The VMware Reference Architecture for Stateless Virtual Desktops on Local Solid-State Storage with VMware View 5

This document provides the reference architecture for Stateless Virtual Desktops with VMware View 5 on local solid-state storage. A stateless desktop architecture is ideally suited for standard desktop environments where the desktop image is consistent from user to user; however with proper application design can be used in broad use cases.

VMware View 5 allows specific placement of different types of disks to be re-directed, even to local storage, the I/O requirements on shared storage can be drastically reduced.

The VMware View 5 Reference Architecture for Stateless Virtual Desktops involves high-performing, solid-state drives within a physical host to offload the majority of desktop virtualization IOPS needed, while providing a stateless desktop virtualization design for planned and unplanned downtime.

This use of local solid-state drives (SSDs) is a completely new approach to desktop virtualization storage. SSDs are critical to achieving a low per-desktop cost because they remove the need for operating system and application storage requirements on the SAN. By decentralizing these storage needs, the desktop environment for CPU and memory resources scales linearly, with extremely low latency.

The simplicity of the architecture that is enabled by View 5’s tiered storage capability allows for a new era in the evolution of desktop virtualization cost modeling.

Increasingly, organizations are turning to virtual desktop technologies to address the operational and strategic issues related to traditional corporate desktop environments. VMware View 5 provides not only a virtual desktop environment that is secure, cost effective, and easy to deploy; but now can also provide comprehensive storage flexibility.

VMware View 5 modernizes the desktop experience to deliver private cloud capabilities to users for a consistent experience across the global enterprise. This Desktop-as-a-Service model is possible with unmatched scalability in a stateless design. The challenges of traditional desktop administration, especially at scale, range from lost laptops with corporate data, security issues related to viruses or hackers, or simply ensuring IT resources can maintain a service level agreement (SLA) appropriate for specific end users. In addition to the challenges of operational management, IT must also consider the implication of broader system-wide issues such as compliance, corporate governance and business continuity strategies. This whitepaper provides full descriptions of the test environment as well as performance metrics captured during test validation.

Video - Provisioning Virtual Desktops with VMware View 5.1 and VAAI

Cormac Hogan: Although this feature is a Technology Preview in View 5.1, it is another cool storage feature of the release. View desktops deployed on VMware's linked clone technology consumes CPU on the ESXi hosts, and network bandwidth when they are deployed on NFS datastores.

With this new Native NFS Snapshot feature via VAAI (vSphere Storage APIs for Array Integration), customers can offload the cloning operation to the storage array, minimizing CPU usage and network bandwidth consumption. Once again this enhanced VAAI functionality was introduced in vSphere 5.0 specifically for VMware View.

This feature requires a VAAI NAS plugin from the storage array vendor. Once installed and configured, customers will be able to use a storage array vendor's own native snapshot feature for deploying View desktops. Selecting this new desktop deployment method can be done via standard work-flows in View Composer.

Technical Paper - Multipathing Configuration for Software iSCSI Using Port Binding

This paper provides an overview of how to enable vmknicbased software iSCSI multipathing, as well as the procedure by which to verify port binding configuration.

http://www.vmware.com/files/pdf/techpaper/vmware-multipathing-configuration-software-iSCSI-port-binding.pdf

Configuring vmknic-based multipathing for the software iSCSI adapter will help vSphere users enable failover at the path level as well as balance I/O traffic between the paths.

Technical Paper - Storage Protocol Comparison

The objective of this white paper is to provide information on storage protocols and how they interoperate with VMware vSphere and related features. Not all supported storage protocols are discussed. Some notable exceptions are ATA over Ethernet (AoE) and shared/switched SAS. However, the protocols that are included in this paper are the ones that VMware is most frequently asked to compare.

http://www.vmware.com/files/pdf/techpaper/Storage_Protocol_Comparison.pdf

VMware frequently is asked for guidance regarding the best storage protocol to use with VMware vSphere®. vSphere supports many storage protocols, with no preference given to any one over another. However, many customers still want to know how these protocols stack up against each other and to understand their respective pros and cons.This white paper looks at common storage protocols from a vSphere perspective. It is not intended to delve into performance comparisons, for the following two reasons:

The Performance Engineering team at VMware already produces excellent storage performance white papers.
Storage protocol performance can vary greatly, depending on the storage array vendor. It therefore does not make sense to compare iSCSI and NFS from one vendor, because another vendor might implement one of those protocols far better.

If you are interested in viewing performance comparisons of storage protocols, the “Conclusion” section of this paper includes links to several such documents.
