Virtualization

VMware :

Although VMware dominates the server virtualization market, IT professionals increasingly consider Microsoft as an alternative. VMware has yet to see a market share impact, and has been able to maintain its pricing models, even in the face of a free Hyper-V. VMware continues to raise the innovation bar while broadening its management reach via software-defined networking with NSX and software-defined storage with Virtual SAN. Taken together, VMware’s software-defined data center (SDDC) strategy is intended to make data centers fully virtualized and programmable. VMware has built a strong offering in cloud management platforms (CMPs). Its CMP, VMware vCloud Automation Center (vCAC) 6.1, is the result of its DynamicOps acquisition and its Fabric Manager solution, and is part of the larger vCloud Suite (vCS). This offering enables IT organizations to provide private cloud for *application as a service (*aaS).

VMware’s offerings for infrastructure management are bundled in its vCenter Ops offering. This includes virtual infrastructure discovery, performance and availability, analytics and configuration management. While not as comprehensive as traditional infrastructure management solutions (it lacks application performance management [APM] and robust capacity), it is focused on the “better together” approach to managing a VMware stack. VMware Horizon Suite is a collection of tools to meet the end-user computing needs of enterprise clients. The foundation of Horizon is View, one of the two dominant hosted virtual desktop products, which has been well-received because of its ease of use. Horizon also includes Workspace, a set of tools that allow anywhere access to applications, desktops and data through a unified platform. VMware’s Type 2 client hypervisor products (such as Fusion and Workstation) and ThinApp application virtualization round out VMware’s core end-user computing offerings. VMware also acquired Desktone, a cloud-based management toolset targeted at service providers for the desktop-as-a-service market.

Hyper-V Infrastructure :

Requirements • Architecture • Management Options • Performance Factors • Deployment Planning • Hyper-V in Production
Introducing Hyper-V • Hypervisor-based virtualization • Only available in 64-bit installations • Improvements over Virtual Server include – Improved performance – Better support for SANs – Running on Server Core installations – Improved virtual machine managementHardware Requirements • Must be run on a 64-bit system • Hardware-based virtualization enhancements are required – Intel VT – AMD Virtualization • 2 GHz or faster processor • 1 GB minimum RAM
Hyper-V Server 2008 • Two implementations exist – Hyper-V Server 2008 • Free • Supports up to 4 processors and 32 GB RAM – Hyper-V running on Windows Server 2008 • Free after you purchase Windows Server 2008 • Supports up to 24 logical processors and 2 TB RAM with Enterprise or Datacenter editions

Hyper-V Architecture Parent Virtual Virtual Virtual Partition Machine Machine Machine Hypervisor Hardware
Installation Options • Server Core – Slimmed version of Windows Server 2008 – Reduced attack surface – Increased performance • Full Windows Server 2008 install – Hyper-V may run alongside other services – Full GUI management on the local server • Hyper-V Server 2008 – Basically Server Core without additional services
Installation Procedures • Pre-Installation – Name the server appropriately – Set the Administrator password and join a domain, if necessary – Assign proper static IP addresses • With the GUI 1. In Server Manager, use the Add Roles wizard • With Server Core – Type ocsetup Microsoft-Hyper-V at the command line and press ENTER – Click “Yes” to restart after installation (that’s right the “non-GUI” Server Core often uses the GUI to notify you of things ?)
Management Options • Direct management – Command line – Hyper-V management console • System Center Virtual Machine Manager (SCVMM) – SCVMM Workgroup Edition supports five physical hosts – VMware VirtualCenter is required to manage VMware assets
VM Performance Factors • Memory • Storage • CPU • Network
Planning Hyper-V Deployments • Four key questions must be answered – How will virtual machine hosts and guests be managed? – What is your budget? – What guest operating systems must be supported and how many? – What services must run on the guest installs? • With these questions answered, you can estimate hardware and software resources
Calculating the Cost
Virtualization Assessment • Locate devices and applications that can be virtualized • Calculate cost savings • Discover security problems • Generate Excel and Word reports • Links to important documentation at Microsoft.com
