In many cases, these are configured as cluster shared volumes, because a typical Hyper-V environment consists of multinode high availability clusters, with the volume presented to multiple hosts and access controlled by the Windows disk and cluster management features. Search support or find a product: When using directly connected drives, the volume sizing is configured similar to physical server standards. One of the impacts is on thin provisioning. It is common for Hyper-V hosts to have very large volumes to store multiple virtual hard disks.

IBM has not tested these products and cannot confirm the accuracy of performance, capability, or any other claims related to non-IBM products. None of the above, continue with my search. Therefore, no assurance can be given that an individual user will achieve throughput or performance improvements equivalent to the ratios stated here.

Search support or find a product: It is possible to predict the compression benefits by using a new IBM utility called the Comprestimator.

It is easy for IT departments to start creating a lot of VMs rather quickly out of convenience without factoring in the performance impact. Windowws section covers the storage migration for VMs and the different ways to accomplish this. The real capacity is what is actually used by the system and the virtual capacity is its configured maximum size that the volume can expand to.

When in doubt, this is the best source to verify interoperability. Hyper-V Manager virtual machine snapshot However, backup software can also back up applications within the virtual machine, known as application- aware backups.

Provisioning a sequential volume, using the space on only one MDisk, requires the use of command-line interface CLI commands to configure the volumes. During a live migration, both ports will become active. Virtual machines can use one of the several directly connected volume methods. Other company, product, or service names may be trademarks or winddows marks of others. If faster copies are required, the copy rate can be set closer to iwndows however, storage performance must be monitored to ensure impact on other storage operations.

Click Apply to save the switch configuration. FlashCopy works with normal or thin provisioned volumes — for either source or target locations. This tracks and gathers data about the physical processor, memory, network, and storage used by each virtual machine.

As with any Hyper-V resource, bandwidth considerations need to be based on the throughput and capabilities of the physical hardware that the virtual machines rely on. This can improve read request performance, while write- through results in no caching of write requests. Click Apply to save the configuration.

You can find details about the Comprestimator download and additional information at: Additional testing needs to be done with larger settings to validate the best performance setting for the environment.

After a Hyper-V VM has been made highly available, it must be managed from the failover cluster manager. Select the check boxes next to the physical HBA ports to be used.

Some information addresses anticipated future capabilities. The time it takes for the background copy to finish depends on the copy rate, and what other loads are occurring on the storage system.

Because the support levels are wibdows updated, checking the IBM support links provided in this paper is the best way to ensure a given system and software combination is compatible. Most solutions make use of hardware-based VSS if it is available, as it allows the storage system to do the heavy lifting, rather than the operating system. File systems that contain data that is already in a compressed format such as audio, video, and compressed files are not good candidates for Real-time Compression, as the benefits would be minimal.

The IBM support site offers a useful utility for verifying supported combinations of hardware, software, protocols, and operating systems. Microsoft recommends the Hyper-V wimdows server be primarily dedicated to running as a hypervisor, to minimize the additional load and complexity of other services running on it. All customer examples described are presented as dindows of how those customers have used IBM products and the results they may have achieved.
