• Cache Mode
The RAID storage supports “Write Through” and “Write Back”
cache.
• Volume Write Protection
When "Volume Write Protection" is enabled on the "Modify
Volume Set", host commands fail if they are issued to a volume
in that RAID controller and attempt to modify a volume's data
or attributes. Volume Write Protection is used primarily for
customer-initiated disaster recovery testing.
• Full Volume Encryption
ARC-8050T3U have featured with controller based hardware
encryption function. Controller based hardware encryption de-
scribes the encryption of data occurring at the disk array con-
troller before being sent to the disk drives. Since RAID control-
ler is a natural central point of all data therefore encryption at
this level is inherent and also reduces deployment complexity.
ARC-8050T3U RAID controller has dedicated electronic circuitry
for the cryptographic engine embedded in the ROC and operat-
ing at full channel speeds. The hardware encryption does not
impact the performance of ARC-8050T3U RAID controller and
can implement on any kinds of HDD that is transparent to the
user, the OS, and applications.
Encrypting your volume can give your data an extra layer of
protection be yond setting up a controller password. Encryption
will conceal your volume’s data and make accessing the files
almost im possible for anyone who does not know your encryp-
tion key. Data saved in the volume will be hidden by Algorithm
developed by Areca Technology. With this scramble process, no
one can see and access into the hidden volume data without
access key. ARC-8050T3U support 128- and 256-bit encryp -
tion keys using AES(a key size of 128, or 256 bits), or pass -
word (a variable key size). Each encryption key size causes
Note:
• RAID level 3 can’t modify the cache stripe size.
• Roaming the stripe size 256K/512K/1M Raid Set to firmware
version older than 1.52 will cause data corruption.
