Part 1 PY RI GH TE D RI TE MA Chapter 1: Proposing Virtualization Chapter 2: The Architecture of Hyper-V CO u u AL Overview
Chapter 1 Proposing Virtualization The first phase of any project, whether you’re an internal consultant or an external consultant, is to develop a proposal for that project so that you can gain executive commitment. The best way to secure acceptance is to cater to both the technical requirements and the often overlooked business case requirements. The technical solution should be a business-focused solution and be understandable by both technical and nontechnical staff.
| CHAPTER 1 PROPOSING VIRTUALIZATION In its most simplistic form, this involves the implementation of replicated storage to support the constituent parts of the virtual machine. Storage vendors for the most part provide either in-box or add-on replication capabilities, which are easily enabled. Replicating the storage presented to the virtualized infrastructure, even without storage array–based replication techniques leveraging software vendors, provides the basis for a business continuity service.
THE BUSINESS CASE u Consistent level of service u Reduced operational costs u Standardized management approach Lower Costs Virtualization helps drive down both CAPEX and OPEX costs. CAPEX cost savings can come in the form of reduced expenses for the acquisition of hardware and the potential savings for datacenter real estate. OPEX costs stem from the reduction in power and cooling costs, management costs, and the costs associated with server downtime or outage costs.
| CHAPTER 1 PROPOSING VIRTUALIZATION In addition, SCVMM supports various different options for provisioning virtual machines. By leveraging its built-in PowerShell script library, you can automate the entire provisioning process. Green Computing Energy consumption is a critical issue for IT organizations today, whether the goal is to reduce your costs, save the planet, or keep your datacenter running.
THE BUSINESS CASE Active Directory users or groups can be added to self-service user roles. The permissions granted to the user role apply to all members of the user group whether they are individuals or groups. Virtual machine owners can be individual users or groups. Under individual ownership, an individual owns, operates, and manages its own virtual machines. Under group ownership, virtual machines are owned, operated, and managed by the group.
| CHAPTER 1 PROPOSING VIRTUALIZATION locations supports the business driver for functionality in the event of a disaster.
THE TECHNICAL CASE Standardization Hardware and operating system standardization has been considered a best practice for many years. IT administrators running datacenters with standardized server hardware and operating system images typically have fewer headaches than those working in mixed environments. This best practice evolved in the physical world and is more significant now when it comes to virtualization and Cloud-based computing.
| CHAPTER 1 PROPOSING VIRTUALIZATION Virtualization allows you to manage your production environment more flexibly, from anywhere, at lower costs and with a reduced level of risk. By leveraging virtualization, you can provide small-scale environments that are cost effective and that scale up very easily. Hyper-V R2 increases this level of flexibility by introducing a new processor compatibility feature.
