VMware View VDI Flash Calculator v2.7 Released
I have just uploaded a new release of the online VMware View VDI Flash Calculator.
This new release is add some key storage capabilities. The VDI calculator can be found at http://myvirtualcloud.net/?page_id=1076. Alternatively, go to my blog homepage and select VDI Calculator on the top bar.
- Added support for storage array caching calculation capabilities
- Added support for storage block de-duplication
- Added configuration validations based on storage protocol (Block and File)
- Added support for VAAI (vStorage API for Array Integration) validations
- Added higher degree of control over refresh cycle for floating pools
- Small UI changes
Caching – Intelligent arrays make use of DRAM and/or SSD memory to store most accessed blocks in memory. Memory stored in memory do not require backend spindle access, therefore reducing the total requirements on the backend. This is a powerfull option but should be used with caution. Normally is not possible to know the caching ratio until a project pilot is done.
Block De-duplication – Some arrays have either in-line block de-duplication or offline block de-duplication that helps to reduce the total capacity requirement. The de-duplication ratio for VDI deployments is normally high due to the block communality across multiple Windows desktop VMs. This is a powerful option but should be used with caution. Normally is not possible to know the caching ratio until a project pilot is done.
Check out the VDI calculator training video. You can find the video at http://myvirtualcloud.net/?p=2551 (not updated for release 2.7)
I have also updated the manual to help you to better use the VDI Flash Calculator. The manual can be found at http://myvirtualcloud.net/?p=1927.
