Linear Tape Open or better known as (LTO) Ultrium is a high-capacity, single-reel tape storage created and frequently improved by HPE, IBM and Quantum. LTO tape is a powerful yet scalable tape format that helps address the growing demands of data protection.
PROVIDING GROWTH FOR GENERATIONS.
Originally introduced at the turn of the new millennium, LTO technology is currently in its 8th generation out of a proposed twelve generations. LTO-8 supports storage capacity of up to 30 TB compressed, twice that of the previous generation LTO-7, and data transfer rates of up to 750MB/second. New generations of LTO storage have been launched consistently with higher capacity and transfer rates along with new features to further protect enterprise data. Furthermore, LTO storage is designed for backward compatibility meaning it can write back one generation and read back two generations of tape. Currently, LTO-8 Ultrium drives are able to read and write LTO -7 and LTO-8 media, ensuring the data storage investment.
LTO technology highlights a write-once, read-many (WORM) ability to make certain that your data isn’t overwritten and supports compliance regulations. The LTO WORM operation is designed to give users a very cost-effective means of storing data in a non-rewriteable format. With the increasing importance of regulatory compliance — including the Sarbanes-Oxley Act of 2002, the Health Insurance Portability and Accountability Act of 1996 (HIPAA), and SEC Rule 17-a-4(f) — there is a need for a cost-effective storage solution that can ensure security of corporate data in an permanent format. LTO WORM contains algorithms using the Cartridge Memory (CM), in combination with low level encoding that is mastered on the tape media to prevent tampering.
LTO technology features robust encryption capabilities to heighten security and privacy during storage and transport of tape cartridges. Sadly, it seems like a common occurrence now when a company suffers a breach in security and endangers confidential or private information. Fortunately, recent generation LTO tape drives include one of the strongest encryption capabilities available in the industry to help safeguard the most vulnerable data stored on tape cartridges. LTO tape encryption is specific to all LTO generations since generation 4 (LTO-4). It features a 256-symmetric key AES-GCM algorithm that is implemented at the drive level. This facilitates compression before encryption to maximize tape capacities and deliver high performance during backup. With a rising number of laws and regulations and financial penalties, a security breach can be damaging for corporations. Data managers are called upon to develop effective security for sensitive data and are turning to tape encryption.
More modern generations of LTO technology include a partitioning feature, which help to enhance file control and space management with the Linear Tape File System (LTFS).
Beginning with the 5th generation (LTO-5), LTO technology specifications consist of a partitioning feature that allows for a new standard in ease-of-use and portability.
Partitioning allows for a section of the tape to be set aside for indexing, which tells the drive exactly where in the tape a file is stored. The second partition holds the actual file. With LTFS, the indexing information is first read by the drive and presented in a simple, easy-to-use format that allows for “drag and drop” capabilities, similar to a thumb drive.
