Ambedded releases the Ceph Management GUI UVS manager 2.14.17

23 Jun, 2020 Ambedded

Ambedded announces the release of
UVS manager v2.14.17 for
Ceph storage appliance.

We are glad to announce the release of
UVS manager v2.14.17, v2.14.17 is our second release of the year 2020.
UVS manager supports both community version
Ceph on
Mars 400PRO and
SUSE Enterprise Storage version on
Mars 400SES.

The highlight of this release is the implementation of RBD mirroring.
Ceph supports the RBD mirroring since
Ceph Jewel. With RBD Mirroring, users can quickly re-activate the storage service without waiting for the primary site recovers from a disaster.

Users can deploy rbd-mirroring to replicate their RBD images between two
Ceph clusters. However, configuring RBD mirroring and manage mirror peers by commands may be overwhelming to the entry-level users. UVS RBD-mirroring features enable you to deploy the rbd-mirroring quickly, configure peers, view mirror status. It also supports you to promote and demote primary and secondary site during the failover and failback scenarios. You can find how to operate the RBD mirroring by using
UVS manager in the end of this article.


Ceph RBD mirroring is a disaster prevention solution by geo-replication
