Figure 1.1 Recommended Configuration for the Low-Capacity Scenario
Low-Capacity Disk Drive Configuration
In the low-capacity scenario, the Exchange databases are stored on a RAID-5 volume that spans
four disk drives on the Windows Storage Server computer.
File transfers are most efficient when Exchange databases and transaction logs are stored
separately, as shown in Figure 1.1. Store Exchange databases on the Windows Storage Server
computer, and store transaction logs on the direct attached storage (DAS) drive on the Exchange
server. Physically separating the transaction logs and databases adheres to Exchange best
practices and ensures that the writing of transaction logs does not interfere with the writing of
the databases.
