Designing for High Availability 27
Dell offers a wide array of servers that have been specifically built with the
goal of being able to host virtualized workloads. These servers offer support
for large amounts of physical memory, large numbers of I/O slots for both
network and storage, and a minimal power footprint. For a full list of servers
that Dell recommends for virtualization, go to www.dell.com/servers.
Design for iSCSI-Based Configurations
Table 3-5 summarizes the recommended network requirements for an iSCSI-
based configuration for a Hyper-V Host Cluster:
* 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 3-1 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.
