The Limitation of snapshots

Dear Support,

Our requirement detail as following:
Volume1：2 TB
Volume2：2 TB
Volume3：2 TB
Volume4：10 TB
Volume5：1 TB
Volume6：10 TB
Volume7：1 TB

For Volume1 and Volume2, we need keep not only snapshot take on everyday's 00:00 but also keep snapshot take on the latest day's 06:00, 13:00, and 18:00. In this case we need 10 snapshot volume for Volume1 and 10 snapshot for Volume2,am I right?

For Volume3, Volume4, Volume5, Volume6, and Volume7, we only want to keep the latest 3 day's snapshot. For example, today is 2011/11/24, we only want to keep sanpshot take on 2011/11/23 00:00, 2011/11/22 00:00 and 2011/11/21 00:00.

So, owing to the design of Open-E's snapshot function in the present day, we need at least 35 active snapshot volume (ps. We want all snapshots are automatically run by system).

But, the limitation of Open-E is 10 snapshots per LV and 20 active snapshots per System, because Open-E is based on e Logical Volume Manager (LVM), we thinks it is possible to increase this values of these limitation.

Could you please tell us how to increase these value?

Best Regards!
