LTFS – the Linear Tape File System – seemed like a great idea when it emerged but not many storage vendors seem to have made much of it. It puts a file system on top of a tape library and turns it ...

It's hard to tell which storage techs will stand the test of time, but looking back at some of yesterday's storage technologies can help.

Though some folks mistakenly view tape as an outdated technology -- thanks in no small part to the fact that disk companies keep predicting its demise -- there's no denying its importance at the table of backup products. A recent Enterprise Strategy Group report indicates that 56% of organizations are still using tape. Perhaps not surprisingly, the larger the overall IT environment, the more likely that organization is to embrace tape as part of its data management strategy. There are two main reasons for this: The existence of more data heightens the importance of finding ways to store the data efficiently and, as an organization grows, it has a greater responsibility to store data for longer periods of time.
As a result, when looking at the Opex and Capex numbers, not to mention the ease of long-term data retention, tape moves to the forefront of the data management platform. When the LTO Consortium announced the release of LTO-7 as part of the Linear Tape File System in fall 2015, it reinforced the notion that tape technology is continuing to move forward. This three-part guide will take a closer look at what's out there and what's coming in terms of tape backup and tape libraries. It will also explain why archiving does not need to be complicated or expensive. In fact, when done correctly, it will actually save organizations money while meeting archival needs.Continue Reading

No, the tape storage system isn't dead yet. This Drill Down explores how it lives on, mainly for archiving and with a boost from new technologies such as LTO-7 and Linear Tape File System, or LTFS.
The seventh-generation LTO specification released in 2015 more than doubled the maximum compressed capacity to 15 TB and increased the data transfer rate to 750 MBps. LTO-7 also improved the bit error rate to a significant degree. The LTO Consortium already has LTO-8, LTO-9 and LTO-10 on its roadmap, each with significant capacity and performance improvements. For instance, draft specs for LTO-8 call for 32 TB of compressed capacity and sustained data transfer rates of up to 1,180 MBps.
These tape storage system advances become more important as speedier technology such as solid-state drives raise users' storage performance expectations. The performance and capacity gains also come as tape faces increased competition from the cloud for archiving. While cloud providers can store data cheaply, it can take a long time to get data in and out of the cloud.
LTFS creates partitions on tape and stores catalog information about files written to that tape. That makes it much easier to find and access files on a tape storage system than was possible before LTFS. Also known as tape NAS, it has been hailed as a tape's savior. While it hasn't caught on wildly, it is used by industries such as media and entertainment that make frequent use of archived tapes.Continue Reading
