Since ZEO is mostly IO-bound. Decent Sun hardware I've worked with was not much slower or faster than decent Linux systems. If you have multiple ZEO servers consider using dedicated drives in case of a setup with high IO. But this applies to Linux as well..

I had compared packing on our previous generation SUN cluster with packing on a Linux server. The Linux server was about 4 times faster. But our system administrators have a very strong preference for SUN hardware. They told me that SUN has a much better IO subsystem and that this will become obvious when the system is under load. My personal opinion is that they can buy SUN support such that within a few hours all problems will be fixed by SUN while for Linux they can not get this level of support -- and therefore they prefer SUN. But, that's just my assumption (I do not have a proof). -- Dieter ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )

But our system administrators have a very strong preference for SUN hardware. They told me that SUN has a much better IO subsystem and that this will become obvious when the system is under load. that's what we've been told as well. especially because all applications on the server are I/O bound (zeo, postgresql, nfs). they told me as well, that the clustering/failover works perfect with roughly _zero_ downtime :) the san behind it is really powerful and should be able to reach 2x80MB/s easily. My personal opinion is that they can buy SUN support such that within a few hours all problems will be fixed by SUN while for Linux they can not get this level of support -- and therefore they prefer SUN. But, that's just my assumption (I do not have a proof). exactly - the cluster is f***ing expensive (RAM, SUN certification,...) but has almost no downtime (guaranteed). we finally managed to get the sun-cluster to test the setup (especially ZEO) and have the possibility to give it back and switch to LINUX in case it doesn't work. i'll keep you updated about our testing results. thanks so far jodok -- Dieter -- Although practicality beats purity. -- The Zen of Python, by Tim Peters Jodok Batlogg, Lovely Systems Schmelzhütterstraße 26a, 6850 Dornbirn, Austria phone: +43 5572 908060, fax: +43 5572 908060-77 smime.p7s Description: S/MIME cryptographic signature ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
[Zope-dev] zeo on solaris
hi, it seems like we're going to deploy a pretty big installation on a combination of solaris / RHEL servers. the data storage of our application is based on ZODB (ZEO) and PostgreSQL (with STORM) plus NFS for extfile handling. so far it's planned to deploy ZEO, PostgreSQL and NFS on a fully redundant SUN Fire 440 with Solaris connected to a Hitachi/Sun StorEdge 9990 SAN. i know ZOPE has/had some issues on Solaris (http://www.zope.org/ Members/glpb/solaris) we're talking about ZEO/PostgreSQL only... we guys at lovely systems don't have a lot of experience with solaris, who of you guys is running ZEO on solaris? how does it perform? we'd like to contract someone with solaris expertise in near future, volunteers - contact me :) thanks for your feedback jodok -- Simple is better than complex. -- The Zen of Python, by Tim Peters Jodok Batlogg, Lovely Systems Schmelzhütterstraße 26a, 6850 Dornbirn, Austria phone: +43 5572 908060, fax: +43 5572 908060-77 smime.p7s Description: S/MIME cryptographic signature ___ Zope-Dev maillist - Zope-Dev@zope.org http://mail.zope.org/mailman/listinfo/zope-dev ** No cross posts or HTML encoding! ** (Related lists - http://mail.zope.org/mailman/listinfo/zope-announce http://mail.zope.org/mailman/listinfo/zope )
