Microsoft's Hyper-V will become widespread because it is provided for free as part of the Windows server license. However, this does not mean that IT managers can ignore best practices when managing a virtualized environment. Especially as the virtualization market becomes increasingly commercialized.
Today, vendors offer useful virtualization layers for free and make them easier to manage. Therefore, verifying each vendor's management tool suite and selecting the best tools for your enterprise architecture becomes necessary.
Now there are Hyper-V tools specifically designed for small, medium, and large organizations, which can benefit various environments.
Managing Hyper-V Installations
Virtualization is no longer just for large IT departments. In fact, using a few servers can save small business customers a lot of money. Practical Hyper-V integrated tools can be felt in such scenarios. For example, when managing one or two servers, using the built-in Hyper-V Manager is the most obvious cost-free choice because IT managers can easily create and manage them on a single system.
This seems to be the best choice for small installations, especially if there is no need for clustering. Additionally, small businesses can use the free remote server management tool to create remote connections via a proven remote desktop session to manage any server.
IT departments need to add some virtualization features, such as high availability or physical-to-virtual (P2V) migration, and they should consider investing in System Center Virtual Machine Manager (SCVMM). When you see a mild IT configuration quote, you might spit out your coffee; but Microsoft offers a workgroup version, allowing IT purchases to acquire these functions at a lower cost. The SCVMM Workgroup Edition can manage up to five Hyper-V host servers, so you can enjoy P2V migration while performing live migrations on clustered servers. This is particularly useful for those old, soon-to-be-retired servers, including software with value without reinstallation.
Medium-sized Enterprises Need More Management
IT departments must keep track of dozens or even hundreds of virtual servers, avoiding complete reliance on Hyper-V tools to manage the new virtual layer. Organizations are seeking tools with excellent monitoring and automation capabilities that do not place significant burdens on employees and do not require rebuilding from scratch.
IT departments equipped with the Microsoft System Center Suite will find Virtual Machine Manager interesting. The "single pane of glass" functionality within the system will only be available in the next version; the current version is System Center Virtual Machine Manager 2012, which may be coupled with other parts of the suite, including Configuration Manager (SCCM) and Operations Manager (SCOM). With plug-and-play management packs for monitoring Hyper-V, SCOM is a wise choice for companies that need to quickly reach stable operations without too much chaos. In fact, to fully monitor your virtual machines and hosts, the American Idol top 24 first edition, SCVMM indeed requires appropriate SCOM.
Achieving Enterprise Flexibility with Microsoft Hyper-V
Large IT departments face challenges in integrating virtual machines with existing IT management systems because current management systems are often deeply entrenched in enterprises. In such cases, flexibility is key. Planning an appropriate strategy, IT managers need to find a good combination of management tools.
Major vendors provide vendor-neutral options for virtual environments, not only for managing and monitoring Hyper-V but also other virtual layers such as VMware ESX and ESXi. For instance, Quest's vFoglight offers an integrated option for monitoring the virtual layer, effectively distributing workloads across available computing resources. Therefore, in scenarios requiring interaction with thousands of virtual machines, it is crucial to find tools that support and maintain variable workloads and quality of service requirements.
Large enterprises have more needs to seek functions that smaller enterprises do not consider, such as automated Hyper-V host deployment, rapid virtual machine backup, and compatibility with shared storage. For example, HP's IO Designer supports automated Hyper-V host deployment and verifies the availability of all required resources for the target blade server. It also supports a self-service interface, making it easy for administrators to install new Hyper-V hosts.
Beyond Single Tools
There are many toolsets available that support Hyper-V, a great change compared to the sparse support available two or three years ago. From hardware consolidation to monitoring management, these add-ons are practical once you exceed a few servers in a mixed environment or when the enterprise needs features like live migration.
But don't forget the typical single-function tools in a system administrator's toolbox. These include virtual hard disk converters, processor probes, and monitoring gadgets. These tools will still be needed in a virtual server environment.
