Select RAID 60 to implement striping across more than one RAID 6 span. RAID 60 Groups
n*s
disks as one
large virtual disk with a capacity of
s*(n-2)
disks, where
s
is the number of spans and
n
is the number of
disks within each span. RAID 60 provides increased data protection and better read performance, but
slower write performance.

Create Virtual Disk Express Wizard (Step 2)
The Create Virtual Disk Express Wizard - <Controller Name> page displays the summary of attributes of the selected
RAID level. The attributes include Bus Protocol, Stripe Element Size, Read Policy, and the selected physical disk. The
default values of the virtual disk attributes excluding the RAID level are recommended for the selected RAID level.
1. In the Name field, type a name for the virtual disk.
The virtual disk name can contain only alphanumeric characters, spaces, dashes, and underscores. The maximum
length depends on the controller. In most cases, the maximum length is 15 characters. The name cannot start with
a space or end with a space.
NOTE: It is recommended that you specify a unique name for each virtual disk. If you have virtual disks with
the same name, it is hard to differentiate the generated alerts.
NOTE: If a physical disk is receiving a SMART alert, it cannot be used in a virtual disk. For more information on
SMART alerts, see Monitoring Disk Reliability On RAID Controllers.
2. In the Size field, type the size of the virtual disk.
The virtual disk size must be within the minimum and maximum values displayed near the Size field. For information
on how the maximum virtual disk size is calculated, see Calculation For Maximum Virtual Disk Size.
In some cases, the virtual disk is slightly larger than the size you specify. The Create Virtual Disk Wizard adjusts the
size of the virtual disk to avoid rendering a portion of the physical disk space unusable.
3. Click Finish to complete the virtual disk creation.
For PERC H700 and PERC H800 controllers, if any of the drives you selected is in the spun down state, the following
message is displayed:
The below listed physical drive(s) are in the Spun Down state. Executing this
task on these drive(s) takes additional time, because the drive(s) need to
spun up.
The message displays the ID(s) of the spun down drive(s).
Click Go Back To Previous Page to return to Create Virtual Disk Express Wizard page, if you want to change your
selections.
Click Exit Wizard to cancel the virtual disk creation.
The virtual disk is displayed in the Virtual Disk(s) on Controller <Controller Name> page.

Does my controller support this feature? See Supported Features.
The Create Virtual Disk Advanced Wizard allows you to specify the read, write, and cache policy, and parameters such
as RAID level, bus protocol, media type, and encrypted disk for the virtual disk. You can also select the physical disks
and the controller connector. You must have a good knowledge of RAID levels and hardware, to use the Advanced
