Dell Integrated Systems for Oracle Business Analytics (DISOBA) – Owner’s Guide 1.0
3.2.2 S6000 VLAN and Port Channel Configuration
Though it is typically recommended to have dedicated switches for the Oracle database’s
public and private traffic, in this pre-integrated solution, the S6000 switches are used for
handling both types of traffic. The switches are however pre-configured using Dell and
Oracle’s best practices by segregating the public and the private traffic using VLANs. Using
one of the S6000 switches as an example, Figure 9 shows the VLAN and port channel
configuration on the S6000 switches.
S6000 VLAN and Port Channel Configuration
Thus, the ToR S6000 switches are configured to provide secure and segregrated
connectivity for both public and private interconnect traffic.
3.2.3 S6000 VLT Domain Configuration
Virtual Link Trunking (VLT) is a proprietary aggregration protocol by Dell Force 10 that is
available in its enterprise-class network switches. VLT provides a loop-free environment by
presenting two physical switches as one logical switch while not losing bandwidth for the
devices connecting to it over two links.
Figure 10 shows the VLT Domain configuration across the two S6000 switches
implemented in the DISOBA solution rack. Four FortyGigE ports are used for VLTi trunking
to provide adequate bandwidth for any customer network connecting to it. The
management port is used for the VLT backup link. Port Channel 1 on both the S6000
switches that connect to the S60 management switch are configured as VLT peer LAG to
provide 20GB of bandwidth and high availability.
