I moved the most important VMs to a additional SSD Raid5 Array and updated the DSS V6 to "6.0up99.8101.8328 64bit", even with the small update I ended at a old LSI driver version in V6 (2011 or so).
Is it now safe to reenable CacheCade after updating the LSI FW to the most current level?
Btw. if you confirm that the S200 box from xtivate.de is not certified, I will ask the guy why the sold me a S200 and 200.
