2 Configuring Nutanix Storage Pool and Containers
To use the cluster storage, you must configure a storage pool and containers within the pool. Create only
one pool consisting of all the disks in the cluster. Within the storage pool, we recommend creating
multiple containers for a logical distinction between the compute and management storage layers.
1. To configure the storage pool and containers, log in to the Nutanix Web Console. From the
Home drop-down menu, select Storage.
Figure 1 Nutanix Web Console
2. Click the Create Container link and click the plus symbol (+) under the STORAGE POOL section to
create a pool.
Figure 2 Create Container Wizard
5 Wyse Datacenter Appliance XC for VMware View
Figure 3 Creating Storage Pool
3. Type a name for the pool (for example, SP1) and use all unallocated disk space. Click Save. On the
Create Container page, to view additional settings, click the Advanced Settings button. The
recommended settings are as follows:
Replication Factor: 2
Reserved Capacity: 4096 GB (only for the “Compute” container that contains the persistent
virtual desktops)
Compression: Disabled
Delay: 0 minutes
Perf Tier Deduplication: On
Capacity Tier Deduplication: On (Post-Process)
4. Type a name for the management container. For example, “ds_mgmt, and click Save. Click +
Container to add another container for the compute or RDSH layer. Use the same advanced settings,
type a name (for example, ds_compute or ds_rdsh) and click Save. If you are using desktops and RDSH
on the same cluster, create an additional container for logical separation.
Figure 4 Overview
6 Wyse Datacenter Appliance XC for VMware View
Hyper-V Hypervisor and SMB Shares
SMB shares are used to store the virtual machine disks and settings files. The cluster name is the “host”
portion of the SMB share name. If not created during the Nutanix cluster setup, add a DNS entry for this
name and point it to the cluster IP address. The container names that you created earlier are used as the
share names. The resulting share name will be \\{cluster-name}\{container-name}. For example:
\\cluster\ds_mgmt.
By default, only the cluster hosts have access to the SMB shares. To change this, you must modify the
whitelist on the cluster. At a minimum, the IP address of the System Center VMM host must be added. If
you want all management hosts to be able to access, you can specify the network segment as opposed to
single IP addresses.
NOTE: The shares must be used only for storing VDI -related components.
To modify the Whitelist, go to the Nutanix Web Console, click the configuration wheel symbol in the
upper-right corner, and then click Filesystem Whitelists.
Figure 5 Filesystem Whitelists
Type the desired host IP address or network segment and click Add.

3 Installing vCenter Server Appliance
The deployment of desktop pools within VMware View requires that an install of the following VMware
components is completed successfully: VMware vCenter Server Appliance, VMware View, and VMware
View Composer and an associated SQL server VM. The VMware vCenter VM will be created using the
VMware vCenter Server Appliance. The VMware vCenter Server Appliance is a preconfigured Linux-based
virtual machine that is optimized for running vCenter Server and associated services. Visit the VMware
website for information on downloading version 5.5.0 and licensing.

8 Installing Remote Desktop Services Role on Windows
Server 2012 R2
RDS hosts are server computers that have Windows Remote Desktop Services and View Agent installed.
These servers host desktop sessions that users can access remotely. Within View, RDS desktop pools
provide users with desktop sessions on RDS hosts. When you create an RDS desktop pool you must
specify a farm. The RDS hosts in the farm provide the desktop sessions.
It is assumed you are familiar with installing Windows Server 2012. The screen shot here shows the last
task in installation where you are prompted for a password. After you type credentials, the host is
connected to the domain.

Note: For users to connect to an RDS desktop session, an RDS Desktop Pool must be created using
VMware Horizon View Administrator and an RDS Farm must be specified during the pool creation
process.

10 Deploying Virtual Desktop Master Image
10.1 Creating Template VM
Suggested on the basis of user types used by Dell.
NOTE: Solution is provided on the basis of using full clones for persistence (Standard provisioning) and
recommended disk format is VMDK. Ensure Master image is placed in the same container as the Desktop
pool for faster deployment
Provision a Gold image by doing the following:
Machine Creation Services - Master Image
1. Create Base VM (specify Disk size, Network, Memory, and so on)
2. Install Windows 8.1.
3. Add VM to the Domain.
4. Activate Windows 8.1.
5. Install VMWare Tools.
6. Install the VMware View 6.0.0 agent using the 32bit or 64bit versions as required.
7. Install any required application software including antivirus software and activate if required.
8. Optimize Windows 8.1 using VMWare Optimization best practices.
9. When all optimization tasks have been completed, open an administrator command prompt and type
ipconfig /release to release the IP address and shut down the VM.
10. If a pool of full virtual machine clones is being created; in the vSphere Client, right-click the VM and
select Template, and then click Convert to Template. A VM must be in template form in order for
VMware View to use the VM to create a pool of full clone desktops.
10.2 Optimizing Desktop OS
Ensure you use the VMWare desktop optimization script which can be downloaded from the VMWare
website which can be used to optimize desktop settings for a VDI environment including disabling
unnecessary services.
Windows 8.x Optimization
A new feature in Win 8.1 is Automatic Windows Maintenance, which is a feature of the dism tool that
checks the system and application for update compatibility and file integrity. By default, the system
scheduled task runs at 1 a.m. everyday, or any time after 10 min of idle time. When the system is
functioning, the tiworker.exe process consumes 100 percent CPU on any recently booted desktop
VMs, possibly overloading servers.

The administrator accounts cannot change the services because the services (idle time check and
automatic check) run as a SYSTEM. You must get SYSTEM rights to disable services.
You can still run the checks manually even if the services are disabled. You must have psexec.exe
(sysinternals) on the Master Image VM to fix this issue.
The following are the three scheduled tasks that must be disabled on your desktop template.
o psexec \\SERVERNAME -s schtasks /change /tn
"\Microsoft\Windows\TaskScheduler\Maintenance Configurator" /DISABLE
o psexec \\SERVERNAME -s schtasks /change /tn
"\Microsoft\Windows\TaskScheduler\Idle Maintenance" /DISABLE
o psexec \\SERVERNAME -s schtasks /change /tn
"\Microsoft\Windows\TaskScheduler\Regular Maintenance" /DISABLE
Turn off the Master Image and take a snapshot for reference.
