Vizioncore recommends the COS reservation changes to made on the ESX hosts to optimize the regular backup of VMs. These ESX resource reservations are not mandatory and recommended only for operation efficiency.
The ESX host recommendations are based on Vizioncore and customer experience. By increasing the amount of CPU time reserved for the service console and allocating 800MB of RAM, provides greater resource availability for the compression engine as well as ensuring efficient snapshot operation for multiple VMs.
If you are using ESX hosts then please
You will also want to check the configuration of your ESX hosts Service Console for the following resource adjustments.
---- ESX host resource changes ----------------------------------------------------------------
1. Increase CPU Reservation to 1500 can be done on the fly
To increase the CPU reservation that the service console has over CPU 0 in a ESX host, the VI Client is used.
- Select the ESX host in VI Client,
- Select the configuration tab
- Under Software, click "System Resource Allocation"
- Click "Edit" and change the CPU Reservation to 1500 MHz.
2. Increase Memory Reservation to 800 MB (This change requires a RESTART of the ESX host to take effect.)
- Click on the ESX host in the VI Client,
- select the configuration tab,
- Under Hardware, click Memory.
- click "Properties" and modify the default of 272MB to 800MB. (reboot of the ESX server is required)
