Table 3) Software Resources 4 PHYSICAL ARCHITECTURE Figure 1) Physical Architecture Overview. 4.1 NETWORK ARCHITECTURE The networks used for this test were dedicated 1Gb Ethernet. This network was split into three VLANs. One VLAN was for administrative/public traffic and CIFS access, and the other two were non-routable VLANs designed for storage and VMotion traffic. All virtual desktops were assigned an IP address using a DHCP server. The VMware ESX Server’s networking configur

Teaming ports and assigned to the public VLAN for access to CIFS shares and other network resource by the desktop virtual machines. The NetApp FAS2050HA has four 1Gb NICs. The four NICs were configured as two multi-mode VIFs. One VIF was specifically for VMkernel NFS traffic and was placed on the private, non-routable VLAN. The other VIF was for CIFS (Home Directories) and management traffic. This configuration allows for an Active/Active state with both failover and a degree of re

reboot of the storage controller at a future time. In the event the management/CIFS VIF needs to be created after the initial setup of the FAS2050, please refer to the Data ONTAP® Software Setup Guide for directions in rerunning the setup process for the storage controller. 1. For each NetApp controller, open NetApp FilerView® and click Network->Add Virtual Interfaces. 2. Name the new VIF. 3. Select the two network interfaces that will make-up the NFS VIF. 4. For Trunk Mode press t

Figure 4) FAS2050 NFS VIF setup – Modify virtual interface. The ESX hosts will need to be configured as well. For each ESX host, configure NFS connections to the storage controllers using a VMkernel port group. The network ports for this NFS VMkernel port group should be on a non-routable NFS VLAN. For each ESX host, the virtual switch for the NFS VMkernel should have two network ports that each go to different switches in the network. These two switches are stacked together with li

To configure the volumes that will contain the virtual machines perform the following steps: 1. For each NetApp controller, open NetApp FilerView® and click Volumes->Add to activate the Volume Wizard. 2. Click on Next to go to the Volume Wizard –Volume Type Selection screen. 3. Choose “Flexible” and click Next. 4. Enter the new Volume name and choose the language and click Next. 5.

You will next need to ensure that three of the volumes created on the storage controller are set as NFS volumes. In order to accomplish this, please perform the following steps: 1. From the FilerView menu, select NFS. 2. Select Manage Exports to open the Manage NFS Exports screen. 3. Click on the virtual machine production volume created in the previous step NFS export. 4. Grant the export Root Access permissions by clicking on Next and placing a green check inside the box. Then cl

4.4 INTELLIGENT READ CACHING VDI by nature is a read-intensive technology and is very bursty in nature. This can be exemplified by boot storms, login storms, and virus scan storms which all further increase the read-intensive and bursty nature of a virtual desktop environment. Traditionally, these challenges are addressed by increasing the cache for both ESX servers and storage devices, increasing the spindle count on the storage devices, and adding more storage devices to offset the t
