Yes, much to my surprise today SRM 4 is now available from the VMware download site.



I was at a customers site this morning when an email from VMware come through on my BlackBerry announcing SRM 4 had been released, After racing home at the end of the day I logged in and started to download the new SRM 4 package and Celerra Storage Replication Adapter. Look at that pitiful download speed, it was like watching paint dry.

I havent had a chance to read over the release notes properly yet, but here’s whats new.  Keep posted as ill be posting more about SRM 4 over the next few days.

Also if your interested in the documentation, here are the links to the Admin Guide and Compatibility Guide

    Enables many-to-one pairings of protected sites with a recovery site. For more information, see the technical note Installing, Configuring, and Using Shared Recovery Site Support, which is available at
  • Resilience in the face of vCenter unavailability during a test recovery.
    Placeholder virtual machines can be quickly repaired after the protected site vCenter becomes available again.
  • New repair-mode installation features.
    You can run the SRM installer in repair mode if you need to change configuration parameters such as vCenter credentials, database connection information or credentials, and certificate details.

    SRM recovery plans can now power-on or power-off a host that is in standby mode.
  • New Option to dr-ip-customizer Utility
    The dr-ip-customizer utility now logs less verbose diagnostic output by default. To force dr-ip-customizer to log the same level of diagnostic output that it produced in earlier releases, use the -verbose option.

    When you select certificate authentication, the SRM installation validates the certificate you supply before continuing. Certificates signed with an MD5 key are no longer allowed.
  • Support for Protecting Fault-Tolerant Virtual Machines.
    SRM can now protect virtual machines that have been configured for fault-tolerant operation. When recovered, these virtual machines lose their fault tolerance, and must be manually reconfigured after recovery to restore fault tolerance.
