1 MB I/O
PERC 10 controllers support a 1 MB I/O feature; if the capacity of I/O frame is greater than 1 MB, the I/O frame is broken into
smaller chunks.
Auto Configure RAID 0
Auto Configure RAID 0 feature creates a single drive RAID 0 on each physical disk that is in the ready state. For more
information, see Auto Configure RAID 0 on page 55.
Disk roaming
Disk roaming is when a physical disk is moved from one cable connection or backplane slot to another on the same controller.
The controller automatically recognizes the relocated physical disks and logically places them in the virtual disks that are part of
the disk group.
CAUTION: It is recommended that you perform disk roaming when the system is turned off.
CAUTION: Do not attempt disk roaming during RAID level migration (RLM) or online capacity expansion (OCE).
This causes loss of the virtual disk.
