2. In the Configure Virtual Disk Parameters section, you can set the following virtual disk parameters:
Table 9. Configure virtual disk parameters
Virtual disk parameters Description
Virtual Disk Name Allows you to enter the name for the virtual disk
NOTE: Allowed characters are A-Z, a-z, 0-9, underscore (_), and hyphen (-) only.
Virtual Disk Size Displays the maximum capacity available for the virtual disk
Virtual Disk Size Unit Displays the virtual disk storage space in megabytes, gigabytes, and terabyte.
Strip Element Size Allows you to select the strip element size The disk striping involves partitioning each
physical disk storage space in stripes of the following sizes: 64 KB, 128 KB, 256 KB, 512
KB, and 1 MB. By default, the strip element size is set to 256 KB.
Read Policy Displays the controller read policy You can set the read policy to:
● No read ahead—specifies that the controller does not use read ahead for the current
virtual disk.
● Read ahead—specifies that the controller uses read ahead for the current virtual disk.
Read ahead capability allows the controller to read sequentially ahead of requested
data and store the additional data in the cache memory, anticipating that the data is
required soon.
By default, the read cache policy is set to read ahead.
Write Policy Displays the controller write cache policy You can set the write policy to:
● Write through—the controller sends a data transfer completion signal to the host
when the disk subsystem has received all the data in a transaction.
● Write back—the controller sends a data transfer completion signal to the host when
the controller cache has received all the data in a transaction.
By default, the write policy is set to Write Back.
Disk Cache Allows you to set the disk cache policy to default, enable, or disable. By default, the disk
cache is set to default.
Default Initialization Displays the virtual disk initialization options. You can set the default initialization to:
● No — The virtual disk is not initialized.
● Fast — The first 8 MB of the virtual disk is initialized.
● Full — The entire virtual disk is initialized.
For more information, see Virtual disk initialization. By default, the default initialization is
set to No.
Create profile based virtual disk
Steps
1. Enter the Dell PERC 11 Configuration Utility. See Navigate to Dell PERC 11 configuration utility.
2. Click Main Menu > Configuration Management > Creating Profile Based Virtual Disk.
The following list of RAID modes are displayed:
● Generic RAID 0
● Generic RAID 1
● Generic RAID 5
● Generic RAID 6
● File Server
● Web/Generic Server
● Database
3. Based on the RAID mode selected, one or more the physical disk selection criteria is displayed.
4. From the Physical Disk Selection Criteria drop-down box, select a criterion based your requirement.
The Profile Parameters of the selected option is displayed.
5. Click Create Virtual Disk.
