Equallogic PS6000 SAN snap shot space warning

Question

I have a 350 gb volume and I have a snapshot schedule set up every 12 hrs.

In use space is 232 gb free space is7.16 gb and unreserved is 110.83 totaling 350 gb

My snapshot in use is 239.18 and borrowed is 494.14 gb and the in use warning is set to 75% and snap shot reserve is set to 100 % of the volume

It looks like the snapshots are taking up 719 gb of space when the size of the actual volume being used is only 232 gb

Any help is appreciated, I contacted support and they were useless, I sent them logs and they remoted into my SAN and were no help.

I have removed the borrow space option and deleted my snapshots and recreating my schedule to start over.

My in use volume space is at 232 gb

My snap shot space is now at 741.46 gb

If I have 6 snap shots max schedule at every 12 hrs can i assume if its working properly it will not take up more than 5oo gb if the actual volume is only 232 gb?

Thanks Don I am on v 7.0.1

OK so what I was experiencing before with it wanting to take up 700 gb at 400% is not normal?

I am hoping that making these changes and starting over it wont want more that 100 % because each snapshot after the initial one should only include the changes on the volume.

Yes I kept bumping the % up because I previously had it set to borrow space and it kept wanting more.

The volume is an exchange volume so I know from 12 pm to 12 am the size is not going to grow to much so the second snapshot at midnight should be minimal or at least not double the space.

Thanks for explaining this Don, I ran my first snap shot with the new settings and looks like its was 181 gb the second one went at midnight and is now at  328 gb. we will see how much space the one at noon today takes up.
