Use Case Study: Using Active System For VMware Cluster Environment Configuration

maintain their own identities and act as two independent switches that work together, so they must be
configured and managed separately.
Downlinks to the I/O aggregators must be configured as LACP-enabled LAGs. LACP must also be enabled
on the storage distribution switches to allow auto-configuration of downstream I/O aggregators and to
tag storage VLANs on the LAGs, since they will be used to configure VLANs on the downstream switch.

connections are seen as
originating from a single
network device . This allows
connections from switches
with separate management
planes to be aggregated into
a resilient, LACP enabled
link aggregation.

Fabric B, LAN-Only Configuration
For this use case, Fabric B will be set up by Active System Manager for a LAN-only configuration. A LAN-
only network contains all other Ethernet traffic (but not iSCSI storage traffic). In this example, the LAN
distribution layer switches are a set of Dell Force10 S4810 switches that are configured as a stack.
Stacking allows these switches to be managed as a single, logical switch. Active System Manager will
only configure hardware within the Active Infrastructure blade chassis environment, thus the
distribution layer and above must be configured manually or by other tools. These switches connect
the downstream Dell Force10 PowerEdge M I/O aggregator switches in the chassis with the upstream
routed network.
