What’s In this Version
Chapter 1 7
Support for Asynchronous Mode using EMC/SRDF
The Continentalclusters environment supports configuration with EMC
SRDF/Asynchronous mode for data replication. SRDF/Asynchronous
provides a long-distance replication solutions with minimal impact on
performance. This protection level is intended for customers requiring
minimal host application impact, but need to maintain a restartable copy
of data at target (R2) site. In an environment using SRDF for data
replication, when a disaster occurs at the source (R1) site, a consistent
point-in-time copy of data is retained on the target side.
Metrocluster SRDF version A.05.00 is required. Refer to the Metrocluster
with EMC SRDF Version A.05.00 Release Notes for configuration and
support detail.
Support for HP StorageWorks XP12000 CA Journal 1:1
Data Replication
Continentalclusters supports the environment configured with HP
StorageWorks XP12000 CA Journal 1:1 data replication. Continuous
Access XP Journal is an asynchronous data replication between two HP
XP12000 storage disk arrays. CA Journal uses two main features;
“disk-based journaling” and “pull-style replication”. These two features
reduce XP12000 internal cache memory consumption, while maintaining
performance and operational resilience.
Metrocluster CA XP version A.05.00 is required. Refer to the
Metrocluster with Continuous Access XP Version A.05.00 Release Notes
for configuration and support detail.
