- Determine how much data is already housed in your current infrastructure.
- Add to the figure above an estimate for the amount of data you might accrue over the next five years, and then double that number.
- Pick an iSCSI solution or some DAS hardware for a Sun Microsystems Open Storage system to address the capacity estimate from above and to provide room for growth. If you decide to use plain iSCSI, build a volume manager to share the data.
You should introduce a document management system (DMS) at the same time, or else your unstructured data will likely lose most of its value. You should create a volume with plenty of headroom for your database data, a volume with at least a year of headroom to migrate your legacy data to, and you should create a final volume to store the data for your DMS.
