EMC recently released the latest version of SRDF/CE for MSCS. This new release has the following changes:
New Name – The overall product line has been renamed to “Cluster Enabler” and the first product released in this line is SRDF/CE for MSCS. In the near future, MV/CE will be added to this family of products.
Redesigned GUI – SRDF/CE GUI has been completely re-written for this release. The GUI in 3.0 has been simplified and wizards have been streamline, making it easier to configure. The SRDF/CE GUI is more tightly integrated with Cluster Administrator and functions like changing Quorum model in SRDF/CE will also make these changes in MSCS (previous version forced you to manually make this change).
Multiple CE Cluster Management – The CE GUI lets you manage remote clusters and multiple clusters, similar to Cluster Administrator
Windows 2008 support added – Version 3.0 adds support for Windows 2008 clusters.
All quorum models supported
Multiple subnets supported
Windows 2000 support dropped – Good riddance
Support for 5773 code added – Minimum microcode for this release is 5×70.
Support for multiple Symms per cluster – You can now have multiple Symmetrix pairs in a single SRDF/CE cluster. Concurrent SRDF is now tolerated per the product guide.
Site mode changes – The default behavior is now called “Restrict Group Movement” and this is basically a combo of the old “No New Onlines” and “Local Override” settings from previous releases. Basically, groups are allowed to come online where a disk is RW while the RDF link is down, but if the disk is WD, the CE resource will fail to come online. The other option is “Automatic Failover” and this feature is essentially the same as the old “SRDF Override” setting. The “Failstop” option is no longer listed, but it is configurable via CLI. The “Forced Failover” and “Local Override” values have been removed.
Site Mode now set at the GROUP level – Previously, this setting was a cluster wide setting. Now, this value can be adjusted on the individual group level. This gives you greater flexibility on which groups you might consider putting at risk by enabling automatic failover during a site outage.
SRDF/CE resource/registry changes – Most settings for SRDF/CE are no longer stored in the SRDF/CE\Config hive in the registry. Instead, these settings are now stored as private properties of the SRDF/CE resources in the cluster.
Installation changes – CE installation now requires that MSCS be installed first before attempting to configure the cluster for CE…this is similar to the old “Convert MSCS to SRDF/CE” wizard. MSCS must be installed on at least one of the cluster nodes prior to configuring CE.
