Smart Components for Online ROM Flash

Online ROM flash technology consists of a combination of components that allow
system administrators to upgrade system or option ROM images across a wide range
of HP servers and server options while the server is running. The ROM upgrades are
performed locally or across a network from a single point of execution and are
flashed individually or grouped together to perform multiple ROM upgrades in a
single step.
HP Smart Components for ROM Flash include installation logic that automatically
checks for hardware, firmware, and operating system dependencies, installing only
the correct ROM upgrades required by each target server.

Advanced Data Guarding

As storage capacities continue to rapidly expand, disk drive fault protection becomes
more important. This fault protection needs to be implemented without doubling the
investment in disk drives or a new storage infrastructure. Currently, RAID 5 is only
recommended for protecting up to 14 disk drives in an array. RAID 1 provides
greater fault protection, but requires every drive to be mirrored, so it is often too
costly to implement on large RAID volumes.
With Advanced Data Guarding (RAID ADG), you can safely and economically
protect a RAID volume of up to 2 TB and a total of 56 disk drives. RAID ADG offers
fault protection greater than RAID 1 or RAID 5 and only consumes the capacity of
one additional disk drive for each distributed parity data drive.
RAID ADG is essentially an extension of RAID 5, which allows for additional fault
tolerance by using a second independent distributed parity scheme. Data is striped
across a set of drives, just as in RAID 5, and a second set of parity is calculated and
written across all the drives. RAID ADG provides for an extremely high data fault
tolerance and can sustain multiple simultaneous drive failures. This solution is very
important for protecting mission-critical data.
Only the Smart Array 5300 Controllers support RAID ADG. The Smart Array
5304/128 is shipped with RAID ADG and is available as an upgrade option for the
