How cache is affected by other operations in the storage system
Upgrades and changes to other components in your storage infrastructure typically do not have any negative effect on the cached data.
A corrupt SSD or PCIe card could cause the loss of cached data, but typical updates or upgrades to other storage components in the caching system will not cause cached data to be lost. Some common operations are listed below:
Upgrading NetApp storage with a new Data ONTAP release.
The Flash Accel intelligent cache coherency feature will invalidate the outdated cached data when a NetApp SnapRestore operation occurs. All valid cache information is retained, which makes for a much faster rewarming of the cache during a restore operation.
At this time Flash Accel is certified to work only with vSphere 5.0, but future upgrades of VMware software should not affect the cache.
