Fibre Channel Controllers and Peripherals

Fibre Channel Controllers and Peripherals

182. System includes Fibre Channel controller and peripherals

Fibre Channel is a technology for 1 gigabit per second or greater 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 Open System Interface (OSI) standards, that operates over copper and fiber-optic cabling at distances of up to 10 km.

If implemented on a server system, Fibre Channel must use the X3T11 Private Loop Direct Attach (PLDA) profile as the storage base to use the native Windows 2000 sup­port. The Physical Layers implementation must comply with Fibre Channel Physical (FC PH), Revision 4.3 or later. For more information from the Fibre Channel Association, see http://www.fibrechannel.com.

Erasable Disk Drives

183. SCSI erasable drives support SCSI commands

Required

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
  

Recommendation
Recommended: Inquiry with support for reporting serial number or other unique unit ID should be supported by the device’s driver.

CD and DVD Drives

This section presents the requirements for CD and DVD drives.

184. System includes CD or DVD drive or other method for installing the operating system

Required

The server system must include either CD or DVD drive support or another method to enable the installation (or reinstallation) of the operating system.

CD Drive Requirements

This section summarizes requirements for CD drives. A CD drive is not required if another method is provided to support operating system installation. However, if a CD drive is present, it must comply with these requirements.

185. CD drive provides 8x or higher performance

Required

This requirement is intended to set the minimum speed needed for production-level CD reading on Windows platforms. This requirement applies to the minimum read speed (8x) on any production level CD media, such as application software, at any location on the disc. This requirement does not apply to end-user recorded CD data discs, or discs being read in error-correcting, defect management mode.

186. CD drive is CD-Enhanced compatible

Required

The CD drive must be able to mount multisession CD ROM discs, even if track 1 is Red Book audio.

CD-Enhanced support must comply with Blue Book standards, as defined in the MMC 2 standard.

Recommendation

Recommended: Use of the Sony ReadTOC method for SCSI 2 multisession support, as noted in the MMC-2 standard.

187. CD drive supports specified logical and physical CD formats

Required

At a minimum, the CD device must be compatible with the following formats to ensure cross-media compatibility, based on compliance with the Optical Storage Technology Association (OSTA) MultiRead Specification for CD-ROM, CD-R, CD-R/RW, and DVD-ROM Devices, Version 1.11:

• 
  Logical formats: CD Red Book (CD-Audio), Yellow Book (CD-ROM), Orange Book parts II and III (packet writing if recordable), White Book, Blue Book, and Universal Disk Format Specification, Version 1.5 and 2.0
  
• 
  Physical formats: ROM (stamped), and Orange Book part II (CD-R) and part II (CD-RW)
  

Note: Any ATAPI CD drive designed to play back CD I content must return a minimum of two track entries for the READ TOC (0x43) command. These two track entries must be a track 01 entry and a track 0xAA entry for the lead-out address. Drives that do not comply with this minimum requirement cannot play back CD I movies.

188. ATA/ATAPI CD drive complies with MMC-2

Required

CD drives attached to the system using the ATA interface must support MMC-2.

189. CD drive supports multisession and compatibility forms of the READ_TOC command

Required

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 multisession capabilities.

190. ATA/ATAPI CD changer meets MMC-2 standard

Required

If an ATAPI-compatible CD changer is present that has a capacity for seven or fewer discs, the device must comply with MMC-2 standard.
