A-10Adaptec RAID Configuration Utility (ARC)Controller Configuration OptionsThe Controller Configuration options are described in the tablebelow.Option DefaultModelsAffected DescriptionDrives WriteCacheDrive'sDefaultAll When Enabled, write cache isenabled, providing maximum driveperformance. When Disabled, nowrite cache is used on the drive. Bydefault, the drive’s setting is used.Caution—When Enabled, there is aslight possibility (less than withcontroller cache) of data loss orcorruption during a power failure.Runtime BIOS Enabled All When Enabled, the controller BIOSallows the controller to act as abootable device. Disabling the BIOSallows another suitable controller toact as the boot device.AutomaticFailoverEnabled All When Enabled, the controllerautomatically rebuilds an arraywhen the failed drive is replaced.When disabled, the array must berebuilt manually.ArrayBackgroundConsistencyCheckDisabled All When Enabled, the controllerconstantly performs a verificationon a redundant array to dataintegrity. In the case of RAID 1 or 10,consistency checks assure that thedata between like blocks match. Inthe case of a RAID 5 or a RAID 0,consistency checks assure that datain the stripe and the calculatedparity for the stripe match.Consistency checking processesreduce performance. For a RAID 5or a RAID 50, the performancereduction is significant.BBS Support Enabled Seenote 1 When Enabled in systems thatsupport BBS, controller is presentedas a bootable device in the hostsystem's BIOS for boot deviceselection.
