SAP Content Server HA and load balancing

Good morning experts.

I am a Basis Architect and working towards setting up our SAP environment to support near Zero downtime. I have successfully setup our SQL Server databases, NW Instances and even TREX to support that model.

I am looking for some suggestions on how to setup HA on the SAP content server. Currently we are moving our SAP content (attachments to PO/Invoices, Marketing attachments etc. from our ECC and CRM systems to SAP content Server. Also archiving stuff is moved to the content Server. This makes the Content Server critical for business. Therefore any downtime is an outage for business.

SAP does not have a HA model for SAP content server(at least I could not find any information). the maxDB part does support failover clustering but for the Content server IIS services, I could not find any information. I am looking for a multi node HA model where I can achieve High Availability for incidents, like if the server crashes, there is another instance it can automatically failover to. Also during any maintenance I can work node by node without causing any outage.

we have a VMware virtual environment on windows. I am open to suggestions using the technologies provided by VMware and supported by SAP.

I know I can start using a non SAP utility to manage content like Opentext, IBM Content management, but these solutions are like a blackhole. Once you get into them, there is no way out unless you are willing to spend millions. Also of-course SAP Content Server is free and we have a single point of support. 😊.

Yogesh

    Hi Yogesh,

    For Content Server HA setup on Windows you may refer below SAP note

    Note 1726396 - Integration of SAP MaxDB/liveCache 7.8/7.9 into MSCS

    For non-SAP applications which are relevant for Content server to operate like IIS please refer below blog from Microsoft

    http://blogs.msdn.com/b/clustering/archive/2009/06/01/9674799.aspx

    Hope this helps.

    Regards,

    • Hi -

      We actually ended up with a physical MSCS cluster for MaxDB at the database level. And at the application server level, we have two VM's with IIS and Content Server installed on each being load balanced by an F5. We don't have true HA at the application server level, but in case one of the application servers goes down we can temporarily use the other available application server until the other comes up. Using VM's at the application level makes the recovery/build process easier if needed.
