The Storage All-in-One ETL relies on the EMC SMI-S provider to collect capacity information about the Dell EMC VMAX systems. The Storage All-in-One ETL supports EMC VMAX3s models only.
Before configuring the Storage All-in-One ETL for TrueSight Capacity Optimization, you must ensure that the following requirements are met.
- TrueSight Capacity Optimization version must be supported by the ETL
- The Operating System of the ETL Engine running the ETL task must be a 64-bit version of Linux or Solaris
- It is recommended that the SCHEDULER_HEAP_SIZE environment on the ETL Engine running the ETL task be set to at least 2048m to avoid out-of-memory issues. This variable can be customized according to the amount of managed volumes and only if data collection problems occur.
EMC SMI-S Provider
Before configuring the Storage All-in-One ETL to collect EMC VMAX metrics, you must ensure that the following requirements are met:
- (Recommended) Use the SMI-S provider pre-installed in the Management Console. No further action is required.
- (Alternate option) Install EMC SMI-S Provider on a different system. In this case, version 8.0.3 or higher is required. If multiple VMAX systems are added to the same provider, the total number of volumes should not exceed 30,000 (hard limit of the provider is 50,000).
To manage EMC VMAX systems, the EMC SMI-S Provider requires at least one LUN to be mounted from each array to manage. These special LUNs are called "gatekeepers" and are used for the communication between the Symmetrix array and the SMI-S Provider (which does not have an IP address). EMC recommends having between 4 and 6 gatekeeper LUNs for each managed array. Increasing the number of gatekeepers dramatically improves the performance of the EMC SMI-S Provider.
