RAM and the size of your harddrive are limiting the usability filestorage. Very large ZODB sizes are between 10-40GB. Since storages are pluggable you can spread storages over multiple disks and mount them into your Zope instance. -aj

You can? Is there a HOWTO on this topic. It seems like an interesting way to seperate content for different vhosts, so a corrupt ZODB for one website won't bring down the others as well. TIA, John Ziniti

For this, the easiest thing is to run multiple Zope instances. Each instance maintains its own products, ext. methods ZODB store(s), etc. HTH, Dylan

Zope 2.7's config file allows you to set a FileStorage's mount point in the object tree. The inspiration for this is DBTab, and you can use it in current Zopes. --jcc -- "My point and period will be throughly wrought, Or well or ill, as this day's battle's fought."

We have an application that has about 2 million objects in the ZODB and about 700,000 objects in a single ZCatalog and zope has been working fine. Our cache size is 10000. Jonathan Hobbs SBS -

There are various limits, almost none of them Zope-specific. Older Python (2.1.3 on Windows) will limit you to 2 gig. Your OS and/or filesystem may limit file size of Data.fs to anywhere from 2G to several TB. You can get around this with DirectoryStorage or DBTab. Your OS and/or filesystem may limit filesystem size similarly. And you cannot store more data than you have disk space. There are some application factors: Administration of lots of objects in the wrong UI can suck tremendously. Regular folders need to become BTreeFolders to handle more than a few thousand objects. If you're planning a TB+ ZODB, perhaps you will want to test first to see how Zope handles it. Otherwise, it's probably not a problem. --jcc -- "My point and period will be throughly wrought, Or well or ill, as this day's battle's fought."

When your Python is not compiled with large file support, the limit will be 2 GB. Otherwise, you will not reach the theoretical limit (2**64 bytes, something like 10**18 bytes). Before that you will reach a practical limit: the ZODB keeps an index in RAM which maps OIDs to file positions. This means, your RAM requirement grows linearly with the number of objects in your FileStorage. -- Dieter
