It should have sufficient memory. It has been running from November But we have serious performance issue. The server works perfectly, but within a week it slows incredible down. We are only 7 users. We have a lot of Outlook activity and share our mailbox across all coworkers, so the OST files are big — GB for 10 mailboxes. If I rebuild the index everything works fine for the week or so.
There is a lot of disk activity on the searchindexer. Seems I need to move the Windows. Is this a common scenario? What type of disks speed did you use? What type of RAID? Here you can visit the store and purchase an upgrade. Although this document does not provide a complete list of Hyper-V compatible hardware, the following items are necessary:. After checking the operating system and hardware requirements above, verify hardware compatibility in Windows by opening a PowerShell session or a command prompt cmd.
If any item returns No , check the requirements listed in this document and make adjustments where possible. If all OS, hardware and compatibility requirements are met then you will see Hyper-V in Control Panel: Turn Windows features on or off and it will have 2 options. Feedback will be sent to Microsoft: By pressing the submit button, your feedback will be used to improve Microsoft products and services. Privacy policy. Therefore, before performing installation or upgrades, it is critical to ensure that the Startup RAM value meets the minimum memory requirements of the selected OS.
When setting Hyper-V Dynamic Memory limits for a particular VM, it is critical to keep in mind that your infrastructure may be subjected to memory leaks. Memory leaks imply the gradual loss of available memory as a result of incorrect memory allocation.
It usually occurs when an application fails to release memory which was provided only for temporary use. If the issue is not detected before any serious damage is done, the OS memory can become exhausted and the application will eventually fail. In order to mitigate negative effects of this issue, it is recommended that you install a monitoring tool e. RAMMap and scan the entire infrastructure for any inconsistencies and detect unusual cases of memory usage by running applications.
Also, such tools can help you determine the minimum and maximum RAM values which would be most appropriate for this particular VM. To ensure that Hyper-V Dynamic Memory functions as required, it is recommended that you determine limits which the system cannot exceed. One Hyper-V Dynamic Memory best practice is to assign the appropriate Memory Buffer value, which specifies how much extra memory should be made available for a selected VM.
At the same time, the Memory Buffer value should be set low if there is a running application that requires a large amount of physical memory. With the reduced Memory Buffer value, you can be sure that the available memory is not completely consumed by a single VM. Moreover, if a large amount of memory has already been assigned to the VM, it is unlikely that it will ever require extra memory. Thus, it makes more sense to share unused memory resources with other VMs which need it more.
In order to keep your Hyper-V environment stable and secure, make sure that your Hyper-V hosts install all updates and security patches when required. The main purpose of Microsoft updates and security patches is to deal with the issues that have been identified in the system.
Even though the feature was enabled on the VMs, it still continued to fail. Due to this fact, Microsoft released the hotfix in order to remove the issue and ensure that the functionality works as required. Production workload increases considerably during working hours, which eventually affects Hyper-V performance as well as resource allocation and memory utilization.
As one of Hyper-V Dynamic Memory Best Practices, it is recommended that you monitor the changes in memory usage throughout the course of the working day. By detecting when the cycles of high and low memory usage typically occur, you can learn how to use Hyper-V Dynamic Memory to your advantage. Even though Hyper-V Dynamic Memory is an extremely helpful feature which improves the use of physical memory, there are some cases when static memory allocation is the preferable option.
For example, some applications perform better if they have a pre-determined amount of RAM which they can use without interruption.
