NVMe as L2 Cache - What happens in case of failure
Posted: Wed Apr 26, 2017 4:59 pm
Hi!
I see the option to add an NVMe to both nodes of my HA-setup to increase the cache size.
Can you tell me, what happens, if the NVMe fails? Does the target go "offline" on the host, which uses the NVMe, or does only the L2-cache get deactivated?
The NVMe seems to be a single-point-of-failure, as it is not really redundant.
Thank you for your help
