VDI & Types of Desktops

Dear all,


Today we will be discussing about VDI and types of desktops. Please see more information as you read through this post.


Huawei desktop cloud solutions can provide various types of desktops, including:


  • full copy desktop;

  • linked clone desktop;

  • Full memory desktop;

  • HD graphics desktop.


FULL COPY DESKTOP SOLUTION

Full copy desktops use the virtualization technology and remote desktop delivery technology. In a desktop cloud center, servers and storage devices are virtualized into elastic virtual hosts by using virtualization technology. When a full copy desktop is created, the system assigns an independent system disk to the full copy desktop and totally copies a VM template to the system disk. In this manner, each desktop has its own system disk and user data disk.


All VMs are isolated from each other. Users can have personalized desktops and use various peripherals. All these contribute to superior user experience as if PCs were being used. Users can modify VM specifications based on the workload. Each user has a dedicated VM, and the system disk and data disk are loaded from a centralized storage device.


Users can remotely log in to VMs by using TCs or SCs. VMs use the industry-leading HDP protocol that requires lower bandwidth to deliver virtual desktops to users.


FULL MEMORY TOP SPEED DESKTOP SOLUTION

Many virtual desktop infrastructure (VDI) storage performance computers have sound performance when predicting users' work. However, Windows lacks efficiency when it is started and logged in to. When a large number of Windows OSs are started or logged in to at the same time, startup storms or login storms will occur on VDI systems. Full memory VMs come into being under this background. Full memory VMs use the high I/O read/write performance of memory to convert the storage read/write of virtual desktops to the read/write of memory, solving the storage IOPS bottlenecks of VDI systems.


Using IOTailor technologies, full memory VMs deduplicate and compress the VM base disk data and then stores the data in memory in full amount, achieving high read/write storage I/O performance. When users read or write system disk data, part of the memory is allocated as delta disks temporarily. The system disk for each user (that is, drive C) is the combination of the shared base disk and the delta disk. The data stored in memory cannot be persisted in real time, so that VMs will be restored to the initial status after being shut down or the server hosts are restarted. Full memory VMs use memory as the system disk media of user VMs, improving the I/O performance of OSs on system disks. In addition, using the memory-based online deduplication and real-time compression technologies (IOTailor technologies for short), full memory VMs deduplicate data on the system disks of user VMs, reducing the storage space occupied by data.

 

LINKED CLONE DESKTOP SOLUTION

The major difference between linked clone desktops and full copy desktops lies in the system disk. The linked clone technology allows multiple VMs to share the same system volume of the parent VM, which is also known as the base disk. Each copied VM has a delta disk to record changes (such as temporary data, customized configurations, and temporary customized applications) to the base disk. The customized configurations are saved in C:\User (Windows 7) or C:\Documents and Settings (Windows XP) and the customized applications are saved in C:\Program Files. The base disk and the delta disk constitute the system disk (that is, drive C) of a VM. Restoration policies can be configured for delta disks. The restoration policies can be set to manual restoration and restoration upon restart. Data on the delta disk is automatically deleted each time the base disk is updated.


Because the base disk is shared by many desktops, it must offer high read performance. The Huawei virtualization platform provides the iCache acceleration function for the base disk of a linked clone. With this function, the hot data on the base disk is cached into the local disk or memory of a server. This reduces impact on shared storage performance.


FusionAccess supports roaming of personal configuration data and unified user data storage. A user can use the same user configuration file to log in to different servers. Linked clone desktops can be used with Windows roaming configuration.


HD GRAPHICS DESKTOP CLOUD

High definition (HD) graphics are 3D applications that require support from graphics cards. HD graphics include applications that comply with the DirectX or OpenGL standard. Now, desktop cloud technologies for common OA become mature. The development of HD graphics desktop cloud technologies speeds up. Manufacturers increase R&D investment and provide related solutions. Solutions include Microsoft RemoteFX, VMware virtual shared graphics acceleration (vSGA) and virtual dedicated graphics adapter (vDGA), Citrix HDX 3D Pro and NVIDIA graphics processing unit (GPU) hardware virtualization.


Huawei FusionCloud Desktop Solution provides 3D graphics processing capabilities to end users using HD graphics desktop cloud. Users can use various HD graphics software, including computer aided design (CAD), geographic information system (GIS), 3D game software and omnimedia video editing software. The Huawei FusionCloud Desktop Solution meets the graphics processing requirements from different industries such as engineering, manufacturing, oil, automobile, healthcare, games and media.
