17 Quad Display KVM Extender Host 3.5 STEP 5: Connect a zero client to the DXT-H4 1. Install and power up a zero client. If you are not sure how to do this, see the relevant Amulet Hotkey user manual or Quick Start Guide for the zero client. When the zero client is on, you are ready to establish a new PCoIP session. The zero client connects to the DXT-H4 via its network connection. Note: We recommend reading 4. Introduction to PCoIP first if you are not already familiar with the concept of PCoIP Connect to a DXT-H4 using SLP Discovery Important! This is one method you can use to quickly connect your zero client to a host. For a detailed description of all connection methods, see 5. Set up a PCoIP session. If the zero clients and KVM extender hosts are on the same subnet, you can use the Direct to Host + SLP session connection type to discover available PCoIP hosts on the subnet. You must know the IP address (or MAC address) of the KVM extender host that you want to connect to. 1. Select the Direct to Host + SLP Host Discovery session connection type from the drop down list. 3.6 STEP 6: Change the default password 1. For security, we recommend that you change the default password for your DXT-H4 at the earliest possibility. Important! You must enter a password before changing the configuration of host units and zero clients. The factory pre-set password for all Amulet Hotkey host units and zero clients is ahkdante. 3.7 How to power off the DXT-H4 To correctly shut down the unit, you must put the DXT-H4 into standby first before you remove power to the unit. See 7.11 How to power off the DXT-H4 for more information. 3.8 Further reading If you wish to read further about network considerations, refer to 6. Manage the network. For any configuration or deployment issues refer to 7. Additional information or contact Technical Support department (see contact details at the start of this manual). Figure 10: The zero client OSD discovers and lists the first 10 available PCoIP hosts discovered 2. Select the host you want and click OK. If the zero client successfully connects to the host, the front panel PCoIP status LED illuminates green to indicate an active session. 3. (Optional) You can also set the Enable Auto-Reconnect in the advanced settings to remember the last connected PCoIP host. Note: You must also configure a Direct from Client session connection type on the host. Page 17

19 Introduction to PCoIP 4 4. Introduction to PCoIP 4.1 What is PCoIP? The PCoIP (PC-over-IP) protocol compresses, encrypts and encodes the entire computing experience on a host PC. In a PCoIP system, a PCoIP host transmits the computing experience from a host PC (pixels only) across a standard IP network to a remote zero client. Actual data never leaves the host PC and all pixel transfers are encrypted with advanced security algorithms. PCoIP supports high resolution, full frame rate 3D graphics and HD media, multiple large displays, full USB peripheral connectivity, and high definition audio, all connected over the corporate LAN or WAN. PCoIP technology allows all desktops in your enterprise to be centrally located and managed in a data centre, while providing remote users with full desktop performance. This may be in a geographically remote location if necessary. There are three essential features of PCoIP: Host rendering; Multi-codec display processing; Dynamically adapts to network conditions Host rendering PCoIP renders display images on the host PC (or virtual machine). Host rendering preserves the PC environment so applications perform correctly. After an image is rendered on the host, PCoIP broadcasts just the encrypted pixels (not data) across the network to the remote client. (See 4.2 for more details). The remote clients are stateless, decode-only client devices called zero clients with all the benefits they bring, such as low maintenance, increased security, and cost savings. Note: This is an advantage over other remote protocols that use client rendering. To render an image on the client; each command from the host and response from the client must travel across the network. This degrades an application s performance while it waits for image rendering to complete. Figure 11: Typical PCoIP set up A DXT-H4 (1) connected to a closed host system (2) facilitates a remote desktop connection over a LAN/WAN (3) to a zero client (4) with quad video heads (5) Page 19

20 Introduction to PCoIP Multi-codec display processing A PC display includes different types of image elements (text, graphics, icons, video). Using the same codec to encode all these elements would use excessive network bandwidth. Instead, PCoIP continuously analyses and decomposes image elements, using the right codec for each pixel. PCoIP s intelligent image decomposition and encoding results in efficient transmission and decoding. This saves bandwidth while delivering the best user experience. In addition, PCoIP builds every pixel to a lossless state when they stop changing, ensuring a pixel-perfect image on the zero client regardless of network limitations Dynamically adapts to network conditions The PCoIP protocol lets you easily set image quality settings to manage bandwidth use and delivers the best possible performance for the network conditions. On congested networks, PCoIP adaptive encoders automatically adjust image quality within the limits you set. When the network is no longer congested, they automatically resume maximum image quality. 4.2 About PCoIP hosts Host function A PCoIP host is something that converts a remote PC (or blade workstation) into a pixel broadcast centre. The host s Tera-series processor uses advanced algorithms to encode a user s full desktop environment, allowing the host to deliver high-end images to a zero client in any location. In a PCoIP system, the PCoIP host is installed inside or near to the remote PC. The host takes digital video, audio and USB data generated by the PC and compresses and encrypts this data. It then transmits this data in real time over an IP network to the user s PCoIP zero client Host types The DXT-H4 is a PCoIP host that is external to the host PC or workstation. Other Amulet Hotkey PCoIP hosts are available in various form factors. Some install inside a PC while others are located near to a PC and connect to video, USB and audio ports using standard cables. Amulet Hotkey also supply a range of PCoIP blade workstations based on the class leading Tier 1 devices from Dell. These workstations include Amulet Hotkey BIOS and PCIe mezzanine cards to provide hardware GPU and PCoIP acceleration. See our website for more information. 4.3 About PCoIP zero clients PCoIP zero clients are secure, hardware-based endpoints that allow users to connect to a remote host PC or virtual desktop over a local or wide area IP network. They support multiple wide screen formats, HD audio, and local USB peripherals, providing a rich multimedia experience for users Functionality Zero clients can take many form factors, for example, as rackmounted cards. Amulet Hotkey DXZ4 zero clients are small, cased devices for your desktop. Users can interact with their desktops from any type of zero client and can even continue the same session if they move between zero client devices Data handling PCoIP zero clients use a highly integrated Tera-series processor to perform image decompression and decoding. At the desktop, they decrypt, decompress and distribute video, audio and USB data to the standard desktop peripherals, such as monitors, keyboard, mouse, and speakers or headset. A zero client also passes user generated USB and audio data back to a remote PCoIP host (see 4.2). To ensure desktop responsiveness, the process of image compression encryption-transmission by the PCoIP host and then decryption-decompression by the zero client happens very quickly, typically in just one frame (or less than 15 msecs). 4.4 Benefits of PCoIP zero clients Because zero clients just decode pixels to display images, they can be far simpler and more secure than a traditional desktop PC and other thin client solutions. They offer: Increased security; Low maintenance; Cost savings Increased security As PCoIP zero clients have a stateless architecture and no local data storage, they are the most secure endpoint available. Pixel transfers to the zero client are encrypted with advanced security algorithms. Zero clients are also immune to viruses and never need anti virus updates. Finally, zero clients comply with the most stringent government and security mandates. In particular, they support robust USB hardware security authorization, including user authentication and single sign-on (SSO) based on smart cards, proximity cards and other SSO devices. Page 20

21 Quad Display KVM Extender Host Low maintenance Zero clients are extremely easy to manage and do not require regular updates or patches. They have no application operating system, no general purpose CPU or RAM, no graphics processor. And they have no fan or hard disk to fail. Because they perform only pure image decompression, they are future proof. A zero client never needs a new operating system or updates for drivers, media codecs, or anti-virus signatures. Also, a zero client does not need to know about the applications being used (it just has to decode the pixels to display the image), so there are no version dependencies between the zero client and the host PC. There is no risk that future versions of an application will render the zero client obsolete PCoIP Management Console The PCoIP Management Console (see Figure 12) has a web interface that allows you to manage multiple devices (PCoIP zero clients and hosts) from a central console. From the console, you can view the status and connection information of all PCoIP devices. You can manage devices individually or by group. For example, you can create device groups based on location or department. In particular, you can assign configuration profiles to PCoIP devices and update device firmware (for the Teradici processor). You can also view device log files, reset devices, and control the power state of devices Cost savings Zero clients have significantly lower costs than traditional PCs and thin clients. They use less power, generate less heat, and often have a smaller footprint. Also, because they are simple devices, zero clients require minimal administration and have very low management costs. And because they are future proof, their extended life span is assured and they rarely need replacing. For more general information about PCoIP zero clients, visit PCoIP management tools You can interact with PCoIP hosts and zero clients through various management tools. See Table 7. Management tool PCoIP Management Console Administrative Web Interface (AWI) On Screen Display (OSD) Description Allows you to centrally administer a large numbers of PCoIP devices. You can organize zero clients into groups, define configuration profiles, and apply configuration profiles to groups. A web application that you can use to remotely configure individual zero clients and PCoIP hosts. A user interface on the zero client that allows you to configure and view information about the local client. Figure 12: PCoIP Management Console home page Note: The PCoIP Management Console plus supporting documentation is available for download. For more information on the PCoIP Management Console, contact Amulet Hotkey Technical Support.

22 Introduction to PCoIP Administrative Web Interface (AWI) The AWI is an embedded HTTPS web interface for PCoIP devices. It enables you to remotely configure individual PCoIP hosts and zero clients using a web browser. Example: You can set device power settings, connection speeds, and define initial setup parameters. The AWI also provides tools for updating the device firmware (for the Teradici processor). To access the AWI, browse to the IP address of the PCoIP host or zero client (see 1.8) On Screen Display (OSD) The OSD appears when the zero client is powered on and a PCoIP session is not in progress. The OSD Connect screen displays when you press the Menu button on the zero client front panel. Figure 13: Administrative Web Interface Figure 14: OSD Connect screen If the zero client is in a low power state (no activity for five minutes) the zero client automatically goes into a low power state by turning off the monitors. In this case, pressing the menu button or a USB mouse/keyboard will wake the client back up. The first video head detected will show the OSD. From the Connect screen, you can create a new PCoIP session between the zero client and a remote PCoIP host unit or a virtual desktop. The Options menu in the Connect screen gives access to various configuration pages (these pages provide a subset of the functionality provided by the AWI). You must enter a password to change any zero client settings; see 3.6. Page 22

23 Get connected 5 5. Set up a PCoIP session This section describes how to connect a zero client to a remote PCoIP host, such as a KVM extender host, or virtual desktop. 5.1 Power up the zero client After you install the zero client, you must then establish a PCoIP session between the zero client and a remote PCoIP host or virtual desktop. When you press the power switch on the zero client for the first time, it displays the On Screen Display (OSD) connection screen. If more monitors are connected, the menu displays on Video port 1. The connection screen will also display if the Menu button is pressed while the unit is on. 5.2 Types of PCoIP session To set the type of PCoIP session the zero client will use to connect the host, use the OSD and change the configuration settings. 1. Select Options > Configuration and select the Session tab. 2. Click Unlock and enter the password. (Default is ahkdante) The following connection methods are available: Auto Detect Connect directly to a specified host Connect to a choice of hosts using SLP Discovery PCoIP Connection Manager PCoIP Connection Manager + Auto-Logon Connect using VMware View Connect using a connection broker Note: For full details about each connection method, refer to the Session Connection Types section of the Teradici PCoIP Zero Client and Host Administrator Guide Auto Detect With this setting, the zero client connects to the address of any specified server. This session type is used where the client must choose between virtual and physical hosts Connect directly to a specified host Important! This connection method is not practical for very large PCoIP deployments. 1. Select the Direct to Host session connection type from the drop down list. Figure 15: Session selection drop down list Figure 16: Direct to Host connection type 2. Enter the IP address (or DNS name) for the PCoIP host. Note: You must also configure a Direct from Client session connection type on the host. Page 23

24 Get connected 3. (Optional) You can also set the Enable Auto-Reconnect in the advanced settings to remember the last connected PCoIP host Connect to a choice of hosts using SLP Discovery If the zero clients and PCoIP hosts reside on the same subnet, you can use the Direct to Host + SLP session connection type to discover available PCoIP hosts on the subnet. You must know the IP address (or MAC address) of the PCoIP host that you want to connect to. Important! Use this connection method mainly for testing and evaluation purposes. 1. Select the Direct to Host + SLP Host Discovery session connection type from the drop down list Connect using VMware View You can configure zero clients to use PCoIP to connect to a virtual desktop in a VMware View environment. If you want users to log on manually: 1. Set the session connection type to View Connection Server. Figure 18: View Connection Server selection 2. Enter the IP address (or DNS name) of the VMware View Connection Server. Figure 17: The zero client OSD discovers and lists the first 10 available PCoIP hosts discovered 2. Select the host you want and click OK. If the zero client successfully connects to the host, the front panel PCoIP status LED illuminates green to indicate an active session. 3. (Optional) You can also set the Enable Auto-Reconnect in the advanced settings to remember the last connected PCoIP host. Note: You must also configure a Direct from Client session connection type on the host PCoIP Connection Manager Using a PCoIP Connection Manager allows you to centrally administer a large number of PCoIP devices. 1. Select the PCoIP Connection Manager session connection type from the drop down list. 2. Enter the server URI of the PCoIP Connection Manager PCoIP Connection Manager + Auto-Logon This connection type allows you to include the user name, password and domain of the user so that the connection and logon of the zero client is automatic. 1. Select the PCoIP Connection Manager + Auto-Logon session connection type from the drop down list. 2. Enter the server URI of the PCoIP Connection Manager. 3. Enter the user s Username, Password and Domain Connect with View Connection Server and Auto-Logon 1. Set the session connection type to View Connection Server + Auto-Logon. 2. Enter the IP address (or DNS name) of the VMware View Connection Server. 3. Enter the user s logon credentials. Other virtual desktop connection types are also supported, such as kiosk implementations. For details, see the Teradici PCoIP Zero Client and Host Administrator Guide Connect using a connection broker A connection broker is a resource management application. The broker dynamically assigns zero clients to host PCs from the identity of the user connecting from the zero client. 1. Set the session connection type on both the zero client and PCoIP host to Connection Management Interface. Figure 19: Connection Management Interface selection Page 24

25 Quad Display KVM Extender Host 2. Enter the IP address (or DNS name) for the third party connection broker. 3. Click OK. See section 6.2 for more information about third party connection brokers. 5.3 Set an automatic connection You can set up zero clients to automatically connect to a remote PCoIP host or virtual desktop when the end-user logs on. With this setup, there is minimal impact on the end-user. Once set up, at the end of the day the user: 1. Logs out of Windows. 2. Powers off their monitors. 3. Presses the power switch on the zero client to put it in standby. In the morning, the user: 1. Presses the power switch on the zero client to bring it out of standby. 2. Turns on their monitors. There is a pause while the zero client acquires the host IP address. The PCoIP On Screen Display (OSD) briefly shows a connection progress screen on the monitor attached to video output 1. See Figure Disconnect from a host PC or virtual desktop 1. Press the front panel Menu button. 2. Choose Disconnect from the Zero Client Control Panel that appears on screen. See Figure 21. Figure 21: Disconnect option on the OSD 5.5 Further information For further information about zero client security, see the Teradici PCoIP Zero Client and Host Admin Guide, particularly the PCoIP Zero Client Security Overview and Security settings Checklist sections.

27 Network management 6 6. Manage the network 6.1 Consider network bandwidth requirements PCoIP uses the Internet Protocol (IP) to transmit data between the host and client. The data can be routed over any IP compatible infrastructure between offices or across continents. In every case, performance depends on the available bandwidth and signal latency Factors affecting bandwidth The bandwidth required depends on several factors, including: the number of pixels changing from frame to frame; the number and resolution of screens to be encoded; settings made by the user. Exact bandwidth requirements for PCoIP are difficult to predict, use the values in Table 8 as a guide only: Setting Idle display ~ 0 No USB or audio data General office use (that is, writing documents) Audio A significant display change (such as minimising or restoring a window) USB transfers Playing full-screen video Bandwidth ~32Kbit/s per pair of monitors Kbit/s. 2 Mbit/s. 4-5Mbit/s < 6Mbit/s of traffic < 70Mbit/s Example2: A quad video head system running real time full screen video might peak at 70 Mbit/s What happens when available bandwidth is exceeded In all cases, PCoIP builds to a lossless image. If the required bandwidth is not available, PCoIP dynamically adjusts the quality to match. You can also use the zero client management tools (see 4.5 PCoIP management tools) to optimise performance for most conditions. If bandwidth usage is a concern, we recommend testing and monitoring on your network. For assistance, please contact Amulet Hotkey Technical Support. 6.2 Choose a connection broker if required All Amulet Hotkey zero clients can be configured to use a third party connection broker (also known as a connection management server). For example, the following connection broker products include PCoIP support: VMware View Connection Server; Leostream Connection Broker. Important! The DXT-H4 and DXR-H4 are currently configured to only work with VMWare Horizon brokering Role of the connection broker Connection brokers simplify the administration effort for managing large complex PCoIP systems. A connection broker interacts with systems such as Active Directory to dynamically assign PCoIP hosts to zero clients based on the identity of the user establishing a connection from the zero client. Connection brokers are also used to allocate a pool of hosts to a group of zero clients. Table 8: PCoIP bandwidth requirements Example1: A dual head configuration running a word processor, spreadsheets, and 2D illustrations/designs will typically use between 1 and 10 Mbit/s. Page 27

28 Network management Specify the connection broker You can use any of the available management tools (see section 4.5 PCoIP management tools) to specify the connection broker: you must provide the IP address or DNS name of the connection broker; you must also specify the Connection Management Interface connection type for the PCoIP session Using the connection broker Instructions for using a connection broker to connect your zero clients to hosts are available in the Teradici PCoIP Zero Client and Host Administrator Guide (available to download from techsupport.teradici.com). Note: For further information about using connection brokers, contact Amulet Hotkey Technical Support. See also the Knowledge Base Article Can I use a connection broker with PCoIP technology?
