Local Disk Configuration Policy
Thispolicy configures any optional SAS local drives that have been installed on a server through the onboard
RAIDcontroller of the localdrive. This policy enables you to seta localdisk mode for allservers that are
associatedwith a serviceprofile that includesthe local diskconfiguration policy.
Thelocal disk modesinclude the following:
•NoLocal Storage—For a diskless server or a SAN only configuration. If you select this option, you
cannotassociate any service profile which uses this policy with a server that has a local disk.
•RAID0 Striped—Data is striped across all disks in the array, providing fast throughput. There is no
dataredundancy, and all data is lost if any disk fails.
•RAID1 Mirrored—Data is written to two disks, providing complete data redundancy if one disk fails.
Themaximum array size is equal to the available space on the smaller of the two drives.
•AnyConfiguration—For a server configuration that carries forward the local disk configuration without
anychanges.
•NoRAID—For a server configuration that removes the RAID and leaves the disk MBR and payload
unaltered.
•RAID5 StripedParity—Data is striped across all disks in the array. Part of the capacity of each disk
storesparity information that can be used to reconstruct data if a disk fails. RAID 5 provides good data
throughputfor applicationswith high readrequest rates.
•RAID6 Striped Dual Parity—Data is striped across all disks in the array and two parity disks are used
toprovide protection against the failure of up to two physical disks. In each row of data blocks, two sets
ofparity dataare stored.
•RAID10Mirrored and Striped— RAID 10 uses mirrored pairs of disks to provide complete data
redundancyand high throughputrates.
Youmust include this policy in a service profile, and that service profile must be associated with a server for
thepolicy to takeeffect.
Management Firmware Package
Thispolicy enables you to specify a set of firmware versions that make up the management firmware package
(alsoknown as a management firmware pack). The management firmware package includes the Cisco Integrated
ManagementController (CIMC) on the server. You do not need to use this package if you upgrade the CIMC
directly.
Thefirmware package is pushed to allservers associated with service profiles that include this policy. This
policyensures that the CIMC firmware is identical on all servers associated with service profiles which use
thesame policy. Therefore, if you move the service profile from one server to another, the firmware versions
aremaintained.
Youmust include this policy in a service profile, and that service profile must be associated with a server for
itto takeeffect.
Thispolicy is not dependent upon any other policies. However, you must ensure that the appropriate firmware
hasbeen downloaded to thefabric interconnect.
