How to use server virtualization to optimize data centers

Server virtualization was successful because it implemented the same application software and operating system on the virtual machine as the physical server. Virtual I/O is the same principle.





I/O virtualization, you still have devices similar to the storage and network adapters (NICs and HBAs) you currently have, but they become software devices rather than hardware. You still have multiple physical ports to connect to separate LANs and Sans, but now adapters (NICs and HBAs) can be assigned to those software ports instead of physical ports.





Cost Total plus





you first need to calculate your I/O cost, you may find the neglected cost savings space. Take into account the costs of servers, switches, network adapters, and cables. Don't forget energy, rack space, and the time it takes to manage your infrastructure. You must understand the seriousness of the problem before you understand the cost savings space.





Estimating Flexibility





do your business needs change periodically? Do you consider implementing management services or cloud computing models for enterprise IT system operations? If so, increased flexibility will have a huge payoff. When you assign new connections to the server, you'll probably get a bigger payoff from these devices. When estimating the interconnection requirements of the equipment, the unintended cost is taken into account. Assume that any server must acquire any resources at one point in time. You can react faster to unintended changes and better cater to your needs.





Find Bottlenecks





is your server I/O restricted? This will result in reduced utilization of equipment and unnecessary cost expenditures. If you have a monitoring tool, such as a ESX device, see how much I/o utilization is. You may find that I/O is a limiting factor and you could have deepened the integration.





Simplified





because the cost of I/O is nearly as close to the cost of the server itself as it is, it needs to be simplified in the next configuration. A simplified I/o infrastructure will cost less to purchase and install, and will reduce the risk of downtime caused by human error.





Search for cost-saving methods





One cost savings may lead to another cost savings possibility. Simplified I/O infrastructure makes servers smaller and less expensive. This enables each server to save thousands of dollars.





through innovative means





the same way in the future means your cost structure will not change. Look for high cost areas that can be improved through innovation. Innovative technologies, such as server virtualization, iSCSI storage, and I/O virtualization, offer more cost savings than forced savings. The core of virtualization is to do more with minimal cost.





launch trial run





the investment returns of new technologies take time, and cost savings are quick. To speed up this process, consider developing new cost savings in the enterprise part of the IT environment. This way you can optimize this approach before it is done on a large scale. And you have daily data to prove that this approach is useful, and you will have the experience of ensuring success.





virtualization deployment requires a system architecture. Virtualization solutions now cover everything from servers, desktop systems to presentation systems. The day-to-day operation of the management of the process is particularly important. Because this is a dynamic process, not a static process, especially the virtualization Management suite, the dynamic migration of virtual machines, the deployment of dynamic resources in the process of server application, dynamic resource monitoring, dynamic resource configuration, will play a large role.
