lrbd both advantages and iSCSI RADOS block device embracing diversity. In iSCSI target host (referred lrbd using the gateway) lrbd , the need to use any application that may benefit from the chunk store Ceph, without running Ceph client protocols as well. The user may use iSCSI target end or any other protocol to target LIO, which can store conversion-target-initiated RBD all I / O operations.
- ISCSI gateway CEPH single cluster
lrbd inherently high availability, and supports multi-path operations . Thus, the downstream initiator iSCSI host may use a plurality of gateways for high availability and scalability. When the iSCSI configuration comprising a plurality of gateway communication, the initiator iSCSI request can be load balanced among multiple gateways. If a gateway fails (temporarily inaccessible, or because maintenance has been disabled), will continue to transparently handle I / O through another gateway.
