HighPoint RocketRAID 3522 - Manual (Page 10)

Congratulations
SNMP Trap - The RAID adapter can be configured to report events over the network.
When an event is generated by the RAID Management utility, the SNMP Trap will send
SNMP Trap messages to the Trap Receiver.
Network Features
SNMP Manager - Simple Network Management Protocol. Allows the administrator to
view the current state of the entire RAID system.
NTP - Network time protocol. The RocketRAID 35xx’s firmware automatically synchro-
nizes it’s internal clock to match that of the selected server. If a NTP server is not
specified, the adapter will synchronize itself with the host system’s BIOS clock.
The RocketRAID 35xx offers a selection of network-oriented RAID Management
functions. These features are integrated into the card’s firmware, and can be adminis-
trated using the BIOS and Web-based management utilities.
OCE, ORLM and the RocketRAID 35xx
The RocketRAID 35xx supports both Online Capacity Expansion (OCE), and Online
RAID Level Migration (ORLM). Both features are supported by a single function - an
array can be transformed from one RAID level to another RAID level while simulta-
neously being resized, even under I/O load.
Spare disk
A spare disk is a single disk that can be used to automatically rebuild a redundant array
in case of drive failure. Spare disks may also be members of a RAID array. Any available
space on these disks may be used to rebuild other broken arrays.
Legacy disk
Disks attached to the RocketRAID 35xx that contain valid partition tables will be identi-
fied as legacy disks. A legacy disk attached to the RocketRAID 35xx can be accessed by
the operating system, but cannot be used to create RAID arrays. A legacy disk must be
initialized before assigning it to an array.
