I am reading a portion of the Exchange 2010 documentation-specifically the Exchange 2010 Mailbox Server Role Design Example (see URL) below
A part of the paragraph immediately after the "Example values for determining actual mailbox size on disk" table, states:
"...In this environment, each user will consume 2.25 GB of disk space. This solution will also leverage 1TB disks in a JBOD configuration; therefore the maximum database size is 667 GB....."
I just need some help in understanding how "the maximum database size is 667GB" came about(was derived) within the context of the example!
