Release Notes

6 Configuring Dell Storage Manager for High Availability | 3272-BP-DSM
1.4 Replication
If multiple Dell SC Series arrays are available in the environment, replicate the virtual machine and its
corresponding SQL database to a secondary array. The snapshot schedule determines when data is
transferred to the secondary array unless using synchronous replication or when replicating the active
snapshot asynchronously.
1.5 Redundant networking
To help ensure high uptime of the Data Collector, the LAN and SAN networks should follow standard industry
best practices for redundancy configuration, ensuring there are no single points of failure in either network.
Multipathing should be used on the SAN, while NIC teaming should be used on the LAN.
1.6 SQL database
While it is acceptable for pre-production to install the SQL database on the same virtual machine as the Data
Collector services, for production the SQL database should be stored on a separate virtual machine. In the
event the Data Collector virtual machine is lost, the VASA data will remain protected within the database
isolated in the other virtual machine.
1.7 Remote Data Collector
When using the remote Data Collector, it is important to remember that only saved restore points are mirrored
from the primary. Performance statistics, VASA data, vVol configuration data, and APM data are not copied
between the primary and secondary Data Collector databases.
