HA arquitecture

[cavagnaro]

Hi guys,
Our presales has sold an HA solution of this however architecture is not very clear.
For me the DB and File storage should be external, on a 3rd server. So if Recorder A or B goes down all keeps working.
Now, this means three servers as minimum.

However ALU slides (I don't trust commercial material) show only 2 servers. I see a SQL Replication process with this description:

Replication process copies a call record along with the physical call file from primary to secondary or vice versa. This process flags the call record in the database when it is synced. This flag can be reset with the help of a SQL script and the replication service will replicate all the records again on secondary but the most important thing is the size of the data to replicate. If the size of the data to be replicated is huge, the number of records needs to be configured in replication service configuration file. Please contact, AlcatelLucent technical support team, to handle SQL scripting and replication service file changes.

Is all I can find on documentations about this.

This would mean to have 2 SQL servers, right? and like a process doing the copy/paste of the recordings

Has anybody installed and configured this way? Any ideas?

Thanks

Hi,

Actually this means you need 2 SQL servers, but, AFAIK, since 2012 any SQL license permits you to have a second instance for replication purposes.

Cav, two things to check: SQL for CDR data and recordings storage.
For SQL depends, do you have already an SQL infrastructure, maybe you can use that one and maybe it is already redundant (e.g. HA or Always On)

I am not familiar with OmniPCXRecord.

Yeah,
As per Joao comment, that works only when SQL server is licenses by Core. So customer will have to provide a way.
So can be 2 servers each with SQL and use the replicatin scripts from ALE. Or. 2 Recording server and 1 external for DB and Recording files
