Extensive online configuration options: advanced monitoring and event notification
Management tools provide convenience for configuration of logical volumes plus alerting when errors 
have occurred or are about to occur. 
Patrol Read for media scanning and repairing
Patrol read is a background sentry service designed to proactively discover and correct media defects 
(bad sectors) that arise normally as a disk drive ages. The service issues a series of verify commands 
and if a bad block is discovered, the card's firmware will use RAID algorithms to recreate the missing 
data and remap the sector to a good sector. The task is interruptible based on controller activity and 
host operations. The firmware also provides an interface where the patrol read task can be initiated, 
set up for continuous operation, and terminated from a management application. Patrol read can be 
activated by manual command or automatically. 
Global and dedicated Hot Spare with Revertible Hot Spare support:
A hot spare rebuilds data from all virtual disks within the disk group in which it is configured. 
ServeRAID provides the ability to define a physical disk as a hot spare to replace a failed drive. Hot 
spares may be configured as either global or dedicated. A global hot spare allows any physical drive 
to be designated as a hot spare. A dedicated hot spare will allow the user to assign a hot spare drive 
to a particular array of the same drive type. 
The ServeRAID M1000 Series Advanced Feature Key enables the following features:
RAID levels 5 and 50
LSI SafeStore: support for self-encrypting drive (SED) services
Instant secure erase
Local key management
LSI SafeStore encryption services offer instant secure erase and local key management for SEDs. This 
technology represents a significant step forward in securing data on a disk drive from any unauthorized 
access or modification resulting from theft, loss, or repurposing of drives:
Instant secure erase permanently removes data when repurposing or decommissioning SEDs. 
SafeStore local key management provides the necessary management and protection of SEDs using 
a simple pass phrase, security key identifier, and security key file that can be set and applied to all 
SEDs assigned to a ServeRAID adapter. This removes the complexity of managing each SED’s 
unique encryption key and essentially relieves the administrator from most of the daily tasks of 
securing data.  
Note: To use the SED services of the ServeRAID M1000 Series Advanced Feature Key, you must use 
self-encrypting drives as listed in "Supported disk drives" below.
