Re: How to implement HA architecture?
Thanks you all! I learned a lot from you guys. But I still got something to confirm. What I have: 1) 4 physical machines MS Windows OS(2 for Mid-tier, 2 for ARS); 2) One physical F5 device; 3)One Oracle RAC hosting DB for ARS. My customer is primarily using Web client. Q1)Can I create two farms on one single F5 device? one for Mid-tier; one for ARS. Does this configuration have HA capability for ARS? I mean if one ARS server down, the whole system is still working. Q2)Does MS cluster provide one single entry and HA function for two ARS servers? I mean two ARS servers within one server group. If one ARS server down, MS cluster will switch to another ARS server. And this server will still pick up Administrative Operations, Escalation, Reconciliation, etc... Does MS cluster service equal to a F5 device from HA point view? I will post F5 device model that you may know. Best regards! Martin 2009/12/5 Kelly Deaver kdea...@kellydeaver.com ** You may find this presentation handy as well.

You can create many farms on a single F5 (of any type you choose). If one arserver is down, things should just keep working as if nothing were wrong.

DSL 2.1 - ITSM 7.0.3 patch 7 - DSL Performance issues
All, Has anyone run into issues where search menus and other drop downs just hang because of inefficient SQL queries? A lot of the menus (the Product File Lookup form search menu for File ID for example), does a LIKE query against a huge number of records. The thing is, this is OOB with the DSL data load provided by BMC. Is there a way to optimize these menus without a lot of custom work? I guess I can always reach out to the DBA to see if he can work some magic on indexes. I do see that the field being searched on is indexed on the form, but obviously it is not helping.

Re: How to implement HA architecture?
There are many other solutions that are just as viable. The concept is that of a reverse proxy and/or a load balancer. BigIP has gone to lengths to: 1. add bells and whistles to their devices to make the configuration, administration, and maintenance as easy as possible. 2. choose the best hardware for the job at hand They are in essence the 800lb gorilla in this arena. The BigIP LTM's run on a Linux kernel; they used to run on a BSD kernel. There are a number of open source programs that implement similar functionality and there are other vendors that offer competitive products: Open Source: squid, varnish, ... Proprietary: Cisco ACE, Radware AppDirector, Barracuda Load Balancer, ... The open source offerings are generally limited to web traffic (http/https). There is a lot to be gained by the hardware in these types of devices (performance, scalability, reliability, capability) and as such they are generally marketed and sold as network appliances, not a software solution; an area that the open source model does not address very well.
