We're owning an esxi 6.7 on a small ProLiant DL360 Gen9 with an internal Storage and SSD Cache.
I checked the esxi perfomance tabs and noticed that there is a huge latency spike every minute (light blue graph).
What could cause this spikes? Is this the moment were the SSD Cache empty itself to the HDD Raid?
Because it seems like it is not related to any vm activity?
