A smooth transition solution for data center to virtualization

In a typical datacenter, it's very common to provide more servers and storage devices than really small requirements. This is done to address the potential peak load periods in the future, meeting high availability, and disaster recovery requirements. This leads to a huge waste of expensive resources. In fact, server usage is usually less than 25%, which is why http://www.aliyun.com/zixun/aggregation/13995.html "> Server virtualization has been developing extremely fast over the past few years.

So what can you do in addition to virtualizing a single server and its applications? What if you were able to control all the servers in the datacenter-physical or virtual-and center them on the basis of specific business or technical needs? If this question brings up your interest, , you can learn about some scalent systems companies and its virtualized operating environment (V/OE).

Scalentv/oe is a software solution that allows enterprise data centers to dynamically change workloads, change network and storage topologies, and make these running servers accessible without any changes to physical machines, cabling, LANs, or sans.

But Scalentv/oe is not an operating system like VMware. Instead, V/oe is a control system that provides real-time management and automation capabilities throughout the physical and virtual servers. The Scalent controller (server) software runs on one machine, not in your data center. Scalentv/oe can access every physical or virtual machine, interact with lights-out management protocols, and let them boot or power off. Then, when a machine is started, scalent establishes the correct network and storage address in real time.

For example, if a machine becomes a mail server, scalent will connect it to the mail network and storage. If the machine is designated as a ESX server (at a particular moment), Scalent will connect it to the correct ESX cluster network and storage. Scalent then lets the machine boot from the network, running a bare-metal software image that can be found on the central store connected to the machine. Typically, a bare metal software image can be Windows (an Exchange server, SQL Server, or other), Linux (Apache, SAP, Oracle, or other), Xen, or ESX (a series of software on a virtual machine).

What makes data center operators particularly interesting is the portability of images and the separation of scalent and data paths. For the portability of the image, Scalent can put the server image on the physical machine or virtual machine to start, without the need for processing, are real-time operations. Your Microsoft Exchange mail server may be launched on a VMware virtual machine, and it can be started on a Dell blade next time, if you like, and it's completely transparent to start on HP's rack-top server.

The separation from the data path means that once the machine starts, the scalent is disconnected from the path. Data that flows out of and out of the machine is not uploaded to the scalent controller, and therefore does not add additional burden to the machine. And, if scalent fails, no server will go down, you just need to restore your static data center.

By balancing VMware3.5 functionality and using Network and SAN integrated scalent software, V/oe creates a portable instance that can be launched from a San where a single boot image can be cloned and deployed to one or more servers. Can be a physical or virtual server. Once the deployment is complete and a failure condition is encountered, the server can be migrated dynamically.

Essentially, Scalentv/oe allows for the organization of physical and virtual servers, and is done almost smoothly. When deployed, the company set the rack once, wiring once, at the same time reconfigure according to the requirements, and do not need to plug the cable or machine, v/oe through the separation of physical connections to complete the work. Even when your servers are moved and booted from the SAN, they can also maintain their address and connectivity.

Scalentv/oe is primarily used to implement cost-effective disaster recovery, it consolidation and deployment, and testing operations solutions. For example, in a business continuity case, scalent reduces the need for each production server to have a separate server. If a production server fails, its application can be immediately brought to another server. Scalent allows a configuration of N to 1 for failure recovery, reducing the cost of continuous planning.

Many technology companies-including EMC, Dell, HP, Sun, VMware, and others-have worked with Scalent to give their solutions. HP, for example, recommends that their customers use Scalent V/oe on Hpbladesystemc-class servers to reduce costs, increase flexibility, and improve performance.
