Virtualization Implementation Steps

Step one: Determine the scope of virtualization?
According to the company's business and technical requirements, define the group, branch companies to implement the virtualized environment, or the local servers are centralized to a single location server. and define the objectives and implementation schedule of virtualization and the relevant principals? Tools and methods:?
You need to discuss with departments to identify the problems and needs of each business unit or company's it production environment to determine the virtualized environment. and use Word or project records.

Step Two: Create a list of applications and services
?
Establish application and service compatibility, availability requirements such as processor architecture, number of processors, memory requirements, storage requirements, and other special hardware to identify applications and services that require high availability. Tools and methods:?
Understand the applications and services that are running in each business unit or company it production environment, such as SQL or IIS, such as AD or DHCP, to determine if virtualization is required and whether high availability is required, and to establish inventories. Preliminary confirmation of the existing hardware such as the number of CPUs, such as the establishment of a record, in case later can be reused.

Step three: Identify resource requirements

Collect and analyze relevant statistical data, including performance history, specifications and requirements, load test, etc. tools and methods:?
1, through the performance counter way to determine the CPU for a period of time and so on usage.
2, through the Map tool to evaluate the hardware functions, to generate a proposal for evaluation and planning. This method can be used for this step and step seven.
3. Can you pass pal? Tool to analyze performance records for Windows systems.

Step four: Select a backup method
Determine whether the backed up objects are for individual application backups, virtual machine backups, or physical hosts. What about storage? What is the order of application backup??
Backup determines the degree of performance, downtime, storage space, ease of recovery, and operational complexity, as well as the program and backup interval for data loss. Tools and methods:?
1. Through Windows? Server? BackUp?
2, some third-party backup professional tools such as SYMANTEC\EMC and so on.? 3. Hyper-V management Console (such as export, Snapshot?). ）?

Step Five: Choose a method of high availability?

Depending on the characteristics of your application, you can use the system's built-in NLB or failover cluster: for example, Web sites, Terminal Services are more appropriate for NLB, and databases are suitable for failover clustering. Based on the schema design, determine whether the NLB or failover cluster is in the same physical host or a different physical host. Tools and methods:?
1. How to create high availability for the same host or different hosts?
2. What is the significance of creating high availability for the same host? (Real high availability?) )? 3. High availability of network and storage? (combined with disaster preparedness)

Step Six: Summarize the application requirements
Determine the hardware requirements for the virtual machine, and then decide which virtual machine the application is installed on, and whether different application applications can execute in the same virtual machine? How to back up, whether high availability is required. Tools and methods:?
1, combined with the physical host hardware resources and network architecture to analyze the different application performance requirements. 2. Are the associated applications on the same virtual machine or on the same host? Discuss application placement such as the Moss class.
3, P2V to carry out the existing system and application of the migration??

Step Seven: Select the configuration of the physical host

Based on the full utilization of existing hardware devices, consider the cost, performance, availability, stability, and manageability to determine whether a new hardware device needs to be procured. Tools and methods:?
1, the combination of steps Sunline, using such as map tools to conduct evaluation, etc.?
2. It is also possible to consider resource pools and application placement of virtual machines, as well as virtual machine placement of hosts. 3. The hardware meets the conditions of virtualization assistance (detection tools such as: SecurAble)?

Step eight: Determine the location of the physical host?

Consider cost, manageability, security, performance, and availability to determine if a host is placed in an IDC room, a self-built room, or a lease. Tools and methods:?
1, IDC room selection need to reference a few points.
Power, constant temperature and humidity, BGP, cabinet, response service, and development?
2, self-built computer room to pay attention to matters.? Step nine: corresponding virtual machine to physical host?
It is placed on the corresponding physical host based on the operating system running in the virtual machine and the workload of the application.
Need to understand the resource utilization target and hardware capacity of the physical host. Avoid placing virtual machines that are consuming system resources on the same physical host.
Tools and methods:?
1, scvmm?2008? Smart placement of R2.?
2, and step six to understand dynamic resource adjustment, etc. 3. What is the relevance of the operating system or application??

Step Ten: Determine the physical host backup method?
Confirm that the object being backed up is for an operating system or application in a single virtual machine, or for a physical host to back up the entire virtual machine?? Tools and Methods:?
1, Windows?server?backup?
2. Hyper-V Self-feature (can the snapshot be used as a backup)? 3, third-party professional backup tools and storage devices. CDP, data deduplication, etc.?
The backup mechanism of some vendors is illustrated with the storage architecture.

? Step 11: Design for high availability?

On the basis of step five, determine whether the virtual machine is in an NLB or failover cluster, or a failover cluster is established between the Hyper-V hosts. Or between hosts and virtual machines. Tools and methods:?
1. Introduction to the Hyper-V host failover cluster? 2, Live? Migration working mechanism?
3. Network redundancy (multiple NIC, fibre switch or HBA card)
Step 12: Design the storage infrastructure?

Is it a direct-attached storage (DAS) or a NAS, or a SAN, etc.? is the virtual machine using a dynamic disk or a fixed size disk space?? virtual machine direct access to physical host hard disk??
Storage space and its own backup mechanism selection (RAID5, etc.). Tools and methods:?
1, DAS, NAS, San Introduction.
2, FC? San and iSCSI? SAN, and windows?ss?2008.3, a typical vendor-provided scenario profile (such as NetApp).

? Step 13: Design your network infrastructure?

Hyper-V provides three types of virtual machine selection, as well as VLAN capabilities. DMZ, Intranet, Internet?? tools and Methods:?
1. Introduction to Hyper-V three types of virtual machine network type. 2, NLB, and network Considerations for failover Cluster design. Step 14: Confirm that all methods are feasible?
Verify that the above steps determine compliance with the enterprise requirements, confirm the application requirements, and the physical host infrastructure design.
Tools and methods:? 1, discussion and verification.?
2, document records, topology design, etc. 3, responsibility, personnel, time, etc.

? Step 13: Confirm that all methods are feasible
