[ZODB-Dev] Advice on whether to run relstorage database and Zope on different servers
Hi, We've been successfully running Plone 3.3 + Zope 2.10 + Relstorage + MySql for a couple of years now. We're running low on memory on our existing server (which has numerous other services on it) and will soon need to deploy an additional Plone 4.1 + Zope 2.13 + Relstorage + Mysql environment. We've been using virtual environments since September. For the purposes of this discussion please assume we don't have the option of increasing the memory on our existing server and so need to add a new one.Some questions I'd really appreciate your help with please: * I'm familiar with enterprise environments where you would have an app server and a database server but are there any advantages to putting Zope and MySQL on different servers? * I'd expect a performance hit if we run Zope + MySQL on separate servers but is this hit manageable? * Can we put anything in place to mitigate this? * Would you simply recommend having the existing mysql + zope on one server and the new mysql + zope on the other?

Re: [ZODB-Dev] Relstorage and ZEO
OK thanks. To confirm you can have a cluster of Zope instances all using relstorage to connect to the same database. This negates the need for ZEO as the database handles the multi-threaded data access. +-+ +-+ |Zope Server 1| |Zope Server 2| +-+ +-+ | Relstorage | | Relstorage | +-+ +-+ `-..-' `. _.-' `-..-' ++ |Database| ++ Shane Hathaway wrote: Alan Runyan wrote: Ask this question on either Zope/Plone mailing list. My understanding about relstorage is that each Zope application client uses relstorage. There is no ZEO server in the mix. Is that correct Shane/others? Yes. ZEO is not needed when you use RelStorage.

[ZODB-Dev] Relstorage and ZEO
Hi, I'm working on a project to migrate a number of sites to a content management system. We finished our evaluation period and chosen Zope / Plone. I'm new to both products and would like some advice about our initial deployment. The impression I get is that using both ZEO and Relstorage are recommended. My question is whether you'd recommend using them together or not. The sites get up to half a million requests a day (not page impressions) and we're planning on using Apache (mod_cache) and CacheFu for caching.
