Designing for High Availability 31
Design for Direct-Attach SAS Configurations
Table 3-7 summarizes the recommended network requirements for a Direct-
Attach SAS-based configuration for a Hyper-V Host Cluster. It is important to
note that this is only guidance, and actual deployment configuration will vary
based on the existing infrastructure.
* Scale the number of network ports based on the number of VMs and
workloads. Distribute VMs across the associated virtual networks based on
bandwidth requirements.
Figure 3-3 provides a sample configuration of the infrastructure and
highlights the need for isolating the traffic for management, storage, and
workloads running within the virtual machines.
