Microsoft SQL Server 2012 Fast Track Reference Configurations using PowerEdge R720 and PowerVault MD3620i
7
Highly available reference architecture
For achieving high availability for the database, we recommend using Microsoft Database Clustering.
Using Microsoft clustering services, one database server is configured as the primary (active) server and
the second server is configured as secondary (passive). The secondary server should have exactly the
same configuration as the primary server. Since the database is active on a single server at any point of
time, the performance of the database on the primary server (active) is comparable to the single
server configuration (discussed earlier).
Figure 2 depicts the highly available fast track reference architecture, and Table 3 lists the
configuration details.
