Disk Management
Improving the fault-tolerance of the hard disk drive can directly result in improving the reliability of the whole
system.
Data loss can be prevented and the utilization of hard disk drive can be improved by setting redundancy of
hard disk drive by grouping with use of optional RAID controller (disk array controller).
Important
The RAID system management utility can monitor RAID system status totally to cope with the failure of the
hard disk drive in a short period of time with the linkage of NEC ESMPRO Manager and NEC ESMPRO Agent.

Universal RAID Utility, NEC ESMPRO Manager and NEC ESMPRO Agent are provided
with the server as standard. Refer to descriptions of each software for the installation
procedure or usage.

6Gbps SAS HW RAID 0/1/5/6/10/50/60
6Gbps SAS SW RAID 0/1/10
Hard disk drive can be replaced while the system is operating.
After replacing the failed hard disk drive with the new one, this feature
restores the data automatically which the failed hard disk saved by
acquiring data from other hard disk drives.
This is a feature to prepare an extra hard disk drive preliminary to replace
a failed hard disk drive. By preparing the hot spare, the rebuilding feature
is activated automatically when a failure occurs and RAID system is
recovered.
