Will Your essential communications Pass Its strength Check?

The level of ease and speed with which new applications can be developed has led many organizations to address issues of "the proliferation of servers," only to be confronted with the new edition of "Virtual Machine Extensions".
Here are four practical considerations for the Best virtualization:
1. Only
The main benefit of standardization in all aspects of virtual infrastructure management and provide troubleshooting. Includes the version of software, hardware, server develops standards, labeling configuration grammar, storage and network. The administration is easier, because all parts are interchangeable and in a configuration known beyond learning because it is easier when the number of variables reduced to a minimum. Remember to update the machines with incompatible types or families are not allowed CPU VMotion "VMware is working properly.
The rules must be established and documented during the planning process and then joined during installation. Proposed changes in the environment must be assessed, agreed and documented in a forced "change control procedures."
2. Network optimization
The network is crucial to performance and recovery of virtual infrastructure - that is, part of the movement of end users; the network is the primary means by which manages the virtual infrastructure (through Virtual Center) and media communication frustration tolerance - when using VMotion. VMware recommends that there should be a minimum of four gigabit network adapters ESX 3.x host two attached to a virtual switch for network management (service console and VMkernel VMotion), and two attached to a virtual switch VM network to support virtual machines. In practice, a new partition is recommended. While the placement of multiple NICs to a single vSwitch NIC provides redundancy and fault tolerance, put all cards on the same network that aims to destroy the restrictions on the vSwitch system and can cause congestion of the action. A perfect balance, therefore, must be between the expulsion of the network and traffic segmentation.
3. Allocate storage capacity sufficient to Snapshot
Let snapshot point in time copies of virtual machines that make can be used to test and / or rehabilitation purposes. Instant rules consists of block-level delta last album - consisting of a disk-based ESX backup and write files (maybe) to reflect the changes - as a bitmap of all blocks changed in the base tray. At the same time, can be useful, caution should be used in the use of photography in the background of many of VMware, which consume a significant amount of additional disk space. VMware offers the design, at least 15-20% free space for the snapshot. Alternatively, it may be preferable to use storage-based snapshots, the ability to consume gradually enter.
