Or the combination of hypervisor (front end) and the storage subsystem The VMAX driver only supports the storage subsystem (back end) QoS enforcement in cinder is doneĮither at the hypervisor (front end), the storage subsystem (back end), Each volume type is tied to specific QoS attributes The cinder QoS offers similarįunctionality based on volume type setting limits on host storage bandwidth Network administrators set limitations on certain networks Quality of service(QoS) has traditionally been associated with networkīandwidth usage. Tag means the latency range will be the widest for its SLO type. Range is reduced due to the added information. When a workload type is added, the latency (storage groups not associated with any service level).

Tag means that non FAST storage groups will be created instead ServiceLevel VMAX All Flash and Hybrid only. Pool is the bind pool to be used with the FAST policy. For back ends exposing FAST policy automated tiering, the For back ends not using FASTĪutomated tiering, the pool is a single pool that has been created by theĪdministrator. Pool Unique pool name within a given array. Given back end), as appropriate for the configured driver (iSCSI or FC). The PortGroups set contains either all FC or all iSCSI port groups (for a VMAX driver, the port group is chosen randomly from the PortGroup list, toĮvenly distribute load across the set of groups provided. When a dynamic masking view is created by the PortGroups can contain one or more port groups ofĮither iSCSI or FC ports. Switches) as to ensure adequate bandwidth and failure protection for the Have sufficient number and distribution of ports (across directors and PortGroups Supplies the names of VMAX port groups that have been pre-configured toĮxpose volumes managed by this backend. EcomUserName and EcomPassword Credentials for the ECOM server. EcomServerPort Port number of the ECOM server which is packaged with SMI-S. EcomServerIp IP address of the ECOM server which is packaged with SMI-S. Support DSS_REP, DSS, OLTP_REP, OLTP, and NONE workloads. VMAX All Flash supports Diamond and NONE. VMAX Hybrid supports Optimized, Diamond, Platinum, Gold, Silver, Bronze, and Once the nf and EMC-specific configuration files have beenĬreated, openstack commands need to be issued in order to create andĪssociate OpenStack volume types with the declared volume_backend_names: Volume_backend_name, and the name of the EMC-specific configuration fileĬontaining additional settings.
