Managing clusters and peers
Clustering supports the use of
Presence
.
All peers in the cluster must have identical SIP domain,
Presence Server and Presence User Agent (PUA) configuration.
If peers in the cluster have the PUA enabled, each peer
publishes information about its own local registrations. This
information is routed to a Presence Server authoritative for the
cluster’s domain.
If peers have the Presence Server enabled, the Presence
database is replicated across all peers in the cluster.
When
viewing presence status
on a peer in a cluster:
•
Publishers
will show all presentities across the cluster for
whom presence information is being published.
•
Presentities
will show any presentity for whom a subscription
request has been received on the local VCS only.
•
Subscribers
will show each endpoint from which a
subscription request has been received on the local VCS only.
Clustering and Presence
Overview
Clustering supports the use of
FindMe
. Each peer has its own
FindMe database containing all user account information for
the cluster. When a user account is created or edited on one
peer, that peer shares the information about the changes to all
other peers in the cluster, which then update their own FindMe
databases accordingly.
There is a limit of 10,000 FindMe user accounts per VCS
cluster. Multiple clusters are required if you have more
than 10,000 users.
Note that the replication of FindMe database information uses
a different mechanism (the
TMS Agent
) to that used to replicate
configuration information. Configuration information must
be changed on the master peer only, but changes to FindMe
information can be made on any peer and will be shared with all
other peers.
If you are part of a large enterprise with, for example, TMS
managing several VCS clusters, the FindMe database may
contain details of users and devices in other VCS clusters.
Different clusters are distinguished by their
Cluster name
(see
below). You cannot modify the details of accounts that are not
managed in your cluster.
Cluster name
You must define a
Cluster name
if you are using FindMe, even if
the VCS is not part of a cluster.
If you change the cluster name after creating your user accounts
you will have to reconfigure those accounts to associate them
with the new cluster name. You can do this by running the
transferfindmeaccounts
script. Instructions for how to do this are
contained in the
FindMe Deployment Guide [29]
.
Alterntively, if you try to edit an account that belongs in a
different cluster the system gives you an option to
Move this
account to local cluster
. Selecting this option updates that
particular account so that it now belongs to your local VCS
cluster and hence lets you edit that account's details.
See
Configuring clusters
for more information on configuring the
cluster name.
Clustering and FindMe
Clustering and TMS
Clusters can be monitored from TANDBERG Management Suite
(TMS). For full information, refer to the TMS documentation.
•
TMS version 12.5 or later is required when setting up a
cluster.
•
When a cluster is up and running, TMS is only mandatory if
you are using FindMe or Device Provisioning, however it is still
recommended.
If you were using TMS to manage a cluster running a version of
the VCS software prior to X5, refer to the
TANDBERG Deployment
Guide - Creating a Cluster of VCS peers [27]
for upgrade
instructions.
In previous VCS releases, replication between peers was
managed by TMS. From VCS version X4 onwards,
replication is managed by the VCSs themselves.
