Virtual Desktop Infrastructure
Virtual Desktop Infrastructure (VDI) solutions from the TI Group give you all the benefits of virtualisation across your workforce desktops.
The TI Group’s product offering uses HP VDI which is an end-to-end solution based on the virtualisation-ready HP ProLiant and BladeSystem servers; HP StorageWorks storage; and HP Thin Client access devices.
Thin clients have no hard drive, allowing for more secure storage of data and applications on the server. In fact, keystrokes, mouse events and screen images are all that is sent between the client and server. This makes the device much more secure than a standard desktop or notebook computer.
With no hard drive, fan or other moving parts, thin clients have a much longer lifespan than standard computers and use significantly less power. Lower maintenance costs are another benefit as software application updates, virus scanning and patches can be executed on the server. Deployment costs are also reduced as thin clients can be remotely configured and do not need to be set up individually.
HP VDI with VMware View is based on VMware’s industry leading and proven virtualisation platform and HP Thin Clients that have been certified to work with VMware View Manager.
HP VDI with Citrix XenDesktop is the next generation, user-centric desktop virtualisation solution that provides a complete system for desktop delivery, with a broad range of user benefits.
HP ProLiant servers provide an excellent platform for a virtualised desktop infrastructure, with the potential for a large number of users on a single server and the ability to scale to a large memory footprint typically required for virtualised environments. This building block is required in all implementations and the choice of server determines what loads can be supported and how the risk is distributed in the environment. HP has a broad range of servers certified for VMware Infrastructure, Citrix XenServer and Microsoft Hyper-V.
Storage options and solutions available range from Direct Attached Storage (DAS) and Network Attached Storage (NAS) to Internet SCSI (iSCSI), and fibre channel Storage Area Networks (SAN).
Three key pieces of software are required to create an HP VDI solution:
• A virtualisation layer to host the virtual desktops. VMware ESX, Microsoft Hyper-V or Citrix XenDesktop.
• A desktop operating system installed into the virtualisation layer.
• A connection protocol to join the remote client and virtual desktop.
Microsoft’s Remote Desktop Protocol (RDP), Citrix’s Independent Computing Architecture (ICA) or HP Remote Graphics Software (RGS) may be used.
HP offers a comprehensive suite of management software tools powered by HP Insight Control software components.
Insight Control suite software delivers total control, maximum flexibility, and tangible savings for your ProLiant and BladeSystem infrastructure. Based on HP Systems Insight Manager and Insight software, Insight Control delivers comprehensive system health, remote control, vulnerability scanning and patch management, as well as flexible deployment and power management in one easy to install package for virtual and physical servers.
HP offers a choice of clients to meet the needs of a variety of deployments, but recommends the deployment of thin clients to serve as access devices. While it is possible to redeploy desktops as general access devices, optimised savings and efficiency can be achieved using stateless, low power thin client devices. HP Thin Clients serve as ideal access devices for VDI by providing enhanced security, easy manageability, high reliability and low TCO.
