1 SAS Controller PCI-Express
 
Important notes
»For the connection of SAS hard disks, a SAS controller is required.

Please choose a SAS Controller because SAS hard disks can not be connected to a SATA controller.
 
comments
»The Battery Backup Unit (BBU) for ICP Raid Controller can only be used with an ICP Raid Controller.
Per controller one BBU is required.

Advantages of a BBU

In the case of an electrical power outage, data which have not been written on the hard disks will be saved in a buffer.

Due to data protection reasons, you should always use a BBU when the writing cache is activatd.
