  1. Advanced SCSI Programming Interface

    nofootnotes date June 2009 In computing , ASPI Advanced SCSI Programming Interface is an application programming interface originated by Adaptec which standardizes communication on a computer bus between a SCSI host adapter on the one hand and SCSI and ATAPI peripheral s on the other. History ASPI was developed by Adaptec in the early 1990s. It was originally designed to support SCSI drives. Support for ATAPI interface such as IDE was later added. Microsoft licensed the interface for use with Windows 9x Windows 9x series . At the same time Microsoft developed SCSI Pass Through Interface SPTI , an in house substitute that worked on the NT platform. Microsoft did not include ASPI in Windows 2000 XP, in favor of its own SPTI. Users may still download ASPI from Adaptec. A number of CD DVD applications also continue to offer their own implementations of ASPI layer.

The phrase has several common uses Printmaking An image may be through and through in the following cases ink or paint has penetrated to the other side inlaying with another material, stained glass , patchwork , woodworking woodwork , linoleum , marble , etc. Wikt carving carving out e.g. wood carving , cutting out, perforation this may concern the outside shape , shaped Punchhole hole s, and patterns of holes e.g. in a punched card also a passport may have its number perforated in the pages, to make forgery more difficult . embroidery etc. Through and through images are more durable they do not easily wear off. In the case that the image can be viewed from the other side, we see the mirror image , just like in the case of a Transparency optics transparent image, such as a drawing on a transparent sheet. A sheet with a through and through image is Chirality mathematics achiral . We can distinguish two cases the sheet surface with the image has no axis of symmetry parallel to the axis of rotation the two sides are different e.g. U on a page rotated L R the sheet surface with the image has an axis of symmetry parallel to the axis of rotation the two sides are the same e.g. C on a page rotated L R Forensics Through and through is also used in forensics to describe a bullet that has passed through a body, leaving both entry and exit wounds.

  1. SCSI mode pages

    SCSI SCSI target target devices provide a number of SCSI mode pages . These can be interrogated by a SCSI Mode Sense Command Mode Sense command and set by a SCSI Mode Select Command Mode Select command . The Mode Sense and Mode Select commands include a 6 bit address field, allowing for 64 possible mode pages. A description of many of these page codes is included below. Note that any given SCSI device type will only support a subset of the possible page codes, and some page codes may have different meanings for different devices.

  1. SCSI architectural model

    The SCSI architectural model provides an abstract view of the way that SCSI devices communicate. It is intended to show how the different SCSI standards are inter related. The main concepts and terminology of the SCSI architectural model are Only the externally observable behavior is defined in SCSI standards. The relationship between SCSI devices is described by a client server service delivery model. The client is called a SCSI initiator and the server is called a SCSI target . A SCSI domain consists of at least one SCSI device , at least one SCSI target and at least one SCSI initiator interconnected by a service delivery subsystem . A SCSI device has one or more SCSI ports , and a SCSI port may have an optional SCSI port identifier SCSI ID or PID . A SCSI device can have an optional SCSI device name which must be unique within the SCSI domain in which the SCSI device has SCSI ports. This is often called a World Wide Name . Note that the world may only consist of a very small number of SCSI devices. A SCSI target consists of one or more Logical Unit Number SCSI logical unit numbers ... of four addressable levels. There are three type of SCSI ports initiator ports, target ports and target initiator ports. A SCSI device may contain any combination of initiator ports, target ports and target initiator ports. SCSI distributed objects are considered to communicate in a three layer model The highest level of abstraction is the SCSI Application Layer SAL where an initiator and a target are considered to communicate using SCSI command s sent via the SCSI application protocol . The SCSI ... using a SCSI transport protocol . Examples of SCSI transport protocols are Fibre Channel , Serial Storage Architecture SSA and the Parallel SCSI SCSI Parallel Interface .
