6.3. iSCSI Backstore
An iSCSI backstore enables support for different methods of storing an exported LUN’s data on the local machine. Creating a storage object defines the resources that the backstore uses.
An administrator can choose any of the following backstore devices that Linux-IO (LIO) supports:
fileiobackstore-
Create a
fileiostorage object if you are using regular files on the local file system as disk images. For creating afileiobackstore, see Creating a fileio storage object. blockbackstore-
Create a
blockstorage object if you are using any local block device and logical device. For creating ablockbackstore, see Creating a block storage object. pscsibackstore-
Create a
pscsistorage object if your storage object supports direct pass-through of SCSI commands. For creating apscsibackstore, see Creating a pscsi storage object. ramdiskbackstore-
Create a
ramdiskstorage object if you want to create a temporary RAM backed device. For creating aramdiskbackstore, see Creating a Memory Copy RAM disk storage object.
