DescriptionName
This can be one of the following local disk policy modes:
• No Local Storage—For a diskless server or a SAN only
configuration. If you select this option, you cannot associate any
service profile which uses this policy with a server that has a local
disk.
• RAID 0 Striped—Data is striped across all disks in the array,
providing fast throughput. There is no data redundancy, and all
data is lost if any disk fails.
• RAID 1 Mirrored—Data is written to two disks, providing
complete data redundancy if one disk fails. The maximum array
size is equal to the available space on the smaller of the two drives.
• Any Configuration—For a server configuration that carries
forward the local disk configuration without any changes.
• No RAID—For a server configuration that removes the RAID
and leaves the disk MBR and payload unaltered.
• RAID 5 Striped Parity—Data is striped across all disks in the
array. Part of the capacity of each disk stores parity information
that can be used to reconstruct data if a disk fails. RAID 5 provides
good data throughput for applications with high read request rates.
• RAID 6 Striped Dual Parity—Data is striped across all disks in
the array and two parity disks are used to provide protection against
the failure of up to two physical disks. In each row of data blocks,
two sets of parity data are stored.
• RAID10 Mirrored and Striped— RAID 10 uses mirrored pairs
of disks to provide complete data redundancy and high throughput
rates.
If you choose No RAID and you apply this policy to a server
that already has an operating system with RAID storage
configured, the system does not remove the disk contents.
Therefore, there may be no visible differences on the server
after you apply the No RAID mode. This can lead to a
mismatch between the RAID configuration in the policy and
the actual disk configuration shown in the Inventory > Storage
tab for the server.
To make sure that any previous RAID configuration
information is removed from a disk, apply a scrub policy that
removes all disk information after you apply the No RAID
configuration mode.
