Frequently Asked Questions
This section lists frequently asked questions and other issues with Promise
Technology’s Software RAID On Mother Board (ROMB) system.
Pre-Installation
What kind of hard drives can I use for a ROMB logical drive?
You can use any Serial ATA (SATA) physical (disk) drives to create logical
drives on the ROMB controller. Use matching drives for multiple-logical
drives to maximize capacity usage as well as performance.
Will ACPI work with physical drives on the ROMB?
ACPI works on Windows but not on Linux.
Drive Issues
Can I add a drive to a ROMB logical drive via hot-swap and dynamically
adjust the logical drive size?
Yes. ROMB supports dynamically adjustable RAID size and RAID level. See
“Migrating a Logical Drive” on page 80.
Do the physical drives on the ROMB have to be the same size?
The physical drives connected to the ROMB controller do not have to be the
same size. If the sizes differ, the ROMB controller will truncate the bigger
drive so the drives match. The resulting difference in drive space is
unusable, so avoid using physical drives of significantly different capacities.
