As LTO-8 drives and media are increasingly deployed and widely available, the value proposition of LTO-8 is being confirmed by customers and it’s a pretty impressive story.
In the case of a major high-performance computing (HPC) customer who had been using LTO-6 previously for their archive, the jump to LTO-8 has done wonders for their available capacity. With approximately 7,000 slots in their library, fully loaded with LTO-6 media at 2.5TB each yielded a total native storage capacity of 17.5 PB. Migrating to LTO-8 drives and eventually converting those slots to LTO-8 media at 12.0 TB gives them up to a massive 84 PBs, almost a 5X increase. That’s lots of room to scale as needed!
Performance also gets a big boost as LTO-6 drives are rated at 160 MB per second transfer rate compared to LTO-8 drives at 360 MB per second. This means fewer drives are required to meet the same performance objectives. As a result, TCO also gets a major boost as fewer drives, fewer pieces of media and no additional floor space or library frames are required to manage the same amount of data.
