Benefits Cross Platform Migration

Migrating Data Cross Platform

• Avoids network bottleneck

• Eliminate the need for double storage

• Large datasets can be migrated in minutes, not hours, or days

• All major Unix and Linux versions are supported

• Physical to physical and physical to virtual

Cross Array Migration Benefits

• Online and centrally managed

• Any to Any Storage Transformation

• All major Unix and Linux version supported

• Storage Layer mirroring

• Wizard based migration

• SmartMove Migration


Migrations Between Datacenters

Datacenter Migration Benefits

• Any to Any Storage Transformation

• All major Unix and Linux versions supported

Automate High Availability and Disaster Recovery

Metropolitan HA (Stretch Cluster)

Wide-Area DR (Global Cluster)

Local HA • Recover faster

• Reduce reliance on personnel during an incident

• Reduce operator error

• Provide comprehensive data and application availability

• Simplify by using a single solution for:

– Local HA

– Campus/Metro DR

– Global DR

CODM Advisor Identify benefit from CODM

• Set policies to determine metrics for performance analysis

• Gather statistics from Oracle Automatic Workload Repository report

• Allow DBAs to enable/disable Cached ODM for selected files

Reduce Total Cost of Ownership with Storage Tiering


TABLE CALL_DETAILS

FILE 1 FILE 2 FILE 3

FC SSD

• SmartTier allows DBAs to move any

TABLE or OBJECT from and to any tier of storage, non disruptively

• Move Oracle objects WHEN and WHERE it makes sense based on your business processes

• Stage data on SSD in anticipation of time sensitive processing

• Archive to cheap storage once you know you are done
