In this month’s issue of Uptime, we’ll
expand on the concept of the active-active
data center by addressing some of the practical aspects of what it takes
to implement Continuous Availability (CA) in your business. The Active-Active Data Center, Part II Assessing Requirements for Continuous
Availability Last
month, we explained the emerging concept of the Active-Active Data Center (AADC), whose
purpose is to ensure business continuity, i.e., making certain that users
have continuous access to business-critical applications when outages of
vital systems, infrastructure, or power occur. To review, the main components
of the AADC include: ·
Business-critical application(s) that need continuous
availability ·
Physically separate IT locations or data centers ·
Redundant or virtualized computing resources and
applications ·
Redundant or virtualized storage systems ·
High-speed network technology to connect IT locations Cost vs. Requirements: Key Questions.
Not suprisingly, implementing a full AADC can be an expensive undertaking,
and not everyone can justify the investment needed to support shared
applications and placement of redundant infrastructure in separate locations.
However, implementation cost depends on a number of factors, not the least of
which are the separation distance and scale of data center resources. It is
thus important to determine where and
how much you need continuous availability of an application or service as
well as how much you can invest. To
help you, we suggest answering several key questions about your CA
requirements. ... Learn more >> Case Study: Multi-Site, High Availability Storage
