ServeRAID Controller Information Panel When you select a ServeRAID controller from the Main Tree, the following information appears in the Main Panel on the right: Controller Type shows the type of ServeRAID controller, such as ServeRAID II, ServeRAID-3H, or ServeRAID-3L. BIOS Version shows the level of basic input/output system code currently installed for the ServeRAID controller. Firmware Version shows the level of microcode currently installed for the ServeRAID controller. Physical Slot shows the actual physical slot location for the ServeRAID controller; for example, PCI slot 4. Battery Backup Write Cache provides information about the optional battery-backup cache device. Statements such as Installed, Not Installed, Defective, or Replace Battery might appear for this feature. Read-Ahead Cache Mode shows the current setting, Enabled or Disabled, for the read-ahead cache mode. (See page 89 for more information.) Stripe-Unit Size shows the current setting of 8 KB, 16 KB, 32 KB, or 64 KB for the stripe-unit size. (See "Interleave depth and stripe-unit size" on page 67 and page 90 for more information.) Rebuild Rate shows the current setting (High, Medium, or Low) for the rebuild rate. (See page 89 for more information.) Hot-Swap Rebuild shows the current setting, Enabled or Disabled, for the hot-swap rebuild feature. This feature is set to Enabled when the level of ServeRAID firmware in use supports this feature. Data Scrubbing shows the current setting, Enabled or Disabled, for the data-scrubbing feature. This feature is set to Enabled when the level of ServeRAID firmware in use supports this feature. The data-scrubbing feature continuously reads all sectors of RAID level-1 and RAID level-5 logical drives "in the background" while the system is running. If a defective sector is found, it is automatically repaired. With this feature Enabled, you no longer need to synchronize RAID level-1 and RAID level-5 logical drives on a weekly basis. Auto-Synchronization shows the setting for this feature. The auto-synchronization feature always appears as Enabled when the level of ServeRAID firmware in use supports this feature.
