Note:
Controller starts to initialize the volume in two conditions
1. Stay in controller bios manager or
2. Boot into OS and the controller driver loaded.
• Stripe Size
This parameter sets the size of the stripe written to each disk
in a RAID 0, 1, 10, 5, 6, 50 or 60 logical drive. You can set the
stripe size to 4 KB, 8 KB, 16 KB, 32 KB, 64 KB, 128 KB,
256KB, 512KB, or 1024KB. A larger stripe size produces bet-
ter read performance, especially if your computer does mostly
sequential reads. However, if you are sure that your computer
does random reads more often, select a smaller stripe size.
Note:
• RAID level 3 can’t modify the cache stripe size.
• Roaming the stripe size 256K/512K/1024K Raid Set to
firmware version older than 1.52 will cause data corrup -
tion.
• Cache Mode
The SAS RAID controller supports “Write Through” and
“Write Back” cache.
• Volume Write Protection
When "Volume Write Protection" is enabled on the "Create
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-1883 RAID adapters have featured with controller based
hardware encryption function. Controller based hardware en-
cryption describes the encryption of data occurring at the disk
array controller before being sent to the disk drives. Since
RAID controller is a natural central point of all data therefore
encryption at this level is inherent and also reduces deploy-
ment complexity. ARC-1883 RAID controller has dedicated
