Database Reference
In-Depth Information
It is import to remember during this phase to fully understand the capabilities of a
virtualized infrastructure and look for ways to leverage those capabilities to better meet
the business requirements around high availability, service-level agreements, and
database recoverability. Do not just replicate the way you do things today on a
virtualized infrastructure; instead, make sure you fully leverage the capabilities of the
virtualized infrastructure.
Work with your stakeholders to understand what is an acceptable database outage
window for the migration to the virtualized infrastructure.
Keep in mind during requirements gathering that you will be doing a database migration
as part of the implementation. For this migration, it is important that you determine when
the database can be down and for how long. The requirements you gather for this one-
time migration will help you determine an appropriate strategy for migrating the
database.
Phase 1: Requirements Gathering (Business and IT)
SLAs, RPOs, RTOs
Business requirements
Determine acceptable database outage for migration
Phase 2: Discovery
Baseline the current vSphere environment
Baseline the current database workloads
Compute requirements, memory, disk, and network
Assess the current physical infrastructure
Phase 2.1: Database Consolidations
License considerations
Phase 3: Infrastructure Adjustments
System configuration
Load balance environment
Phase 4: Validation and Testing
Load-test the environment
Validate failover/HA options
Phase 5: Migration and Deployment
Physical-to-virtual conversions
Deployment plan
Database migration plan
Backup/restores
