When you use the Oracle VM Storage Connect Plug-In for Oracle Flash Storage Systems in the Oracle VM environment, you can create Oracle FS System physical disks using the Oracle VM Manager.
After you add an Oracle FS System, you can create a physical disk. When you create the physical disk, you associate it with an Oracle FS System. The disk automatically has its protocol type enabled based on the storage array type you selected when the Oracle FS System was added and registered with Oracle VM.
You cannot specify a number for a physical disk. When you are presenting (mapping) an Oracle FS System physical disk to an access group, the plug-in automatically assigns the physical disk the next available physical disk number.
You can choose to make a physical disk shareable between virtual machines. When the physical disk is shareable, multiple virtual machines (VMs) can use it as storage. For more information about sharing disks, refer to the Oracle VM documentation on the Oracle Technical Network (http://docs.oracle.com)
Thin provisioning allows an administrator to create a logical volume of any size without committing that capacity at that time. Each application has what appears to be all the storage needed for ongoing operations, but without the physical capacity locked to a particular volume. If you select to thin provision a physical disk, the Oracle FS System plug-in sets the allocated capacity to 0 and sets the addressable capacity to the value you provide. Refer to the Oracle Flash Storage System Administrator’s Guide for more information about thin provisioning.
