You can optimize copy operations and system performance by carefully planning bandwidth, number of data paths, number of host interface paths, and number of ports. Check with customer support for more information.
- Analyze write-workload. You need to collect workload data (MB/s and IOPS) and analyze your workload to determine the following parameters:
- Amount of bandwidth
- Number of data paths
- Number of host interface paths
- Number of ports used for TrueCopy operations on the primary and secondary systems
Thorough analysis and careful planning of these key parameters can enable your system to operate free of bottlenecks under all workload conditions.
- If you are setting up TrueCopy for disaster recovery, make sure that secondary systems are attached to a host server to enable both the reporting of sense information and the transfer of host failover information. If the secondary site is unattended by a host, you must attach the secondary storage systems to a host server at the primary site so that the system administrator can monitor conditions at the secondary site.
