Managing for highly available implementations
Establishing a highly available network includes identifying critical components, creating redundancy for these components, and ensuring automatic failover to the secondary component if the active component fails. Critical components include:
-
Database
-
Provisioning Servers
-
vDisks and storage
Provisioning Services provides several options to consider when configuring for a highly available implementation, including:
-
Database
-
Offline Database Support, which allows Provisioning Servers to use a snapshot of the database if the connection to the database is lost.
-
-
Provisioning Servers
-
Provisioning Server Failover. If a server becomes unavailable, another server within the site can provide active target devices with the vDisk.
-
Managing Load Balancing Across Servers. You can load balance between Provisioning Servers to prevent overload and to allow server capacity to be used more effectively and efficiently.
