APPENDIX F
Configuring Stretched Cluster and
Tiebreaker
This chapter provides an overview that describes stretched cluster basics, provides
prerequisites needed to install and use a stretched cluster, describes how to
configure a stretched clusterstretched cluster, and provides procedures for
installing, configuring, and managing tiebreaker for stretched clusters in the
following topics:
•
•
Configuring a Stretched Cluster
•
Installing and Configuring Tiebreaker
Overview: Stretched Clusters
A stretched cluster is a 7700 Flash Storage Platform where each of the 7700 FSP
Controllers is located in a different network location. A stretched cluster provides
synchronous mirroring and storage redundancy. A stretched cluster 7700 FSP
Controller can fail over to the remote site 7700 FSP Controller, which then takes
over responsibility for the storage and workload of the remote site during a failure.
In a stretched cluster configuration, the two 7700 FSP Controllers could be located
on different floors in the same building or in different buildings in the same city. A
stretched cluster provides synchronous mirroring with array-based high availability
that allows application workloads to run at both sites.
If a failure occurs at either site, the 7700 FSP Controller at the surviving site will
take over storage services for the failed 7700 FSP Controller and your applications
and operations will continue running.
Each stretched cluster site will have a 7700 Controller, one or more Fibre Channel
cluster switches, and one or more 7000 Series or 6000 Series storage shelves to
provide primary local storage services. An external server, where the Tiebreaker
utility resides, manages the interpretation of site status and failover between sites.
