Notice
It is not recommended to store Exchange databases and transaction logs on the
same disk drive on the Windows Storage Server computer. This configuration
degrades disk performance and leaves the server vulnerable to data loss in the event
of physical disk corruption. Because corruption of the disk damages both the
Exchange databases and the transaction logs, a recovery operation can restore only
data from the last successful backup. All data stored after the last backup is lost.
Low-Capacity Network Configuration
As shown in Figure 1.1, a crossover cable connects the Windows Storage Server computer and
the Exchange server across a dedicated network in the low-capacity scenario.
Medium-Capacity Scenario
The medium-capacity scenario supports up to 750 mailboxes on one Exchange 2003 server.
