2. HP Restricted Objectives Describe virtualization with VMware Explain virtualization with Citrix XenServer Describe virtualization with Microsoft products 1 – 2

3. HP Restricted3 Describe virtualization with VMware

4. HP Restricted How does virtualization work?

5. HP Restricted Host operating system-based virtualization A host-based virtualization system requires an operating system (such as Windows or Linux) to be installed on the computer

6. HP Restricted Virtualization using a bare-metal hypervisor A bare-metal hypervisor system does not require an operating system. The hypervisor the operating system

7. HP Restricted What is a virtual machine? From the user’s perspective, it is a software platform that, like a physical computer, runs an operating system and applications A virtual machine is a discrete set of files: – Configuration file – Virtual disk file – NVRAM settings file – Log file

8. HP Restricted VMware ESXi: Virtualization platform ESXi is bare-metal, efficient, and reliable hypervisors running directly on server ESXi abstract CPU, memory, storage, and networking into multiple virtual machines

9. HP Restricted What’s New in vSphere 5.0? vSphere 5.0 is the first release to offer only the ESXi hypervisor architecture. vSphere 5.0 does not include ESX. – The service console no longer exists. – VMware vSphere Command-Line Interface and VMware vSphere PowerCLI are available for command-line administration. vCenter Server 5.0 can still manage ESX hosts (3.5 and 4.x). The upgrade process upgrades ESX/ESXi 4.x to ESXi 5.0.

10. HP Restricted VMware ESXi features Uses standard and distributed virtual switches, NIC teaming, and VLANs Uses the VMware vStorage VMFS for storing virtual machines Managed by VMware vCenter Server Takes advantage of various VMware vSphere features, such as VMware Vmotion Can be accessed using the VMware vSphere Client

11. HP Restricted ESXi Installable, and ESXi Embedded ESXi Managed with a BIOS-like direct console or vCLI A high-security, 32MB footprint ESXi Installable – Available as an installable CD-ROM boot image ESXi Embedded – ESX image preinstalled as firmware or burned onto an external USB key or SD card by the hardware vendor

12. HP Restricted ESXi architecture

13. HP Restricted Configuring ESXi The direct console user interface is similar to the BIOS of a computer with a keyboard-only user interface

14. HP Restricted Using the vSphere Client The vSphere Client is an interface used to connect remotely to ESX/ESXi or vCenter Server from any Windows PC Download software from the main page of ESX/ESXi Point to ESX/ESXi host Download vSphere Client to supported Windows system

15. HP Restricted Logging in to ESXi At the vSphere Client login screen, enter: – Host name or IP address of ESX/ESXi host – User name root – Password for user root vSphere Client can be used also to access vCenter Server

16. HP Restricted vSphere Client view

17. HP Restricted ESXi licensing Before purchasing and activating licenses, you can install ESXi in evaluation mode – Intended for demonstration and evaluation purposes – Allows software to be completely operational immediately after installation – Does not require any licensing configuration – Provides full functionality of ESXi for 60 days from the time you install it – Allows the software to notify you of the time remaining in the evaluation period

18. HP Restricted18 Explain virtualization with Citrix XenServer

19. HP Restricted Xen and XenServer The three key components to the Xen and XenServer relationship are: – Xen open source project – Xen hypervisor – XenServer products

20. HP Restricted Identifying the XenServer product line Citrix XenServer is available in four editions, as well as OEM editions: – Express Edition – Standard Edition – Enterprise Edition – Platinum Edition – OEM Editions

21. HP Restricted XenServer 5 product line FeatureExpress EditionStandard EditionEnterprise Edition Platinum Edition Native 64-bit Xen hypervisor Windows and Linux guests XenAPI XenCenter XenConvert Multi-server management Subscription Advantage 1 st year VLAN configuration XenMotion live migration Shared IP-based storage Resource pools Resource QoS controls Server Provisioning

22. HP Restricted XenCenter overview XenCenter manages: – XenServer hosts – Virtual machines – Physical and virtual resources Multiple XenCenters can be used to manage a single pool. The event mechanism keeps each client updated.

23. HP Restricted XenCenter

24. HP Restricted XenCenter performance data XenCenter displays real-time status and trending of: – CPU usage – Memory usage – Disk and network I/O Performance data: – Starts tracking when XenCenter opens and connects to one or more servers – Available for the last 10 minutes to the last year – Is persistent

25. HP Restricted XenServer architecture overview Xen provides a next generation x86 virtualization platform using a combination of two technologies: – Paravirtualization – Hardware virtualization

26. HP Restricted XenServer hardware requirements ComponentRequirements CPU 64-bit x86 CPUs. Intel VT or AMD-V processors are required to run Windows VMs Physical memory One GB of RAM minimum but two GB of RAM recommended Network 100 Mbps minimum but 1 Gbps recommended. Storage 16 GB to install; 4 GB is for the control domain, 4GB is reserved for in-place upgrades and 8 GB is reserved for VM storage. Both local disks and remote storage are supported

27. HP Restricted27 Describe virtualization with Microsoft products

28. HP Restricted Windows Server 2008 R2 Hyper-V Next-generation hypervisor Integral feature of Windows Server 2008 R2 New features: – Live Migration – Hyper-V Management Console and PowerShell cmdlets – Up to 64 processors per host – TCP Offload and Jumbo Frames

29. HP Restricted HP support for Hyper-V Broad support for Microsoft virtualization technologies Industry standard servers – HP ProLiant servers – HP BladeSystem – Most G6 and G7 servers are supported and certified – Including SL and ML/DL100 series StorageWorks storage
