4.4.2 Rebuilding Priority Setting

When the unit is building or rebuilding a RAID set, the RAIDBank5 processor will be shared between the building task and host I/O. This option specifies the relative priority of data I/O and background rebuilding task of RAIDBank5 RAID subsystem. This value has no effect under normal operation but will dictate the length of RAID creation or rebuilding process and the available processor time to service host I/O. The lower the rebuild priority, the longer the rebuild process will take but the impact on host will be lessened. Conversely, the higher the rebuild priority the quicker the rebuild process will take but the impact on host I/O performance will be greater.

4.5Encryption Management The RAIDBank5 RAID subsystem

integrates real-time data encryption/decryption function. The encryption algorithm implemented by the RAIDBank5 is based on AES (Advanced Encryption Standard) with a key length of 256-bit. The encryption key saved in AES USB key fob can be copied to another AES USB key fob or saved as a file for backup. Your RAIDBank5 comes with a blank AES USB key fob for this purpose. Before creating AES- RAID volumes, The AES USB Key fob will need to be initialized.

4.5.1 New Key Generation

The included non-encrypted AES USB key fob will need to be initialized before first time use. To initialize a AES USB key fob, insert the key into the RAIDBank5, select the radio button labelled

“Random Generation” and click the corresponding . A series of dialog boxes will confirm that the key generation was successful and prompt you to reboot the RAIDBank5 to activate. If

the AES USB key fob is encrypted already, a warning message would pop up. Click to

overwrite the original AES key or click to abort.

!WARNING! Initializing a AES USB key will erase any previous key definition. Any prior encrypted RAID sets will no longer be able to use the AES USB key for decryption!

Once key generation is complete, the RAIDBank5 Manager will prompt you to save a local backup of the key to a file. Micronet advises customers to keep a backup file at all times.

!IMPORTANT! Encrypted AES-RAID volumes are inaccessible without the AES USB Key. Micronet recommends keeping a backup AES key at all times to allow recovery in case of a lost or overwritten AES USB key.
