This section presents requirements for Windows NT–compatible adapters, peripherals, and any devices that use Fibre Channel controller.
143 System includes Fibre Channel controller and peripherals
Fibre Channel is a technology for 1 gigabit per second data transfer that maps common transport protocols such as SCSI and IP, merging networking and high-speed I/O in a single connectivity technology. It is an open standard, defined by ANSI and OSI standards, that operates over copper and fiber-optic cabling at distances of up to 10 km.
If implemented on a server system, to use the native support in Windows NT, Fibre Channel must use the X3T11 Private Loop Direct Attach (PLDA) profile as the storage base. The Physical Layers implementation must comply with Fibre Channel Physical (FC‑PH) Revision 4.3 or higher. For more information, see the web site for the Fibre Channel Association, which is available from the web site at http://www.amdahl.com/ext/CARP/FCA/FCA.html.
Erasable Disk Drives
This section presents the requirements for erasable disk drives provided with a server system or designed for use with Windows NT Server. This category includes 3.5‑inch, 5.25‑inch, and 12‑inch magneto-optical or phase-change drives and media. It does not include CD‑ROM, CD‑R, CD‑Rewritable, and DVD drives or media.
144 SCSI erasable drives support SCSI commands
The following commands or features must be supported by the device’s driver:
Erase (2C): full side and selected block erase
Format requirements reported with Format command
Mode Select: write cache disable
Mode Sense: total spare blocks available, write protect status
Prevent/Allow Medium Removal, Start/Stop Unit
Read (28), Verify (2F)
Reassign Blocks, Read Defect Data
Reserve, Release
Seek (SCSI CDB Opcode – 2B)
Test Unit Ready, Request Sense, Read Capacity, Inquiry
Write (2A), Write and Verify (2E)
Write without pre-erase (for erasable optical only)
Recommended: Inquiry with support for reporting serial number or other unique unit ID should be supported by the device’s driver.
CD-ROM and Other CD Drives
This section presents the requirements for CD‑ROM and DVD‑ROM drives .
145 System includes CD‑ROM drive or other method for installing the operating system
The server system must include either CD‑ROM support or another method to enable the installation (or reinstallation) of the operating system. In a cluster, at least one node must have a CD‑ROM drive.
This section summarizes requirements for CD‑ROM devices. A CD‑ROM drive is not required if another method is provided to support operating system installation. However, if a CD‑ROM drive is present, it must comply with these requirements.
146 CD‑ROM drive provides 8x or higher performance
The CD‑ROM drive must support 1200 KB per second average throughput or higher performance when running in the fully on power state.
147 CD‑ROM drive is CD-Enhanced compatible
The CD‑ROM drive must be able to mount multisession CD‑ROM discs, even if track 1 is Red Book audio. Microsoft recommends use of the Sony ReadTOC method for SCSI‑2 multisession support as noted in the SFF 8020i, Version 2.5.
CD-Enhanced support must be Blue Book compliant, as defined in Enhanced Music CD Specification, Version 1.0.
148 CD‑ROM drive supports specified logical and physical CD formats
At a minimum, the CD‑ROM device must be compatible with the following formats to ensure cross-media compatibility:
Logical formats: CD Red Book, Yellow Book, White Book, and Blue Book
Physical formats: CD‑ROM and CD‑Audio
CD‑E and CD‑R (Orange Book format) can be implemented; however, there are no requirements or recommendations for these formats in this guide.
Note: Any ATAPI CD‑ROM drive designed to play back CD‑I content must return a minimum of two track entries for the READ‑TOC (0x43) command. Drives that do not comply with this minimum requirement cannot play back CD‑I movies.
149 IDE/ATAPI CD‑ROM drive complies with SFF 8020i, Version 1.2
CD‑ROM drives attached to the system must support the hardware and protocols documented in the ATA Packet Interface for CD‑ROMs, SFF‑8020i, Version 1.2 or higher.
Recommended: Support for the READ CD‑DA command as defined in SFF 8020i, Version 1.2.
150 CD‑ROM drive supports multisession and compatibility forms of the READ_TOC command
Both multisession forms (01b and 10b) as well as the compatibility form (00b) of the READ_TOC command must be implemented. This requirement ensures complete support for CD‑ROM multisession capabilities.
151 IDE/ATAPI CD changer meets SFF 8070 specifications
If an ATAPI-compatible CD changer is present that has a capacity for seven or fewer discs, the device must comply with SFF 8070.
152 System BIOS or option ROM supports El Torito No Emulation mode
For server systems that include CD‑ROM and DVD‑ROM devices, the system BIOS or option ROM must support the No Emulation mode defined in El Torito—Bootable CD‑ROM Format Specification, Version 1.0, published by IBM and Phoenix.
