HP Image Manager Concepts & Technical overview

Managing computers’ software : 

Managing computers’ software All what is not hardware is software (OS (and hotfixes, patches…) is software) Software is stored on local disk drives. User data are stored on servers. Managing N computers = managing N disk drives Managing N computers that share the same software applications is redundant and repetitive Managing a fleet of computers involves a lot of software management

Managing a fleet of networked computers : 

Managing a fleet of networked computers All desktop device are networked and can boot off the network (with PXE) Every network has some servers Networked and share storage is very common for data but not for software nor OS Nowadays, computers are connected to a network

Reduced Management Complexity with an OS Streaming Solution by HP : 

Managing multiple PC’s is challenging and time consuming. With an easy to deploy OS streaming solution only one image has to be managed per environment Un-paralleled user experience thanks to local processing and full benefit of RCS Transparent to users, thin clients experience becomes the same as regular PCs Users spend less time (or even no time) managing PC’s and more time working Radically simple to implement and use Protect users from malicious behavior like never before Reduced Management Complexity with an OS Streaming Solution by HP

Image streaming solution HP Image Manager : 

The Stateless client boots to the network via PXE protocol. DHCP evaluates the request from client, and relays necessary TCP-IP information. NVDD provides a Virtual Disk On Demand to the Stateless client. This Virtual Disk comprises an OS and some applications that the client load On Demand. The local OS acts as if there was a local disk drive Now customers can have their cake and eat it too. Enjoy the personal flexibility of a PC while maintaining the security and manageability of a Stateless Client. All data remains unique and secure on the server. NVDD serves Virtual Disk Drive(s) Runs on Windows, Linux and FreeBSD The Stateless Client boots from the Network PXE = Pre-boot eXecution Environment DHCP = Dynamic Host Configuration Protocol TCP-IP = Internet Protocol Suite NVD = Network Virtual Disk (Protocol) NVDD = Network Virtual Disk Daemon Gain the power of a PC on your Stateless Client with the added security, manageability and reliability you need by streaming an image to Stateless Stateless Clients Image streaming solution HP Image Manager Local OS: Windows 2000 and XP. Linux is working in lab. Vista support currently being developed

Client VirtualizationOS Streaming to Desktop : 

Client VirtualizationOS Streaming to Desktop HP Image Manager delivers desktop images (OS and Application Stack) on demand to HP Thin Streaming Appliance Clients. Images can be standardized or individualized; allowing for maximum flexibility in Client Virtualization Adoption Desktop Images are configured, deployed and managed centrally, allowing customers to increase security and flexibility while at the same time significantly reducing management complexity and providing a mechanism for groundbreaking business continuity and disaster recovery. Customers Achieve all of these Values, along with the benefit of an uncompromised and familiar user experience. I.E. Full USB and Device Compatibility Full Multimedia Capability

Limitations : 

Limitations Brings the best of powerful desktop computing and central management. Suitable whenever several desktops are supposed to have the same set of applications Perfect solution for education: no limitation caused by “remote desktop” protocols and yet a centralized and secured environment. Perfect solutions for call centers: Desktop are secured, powerful and can be repurposed in minutes by assigning a new image to them Greatly simplify VDI for it solves two of the major issues of VDI: Storage mutualization and software management deployment. Key points Requires a wired LAN No PXE is available for WiFI Requires at least 100mb/s network, which is rarely available on WAN

HP Image Manager : 

HP Image Manager Setting up Create a Virtual Disk Update a Virtual Disk Share the updated Virtual Disk

Setting up - Préparation : 

Setting up - Préparation 1- Prepare a “master” client “Typical” installation of OS and applications

Setting up – Install the server : 

Setting up – Install the server 2- Install and launch Image Manager Server The server module (nvdd) shares a small virtual disk (provided)

Setting up – Create a Virtual Disk : 

Setting up – Create a Virtual Disk 3- Run ClientBuilder from the client The client then detects the virtual disk that the server shares; it installs the components (drivers) in the OS configuration. The OS on the client is then able to use the virtual disks shared by an Image Manager server. The virtual disk is created on the server and contains what was on the client’s local disk drive (an OS potentially some applications) When the virtual disk is created, ClientBuilder restores the previous configuration of the client (removes drivers and application, restore previous settings…) smalldisk E:

Setting up – Start the clients : 

Virtual Disk 1 C: C: C: C: C: Setting up – Start the clients 4- Use the clients Remove the physical HDDs (if any) from the clients Share the virtual disk that was previously created Boot the clients off the Virtual disk

Setting up – Modify the virtual disk : 

Virtual Disk 2 Setting up – Modify the virtual disk 5- a/ Update the image in “admin” mode Boot up one client in admin mode off a copy of the virtual disk to modify Modify the virtual disk from the client the usual way: Every change is recorded in the image Virtual Disk 1 C:

Setting up – Deploying the virtual disk : 

Setting up – Deploying the virtual disk 5- b/ Share the updated Virtual Disk Configure the server for it to serve the modified virtual disk Reboot the clients Virtual Disk 2 The clients all boot up off the updated disk image Deployment has become useless!

HP Image Manager : 

HP Image Manager A little deeper Needed features (high level) Competitive Writes Write modes (mounting modes) Preventing Name Collisions

Virtual Disk Streaming: Needed features : 

Virtual Disk Streaming: Needed features Virtual Disk Streaming is basically two features Boot off Remote storage (aka Remote Boot) Create a disk that a remote client will be able to mount as a regular disk drive Boot the desired client OSes off such disk Share a common logical disk among several clients at the same time Prevent competition when two clients want to write to the same disk at the same time Customize each client “personal” disk so that a specific client “sees” a disk that is slightly different from the one its neighbor sees. Especially, IP address, host name, domain credentials Support heterogeneous hardware in the same image

Sharing a virtual disk: Competitive Writes : 

Sharing a virtual disk: Competitive Writes In order to be able to share the same virtual drive between several clients at the same time, it is necessary that clients do not write in the virtual drive image itself. The sectors that clients request to write in the disk drive are actually written in a client specific space named CVOL (Client/Volume OverLay) What is a CVOL ? A CVOL is a Server Based Write-Cache (that contain a data file). Each CVol contains the sectors of a Virtual HD that have been written by a certain client. Each client has its own CVOL for its virtual HDs (if a client mounts several Virtual HD, it has one CVOL per mounted drive). CVOL are “deltas” to Virtual HD file.

CVOL usage : 

Writing request CVOL usage

CVOL usage : 

Reading request CVOL usage Is sector N in CVol? Yes

CVOL: Write modes : 

CVOL: Write modes There are several ways of handling CVol files at boot time Protected Mode (Volatile Mode) The CVOL files are erased when the client reboots (similar to Write Filter) Clients boot in an always clean and known state Keep a powerful desktop! Normal Mode The CVOL files are kept when the client reboots Use your diskless computer or flashless thin client as a FAT PC Keep an easy-to-manage and centralized behavior Usually not recommended for end-users (the existing CVols need to be deleted or rebuilt when the image change). Used by admins. Residual Mode The CVOL files are restored (from “reference” CVOL files for the client) when the client reboots Use protected mode but keep a per-computer tuning Enable product activations and license management Usually not recommended (the reference CVols need to be rebuilt when the image change)

Preventing Name Collision : 

Preventing Name Collision In order for several clients to share the same image and to be present on the same LAN, each client must have its own computer name (NetBIOS name for Windows). Image Manager uses a dedicated driver (BDRUPD) to customize each client name BEFORE it is read by Windows OS. The actual name is read from the virtual disk server configuration (usually linked to the client MAC address) or can even be set by DHCP (DHCP option 13) A similar technique is used to load customized Domain Credentials on a per-client basis, so that each client has a unique Domain SID, domain machine account etc. Example of name customization when the clients are VMs in an ESX server
