Re: Load Balancing OAS: Kemp vs F5
Date: Thu, 27 Mar 2008 07:55:06 -0500
I've worked a lot with both Cisco and F5 load balancers and like them both. I find the F5 to be a bit easier to configure for "normal" OAS admins as the Cisco device seemed to only be configurable by people with a lot of networking background. Unfortunately for me, most of the sites I've worked at have network admins that don't have a good grasp on Oracle's requirements (despite my attempts to teach). So, I'd have to recommend the F5. I've never heard of the other device you mention and as I've worked quite a lot with sites doing OAS clustering and load balancing, that's saying something. I've seen Nokia, Radware, Cisco, F5, Alteon, NetScalar (Now Citrix, I think), and Sonic Wall.
The information on the following URL may also be of interest. Oracle
doesn't officially "certify" any load balancers, but they have at least
published this list of tested devices.
YMMV, but chosing from this list may get you at least a community of
people that could help support you on specific issues. I know F5 and
Oracle have jointly published a number of whitepapers on configuration
details. Also, you'll find some indications on how well Oracle supports
certain devices by whether or not they're listed in Appendix A of the
Install guide for OAS 10.1.2 (and possibly other versions, this was just
the version at my fingertips):
http://download.oracle.com/docs/cd/B14099_19/core.1012/b13998/sampleconfig.htm (Note: FWIW, the F5 sample config is really quite old--things changed drastically when they jumped from version 4.x to 9.x).
Good luck! I'd personally like to know what you end up choosing and why and what your implementation experience is like when you get that far.
