Controller Functions and Features
Key Features
The key features of the DAC960PG include:
• Configuration on Disk (COD)
• Add Capacity
• RAID/SCSI Disk Array Management
• Automatic RAID Functions
• Automatic On-board SCSI Termination
• Enhanced System Performance
• Increased System Availability
• Multiple Operating System Support
Configuration On Disk
Disks and controllers will automatically reconfigure if the system is powered
off and any of the following changes are made, and the system is
subsequently restarted. Operator intervention is not needed, unless a major
change such as RAID level, stripe size, or array size is made.
Any combination of the following changes can be performed.
1. Drives in an array can be removed and reinstalled in any order (target
IDs can be switched within an array).
2. The drives’ SCSI channel assignments can be changed.
3. A DAC960PG controller can be exchanged with another DAC960
controller as long as both controllers have 4.x or higher firmware.
Add Capacity
Add Capacity allows the user to add one or more drives to an existing array
to expand the capacity of the array. This will not increase the size of a
logical drive, but will create additional space in which to add a new logical
drive. The user is not required to take the array off-line or reformat the array.
Performing a backup as a normal operation is always recommended prior to
adding capacity.
