It's being reported that Microsoft are dropping the Single Instance Storage component that was added to Exchange 2005. This feature enabled only a single instance of an attachment to be stored in the mail store. The Microsoft Exchange 2010 server store  will allow for the native compression of  all attachments.

If you an Exchange Administrator, I'd suggest you keep a close eye on the releases and upgrade notes for Exchange 2010 and particularly the potential increase in disk space for your environment.

Now lets map that across to the space saving features in Lotus Domino 8.5.1.  These are DAOS (Domino Attachment and Object Service), LZ1 compression within a database for file attachments, design compression for database design elements and a single copy template to ensure only 1 copy of design elements are stored on your server.

• DAOS has been seen to save our clients between 30-60% of disk space by storing a single copy of an attachment that has been distributed to multiple users on a Lotus Domino Server.
• LZ1 compresses ensures those single attachments which are not distributed to multiple users are compressed.
• Design compression can be used to compress design elements
• A Single Copy Template can be used to link all of your mail files to a single template..

With all of these features enabled you can reduce the total amount of storage your Lotus Domino Server utilises.

I know which platform I would choose if my disk space is constrained.. and lets not forget Lotus Domino is not a rip and replace solution..

As always the information in this post is correct at the time of writing.
