ESX Server Network and Storage Connectivity As a result, virtual machines have networking properties consistent with physical machines. #CHANGEING A RAW DISK MAP IN VMWARE FROM PHYSICAL TO CIRTUAL MAC#ESX Server virtual switches also support VLANs that are compatible with standard VLAN implementations from other vendors.Ī virtual machine can be configured with one or more virtual Ethernet adapters, each of which has its own IP address and MAC address. You can also build complex networks within a single ESX Server host or across multiple ESX Server hosts, where virtual switches allow virtual machines on the same ESX Server host to communicate with each other using the same network protocols that would be used over physical switches, without the need for additional networking hardware. With virtual networking, you can network both virtual machines and physical machines in a consistent manner. These networking capabilities are provided by VMware ESX Server and managed by VMware VirtualCenter. VMware infrastructure provides a rich set of networking capabilities that well integrate with sophisticated enterprise networks. Note For more information about AMD Processors that support this technology, refer to the following URL: įor more information about Intel Processors that support this technology, refer to the following URL: Expediting this revolution is the introduction of more powerful x86 platforms built to support a virtual environment, namely the availability of multi-core CPU and the use of AMD Virtualization (AMD-V) and the Intel Virtualization Technology ( IVT). The ability to break the link between physical hardware (such as CPU, memory, and disk) from an operating system provides new opportunities to consolidate beyond the physical level and to optimize resource utilization and application performance. Mainframe legacy systems have been "virtualized" for many years, employing logical partitions (LPARs) to achieve greater resource utilization. Technologies such as virtual local area networks (VLANs), virtual storage area networks (VSANs), and virtual network devices are widely deployed in today's enterprise data center. Virtualization of network, storage, and server platforms has been maturing over time. As a result, data center applications are no longer bound to specific hardware resources thus making the application unaware of the underlying hardware, yet viewing the CPUs, memory, and network infrastructure as shared resource pools available via virtualization. Server virtualization is a technique that allows the abstraction of server resources to provide flexibility and optimize usage on a standardized infrastructure. IT groups are considering the data center facility, the servers it houses, and network components as a pool of resources rather than unrelated assets "siloed" to resolve specific business requirements. #CHANGEING A RAW DISK MAP IN VMWARE FROM PHYSICAL TO CIRTUAL SOFTWARE#IntroductionĬurrently, there are efforts to consolidate and standardize the hardware and software platforms comprising the enterprise data center. This document is intended for network architects, network engineers, and server administrators interested in understanding and deploying VMware ESX Server 3.x hosts in a Cisco data center environment. The document provides details regarding the internal constructs of the ESX Server and their relation to external Cisco network devices are discussed. It documents a set of suggested best practices for deploying VMware Infrastructure (VI) 3.x and VMware ESX Server 3.x in a Cisco network environment. This document is a collaboration between Cisco and VMware. VMware Infrastructure 3 in a Cisco Network Environment
