Fault Prevention

Keeps data available and server running while a failed drive is being replaced; several fault tolerance configurations are supported including:

• Distributed Data Guarding (RAID 5): This allocates parity data across multiple drives and allows simultaneous write operations. It is recommended for up to 6 hard drives.
• Drive Mirroring (RAID 1, 1+0): This allocates half of the drive array to data and half to mirrored data, providing two copies of every file.
• Drive Migration and Roaming: This feature ensures that the system can identify the data on a drive and insert it appropriately into an array in the event that the drives are inserted incorrectly.

Capacity

Given the internal server storage need for low cost capacity expansion, the 6-port SATA RAID controller offers:

• Six SATA ports supporting up to 6 internal disk drives
• Up to 4.5TB of storage per PCI slot
• Online capacity expansion
• RAID Level Migration to increase the size of an array
• NOTE: Support for a single logical drive is limited to 2TB.
