 As explained earlier in the general part of the document, quotas on IOPS throughput for Azure disks exist. The exact quotas are depending on the VM type used. A list of VM types with their quotas can be found [here (Linux)](../../virtual-machines/sizes.md) and [here (Windows)](../../virtual-machines/sizes.md).

 For older Db2 versions, a 512 Byte sector size must be used. Premium SSD disks are 4-KB native and have 512 Byte emulation. Ultra disk uses 4-KB sector size by default. You can enable 512 Byte sector size during creation of Ultra disk. Details are available [Using Azure ultra disks](../../virtual-machines/disks-enable-ultra-ssd.md#deploy-an-ultra-disk---512-byte-sector-size). This 512 Byte sector size is a prerequisite for IBM Db2 LUW versions lower than 11.5.
 
-On Windows using Storage pools for Db2 storage paths for `log_dir`, `sapdata` and `saptmp` directories, you must specify a physical disk sector size of 512 Byte. When using Windows Storage Pools, you must create the storage pools  manually via command line interface using the parameter `-LogicalSectorSizeDefault`. For more information, see [New-StoragePool](/powershell/module/storage/new-storagepool).
