system is provisioned from the pool to present to the vSphere
servers as a VMFS or NFS datastore.
Thirty-two NL-SAS disks (shown as 0_0_8, 1_0_3, 1_1_0 to 1_1_14,
and 0_2_0 to 0_2_14) in the RAID 6 Storage Pool 1 are used to
store user data and profiles. FAST Cache is enabled for the entire
pool. Ten LUNs of 3 TB each are provisioned from the pool to
provide the storage required to create four CIFS file systems.
Disks shown as 1_2_10 to 1_2_14 are unbound and not used for
testing this solution.
Disks shaded gray are required and are part of the core storage
layout.
If multiple drive types have been implemented, FAST VP may be enabled
to automatically tier data to balance differences in performance and
capacity.
VNX shared file systems
Four shared file systems are used by the virtual desktopstwo for the
VMware View Persona Management repositories and two to redirect user
storage that resides in home directories. In general, redirecting users’ data
out of the base image to VNX for File enables centralized administration,
backup and recovery, and makes the desktops more stateless. Each file
system is exported to the environment through a CIFS share. Each persona
management repository share and home directory share serves 1,000
users.
High availability and failover
This VSPEX solution provides a highly available virtualized server, network,
and storage infrastructure. When implemented in accordance with this
guide it provides the ability to survive single-unit failures with minimal
impact to business operations.
EMC recommends configuring high availability in the virtualization layer
and automatically allowing the hypervisor to restart virtual machines that
fail. Figure 29 illustrates the hypervisor layer responding to a failure in the
compute layer.
Figure 29. High availability at the virtualization layer
By implementing high availability at the virtualization layer, even in the
event of a hardware failure, the infrastructure will attempt to keep as
many services running as possible.
