All Flash Storage. In computing, Serial Attached SCSI SAS is a pointtopoint serial protocol that moves data to and from computerstorage devices such as hard drives and tape drives. Device.

Applies to. Windows 1. Home, Pro, Enterprise, and Education x. Windows 1. 0 for desktop editions Home, Pro, Enterprise, and Education x. Windows 1. 0 Mobile ARMWindows 1. Mobile x. 86. Windows Server 2. Description. Controller Basic Functionality. PCI based host controllers and adapters must support PCI bus mastering as the default setting, and virtual direct access memory DMA services must be supported in the host adapter option ROM. Devices that cannot perform their function without other registry modifications, other than those performed automatically by the device class co installer, are not eligible for the certification. All commands must be passed to the underlying physical device unless the controller is a RAID adapter. If a device returns less data than requested, it must correctly indicate an underrun condition and adapters must handle this in accordance with the WDK adjust Data. Transfer. Length. Non RAID Controller. Miniport drivers other than RAID drivers may not create pseudo devices to be used as targets for management commands for the adapter when no actual LUNs are present. Instead, a SCSI miniports INF must specify the Create. Initiator. Lu parameter under the services Parameters key and set this DWORD value to 1. This may not be done using a coinstaller. Storage miniport drivers do not use this parameter as the adapter may always be used even if no devices are present. Values for storage drivers are documented in the WDK. The following Storage Controller Driver Logo requirement is for the storage controller driver that does not have a matched submission category in the current Windows Hardware Certification Program. Any storage controller with a matched submission category shall be submitted under its matched category. Storage controller driver must be a STORPORT MINIPORT driver. Registry Entries for STORPORT Miniport Drivers STORAGEBUSTYPE must set to Bus. Type. Unknown 0x. For storage controllers, the controller itself must correctly translate the commands and respond in accordance with the applicable SCSI specifications, even if the controller implements other command protocols on a different interface type such as SATA, NVMe, or PQI. Any commands that are not recognized must result in a SCSI check condition with valid sense data. Device. Storage. Controller. Class. Code. Bus attached controllers must implement the correct classsubclass code as defined in the PCI Code and ID Assignment Specification Rev. Applies to. Windows 1. Home, Pro, Enterprise, and Education x. Windows 1. 0 for desktop editions Home, Pro, Enterprise, and Education x. Windows 1. 0 Mobile ARMWindows 1. Mobile x. 86. Windows Server 2. Description. Controller Class Code. Storage host controllers and adapters must meet the requirements for the device protocol used and any requirements related to the device storage bus. Bus attached controllers must implement the correct classsubclass code as specified in PCI 2. Appendix D. This applies to all bus types including, but not limited to, IDE, Fibre Channel, SCSI, and SATA based devices. Any device that implements RAID functionality regardless of whether the RAID implementation is done in hardware, firmware, or in the driver code, must implement the PCI RAID Class Code 0. SATA RAID controller must implement the 0. AHCI class code 0. Non PCI attached storage host controller does not need to report PCI class code. However, it must report the equivalent ACPI Compatibility ID. Device. Storage. Controller. Inf. File. All host adapters must be installed by using Plug and Play mechanisms and require the use of an INF file. Applies to. Windows 1. Home, Pro, Enterprise, and Education x. Windows 1. 0 for desktop editions Home, Pro, Enterprise, and Education x. Windows 1. 0 Mobile ARMWindows 1. Mobile x. 86. Windows Server 2. Description. Controller INF File. All host adapters must be installed by using Plug and Play mechanisms and require the use of an INF. Installation programs must use INF files, must pass the most current Chkinf tool, and can explicitly modify the registry values only by using INF file constructs that meet the Windows certification program requirements.

This value must be set in the miniports INF under the services Parameters key. There is no programmatic way to set it and you may not rely on coinstallers as they do not run under all scenarios.

Windows 1. 0 for desktop editions Home, Pro, Enterprise, and Education x. Windows 1. 0 Mobile ARMWindows 1. Mobile x. 86. Windows Server 2. Description. Miniport Driver Model. Drivers used with storage controllers must follow the miniport driver model. Storage Miniports must comply with all miniport interface definitions as defined in the WDK. Fibre Channel, i. SCSI, SAS, SAS RAID SATA, SATA RAID, SCSI, and SCSI RAID controller drivers must be STORPORT miniports. Monolithic, full port drivers or other types of drivers that do not follow the miniport model are not eligible for the certification. All drivers for physical hardware must be implemented to support Plug and Play. Dark Link Mugen Character. Legacy drivers are no longer supported. Any device that depends on a filter driver for physical disk drive functionality is not eligible for certification. Filter drivers may not be used to bypass any part of the storage stack. For example, a filter driver many not directly access any hardware such as by using HAL calls and filter drivers may not be used to link cache manager to the hardware implementation. Filter drivers may not be used to violate any terms of the certification program. Multipathing drivers may not be tied to specific HBAs except for PCI RAID controllers and must use the MPIO model. Transient or pseudo devices may not be exposed to the system. Drivers that specify NODRV may be used to claim management devices that report as processor, controller, or MSC device types. Such drivers that do not refer to a service entry are not eligible for the certification, but they can be signed. Device. Storage. Controller. Ata.
