Regardless of the network traffic requirements, always have at least two
physical network connections that are shared for a logical network to
ensure a single link failure does not affect the availability of the system. The
network should be designed so that the aggregate bandwidth, in the
event of a failure, is sufficient to accommodate the full workload.
The solutions contain layouts for the disks used in the validation of the
system. Each layout balances the available storage capacity with the
performance capability of the drives. There are a few layers to consider
when examining storage sizing. Specifically, the array has a collection of
disks that are assigned to a storage pool. From that storage pool, you can
provision datastores to the VMware vSphere Cluster. Each layer has a
specific configuration that is defined for the solution and documented in
Chapter 5.
It is generally acceptable to replace drive types with a type that has more
capacity with the same performance characteristic or with types that
have higher performance characteristics and the same capacity. It is also
acceptable to change the placement of drives in the drive shelves in
order to comply with updated or new drive shelf arrangements.
In other cases, where there is a need to deviate from the proposed
number and type of drives specified or the specified pool and datastore
layouts, ensure that the target layout delivers the same or greater
resources to the system.

Options for VSPEX End User Computing for VMware Horizon View available
on EMC Online Support.
The EMC VSPEX End User Computing solution supports a flexible
implementation model where it is easy to expand your environment as the
needs of the business change.
You can combine the building block configurations presented in this
solution to form larger implementations. For example, the 1,000-desktop
configuration can be realized by starting with that configuration, or by
starting with the 500-desktop configuration and expanding it when
needed. In the same way the 2,000-desktop configuration can be
implemented all at once or gradually by expanding the storage resources
as you need them.
The requirements stated in the solution are what EMC considers the
minimum set of resources to handle the workloads required based on the
stated definition of a reference virtual desktop. In any customer
implementation, the load of a system will vary over time as users interact
with the system. However, if the customer virtual desktops differ
significantly from the reference definition and vary in the same resource
group, you may need to add more of that resource to the system.
