International Blinking Pattern Interpretation
The International Blinking Pattern Interpretation (IBPI) is an internal computer hardware standard. It defines two items: # How SGPIO is interpreted into states for drives or slots on a backplane. # How light emitting diodes (LEDs) on a backplane should represent these states. IBPI was defined by the SFF-8489 specification of the Small Form Factor Special Interest Group in 2011. SGPIO has been adopted across the storage industry, and has in large replaced proprietary protocols such as SCSI Enclosure Services (SES) and SAF-TE. ''States'' for drives or slots can be, for example, ''empty'', ''failed'', ''rebuilding'', etc. The ''state'' of a drive or slot is determined by the host bus adapter, and is typically transmitted to the backplane through SGPIO-signals on a cable. Typical system architecture In a typical system architecture, the host bus adapter (HBA) connects to a backplane through a 4× iPass cable. The SGPIO-signals run inside this cable. The backplane may then optionall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SGPIO
Serial general purpose input/output (SGPIO) is a four-signal (or four-wire) bus used between a host bus adapter (HBA) and a backplane. Of the four signals, three are driven by the HBA and one by the backplane. Typically, the HBA is a storage controller located inside a server, desktop, rack or workstation computer that interfaces with hard disk drives or solid state drives to store and retrieve data. It is considered an extension of the general-purpose input/output (GPIO) concept. The SGPIO specification is maintained by the Small Form Factor Committee in the SFF-8485 standard. The International Blinking Pattern Interpretation indicates how SGPIO signals are interpreted into blinking light-emitting diodes (LEDs) on disk arrays and storage back-planes. History SGPIO was developed as an engineering collaboration between American Megatrends Inc, at the time makers of back-planes, and LSI-Logic in 2004.

Computer Buses
In computer architecture, a bus (shortened form of the Latin '' omnibus'', and historically also called data highway or databus) is a communication system that transfers data between components inside a computer, or between computers. This expression covers all related hardware components (wire, optical fiber, etc.) and software, including communication protocols. Early computer buses were parallel electrical wires with multiple hardware connections, but the term is now used for any physical arrangement that provides the same logical function as a parallel electrical busbar. Modern computer buses can use both parallel and bit serial connections, and can be wired in either a multidrop (electrical parallel) or daisy chain topology, or connected by switched hubs, as in the case of Universal Serial Bus (USB). Background and nomenclature Computer systems generally consist of three main parts: * The central processing unit (CPU) that processes data, * The memory that holds ...

Sandisk
SanDisk is a brand for flash memory products, including memory cards and readers, USB flash drives, solid-state drives, and digital audio players, manufactured and marketed by Western Digital. The original company, SanDisk Corporation was acquired by Western Digital in 2016. Western Digital was the fourth-largest manufacturer of flash memory having declined from third-largest in 2014. History SanDisk was founded in 1988 by Eli Harari, Sanjay Mehrotra, and Jack Yuan, incorporated at the time as SunDisk. SanDisk co-founder Eli Harari developed the Floating Gate EEPROM which proved the practicality, reliability and endurance of semiconductor-based data storage. In 1991 SanDisk produced the first flash-based solid-state drive (SSD) in a 2.5-inch hard disk drive form factor for IBM with a 20 MB capacity priced at about $1,000. In 1992, SanDisk (then SunDisk) introduced FlashDisk, a series of memory cards made for the PCMCIA or PC card form factor, so they could be inserted ...

Molex
Molex LLC is a manufacturer of electronic, electrical, and fiber optic connectivity systems. Molex offers over 100,000 products across a variety of industries, including data communications, medical, industrial, automotive and consumer electronics. They are notable for pioneering the Molex connector, which has seen universal adoption in personal computing. The company is considered the second largest electronic connector company in the world. History Molex was established in 1938 by Frederick Krehbiel. The company began by making flowerpots out of an industrial byproduct plastic called Molex. Krehbiel developed this material by combining asbestos tailings, coal tar pitch, and limestone. Aside from flower pots, Molex also sold salt shakers before it expanded into electrical connectors and sensors. Later they made connectors for General Electric General Electric Company (GE) is an American multinational conglomerate founded in 1892, and incorporated in New York state and h ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film ''Fantasia'', which allowed Hewlett and Packard to formally es ...
