the algorithm to behave slightly differently, so the increasing
key sizes not only offer a larger number of bits with which you
can scramble the data, but also increase the complexity of the
cipher algorithm. ARC-1882 adapters provide five new key
options in the Full Volume Encryption:“Disable”, “256Bit key,
Password”, “256Bit key, AES”, “128Bit key, Password”, “128Bit
key, AES”. You can generate the new key by CLI utility or API
code function.
This volume encryption function can only work with ARC-1882
series with any kinds of HDD. You can follow below steps to en-
able the function.
1. Create volume set with “Full Volume Encryption” capability in
the web management.
2. Use CLI “vsf genkey” command or API code to generate key
file.
3. Use “Download Volume Key File” in the web management or
use CLI “vsf dlkey” command to download volume key file
into firmware and unlock the volume.
4. Follow step 3. to unlock volume if volume locked.
• Tagged Command Queuing
The “Enabled” option is useful for enhancing overall system
performance under multi-tasking operating systems. The
Command Tag (Drive Channel) function controls the SAS
command tag queuing support for each drive channel. This
function should normally remain “Enabled”. “Disabled” this
function only when using SAS drives that do not support
command tag queuing.
• SCSI Channel/SCSI ID/SCSI Lun
SCSI Channel: The RAID storage function is simulated as an
external SCSI RAID controller. The host bus is represented as a
SCSI channel. Choose the SCSI Channel.
SCSI ID: Each SCSI device attached to the SCSI card, as well
as the card itself, must be assigned a unique SCSI ID number.
A SCSI channel can connect up to 15 devices. The RAID storage
is a large SCSI device. Assign an ID from a list of SCSI IDs.
SCSI LUN: Each SCSI ID can support up to 8 LUNs. Most 6Gb/s
SAS controllers treat each LUN like a SAS disk.
