  • Il formato VHDX
    check the alignment property for all the VHDs on the system and it should be converted to the optimal 4 KB alignment You create a new VHD with the data from the original VHD by using the Create from Source option By default VHDs are exposed with a physical sector size of 512 bytes This is done to ensure that physical sector size dependent applications are not impacted when the application and VHDs are moved from a previous version of Windows Server to Windows Server 2012 After you confirm that all VHDs on a host are not impacted by changing the physical sector size to 4 KB you can set the following registry key to modify all the physical sector sizes of all the VHDs on that host to 4 KB This helps systems and applications that are 4 KB aware to issue 4 KB sized I Os to the VHDs HKEY LOCAL MACHINE SYSTEM CurrentControlSet Services vhdmp Parameters Vhd1PhysicalSectorSize4KB REG DWORD A non zero value will change all VHDs to report 4k physical sector size By default disks with the VHDX format are created with the 4 KB physical sector size to optimize their performance profile regular disks and large sector disks In WS2012 è stato introdotto il supporto per i Native 4 K Disks avevo parlato di questa problematica nel post Windows 2008 R2 Errore 517 durante il backup Quindi Hyper V può memorizzare i virtual disk su questi dischi come riportato nella Performance Tuning Guidelines for Windows Server 2012 Hyper V in Windows Server 2012 makes it possible to store virtual hard disks This is done by implementing a software RMW algorithm in the virtual storage stack layer that converts 512 byte access and update requests to corresponding 4 KB accesses and updates Because VHD file can only expose themselves as 512 byte logical sector size disks it is very likely that there will be applications that issue 512 byteI O requests In these cases the RMW layer will satisfy these requests and cause performance degradation This is also true for a disk that is formatted with VHDX that has a logical sector size of 512 bytes It is possible to configure a VHDX file to be exposed as a 4 KB logical sector size disk and this would be an optimal configuration for performance when the disk is hosted on a 4 KB native physical device Care should be taken to ensure that the guest and the application that is using the virtual disk are backed by the 4 KB logical sector size The VHDX formatting will work correctly on a 4 KB logical sector size device Di seguito lo schema del formato dei file VHDX Le parti che compongono un VHDX sono strutture che come detto precedentemente supportano large allocation e sono 1 MB aligned Nel dettaglio tali strutture sono L Header region che identifica la posizione della altre region log BAT e metadata table E composta da due header ma che non sono mai
