When using a SAS RAID Ctrl (MegaRAID SAS)
Configure RAID with an internal hard disk unit which is connected to a SAS RAID Ctrl. The array
controller to be employed is "MegaRAID SAS" and available RAID level is "RAID 0 / RAID 1/ RAID
1+0 / RAID 5/ RAID 6". For details, refer to "MegaRAID SAS Users Guide" in Array Controller
Document & Tool CD.
When using an onboard software RAID (SATA model only)
Configure RAID with an internal hard disk unit which is connected to an internal hard disk connector on
the baseboard. The array controller to be employed is "Embedded MegaRAID SATA" and available
RAID level is "RAID 0" or "RAID 1". For details, refer to "Embedded MegaRAID SATA Users Guide"
in Array Controller Document & Tool CD.
Only one array controller is available with connecting to the internal hard disk. Multiple array
controllers can not be used.
When RAID-configured hard disk unit is used
Hard disk units that have been used before may have unwanted partition information or array
configuration information, which may cause unexpected problems. If you connect any hard disk units
with usage history to this server, format them at low level on another system before connecting them
to the server. For information on how to format the hard disk, refer to the manual supplied with the
system to be used.
Number of hard disk units
If the number of actually installed units is less than that the setting for the number of units (plus one,
when hot spare is specified), installation using ServerStart is aborted because of an error.
When the number of actually installed hard disk units is larger than configured, the disk units are set
up according to the setting. Extra units will be configured as standby disk units.
