This section describes various supported standards associated with storage provisioning standards.
Storage resource pool (SRP) standards
PowerMax arrays are preconfigured from Dell EMC with one storage resource pool (SRP) containing all the storage available to the array.
Service level objectives (SLO) standards
During the preconfiguration process, all the drives are added to the disk groups based on the technology, capacity, and the required protection scheme. Each disk group has capacity that is partitioned for use by FBA devices, which are then added to the preconfigured SRP. The storage administrator can display the configuration of the SRP on the array and generate reports detailing the demand that storage groups or SLOs are placing on the SRP.
Fully Automated Storage Tiering (FAST) is controlled through predefined SLOs and Workloads.
Data reduction option standards
PowerMax delivers extreme efficiency with inline deduplication and compression, delivering up to 5:1 data reduction (average of 3:1), space efficient snaps, and thin provisioning. Its inline deduplication and compression have virtually zero impact on performance, and can be used with all data services, and are turned on/off by the application.
In a PowerMax system with Data Reduction hardware, by default, all storage groups have data reduction (compression and deduplication) enabled. This can be disabled based on the storage group from the element manager.
Data LUN standards
Data devices are thin devices (TDEV) of varying sizes depending on customer requirements.
By default, data devices have compression that is enabled at the storage group level. Disable compression if the application is not designed for compression.
The use of host LUN ID 0 is permitted for data LUNs when all hosts in the cluster are booting from local SD.
Storage masking standards
Storage is presented to the servers through a masking view.
Masking views consist of the following:
LUN mapping is automatically performed. To add more storage to a server, add another device to an existing storage group that is a part of a masking view.
