In server virtualization, in order to maintain the optimal utilization of physical resources and easily add new virtual machines, IT must be able to move virtual machines without impacting the business directly when needed. The ability to move a virtual machine across a hyper-V host was first seen in Windows

One, Introduction LVS (Linux virtual Server) is a virtual server in the Unix-like system and is one of the best projects in China to contribute to open source organization.

What is a virtual disk? What are the characteristics of virtual disks in Windows Server R2?A virtual disk is a separate file that is placed on a physical hard disk. The purpose of the virtual disk file is to capture the full state of the

that you try to shut down the firewall first. 5. Shut down the intranet server host firewall, because the local network is a trusted zone, the firewall does not prevent the local network access, if the access to the source address is the external network address (untrusted zone address), it may be blocked by the firewall and inaccessible. 6.

1. Application-tier virtual servers are implemented using application-tier forwarding, which is equivalent to a proxy server, which is often referred to as a virtual server. Implementation: The use of Apache Proxypass can be implemented on the virtual

. For example, suppose a hyper-V host connects two sans: one for a production SAN and one for a test SAN. The host connects to each SAN through two physical Fibre Channel ports. In this example, you can configure two virtual sans: one named "Bjcloud Product San", with two physical fibre Channel ports connected to the production San, and another named "Bjcloud Test San", with two physical fibre Channel ports connected to test the SAN. You can use the s

With multiple Web sites configured on the same physical server, many users choose to add multiple IP addresses to the server and then point each Web site to a different IP address. This approach is feasible, but as the IP address (mainly refers to the IP address in the Internet) more and more scarce resources, the drawbacks of this approach is more obvious. In fact, in IIS 5.0 and IIS6.0, users can simply a

Hyper-v Server Virtual Fiber ChannelThe new virtual Fiber Channel (VFC) in Windows Server 2012/R2 enables Hyper-vclient to access the physical storage host bus adapter (HBA) installed on the Hyper-V Server ). Generally, Hyper-VPC is equipped with storage adapters. However, w

The principle of WWW server virtual host The WWW server virtual host refers to a WWW server that uses a physical machine to act as multiple host names. For example, by a machine to provide http://www.company1.com, http://www.company2.com and other WWW services, and browsing

Server virtualization requires only a small amount of hardware resources to run multiple applications and operating systems, allowing users to quickly allocate new resources as needed. However, these flexibility also causes network and security managers to worry that security risks in the virtual environment will spread throughout the network. If a problem occurs with the

The Windows Server 2012/r2 Hyper-V Virtual Switch (vSwitch) introduces a number of user-requested features to enable tenant isolation, communication shaping, preventing malicious virtual machines, and more easily troubleshooting problems.
