“Around the World in Eighty Days” – A classic adventure novel and one of Jules Verne’s most acclaimed works which describes how Phileas Fogg and his valet Passepartout attempt to circumnavigate the world in 80 days on a wager.
In the world of Business Critical Applications, especially IO intensive Oracle workloads, there is always a need for storage migration, based on the ever demanding workload profile. For example,
- Migrate storage from one Tier to another Tier within a storage array
- Migrate storage from one array to another array (within and between datacenters)
This approach is independent of whether those workloads are virtualized or not. The end goal is to ensure that the underlying storage architecture can provide and sustain the demanding needs of the Application.
This article describes how storage migration can be performed for Oracle database running on VMware vSphere, for any types of underlying storage. The migration is done using a combination of two key technologies, VMware Storage vMotion and Oracle Automatic Storage Management (ASM) depending on the database deployment model.
Before describing this technique, we first review some key ideas, including the deployment model of Oracle on vSphere and the fundamentals of Storage vMotion.
