So, if your 3 million items take up 3TB of space, then you will need to ensure DSpace has access to 3TB worth of local (or mounted) storage space. You also need enough administrative overhead storage (inodes on Unix, index blocks or some such thing on Windows) to account for your millions of files. Likely this will not be a problem, but if you have a good estimate of the number of bitstreams (files) you expect then it wouldn't hurt to check. Also, most object types in the database have a unique identifier which is an SQL INTEGER. If you're using PostgreSQL then, for example, you can't create more than 2,147,483,647 Items. A few millions should not hit any hard limit. -- Mark H.

Hi Patrícia, DSpace itself uses the filesystem for storage. So you are only limited by your available file system space. So, if your 3 million items take up 3TB of space, then you will need to ensure DSpace has access to 3TB worth of local (or mounted) storage space. In the past (DSpace 1.6 and previous) there were some performance issues with DSpace when you stored millions of items. However, we've made some significant performance/scalability improvements to DSpace 1.7.x. So, at this point in time, we believe you will achieve good performance when storing millions of items (admittedly, most large DSpace installs just store hundreds of thousands of items, so we haven't done much testing with millions of items). That being said, to achieve optimal performance, you likely will need to ensure your server has appropriate memory and processing power. We have some hints on ways to performance tune your DSpace installation on our wiki at: * https://wiki.duraspace.org/display/DSPACE/SystemAdministrators * https://wiki.duraspace.org/display/DSPACE/HowToPerformanceTuneForDspace If you run into any issues, please feel free to email our DSpace Technology list: https://lists.sourceforge.net/lists/listinfo/dspace-tech/ Good luck, - Tim On 6/16/2011 5:00 PM, Patricia Coelho Ferreira Meneses da Silva wrote: Hi! Anyone know what the storage capacity of Dspace to version 1.7.1? Does anyone know the capacity of items that can be included in each collection? We want to store more than 3 million items and do not know if the system supports. Thanks. Patrícia Coelho -- EditLive Enterprise is the world's most technically advanced content authoring tool.
