Port multiplier

A Serial ATA port multiplier is a device that allows multiple SATA devices to be connected to a single SATA host port. Many common controllers do not support this feature, as it is not a requirement for a SATA controller.

Benefits

Port multipliers have the following potential benefits:

Port multiplication

A Serial ATA port multiplier is a unidirectional splitting device. While it allows one equipped port to connect up to 15 disks, the bandwidth available is limited to the bandwidth of the link to the controller, as of 2012 1.5, 3, or 6 Gbit/s. While the controller is aware that there are multiple drives connected, the service is transparent to the disks attached. Because they believe they are communicating directly with the controller, any drive that holds to the SATA standard can be connected to a port multiplier. There are two ways port multipliers can be driven:

Serial ATA

Serial ATA (SATA, abbreviated from Serial AT Attachment) is a computer bus interface that connects host bus adapters to mass storage devices such as hard disk drives, optical drives, and solid-state drives. Serial ATA succeeded the older Parallel ATA (PATA) standard, offering several advantages over the older interface: reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing protocol.

SATA host adapters and devices communicate via a high-speed serial cable over two pairs of conductors. In contrast, parallel ATA (the redesignation for the legacy ATA specifications) used a 16-bit wide data bus with many additional support and control signals, all operating at much lower frequency. To ensure backward compatibility with legacy ATA software and applications, SATA uses the same basic ATA and ATAPI command sets as legacy ATA devices.

SATA has replaced parallel ATA in consumer desktop and laptop computers, and has largely replaced PATA in new embedded applications. SATA's market share in the desktop PC market was 99% in 2008. PATA remains widely used in industrial and embedded applications that use CompactFlash (CF) storage, which is designed around the legacy PATA standard, even though the new CFast standard is based on SATA.

Sata (food)

Sata (Chinese: 沙爹) is a traditional dish from the Malaysian state of Terengganu, consisting of spiced fish meat wrapped in banana leaves and cooked on a grill.

It is a type of Malaysian fish cake, or otak-otak. The main ingredients of sata are grated coconut, sardines, ginger, onions and chili peppers.

Sata is not to be confused with satay, another dish popular in Malaysia.

Okko

Okko is a comic book published in a series of mini-series, or cycles. Originally published in France by Delcourt, Archaia Studios Press started reprinting the series in English in 2006. This series is intended for Mature Readers; it contains adult content, graphic violence, and nudity.

Written and illustrated by Hub with colors done by Hub (Humbert Chabuel) and Stephan Pecayo. The English translation was provided by Edward Gauvin.

Premise

The action of the first cycle of Okko takes place at the far end of the known lands of the Empire of Pajan. Pajan itself is a vast and diversified island, surrounded by a multitude of archipelagoes. Its name is derived from that of its Imperial Family. Though the Pajans have reigned for a millennium, in the last few decades three major families—the Ataku, the Boshimon, and the Yommo—have called into question their legitimacy and now refuse to cease their battles against the Imperial Family. These power struggles have destabilized the Empire, and famine and catastrophes follow one another. This period of chaos is commonly called the Era of Asagiri (the Time of Mists).

Hub (comics)

Hub is a fictional mutant character in the Marvel Comics Universe. Her first appearance was in Excalibur vol. 3 #2.

Fictional character biography

Little is known about Hub before she made her appearance on the desolate island of Genosha. She was one of the few survivors after Cassandra Nova programmed her Wild Sentinels to decimate the island, killing over 16 million mutants.

Somehow she found other survivors and allied herself with Unus the Untouchable and his gang. She was a very valuable asset on the island since all forms of transport were eradicated or made useless by the resulting electro-magnetic damage. Inside of the gang, she became close friends with Hack and the two of them began to doubt if Unus' exclusive, clique-like strategy was the best way.

When a mentally ill Scarlet Witch removed the mutant gene from over 90% of the mutant population, Hub was one of the many who lost her powers. However, Quicksilver—as an act of penance for his part in the worldwide depowering—stole some Terrigen crystals from the Inhumans in an attempt to repower some mutants. He started his mass efforts in Genosha and effectively restored the abilities of many on the island including Wicked, Freakshow, Purge, and Callisto. But in a cruel twist of fate, their abilities were amplified beyond control and quickly faded. Hub's fate since that time is unknown.
