•RAID5 StripedParity—Data is striped across all disks in the array. Part of the capacity of each
diskstores parity information that can be used to reconstruct data if a disk fails. RAID 5 provides
gooddata throughputfor applicationswith high readrequest rates.
•RAID6 StripedDual Parity—Data is striped across all disks in the array and two parity disks are
usedto provide protection against the failure of up to two physical disks. In each row of data blocks,
twosets of paritydata are stored.
•RAID10Mirrored and Striped— RAID 10 uses mirrored pairs of disks to provide complete data
redundancyand high throughputrates.
Ifyou choose No RAID and you apply this policy to a server that already has an operating system
withRAID storage configured, the system does not remove the disk contents. Therefore, there
maybe no visible differences on the server after you apply the No RAID mode. This can lead to
amismatch between the RAID configuration in the policy and the actual disk configuration shown
inthe Inventory >Storage tab for theserver.
Tomake sure that any previous RAID configuration information is removed from a disk, apply
ascrub policythat removes all disk information after you apply the NoRAID configuration
mode.
Note
b) If you want to ensure that the server retains the configuration in the local disk configuration policy even
ifthe server is disassociated from the service profile, check the Protect Configuration check box.
Whena service profile is disassociated from a server and a new service profile associated, the setting for
theProtect Configuration property in the new service profile takes precedence and overwrites the setting
inthe previousservice profile.
Ifyou disassociatethe server from a service profile with this option enabled and then associate
itwith a new service profile that includes a local disk configuration policy with different properties,
theserver returns a configuration mismatch error and the association fails.
Note
c) Continue with Step 4.
Step 3 (Optional) To create a local disk configuration policy that will be available to all service profiles and templates,
dothe following:
a) Click the Create Local Disk Configuration Policy link.
b) In the Create Local Disk Configuration dialog box, complete the fields.
Formore information,see Creating a LocalDisk Configuration Policy, on page 410.
c) Click OK.
d) From the Local Storage drop-down list, choose the policy you created.
