Linear Tape Open (LTO) Ultrium is a high-capacity, single-reel tape storage solution developed and continually enhanced by Hewlett Packard Enterprise, IBM and Quantum and promoted by the LTO Program. It’s a powerful, scalable and adaptable tape format that helps address the growing demands of data protection. It’s also an open format, licensed by some of the most prominent names in the storage industry to ensure a broad range of compatible tape drives and cartridges.
The Linear Tape File System (LTFS) makes viewing and accessing tape files easier than ever before. LTFS works in conjunction with LTO tape technology for ease of use and portability for open systems tape storage. With LTFS, one partition holds the content and the other holds the content’s index, so the tape can be self-describing to improve archive management. With the operating system’s graphical file manager and directory tree, utilizing data on an LTO Ultrium tape cartridge is as easy as dragging and dropping the file.
LTO Generation 8 delivers the latest in tape technology with more than 30TB* of compressed capacity and up to 750 MB/s* data transfer rates. With continued support of partitioning to enable functions like LTFS making tape easy to manage, nothing beats LTO-8 technology for all of your storage needs.
The LTO Program is introducing a new capability with LTO-8 drives: The ability of the LTO-8 drive to write 9 TB on a brand new LTO-7 cartridge instead of 6 TB as specified by the LTO-7 format. Such a cartridge is called an LTO-7 cartridge initialized as Type M media. The TPCs have agreed upon designating these LTO-7 Type M media by using an automation barcode label ending with the last 2 characters “M8”. A normal LTO-7 cartridge is referred to as LTO-7 Type A, has a capacity of 6 TB, and is indicated with an automation barcode label ending in “L7”. An LTO-8 cartridge is indicated with an automation barcode label ending in “L8”.
Only new, unused LTO-7 cartridges may be initialized as LTO-7 Type M media. Once a cartridge is initialized as Type M, it may not be changed back to a 6TB LTO-7 cartridge. Also, an LTO-7 cartridge initialized as LTO-7 Type M media can only be written and read in an LTO-8 drive; LTO-7 drives are not capable of reading LTO-7 Type M media.
