System Administrators are always looking for the additional extra performance tuning. The VMware document bellow provides quick and easy tips to streamline your VSphere environment.
During my readings I have found a ERR – The bellow statement is incomplete or misguiding administrators.
The VMware vCenter Management Webservices can use between 128MB and 1.5GB of RAM on the
vCenter server system. In vCenter installations not using linked mode this service is used only for
searches, and thus if search capability is not required the service can safely be turned off to reduce the
vCenter server’s memory usage. Note, however, that vCenter installations using linked mode (that is,
most installations with more than one vCenter server) require this web service.
If VCenter Management Webservices is disabled you will be also tuning VCenter Service Status off. I don’t know about you but for me Service Status is VERY important.
VMware just released a very useful, 54-pages free ebook that collects many the principal guidelines to optimize the performance of the new vSphere: Performance Best Practices for VMware vSphere 4.0.
It includes four chapters:
- Hardware for Use with VMware vSphere
- ESX and Virtual Machines
- Guest Operating Systems
- Virtual Infrastructure Management
If you are planning a migration to the new platform this is a highly recommended reading.
