Accusys Storage Ltd. Is a leading innovator of high-performance storage solutions designed for entertainment media and post production markets. Accusys specializes in providing the latest in scalable SAN storage, Thunderbolt share storage and PCIe storage solutions for digital content creation professionals. Redundant array of independent disks (RAID) controller cards allow your computer to communicate with HDDs and SSDs. There are several types of RAID controllers to fit the needs of both large companies with mission-critical systems and small start-ups with limited budgets.

Starting with Windows 10, Version 2004 (OS build 19041.488 or higher), two additional identifiers are available for NVMe storage disk drives which support the STOR_RICH_DEVICE_DESCRIPTION structure:

SCSIt*v(8)p(40)

Where:

• t* is a device type code of variable length

• v(8) is an 8-character vendor identifier

• p(40) is a 40-character product identifier

SCSIt*v(8)p(40)r(8)

Where:

• t* is a device type code of variable length

• v(8) is an 8-character vendor identifier

• p(40) is a 40-character product identifier

• r(8) is an 8-character revision level value

In versions of Windows prior to Windows 10, Version 2004 (OS build 19041.488 or higher), the device ID format for a small computer system interface (SCSI) device is as follows:

SCSIt*v(8)p(16)r(4)

Where:

• t* is a device type code of variable length

• v(8) is an 8-character vendor identifier

• p(16) is a 16-character product identifier

• r(4) is a 4-character revision level value

The bus enumerator determines the device type by indexing an internal string table, using a numerically encoded SCSI device type code, obtained by querying the device, as shown in the following table. The remaining components are just strings returned by the device, but with special characters (including space, comma, and any nonprinting graphic) replaced with an underscore.

The SCSI Port driver currently returns the following device type strings, the first nine of which correspond to standard SCSI type codes.

An example of a device ID for a disk drive would be as follows:

SCSIDiskSEAGATE_ST39102LW_______0004

There are four hardware IDs in addition to the device ID:

SCSIt*v(8)p(16)

SCSIt*v(8)

SCSIv(8)p(16)r(1)

V(8)p(16)r(1)

In the third and fourth of these additional identifiers, r(1) represents just the first character of the revision identifier. These hardware IDs are illustrated by the following examples:

SCSIDiskSEAGATE_ST39102LW_______

SCSIDiskSEAGATE_

SCSIDiskSEAGATE_ST39102LW_______0

SEAGATE_ST39102LW_______0

The SCSI Port driver supplies only one compatible ID, one of the variable-sized generic type codes from the previous table.

For example, the compatible ID for a disk drive is as follows:

GenDisk

The generic identifier is used in INF files for SCSI devices more than any other, because SCSI drivers are typically generic.

Be aware that the SCSI Port driver returns no generic name for sequential access and 'processor' devices.
