DIMM. DIMMs that are likely to receive a fatal/uncorrectable memory error are removed from
operation automatically, resulting in less system downtime.
See the server-specific user guide for DIMM population requirements.
•
Mirrored Memory Mode—Provides protection against uncorrectable memory errors that would
otherwise result in system failure. In this mode, the system maintains two copies of all data. If an
uncorrectable memory error occurs, the system automatically retrieves the good data from the
mirrored copy. The system continues to operate normally without any user intervention. If the system
supports hot-plug memory, the failed memory can be replaced while the system continues to operate.
•
RAID Memory Mode—Provides protection levels similar to Mirrored Memory Mode, and it requires
less memory allocation than full redundancy.
Embedded SATA RAID
HP provides the SATA RAID feature through use of the HP Storage Manager. This feature enables RAID
functionality (RAID 0, RAID 1, or RAID 10) for the embedded SATA controller in the system.
Required hardware
Installing the SATA RAID driver may require a diskette drive and CD-ROM drive. Some server blades do
not ship with these drives as standard hardware.
NOTE: Systems with Microsoft® Windows Server™ 2003 and HP embedded drivers do not
require additional hardware.
Diskette and CD-ROM drive options
To acquire a diskette drive option or CD-ROM drive option for a server blade, contact an HP authorized
reseller.
