Running out of space, planning for future growth, Help?

Hi,

We are currently planning for a new Structure to be implemented... But I am stock on what the best approach may be.

Having spent some time on Miscrosoft documents looking for answer, I am having to hope for a solution on this forum...

If you have time to spare, I would appreciate your help.

Our current set up, 4 Site collections (one per jurisdictions)...

First problem, sharing and collaborate between these site collections.... It can't happen...??

Second problem... 2 of our 4 collections are maxed out at just under 200Gb. I undertstand that it is not recommended to go beyond... in Fact when we did, the whole Site ran very slow...

So we are contemplating Re-creating our Sharepoint environment, and create a Site Collection per CLient, to allow for growth, per client, But this seems a little extreme, especially when we have way more than say... a few clients....

So whats best practice here....

We have various teams working in different Jurisdictions, sharing, collaborating on each clients...

The ideal scenario would be a single Team Site Collection, but a Sub Site per Client, but we would go way above the 200Gb Limit...

Where do we go from here?

Anyone experienced this ? Any suggestions?

Apologies if this topic has been covered...
