Features
The ServeRAID M1015 SAS/SATA Controller has the following features:
Auto-resume on array rebuild or array reconstruction after loss of system power
z
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
z
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
z
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
z
Consistency check for background data integrity
z
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.
