I know for HDD arrays that having multiple log files from different databases has a performance hit as it changes the IO pattern from sequential to random for the array. So having an array per database for it's logs is a best practice.
Does anyone have any suggestions about running multiple SQL Server databases with the log files for each of those databases existing on one SSD array?
Does anyone have experience with the differences of Hitachi's FMDs vs SSDs for their HUS hardware? I'm concerned with consolidating individual drives down to a few FMDs and not being able to sustain performance between the user databases and tempdb if all I have is disk pool of 4 FMDs for everything.
