Failover and load ballancing over 2 sites?

Created: 15 Feb 2013 | 7 comments

Hello,

I have to give a resillient solution design for a new SEP infrastructure and I am a little unsure of the supported methods of a SEPM configuration where failover and/or clustering is used between 2 geographically dispersed sites. The 2 datacentres will be directly linked by a 100mb connection and each datacentre also has a link into the corporate MPLS cloud. All sites are connected to the datacentres through the MPLS cloud.

What I'd ideally like is to have one SEPM in datacentre 1 and another SEPM in datacentre 2, both with the same priority so that the 5000 clients we have will split between the 2. If one of these goes down then the other SEPM will pick up the load until the other comes back online.

From what I have read, I don't beleive a load ballanced scenario across sites is supported. Can anyone confirm that I have understood that correctly?

If so, what would be my best supported solution?

Many thanks.

Yes I did however it doesnt answer anything about load ballancing across sites. that scenario would obviously be good for failover however we'd ideally like to load ballance clients over the 2 sites. Is this a supported model?

You would need to either decide between failover/load balancing or replication. It has to be one or the other, not both.

You could set it up for failover and than edit the management server list to point clients to the correct SEPMs. For their secondary SEPM, you would set it to a Priority of 2 so if the first one went down, they would connect to the secondary.

Failover and load balancing configurations are supported in Microsoft SQL Server installations where 2 or more management servers can connect to single SQL database. This is not supported in a standalone embedded database as a single embedded database cannot be connected to 2 management servers. However when using 2 different sites with SQL/embedded databases, they can be replicated (similar to clustering concept in Windows) to make them (virtually) a single database. Sites that are replicated are called replication partners. A partner is a management server on another site with a different management server and database. All sites that are set up as partners are considered to be in the same site farm. Load balance is supported between 2 or more sites when these sites are setup as replication partners.

Hi,

You should also understand what would be the consequences when any datacentre goes down?

1) If all the clients shifted to other site then how much bandwidth will be utilized?

2) Total how many sites you have and number of clients per sites?

3) Have you checked about GUP functionality.
