IBM researchers demonstrate magnetic tape storage density forty times B

With the newly developed technologies and tape cartridge in the future, an LTO format holds up to 35 terabytes of uncompressed data. This corresponds approximately to the 44-times the capacity of today’s LTO tapes of the fourth generation. The researchers believe not, however, that the possibilities are exhausted with it. "This demonstration is an important step towards the development of tape storage with a recording density of 100 billion bits per square inch," said Evangelos Eleftheriou, head of the storage technology research at IBM Research in Zurich.

"The tape technology to their cost advantage over disk storage and flash can continue to maintain and continue to allow affordable and robust data protection," said Cindy Grossman, vice president for IBM’s tape storage and archiving systems. This is particularly true for the remaining uses of magnetic tape, such as securing large amounts of data that would not regularly required, such as data and video archives, backup files and backup copies as part of disaster management or legal compliance.

In terms of cost per gigabyte tapes are in long-term storage of data, IBM said in a fifth to one tenth of current hard disk storage. Another advantage is that unlike continually rotating disk tape cartridges require no power when not accessed.

IBM researchers demonstrate magnetic tape storage density forty times A

In a demonstration, they reached 29.5 billion bits per square inch. Based on these tape storage systems with 35 terabytes per tape cartridge will be developed. Application is the long-term storage of large amounts of data.

Researchers at IBM Research in Zurich have written in collaboration with Fujifilm on an advanced test tape 29.5 gigabits per square inch. That is almost forty times as much as is achieved with current products. They wanted to occupy so that one of the oldest technologies for data storage offers the potential for further capacity increases and not long had its days.

To achieve the record-storage density, improved the IBM researchers together with Fuji for three years the doubly coated on barium ferrite magnetic particles of the Japanese-based company. Due to the precise positioning of the read / write heads can also 25 times more data tracks on the same 0.5-inch-wide tape can be accommodated. A more precise identification of the individual bits also allows the 50-percent increase in linear recording density. In addition, a novel friction read / write head is necessary.

Published TPC benchmark for power consumption of servers

TPC-Energy is available as a 55-page PDF document. It complements existing test methods to calculations of the efficiency. It is regarded as one of the three most important purchase factors.

The Transaction Processing Performance Council (TPC) has published a test method for power consumption of servers. TPC-Energy, measures how efficiently working server systems – how much they can do with a certain amount of energy. The benchmark procedure is available as a 55-page PDF document.

TPC has developed a number of recognized benchmarks server and published on its website charts tested systems. TPC-C TPC-E and his successor, for example examine the database performance, TPC-H performance with data warehouse applications. TPC-energy supplements this process by a few additional calculations to determine a value for watts per performance, tells the benchmark group.

The TPC is actually composed of 24 members, including all the major manufacturers of servers. Two members, however, are just a merged Oracle and Sun Microsystems.

The Head of Department responsible for the efficiency test TPC Committee Mike Nikolaiev says: “In recent years the number of server installations has increased exponentially throughout the world. The energy for the operation and the cooling is now one of the three most important factors in the server purchase. Buyers need an objective method to set the price, performance and energy consumption in relation to their needs and to sort by.

IBM works with EU to more reliable chips

The Diamond Consortium is to enhance a finding errors in the chip development. This should reduce the development costs long term. The EU provides subsidies.

IBM wants to get together, according to a press release with companies and universities in the European Union in order to improve the reliability and efficiency of semiconductor chips. The EU-funded organization called Diamond Consortium. The project has a timeframe of three years.

An objective of the Diamond project is to work together to find a more systematic approach to search for chip defects. Currently, 70 percent of the work in the development of a chip inserted into the debugging, says IBM. The majority of them will invest in order to find the error and correct it.

“Soft errors” are particularly difficult to find and predict. This type of transient malfunction creeps by external factors. An example of one such factor is the cosmic radiation. Their effects are greater, the smaller and denser, the chips are mounted.

From the new technology is expected to IBM engineers, such soft errors can be predicted better. These are special use improved detection methods, which could reduce the time to eliminate these types of errors by 23 percent.

Error found in chips and correct costs to the producers in this year 34.5 million U.S. dollars (25.4 million), expects IBM. The Diamond Consortium is hoping to reduce the time for debugging by half. On the cost side, could theoretically bring a savings of 17.25 million U.S. dollars (12.72 million euros).

Besides IBM take on Diamond Project Ericsson, part of the Tallinn University of Technology, the Swedish Linkoping University, the University of Bremen, the Technical University in Graz, TransEDA system from Hungary and TestonicaLab from Estonia.
