Before attending Momentum – this year, I knew very little about how VMware fits in with Documentum architecture. In the past, I have used VM images to set up different configurations for sales demos – this use case is very rudimentary compared to the powerful features that are now available with latest version of VMware.
Here are some of the new features:
- VMotion – live real-time migration of VM images from one server to another
- Dynamic Resource Scheduling – dynamically balancing of resources across resource pool
- HA Enhancement Support
How does VMware fit in the Documentum world?
- Create developer image that can be cloned to be used by all developers – great time saver for WDK developers
“Golden” Test Environment
- Pass development image easily to test environment
- Consolidate and reset test bed rapidly
- Save multiple versions of test images to be reloaded at any point
- Keep development/test image available during product upgrade cycle – this would have be very helpful during 525 to 53 upgrade that I was part of last year
- Clone production data into UAT environment easily
- Real-time scaling
– can scale horizontally – add more content servers to host more users if necessary
– can scale vertically – add CTS/DTS on a server that is not highly utilized
- Test patches on multiple configurations
- Rollback previous image – helpful if you need to rollback the upgrade of Content Server/docbase
All of this may seem intuitive, but official support of virtualization for Documentum products is new. Documentum has always been architected to be scalable – you just needed to buy more servers and licenses. Now, we can do this without adding servers to our data centers, which the infrastructure folks must love hearing this.
