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 DataTransferLength).

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 CreateInitiatorLu 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 that 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 - STORAGE_BUS_TYPE must set to BusTypeUnknown (0x00).

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.

Description

Controller Class CodeStorage 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 class/subclass code as specified in PCI 2.3, Appendix D. This applies to all bus types including, but not limited to, IDE, Fibre Channel, SCSI, and SATA-based devices. Any device which 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 (01/04) and not use the interconnect class code (for example, a SATA RAID controller must implement the 01/04 class code and not the AHCI class code 01/06/01). Non-PCI attached storage host controller does not need to report PCI class code. However, it must report the equivalent ACPI Compatibility ID.

Description

Controller INF FileAll 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. Changes can be made only under the following keys:

TimeoutValues under the class driver services keys (Disk and Tape).

SpecialTargetList only for SCSIport implementations.

Device's service key (must be HKLM\System\CurrentControlSet\Services\ and the Parameters\Device subkey under that).

Signal BusChangeDetected on any link transition or detection of a hot-plug event. A limited settling is allowed before this is signaled, but it must be settable through a registry parameter.

Implementation of the BusType registry DWORD to correctly set the interface type in accordance with the enumeration in NTDDSTOR.H (see the WDK).This value must be set in the miniport's INF under the service's 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.

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, iSCSI, 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. 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.

Target Feature	Device.Storage.Controller.Raid.ContinuousAvailability
Applies to	Windows Server 2012 R2 x64 Windows Server 2008 Release 2 x64 Windows Server 2012 x64

Description

When the device and driver are configured in multiple nodes in a Windows Failover Cluster, each node must support as a minimum dual-active access, defined as full read/write functionality for at least one LUN that has capability for being failed over to another node in the cluster. Specifically not allowed is to only support passive operation where the device and driver operates only in a standby mode until the cluster fails over a LUN from another node.

Design Notes:

For this dual-active access, LUNs do not need to provide full, performant read/write functionality to all nodes in the cluster. Access from other nodes only needs to be supported as required to support a valid Windows Failover cluster.

Specifically, it is desirable but not required to support simultaneous, shared access to a LUN from multiple nodes in the cluster.

Device.Storage.Controller.Raid.ContinuousAvailability.LunAccess

Device and driver must meet requirements for accessing LUNs in a Windows Failover Clustering configuration

Target Feature	Device.Storage.Controller.Raid.ContinuousAvailability
Applies to	Windows Server 2012 R2 x64 Windows Server 2008 Release 2 x64 Windows Server 2012 x64

Description

When a node in a Windows Failover Cluster fails over its resources, either planned or unplanned (e.g., resulting from a node crash or node power failure), the device and driver must meet the following requirements:

All data from successfully acknowledged writes prior to failover must be preserved and accessible from surviving nodes. Specifically, data corresponding to write operations sent to the device and driver on the failing node prior to the start of failover of its LUNs (i.e., after the corresponding RAID controller on a surviving node receives a persistent reservation request corresponding to the LUNs from the failed node) that have been acknowledged by the driver as completed must be accessible after failover completes from a surviving node. In addition, any data that may be pending from unacknowledged writes at the start of failover must not change data subsequently written to the device from a surviving node.

When the LUNs supported by the RAID controller on the failing node stop being accessible (i.e., stop acknowledging and processing I/O requests), the LUN must be made accessible (i.e., acknowledge and process I/O requests) by at least one other node in the cluster with a maximum delay of 5 seconds. This time limit must be supported for up to 100 LUNs or the maximum number of LUNs supported by the controller, whichever is smaller.

During normal operation (i.e., not during failover) in a Windows Failover Cluster, the device and driver must meet the following requirement:

All I/O requests to any LUN supported by the RAID controller must complete within 25 seconds. This time limit must be supported for up to 100 LUNs or the maximum number of LUNs supported by the controller, whichever is smaller.

Target Feature	Device.Storage.Controller.Raid.ContinuousAvailability
Applies to	Windows Server 2012 R2 x64 Windows Server 2008 Release 2 x64 Windows Server 2012 x64

Description

Device and driver must support commands from SBC-2 (or later) regardless of the drive interface implemented.

Device and driver must support, at a minimum, one of: RAID1, RAID 5, RAID6 or RAID 1/0, or an equivalent feature that supports full LUN functionality in the event of failure of a single data drive.

Device and driver RAID implementation must provide a solution to prevent data loss due to the RAID write hole failure mechanism. (See Design Notes for definition of the RAID write hole failure mechanism.)

Design Notes:

If there is a system or controller failure during active writes, the erasure code information of a stripe (e.g., parity) may become inconsistent with the data. Data loss may result if this incorrect erasure code information is subsequently used to reconstruct the missing block in that stripe. This problem is known as the RAID write hole .

Examples of typical solutions for the RAID write hole problem are to provide mechanisms to detect and recover from an interrupted update-in-place operation or to avoid update-in-place semantics

Additional Information

Business Justification	By conforming to the features and standards mentioned in the detailed description section of this document, Windows will be capable of efficiently and securely utilizing NVMe devices. Deallocate will allow easy removal of data from the device without incurring additional I/Os, thus prolonging the expected life of the flash. Flush for volatile caches is required for Bitlocker scenarios that include storage caches. It is necessary to have the capability to synchronize all data from a caching layer to the final storage medium. Asynchronous Event Requests allow Windows to retrieve health information about the device that may indicate errors and failures. This capability yields better error handling and preventive measures can be taken to minimize the risk of data loss.

Additional Information

Business Justification	Some Hard Disk Drives report the physical sector size of the disk incorrectly. For example, the drive is released a "4K" drive without reporting that it is indeed a 4K drive. Applications use the reported physical sector size as a notion of atomicity and perform I/O based on this. The most basic example is a database-style application will only store one commit record within the unit of atomic write for fear of loss if power is lost or if a physical sector becomes physically bad. When the reported physical sector size is not the unit of atomicity, serious reliability concerns can arise in scenarios where power is lost such as:Applications can fail to recover, and users will need to restore from backup.Applications can fail to recover, but the application will need to perform a lengthy consistency check.Corruption of metadata, log file data, user data, or even data from other applications.

Description

Required: All Microsoft MPIO device-specific modules (DSMs) must be Windows Hardware Certification-qualified and support registering and unregistering persistent reservations across all paths.Design Notes:

All host bus adaptors (HBA) used on failover cluster nodes can use only a Windows Hardware Certification-qualified miniport driver based on the Storport miniport model.

All multipath I/O solutions leveraged on highly available failover clusters must be based on Microsoft MPIO.

It is recommended that in addition to the standard HCT qualification all solutions are also validated with the "Microsoft Cluster Configuration Validation Wizard" (ClusPrep) tool.

FC, iSCSI, and particularly serial-attached SCSI (SAS) failover cluster solutions cannot be built on RAID HBAs where cache and/or RAID configuration is machine/node specific. The RAID set information and hardware cache must reside in a single shared point that lives in an external storage controller.

SAS, FC, and iSCSI have no restrictions as to the number of nodes they support (which currently is 8nodes).

Note: Legacy parallel-SCSI server clusters were restricted to a maximum size of 2nodes.

Only SAS devices using the Serial SCSI Protocol (SSP) transport will be supported on failover clusters (including SAS JBOD or any SAS SSP RAID systems). SATA devices attached to a SAS domain must be part of a RAID system.

SATA direct attach and SATA JBOD is not supported; the system must include RAID.

If the system disks are attached to a bus type that is not a valid type for shared storage (something other then FC, iSCSI, or SAS), then the system disks and shared storage must be on separate physical controllers/host bus adaptors.

The device shall implement a mechanism to self-pin boot files, i.e. anything prior to Windows becoming active, into the top priority level of the cache. Specifically, the drive shall self-pin in this fashion from power on until the Hybrid Information Log Page is read. The drive should cease self-pinning to the top priority after 160 MB of data has been pinned. All other self-pinning the drive performs shall occur at priority 0.

Cache Size

The hybrid cache has to provide at least 12 GB (12x2 Bytes) of useable capacity to the host.

6 priority levels (0 through 5)

The device must support at least 6 priority levels. No data placed in the cache by the host shall be evicted from ranges 1 through 5 by the device, unless Windows specifies it through calls to evict, demotebysize or trim, or issues further I/Os with priority > 0 to a full cache (i.e. cache churning).

Cache Page Replacement

The drive shall repurpose cache pages of lower priorities to satisfy I/Os at higher priorities, starting with the lowest priority. For example, if the cache is full with 25% at priority 0, 50% at priority 2, and 25% at priority 3 and a priority 3 read/write occurs that is not in cache, a priority 0 cache page should be repurposed to accommodate the priority 3 LBA that was read. Once all priority 0 cache pages are repurposed, priority 1 and 2 pages will be repurposed respectively. If no lower priority pages are available, priority 3 should repurpose pages first that are chosen by a LRU-like algorithm.

Update Priority On IO (Read/Write)

Priorities associated with LBAs in the cache must be updated on any subsequent read or write to that LBA, from any valid priority to any valid priority. In addition, if a read or write is issued to an LBA range that currently does NOT reside in cache, then it shall be placed in the cache at the specified priority (provided there is room in the cache or there are blocks of lower priority that can be evicted in case of a full cache).

Trim

The device shall support trim as defined in the Windows 8 Hardware Certification Requirements under Device.Storage.Hd.Trim.BasicFunction.

Non-volatile Cache Performance:

Sequential Read:>= 200 MB/s3,200 I/Ops @ 64 KB

Sequential Write:>= 80 MB/s1,280 I/Ops @ 64 KB

Random Read:>= 10 MB/s2,560 I/Ops @ 4 KB (Queue Depth = 1)

>= 20 MB/s5,120 I/Ops @ 4 KB (Queue Depth = 8)

Random Write:>= 5 MB/s1,280 I/Ops @ 4KB (Queue Depth = 1)

>= 10 MB/s2,560 I/Ops @ 4KB (Queue Depth = 8)

Latency:

Setting dirty high and dirty low thresholds shall complete within 1.5ms.

This command can be completed asynchronously.

I/O that carries priority information should not be significantly slower than I/O without priority information. A read or write that has a priority assigned must not incur a latency penalty larger than 10% of an identical I/O without priority information. Achieving this on 95% of all I/Os is acceptable with the penalty never exceeding 100% of a non-priority I/O.

HybridDemoteBySize and HybridChangePriorityByLBARange must return within 5ms. A possible asynchronous implementation of these commands is acceptable.

The following functionalities and requirements have to be supported by the device and refer to the Hybrid Information Feature (Version 14, Oct. 29, 2012) worked on by SATAIO:

13.7.5.4.11 MaxPriority Behavior

The MaxPriority Behavior bit must be set to 0.

13.3.15 Enable/Disable Hybrid Information

13.6.5.4.13 Hybrid Control

Enable/Disable Caching Medium

Windows must have the ability to enable and disable the hybrid cache. Upon disabling the hybrid cache, all dirty data in the cache has to be synchronized with the final storage medium.

Dirty Low Threshold

Dirty High Threshold

Dirty data should be synchronized in ascending order of priority, i.e. priority 0 dirty data should be synchronized before priority 1 dirty data is synchronized.

13.6.5.4.7 Hybrid Demote By Size

Hybrid Information feature related Logs

The device must enable Windows to read the hybrid log pages and return sensible information. In other words, General Purpose Logging is required and the version number shall be set to 0001h. Specifically:

13.7.9 Word 0x12 of General Purpose Log Directory shall be set to 1 , indicating that NCQ NON-DATA log is supported.

13.7.10 Word 0x13 of General Purpose Log Directory shall be set to 1 , indicating that NCQ SEND AND RECEIVE log is supported.

13.7.12 Word 0x14 of General Purpose Log Directory shall be set to 1 , indicating that NCQ HYBRID INFORMATION log is supported. Windows has to be able to determine the following:

Caching Medium Health Status

Dirty Low Threshold

Dirty High Threshold

Maximum Hybrid Priority Level

Max Priority Behavior

NVM size

Max Eviction Commands.

Max Eviction Data Blocks

For each Priority level:

consumed NVM size fraction,

consumed Mapping Resources Fraction

consumed NVM Size for Dirty Data Fraction

consumed Mapping Resources for dirty data fraction

13.6.5.4.1 Hybrid Evict

The LBA range specified by the Evict command shall be targeted to the primary medium like a regular write. The host will ensure consistency if necessary by issuing a subsequent flush command.

13.6.5.4.10 Hybrid Change By LBA Range

If Hybrid Change By LBA Range is called on an LBA that currently does not reside in the caching medium, the device shall not fetch it from disk.

Additional Information

Business Justification	By providing the aforementioned functionality and hardware support, Windows will be capable to properly take advantage of the non-volatile cache that exists on hybrid devices. A large non-volatile cache of 12 GB will allow Windows to reduce flash wear, since less churn will occur in the NVC. Additionally, hibernate and hiberboot scenarios can be supported very well without negatively affecting scenarios such as application launch and run-time / write caching. Relatively fine-grained cache management becomes possible through the support of ChangePriorityByLBARange. Not only app launch, resume and boot performance is improved due to less cache misses but also flash longevity and endurance. Updating priorities on all I/Os (reads & writes), for example, allows Windows to only update LBA ranges that are intended to change priority level in the cache. All other cache contents do not have to be touched, which keeps metadata updates on the device to a minimum, thus prolonging the flash s life expectancy. Trim has a similar effect, whereby a trimmed region can simply be discarded by the device, as opposed to moving the region to priority 0 and have it synchronized. The absence of trim would incur more flash I/O and wear, as well as disk I/O for synchronization that could be avoided. Bitlocker will be positively affected by the Evict command, since data can be synchronized periodically during encryption as opposed to potentially forcing the entire flash area onto the disk platter at the end of a Bitlocker conversion cycle, or alternatively, completely disabling the entire hybrid feature and disabling the cache for the duration of the encryption.

Description

SCSI Primary Commands-3 (SPC-3), SCSI Primary Commands-4 (SPC-4) and SCSI Block Commands-3 (SBC-3)

Devices must comply with SCSI Primary Commands: support commands listed as mandatory in the SCSI Primary Commands (SPC-3 or later). In addition, each device type must implement the mandatory command set for that type (SBC-3 for block devices and so on).

For SCSI INQUIRY and REPORT LUNS commands:

All devices must support the SCSI INQUIRY command.

Multi-LUN devices must always respond to an INQUIRY command sent to LUN 0 even if LUN 0 is not implemented. This can be indicated by returning the Device Type Qualifier of 3.

All multi-LUN devices must support the REPORT LUNS command as defined in SPC-2 or later.

Windows supports only single-level logical unit numbers up to 255; see SAM-3. Use of any other format will be incorrectly interpreted, and the device may not be available or data corruption will occur.

All standard INQUIRY data must be correctly set for the device capabilities.

VERSION Field must be 04 or greater. For SAS, this field must be 05 or greater.

Drives with attached media changers must set the MChgnr bit in the standard inquiry data.

Multi-LUN units must return valid REPORT LUNS data for LUN 0.

If LUN 0 is not an accessible PERIPHERAL DEVICE TYPE, the PERIPHERAL QUALIFIER shall be returned as 1. SCSIport will not enumerate the entire target device if a qualifier of 3 is used. It is strongly recommended that LUN 0 not be type 0 because it must be exposed to all initiators. Type 0 is permitted only if the array can map different logical units to LUN 0 for each initiator.

If a device has more than one port, MultiP bit must be set and page 83h descriptors must correctly reflect the port information.

Vital Product Data (VPD) pages:

Page 00h (Supported Pages VPD Page) is required.

Page B1h (Block Device Characteristics VPD Page) is required.

Page 80h (Unit Serial Number VPD Page) is required.

Page 83h (Device Identification VPD Page) is required. For VPD Page 83, at least one type-3 or one type-2 descriptor must be returned for each logical unit, the value must use Code Set 1 (Binary), the value must be unique for that logical unit, and it must be the same value regardless of the path or port responding to the request. Appropriate descriptors for multiport devices are required in addition to that mandatory descriptor. Devices that support aliases must also support the corresponding descriptor types. Vendor-specific device identifiers, if present, must use type 0 and must follow the specified format, including correct page length;

Vendor-specific identifiers are not a substitute for the mandatory type 2/3 descriptors. All device identifiers must conform to formatting rules set forth in SPC-3 or later, even if the device claims only conformance to a previous release.

Device must comply with SPC-3 section 7.6.3 Device Identification VPD page 83h.

At least one identification descriptor must have the IDENTIFIER TYPE field set to:

2h (EUI-64-based) as defined in 7.6.3.5

3h (NAA); or as defined in 7.6.3.6

8h (SCSI name string) at defined in 7.6.3.11

SCSI Mode Sense Command and Pages

MODE SENSE (6) is mandatory for all devices except RBC devices, which implement MODE SENSE (10). The DBD bit must be supported.

Mode Page 3Fh (Return all pages mode page) is mandatory.

Device type-specific pages listed in the device-specific sections of this document.

Additional commands for all devices are as follows:

All devices must support the TEST UNIT READY and REQUEST SENSE commands.

Block Storage (Disk and RAID) Devices

Block storage (disk and RAID) devices must comply with the following requirements:

SCSI block commands (SBC) or later (RBC for 1394). These requirements apply to any device reporting as Device Type 0, including logical units exposed by a RAID controller or subsystem.

Block Devices must support the SCSI START STOP UNIT command to decrease power consumption.

READ CAPACITY (10) command. If a device has more than 2^32 - 1 sectors, a value of 0xFFFFFFFF must be returned for the RETURNED LOGICAL BLOCK ADDRESS field and the READ CAPACITY (16) command must be supported (see below).

Any change to capacity must set a unit attention condition of CAPACITY DATA HAS CHANGED for all initiators with access to the logical unit.

READ(10).

WRITE(10). Support for force unit access (FUA) is mandatory for individual physical disk drives or RAID controllers that contain volatile (non-battery-backed) cache memory and must cause the data sent with this command to be committed to physical media before the command completes.

REASSIGN BLOCKS (hard disks only). RAID controllers that handle bad block replacement should succeed this command.

VERIFY (10).

START STOP UNIT. This command must not perform any other action, such as path failover.

SYNCHRONIZE CACHE (10) (no optional fields are used). For a physical disk drive, this command causes all data in the write cache to commit to physical media if write caching is enabled. Failure to follow this can result in data corruption.

Mode pages:

Mode Page 08h (Caching mode page) with the following bits must contain valid information: WCE (Write Cache Enable), CACHE SEGMENT SIZE, and NUMBER OF CACHE SEGMENTS (optional). RBC devices support Page 6 instead of Page 8 (WCD, WRITED, FORMATD, and LOCKD bits).

If a device supports disabling write caching through the use of the WCE bit, this bit must also be reported as changeable and be supported by a MODE SELECT operation which modifies it. The status of the write caching must be visible by reading Mode Page 8. Vendors can implement caching policies outside of the limited SBC ones, and disabling of write cache does not need to be through this mode page.

Mode Page 0Ah (Control mode page) is required.

Mode Page 1Ah (Power Condition mode page) is required

Disk devices that support greater than 2-TB logical units (including 1394 disks). Devices must conform to SPC-3 and must implement all of the following in accordance with the SCSI Block Commands-2 (SBC-2) specification:

READ CAPACITY (16)

READ (16)

WRITE (16) FUA (bit must be supported if a volatile cache is present on the device)

VERIFY (16)

REASSIGN BLOCKS. LONGLBA field must be supported.

Erasable SCSI Disk Devices

Erasable SCSI disk devices must also support the following commands or features:

ERASE: Full-side and selected-block erase.

Format requirements reported with FORMAT command.

MODE SENSE (6) Total spare blocks available, write protect status.

PREVENT ALLOW MEDIUM REMOVAL and START STOP UNIT.

REASSIGN BLOCKS and READ DEFECT DATA (10).

WRITE without pre-erase, for erasable optical only.

"Command completion time" is defined as the time between a command leaving the Microsoft port / miniport driver and the command completion being returned to the Microsoft port / miniport driver. If the command is failed with error status, this time also includes the subsequent Request Sense command leaving the Microsoft port / miniport driver and the Request Sense command completion being returned to the Microsoft port / miniport driver.All the command execution time performance measurement should be performed on media conforming to media physical layer standard specification from associated committees - i.e. DVD Forum, BDA, DVD+RW Alliance. Also, they should be performed under normal temperature and humidity operational condition as declared in the device specification.Note: Read-Only drives will be retired from the Windows certification Program on June 01, 2010. Hence, certification requirements and tests will cease to exist for Read-Only drives on June 01, 2010. Partners who wish to receive Windows certification on systems with Read-Only drives would still be a able to. However, the Read-Only drive would fall under the "unclassified" category of devices. 1: Transfer length for the read and write performance tests is equal or smaller to a single ECC block (32 or 64 KB depending of the current media type, i.e. 64KB for CD and BD, 32KB for DVD).2: Performance tests may be exercised at any speed reported as supported by the device, including 1x media speed if so reported as supported.3: Drive must make use of write buffer and shall not delay command completion by any form of media access. If write buffer is full, drive must fail the write command with long write in progress sense information (02h/04h/08h). 4: The first hundred read I/O commands after media arrival or resume from StandBy power state or Set Cd Speed or Set Streaming are permitted a delay up to a cumulative total of 60 000 msec to complete to allow for additional spin-up time. These commands individually may take any duration up to a limit of 7 000 msec, but the cumulative time to complete all hundred commands shall not exceed 60 000 msec. Only the time between when a read command is sent to the device and that read command is completed by the device is accounted for, the time between two successive read commands is not accounted for (i.e. host delays are not measured).6: The list of disc structure codes is limited to; physical format information (Format = 0x00, Address = 0), DVD-RAM medium status (Format = 0x09, Address = 0), DVD+RW write inhibit DCB (Format = 0x30 Address = 0x57444300), write protection status (Format = 0xC0 Address = 0)7:Dual Layer Write profile will be required on 1 June 2010 for Blu-Ray drives of 9.5 mm height and smaller as well as DVD drives 7mm height and smaller. This ends the previous exception for these form factors.
