Mapped LUNs appear nested under their target. Go to Storage & Snapshots > iSCSI Storage > iSCSI Target List to view and modify iSCSI targets, iSCSI LUNs, and their mappings. You can view it at Storage & Snapshots > iSCSI Storage > iSCSI Target List. Review the summary, and then click Finish.Mapping an iSCSI LUN to a target allows iSCSI initiators to connect to it. However, QTS cannot save data to the LUN if the storage pool runs out of space.įor more information on a setting, click its tip. This offers greater flexibility as empty space is not wasted. QTS allocates storage pool space to a LUN only when it is needed. This guarantees that the space will be available for connected iSCSI initiators. QES allocates pool space when creating the LUN. Select the allocation type, and then click Next.In this tutorial we will create a block-based LUN. Select Create > New File-Based iSCSI LUN.Select Create > New Block-Based iSCSI LUN.Create a LUN by performing one of the following methods.Go to Storage & Snapshots > Storage/Snapshots.For more a more detailed comparison, see the table at the end of this tutorial. Generally block-based LUNs should be instead of file-based LUNs, as they support more snapshot and virtualization features. There are two types of LUNs available in QTS.īlock-based LUNs use space from a storage pool. You can view it at Storage & Snapshots > iSCSI Storage > iSCSI Target List.Īn iSCSI LUN is a portion of storage space that can be utilized by initiators by connecting it to a target. Follow this wizard to create a block-based LUN. Optional: Select Create an iSCSI LUN and map it to this target.Īfter you have finished creating the target, QTS opens the Block-Based iSCSI.Initiators must authenticate with the specified username and password when Optional: Configure CHAP authentication, and then click Next.Specify a name and alias, and then click Next.If this is the first time you have used iSCSI then QTS will prompt you to enable Go to Storage & Snapshot > iSCSI Storage.Warning: Connecting more than one initiator to the same target might result in data loss or damage to the NAS disks. Initiators connect to targets and use their storage. Clients can partition, format, and use virtual disks exactly like local disks, and then use them for storage expansion or as backup destinations. ISCSI enables clients such as computers, servers, and virtual machines to use storage from your QNAP NAS as virtual disks. By carrying SCSI commands over IP networks, iSCSI is used to facilitate location-independent data storage and retrieval over LANs (Local Area Networks) and WANs (Wide Area Networks). ISCSI (Internet Small Computer System Interface) is an IP-based (Internet Protocol) storage networking standard for linking data storage facilities.
