Windows Server 2. Hyper- V . In particular, major updates to Hyper- V make the hypervisor a viable option for enterprises that previously might not have considered it.

You can create virtual hard disks (VHDs) of 6. TB, thanks to the new VHDX format, which removes the need to use pass- through storage. Put those items together and pretty much any workload can be virtualized with Hyper- V. Fortunately, Windows Server 2. Storage live migration, which enables storage of a VM, lets you move VMs without downtime. Shared- nothing live migration allows VMs to be migrated between Windows Server 2.

Hyper- V hosts with no downtime, even without being clustered and without common storage. These features offer complete mobility of VMs in the data center. However, most organizations have not considered Hyper- V before and might not be clear about how to get started. In this article, I cover some of the basics of getting up and running with Windows Server 2. Hyper- V. For Intel processors, this is the Intel Virtualization Technology (VT) feature; for AMD processors, you need AMD virtualization (AMD- V).

UpdateStar is compatible with Windows platforms. UpdateStar has been tested to meet all of the technical requirements to be compatible with Windows 10, 8.1, Windows 8. WSH: Examples (All) HTA, JScript, VBScript and WSC examples. Click the floppy disk icons to download the ZIPped sources. Click the question mark icons to view the MD5.

Pretty much any server processor manufactured within the past 5 years should have this capability. But if you aren't sure about your hardware, download and run the Coreinfo utility, with the - v switch, from an elevated command prompt. This action will show whether the processor supports virtualization and whether it supports Second Level Address Translation (SLAT)—also called Extended Page Tables (EPT) by Intel and AMD. The output in Figure 1 shows that Intel hardware- assisted virtualization is enabled, which is all we need to get started. SLAT is not required for Hyper- V to function, but it does improve performance.

So the use of SLAT is preferred when possible and is crucial for virtual- desktop environments such as virtualized Remote Desktop Services servers and virtual desktop infrastructure (VDI) environments.

GB or 1. 92. GB of memory are common. But in a lab environment, you need only enough to run your desired virtual load. For Windows Server 2. VHDX format, which not only supports 6. TB VHDs (up from 2.

TB with the old format) but also has been re- architected to offer near bare- metal disk performance. This is true even for dynamic VHDs, which use up only a small amount of disk space initially and grow the file as data is written to the VHD. You also have the option to create a fixed- size VHD. This option is typically used in production environments, both for legacy performance reasons and to avoid the possibility of running out of physical disk space.

That's something that can happen as dynamic VHDX files expand, if proper monitoring is not in place to track the actual physical disk space used. Use the old VHD format only if you need compatibility with older Hyper- V servers, such as Windows Server 2. R2. New to Windows Server 2. SMB 3. 0 file share to store and run VMs.

Using external storage simplifies the backup of virtual environments. As you increase the number of servers, external storage enables a higher utilization of disk space. Descargar Crack Simcity 3000 World Edition Cheats. The use of a central pool actually makes management easier.

External storage is also required if you are going to use Failover Clustering to group multiple hosts into a cluster, allowing VMs to move easily between hosts and automatically restart if a host fails. Every host in the cluster can be patched, without any downtime to VMs. Windows Server 2. Therefore, you need a management connection to communicate over the network. Private virtual switches can allow communications between VMs only, and internal virtual switches can allow communications between VMs and the Hyper- V host, but neither provides communications to the outside world. You therefore need a network adapter for VM traffic.

In a production environment, you likely have at least two network adapters for VM traffic; you can team them to create a single load- balanced, fault- tolerant connection. The option exists to share the network adapter used for VMs with the management OS; in a lab environment, you could use this solution. But ideally, you should separate the management traffic and the virtual network switch that manages VM traffic. If a problem occurs with the virtual switch, you don't want to lose access to the server. Typically, this method is a separate network (although networks that are used for other purposes can—and will—be used if your cluster network is unavailable). In addition to cluster- heartbeat traffic, the cluster network is also used for cluster shared volume (CSV) traffic.

This use allows all the cluster hosts to simultaneously access the same set of NTFS LUNs. The CSV traffic typically consists of only metadata changes. However, in some scenarios all storage traffic for certain hosts uses this network. So when using CSV, you should carve out a separate network for the cluster. So you need to allocate a network for live migration. Nor does it consider the use of multiple i. SCSI network connections or Microsoft Multipath I/O (MPIO) for added fault tolerance.

The situation is different if you use 1. Gbps. There is no sense in having a dedicated 1. Gbps network connection for management traffic or CSV traffic.

Production environments with 1. Gbps likely have two connections, so team them for fault tolerance and then use Quality of Service (Qo. S) to reserve enough bandwidth for each traffic type, in case of contention. Microsoft details these recommendations in its . Team your connections and use Qo. S to ensure bandwidth for different traffic types.

Another option: Some new platforms have converged fabrics with huge bandwidth pipes that can be virtually carved up into virtual network and storage adapters. But should you use Windows Server 2. Standard, Windows Server 2. Datacenter, or the free Microsoft Hyper- V Server 2. From a Hyper- V feature perspective, all are identical.

All three OSs have the same limits, clustering capabilities, and features. The decision depends entirely on which OS you will be running on the Hyper- V host. Hyper- V Server 2. Windows Server guest OS instance rights. This makes sense—the OS is free—and is a great choice if you aren't running the Windows Server OS on the hypervisor. If you're running a VDI environment with Windows 8 VMs, or if you're running only Linux or UNIX VMs, then use Hyper- V 2.

If I wanted to run four VMs with Windows Server, I could buy two copies of Windows Server 2. Standard. Note that you can still run other VMs with a non- Windows Server OS on the same servers. There's no VM limitation, just a limit on the number of Windows Server guest OS rights running on Hyper- V, VMware, or anything else. Consider the price of the Standard and Datacenter versions for your environment. For example, if you're running six or fewer VMs with Windows Server, it's less expensive to buy multiple copies of Standard than to buy Datacenter. But if you're clustering hosts and want to move the VMs, then you have another consideration: Windows Server licenses are tied to a specific piece of hardware and can be moved between servers only every 9. But the hosts are clustered so that I can move the VMs between servers.

Maybe as part of patching, I want to move all the VMs to host B (which would then end up running eight VMs), while I patch and reboot host A. I then want to move all eight VMs to host A while I patch and reboot host B.
