 Ceph iSCSI Gateway
 ==================
 
-The iSCSI Gateway presents
-a Highly Available (HA) iSCSI target that exports RADOS Block Device (RBD) images
-as SCSI disks. The iSCSI protocol allows clients (initiators) to send SCSI commands
-to storage devices (targets) over a TCP/IP network, enabling clients without
-native Ceph client support to access Ceph block storage.  These include
-Microsoft Windows and even BIOS.
-
-Each iSCSI gateway exploits the Linux IO target kernel subsystem (LIO) to provide
-iSCSI protocol support. LIO utilizes userspace passthrough (TCMU) to interact
-with Ceph's librbd library and expose RBD images to iSCSI clients. With Ceph’s
-iSCSI gateway you can provision a fully integrated block-storage
-infrastructure with all the features and benefits of a conventional Storage Area
-Network (SAN).
