Deployment of VDI

Can VDI deployments benefit from high-density hardware? The answer to the VDI deployment question is not simply "sometimes", and the answer to the VDI deployment question depends on the problem to be solved. Deploying high-density servers in VDI is likely to increase the cost of a single desktop, and it does not support more advanced multimedia requirements, so you need to rethink your storage strategy. However, if a large number of virtual desktop users must be supported and the data center space is limited, the additional cost of deploying high-density hardware in VDI is obviously worth it. VDI deployment Compared with traditional servers, high-density servers can provide more computing power in a smaller physical space. For example, the 2U-high PowerEdge FX product family can support up to 128 compute cores. VDI deployment vendors also provide high-density switching, so that there are as many as 132 connection ports with a speed of 40G on a switch (this may sound more like converged infrastructure, and some high-density hardware does fall under CI, but they are not mutually exclusive). When discussing high-density virtual desktop VDI deployment, it refers to deploying multiple virtual machines in VDI mode on a host. It is logical to assume that using high-density hardware to support many desktops can upgrade virtualized VDI deployment to a new high-density level, but this is not necessarily the case. There are some commercial systems used to meet the hardware requirements of VDI, but these systems are mostly pre-packaged rather than specially designed. Dell's DVS simple device is an example. The Desktop Virtualization Solution (DVS) package is based on Dell's standard PowerEdge R720 or T620 servers and bundled with Citrix XenServer or Microsoft Hyper-V and VDI management tools. It is reported that the device can support 129 users at most, and it is easy to deploy more devices to support more users. Other VDI devices include VMware's fast desktop device based on VMware Horizon View, Vertex VDI device of Tangent Company and vSTAC VDI device of Pivot3 Company. Because DVS relies on standard servers, it is not customized or specially designed to distinguish it from traditional servers. Redundancy such as N+ 1, automatic failover, load balancing, desktop configuration and desktop image management can all be realized by software tools. VDI instance support is directly related to computing resources, but VDI hardware requirements depend on the complexity of desktop mirroring and layering functions such as personalization and application virtualization. The above factors make it a considerable challenge to determine the exact amount of resources required for each desktop instance and the number of instances that a given server can support. This emphasizes the necessity of testing in a well-planned PoC project and a limited deployment environment (such as selecting a workgroup or department) before deploying VDI on a large scale.
