PassThru / Bypass Mode
PassThru/Bypass Mode is equivalent to a single-drive JBOD in other
applications. It is not a RAID mode. The PC’s operating system accesses the
drive directly and the drive appears under disk management.
A drive set to PassThru/Bypass Mode does not appear as a logical drive in
SuperBuild or WebPAM PRO.
There are no performance or fault-tolerance features. When a drive fails, all data
on that drive is lost. Any other drives are unaffected.
Figure 4. PassThru/Bypass Mode is a physical drive setting
Note that the SuperTrak TX controller supports up to 32 physical drives
configured for RAID mode. Any additional drives configured for RAID Mode will
become either Stale or Bypass Mode.
PassThru/Bypass Mode is a physical drive setting. See “Configuring Physical
Drives” on page 69 or “Making Physical Drive Settings” on page 118.
