Features
The ServeRAID M1015 SAS/SATA Controller has the following features:
Auto-resume on array rebuild or array reconstruction after loss of system power
Auto-resume uses non-volatile NVRAM to save rebuild progress during a host reboot or power failure
to automatically resume from the last checkpoint. Auto-resume will ensure data integrity is maintained
through the process. The card supports a number of features that are able to be implemented without
rebooting the server. Applications such as email and web server benefit from avoiding downtime
during transition.
Online Capacity Expansion
Online Capacity Expansion (OCE) allows the capacity of a virtual disk to be expanded by adding new
physical disks or making use of unused space on existing disks, without requiring a reboot.
Online RAID Level Migration
Online RAID Level Migration (also known as logical drive migration) provides the ability to migrate a
virtual disk from any RAID level to any other RAID level without requiring a reboot. System availability
and application functionality remain unaffected.
Fast initialization for quick array setup
Consistency check for background data integrity
Consistency Check verifies that all stripes in a virtual disk with a redundant RAID level are consistent.
The consistency check will mirror data when an inconsistent stripe is detected for a RAID 1 and
recreating the parity from the peer disks when in the case of a RAID 5. Consistency checks can be
scheduled to take place periodically.
