A dedicated network between the Exchange server and the Windows Storage Server computer that uses a crossover cable A 10/100 Ethernet hub connects the Exchange server, the Windows Storage Server computer, the domain controller, and client computers 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.
