How does Heartbeat Compare to MSCS?

Currently using MSCS to help maintain availability of VC services. It's by no means a perfect solution. Wondering if Heartbeat would be an improvement.

Curious about everyone's (or anyones) experiences of using Heartbeat instead. What does it do better/worse/same? What do you like? What do you hate? What failure scenarios are you protecting against?

Thanks!

(context: we've got ~180 hosts and 2300 VMs across 2 VC instances ... current still VI 3.5, going vSphere in the next 3-5 months)

Geekinabox, the generic frustrations around MSCS apply to vCenter server, although it has been supported for a while now it has proven to be problematic, although this can also depend on your level of experience with MSCS. I have spoken to many large customers that have been down the MSCS route and the biggest issues for most was actually unexpected failovers and support, MSCS is a third party vendor and the customer can find themselves stuck in the middle in regards to obtaining support during a time of need. vCenter wasn't designed to be cluster aware but has been proven to work in certain configurations.

vCS Heartbeat address this by providing a fully VMware supported product that not only provides redundancy but also resillience. The architecture is a active/passive model to provide a target for automatically failover or to switch too manually and can be deployed in a LAN or a WAN. On top of this, vCS Heartbeat is monitoring services, changes to the configuration, plugins installed, and a set of rules to make sure vCenter is functioning (ie vpxd connections, database connectivity etc) and can take corrective action where necessary. It is also fully customizeable for protecting additonally installed products like SRM or VIEW that maybe running on the same server. No additional product licensing is required for the passive server with vCS Heartbeat.

Hope that helps
