What's the point of using RBS when you are still restricted to 200GB content DB limit? I don't understand this thing.
Secondly this looks like recommended limit, right? Because SharePoint won't stop working all of a sudden if you go over this limit?
200 GB is the suggested maximum limit to simplify your life and provides databases in manageable chunks. i dont think any body likes having to restore a 4TB database or BLOB data since it takes a while.Backup & Recovery make the things hard for administrators. If you deciede to go beyond the 200GB limit then follow things you have to check.
- Disk sub-system performance of 0.25 IOPS per GB. 2 IOPS per GB is recommended for optimal performance.
- You must have developed plans for high availability, disaster recovery, future capacity, and performance testing.
- Plus you have to make sure if you are spending more or less on hardware coste etc.
200GB is the recommended size, but it can go upwards of 4TB. I imagine they still recommend not to go over 200GB in an RBS scenario incase you have to internalize the blobs. You wouldn't want to have a 3TB blob store and have to internalize it back into SQL server. Suddenly you have a mess on your hands.
When the DBs get that large, back up and recovery becomes more time consuming.
