when I deleting snapshots in vcenter I noticed dip in the cache hit rate. why is that?
Nimble SSD is used for "hot active reads". I am assuming that your snapshots are older and all the data is not accessed all the time. So when we go to remove the VMware snapshots that data is being remove from data not on SSD. It will not affect your performance it just make the numbers look less because the data you are removing is old data and you are not using that data anyways so no effect.
Thank you for your question. It has been forwarded to the appropriate team, and we are researching it.
