Unified API provides a single interface to discover, search, inventory, configure, provision, update, and diagnose the Composable Infrastructure. A single line of code enables full infrastructure programmability and can provision the infrastructure required for an application.

For resolving latency issues on a Nimble CS3000 storage system, particularly for a high-demand application like a 2TB ERP database, the best approach is to add additional SSD drives to the system as cache and PIN the volume. This ensures that the entire database or frequently accessed parts of it are always stored in the fastest storage tier (SSD), significantly reducing latency and improving overall performance for the ERP database.

The HPE 3PAR SSMC (StoreServ Management Console) System Reporter is the tool that should be used to generate and schedule high-resolution performance reports, including service time and I/O workload information. By configuring System Reporter to send daily email reports, both you and the customer can monitor the impact of changes made to the Adaptive Optimization (AO) configuration. This ensures that any latency issues or performance improvements are documented and can be analyzed regularly.
