Hi. I'm looking to build a host that will host a few VM's. One of the VM's will be hosting some data bases and I need to ensure good data consistency. I'm planning local storage using a pair of ZFS mirrors (Samsung pm893 ssd's) with a mirror of Slog devices. How should I configure the host to use sync writes and what would be the best disk cache setting for the VM that will be hosting the databases. Thanks in advance for your suggestions.
