priority Manager, you can designate prioritized ports (for example, for production servers) and non-prioritized ports (for example, for development servers) and set upper limits and thresholds for the I/O activity of these ports to prioritize I/O operations to host servers requiring high-throughput I/O operations and prevent low-priority activities from negatively impacting high-priority activities.
Server Priority Manager supports Fibre Channel and iSCSI ports connected to open-systems hosts.
- iSCSI is only supported by CCI.
- SPM settings for iSCSI are available for LDEVs (not for ports).
