Smaller block sizes are better for databases, larger block sizes are better for applications with large files.		The '''Block Size''' defaults to 8KB in '''Auto''' mode (as of QuantaStor 5.3) when no SSD log is on the pool and 8KB when SSD write log is present for the underlying storage pool. Smaller block sizes are better for databases, larger block sizes are better for applications with large files.

	These three separate CHAP user/passwords (user, cloud, volume) policy settings can all be applied to a volume at the same time. If the ''user'' account has no CHAP password on it then user CHAP settings are not applied to the volume, and similarly, if you add the volume to a ''storage cloud'' it will only apply its CHAP settings to the volume if they're present in the ''storage cloud'' configuration.
