The second feature I like a lot is the performance improvement. Performance improvements and better performance predictability are always welcome. More predictable application performance is achieved in vSAN 6.7 U3 by destaging data from the write buffer to the capacity tier. This makes vSAN more efficient and consistent with increased throughput for sequential writes. The increased consistency in destaging operations results in a smaller deviation between high and low latency. This increased throughput also reduces the amount of time necessary for resyncs from repairs and rebuild tasks. The destaging improvement is depicted in the figure below.
However, there are other operations and availability improvements in 6.7 U3. Let's highlight the vSAN 6.7 U3 improvements one by one as published in Release Notes.
