There is no better way to learn the new technology than to see
safely. I have written and seen many blogs / tweets about how great the new memory-tuning feature for XenApp and XenDesktop. I read how this function can reduce IOPS 7 average of 15 IOPS per user Windows 0.1 IOPS. I read how to create this feature functions through a small RAM buffer within each VM. I Tweets show crazy seen IOPS numbers Standard for use of rotating disks.
In fact, I have done some of this analysis and was completely blown away by the results.
But who cares? Who cares if my IOPS be reduced by 99%?
Unfortunately, unless you are responsible for the storage, you probably will not care. But what if this drastic reduction in IOPS had a direct impact on the user experience? And from someone who VDI far used 100% of the time, the user experience is what really what interests me.
seeLet's see what the new RAM cache with a feature disk overflow can do for the user experience ...
What impresses me the most is that the workload did not use a some crazy operation that a typical user would not really. You can easily see the improvement of the user experience with something as simple as browsing a few websites.
And all this is done
Without complex configurations
Without expensive SANs
Without SSDs
Without additional hardware
Without additional licenses
Without a learning curve
update: Only one ESG Released -Report validate the cost savings of RAM cache to disk overflow
