Hi PatrĂcia,
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:

If you run into any issues, please feel free to email our DSpace

Good luck,
- Tim

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.
