Will a failover event on DSS V6 cause data loss when using SSD drives for data caching?

When using read-cache, there is no problem here, nothing is lost.
Only in case of write-cache there is danger of data loss once the SSD fails.
Open-E DSS V6 Failover FIXES THIS PROBLEM !
Thanks to IO-error management, DSS will failover properly in case of primary array corruption.

The way replication is managed, local write operations on the primary node are considered completed only after both the local and the remote disk write have been confirmed. As a result, loss of a single node will not lead to any data loss.
