EVA 2: Business Continuity and Availability

Special notes

This course replaces UC423S effective on 3/3/09

Course overview

This 3-day instructor-led training course introduces the student to the HP StorageWorks Enterprise Virtual Array data replication environment. That environment includes both local replication (Business Copy Enterprise Virtual Array [BC EVA]) and remote replication (Continuous Access Enterprise Virtual Array) solutions. The focus of this course, however, is the remote replication capability represented by Continuous Access EVA. Also discussed is the Replication Solutions Manager (RSM) software application.

Prerequisites

Students should successfully complete the following course prior to attending this course:

• HP StorageWorks Enterprise Virtual Array 4-day (UC420S)
• HP StorageWorks Enterprise virtual Array 5-day (U4879S)
• It is preferred that students have a working knowledge of at least one of the supported operating systems

Audience

System Administrators responsible for managing the many types of copy sets found in the Enterprise Virtual Array (EVA) environment.
