1 INTRODUCTION TO VMWARE VIEW

Built on VMware’s industry-leading virtualization platform, VMware® View is a Universal Client solution that lets you manage operating systems, hardware, applications and users independently of each other, wherever they may reside. VMware® View streamlines desktop and application management, reduces costs and increases data security through centralization, resulting in greater end user flexibility and IT control. VMware View enables customers to extend the value of VMware Infrastructure and virtual desktop infrastructure (VDI) environments to encompass not only desktops in the datacenter but also applications and the delivery of these environments securely to remote clients, online or off, anywhere.
VMware View transforms the way customers use and manage desktop operating systems. Desktop instances can be rapidly deployed in secure data centers to facilitate high availability and disaster recovery, protect the integrity of enterprise information, and remove data from local devices that are susceptible to theft or loss. Isolating each desktop instance in its own virtual machine eliminates typical application compatibility issues and improves and delivers a more personal computing environment.

2 ABOUT THIS GUIDE

This deployment guide provides a detailed summary and characterization for designing and configuri ng a NetApp FAS2050HA storage system for use with VMware View and Linked Clones. It describes a validated configuration for a 1000 user workload where 500 desktops are in persistent access mode and 500 users are in non-persistent access mode. This guide can be easily scaled up for larger deployments by simply increasing the number of servers, storage controllers, and storage needed.
The configuration presented was validated in accordance with a re commended architecture as defined in the VMware View Reference Architecture: A Guide to Large-scale VMware View Deployments guide is intended to offer Systems Architects and Administrators guidance with the configuration of a NetApp FAS2050HA storage system for use with such VMware View based environments. The information provided in this guide also can be helpful to anyone looking to deploy VMware View with Linked Clones using a NetApp FAS2050HA. In addition, due to all NetApp FAS storage controllers having the same feature and management interface consistency with Data ONTAP®, all of these guidelines can also be directly applied to entry-level and enterprise-class NetApp FAS storage controllers. All of the NetApp best practices applicable to this solution configuration are documented in NetApp’s TR-
3428: NetApp and VMware Virtual Infrastructure 3 Storage Best Practices, TR-3705: NetApp and VMware View Solution Guide and TR-3505: NetApp Deduplication for FAS Deployment and Implementation Guide and have been used in the creation and validation of this environment.

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 configuration consisted of ten 1Gb Ethernet Controllers (or NICs). Two were configured as NIC Teaming ports for NFS traffic and assigned to a pre-defined VMkernel port used for NFS access with a pre-defined IP address on the non-routable VLAN (i.e. 192.168.1.x). Two NICs were configured as NIC Teaming ports for VMotion traffic and assigned to a pre-defined, VMotion enabled VMkernel port with a pre-defined IP address on another non-routable VLAN used solely for VMotion traffic (i.e. 192.168.0.x). Two NICs were configured as NIC Teaming ports for the Service Console and assigned to the administrative VLAN. The last four NICs were also configured as NIC
5
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 redundancy in the NFS environment. The two switch ports for the NFS traffic on each storage controller were assigned to a private, non-routable VLAN previously configured and the multi-mode VIF was assigned a pre-defined IP address on this VLAN (i.e.
192.168.1.x). In addition two additional NICs on the public VLAN (with each residing on separate switches) are configured into a multi-mode VIF for CIFS traffic. This configuration can either be done in the Data ONTAP GUI or from the Data ONTAP service Console. Additionally, the multi-mode VIF configured for NFS traffic was also assigned an alias IP address to allow for mounting the NFS datastore to the ESX hosts with different IP addresses to increase throughput and redundancy of the NFS IP link.
Since the Cisco 3750s used in this configuration support cross-stack Etherchannel trunking, each storage controller requires only one physical connection for NFS traffic to each switch. The two ports were
ombined into one multimode LACP VIF with IP load balancing enabled. c

Shown below is a step-by-step of how to perform the network configuration for the NFS VIF in FilerView®.
NOTE: In accordance with NetApp best practices for storage controller configuration the creation of the management/CIFS VIF was necessary in order to have redundant NICs for management. The creation of the management/CIFS VIF should be done during the initial setup of the FAS2050 in order to avoid a
