LTO标准最初由惠普、IBM、Seagate三家存储厂商合作开发而成,三家厂商是LTO开放性标准的制订者也是主要的推动者。而惠普Ultrium产品是LTO格式的代表。与其它的磁带格式相比,LTO Ultrium格式具有高可靠性、大容量、高性能等特点,能够单独操作,也可在自动操作环境中使用,适合于备份、存储和归档应用。更为关键的是,LTO Ultrium是开放的技术标准,这正与惠普存储所倡导的开放性相吻合。早在1999年惠普就制定了清晰的LTO Ultrium发展战略。该发展战略将Ultrium规划出了四代产品,从第一代的100Gb,12～20Mb/s到第四代的800Gb,80～160Mb/s,容量和传输速度成倍增加。此外,从Ultrium1到Ultrium 4,产品设计思路以及技术提升手段也在不断完善。普通磁带库的升级采用增加磁道密度和提高磁带转速的方式,从Ultrium 1到Ultrium 2还采用这种形式,然而,磁带转速的提高虽然满足了磁带的高度写入、读取但却不可避免的增加了卡带、断带的机率,并
The LTO standard was originally developed by three storage vendors Hewlett-Packard, IBM, and Seagate. The three vendors are the makers and main promoters of LTO’s open standards. The HP Ultrium product is the representative of the LTO format. Compared to other tape formats, LTO Ultrium format features high reliability, high capacity, high performance, and can be used alone or in an automated environment for backup, storage and archiving applications. More crucially, LTO Ultrium is an open technology standard that is in line with the openness advocated by HP Storage. As early as 1999, Hewlett-Packard developed a clear LTO Ultrium development strategy. The development strategy will Ultrium out of four generations of products, from the first generation of 100Gb, 12 ~ 20Mb / s to the fourth generation of 800Gb, 80 ~ 160Mb / s, double the capacity and transmission speed. In addition, Ultrium1 to Ultrium 4, product design ideas and technology improvements are also constantly improving. Ordinary tape library upgrades take the form of increased track densities and higher tape speeds from Ultrium 1 to Ultrium 2, however, while tape speed increases to meet the tape’s high write, read but inevitable Increase the cassette, the probability of broken, and
