IBM SAN Volume Controller Enhanced Stretched Cluster with VMware
by Angelo Bernasconi, Ole Rasmussen, Jon Tate
Overview
This IBM® Redbooks® publication describes the IBM
storage area network (SAN) and IBM
SAN Volume Controller enhanced stretched cluster configuration when
combined with
VMware. We describe guidelines, settings, and implementation steps
necessary to achieve a
satisfactory implementation.
Business continuity and continuous availability of applications are
among the top
requirements for many organizations today. Advances in
virtualization, storage, and
networking make enhanced business continuity possible. Information
technology solutions
can now be designed to manage both planned and unplanned outages
and to take advantage
of the flexibility, efficient use of resources, and cost savings
that cloud computing offers.
The IBM enhanced stretched cluster design offers significant
functions for maintaining
business continuity in a VMware environment. You can dynamically
move applications across
data centers without interruption to those applications.
The live application mobility across data centers relies on these
products and technologies:
IBM System Storage® SAN Volume Controller enhanced
stretched cluster solution
VMware Metro vMotion for live migration of virtual
machines
A Layer 2 IP Network and storage networking infrastructure for
high-performance traffic
management
Data center interconnection
