Organizations that need long-term retention of large amounts of data often rely on tape storage due to its endurance, low energy consumption, low total cost of ownership, and impressive sustainability. But when it comes to retrieving random files, it’s widely recognized that tape can’t match the speed of hard disk drives or flash storage.
But there’s some good news on that front. An innovation in tape technology called Recommended Access Ordering (RAO) has recently improved random file retrieval times for LTO 9 drives significantly. RAO has been available in IBM enterprise tape products for years, but only recently has this capability been added to LTO 9 full-high tape drives.
• Native data rate of up to 400 MB/s• Native data physical capacity of 18000GB• The data compression keeps the ratio to 2.5:1• Support for 8Gb FC and 12Gb SAS connectivity• SkipSync Function to provide small file backhitchless flush capability • Cache buffer: 1024MB
LTO 9 L9 media RAO Performance
The Locate and Locate+Read performance of the IBM LTO 9 tape media on the IBM LTO 9 tape drive is described by the following set of charts that show how the drive behaves when locating or locating+reading data in the access order determined by RAO and Sorted by record number using differing numbers of 200MiB UDSes (4, 8, 16, 32, 128, 512 and 2000).
LTO 9 L9 media RAO Locate+Read Performance Range
The range of the Locate+Read performance of the IBM LTO 9 tape media on the IBM LTO 9 tape drive is described by the following set of charts that show how the drive behaves when locating+reading data in the access order determined by RAO and Sorted by record number using differing numbers of 200MiB UDSes (4, 8, 16, 32, 128, 512 and 2000).
Since the introduction of the first LTO tape drive, every successive generation has incorporated new features and performance improvements. Now the IBM LTO 9 tape drives in conjunction with the new LTO Gen 9 media represent an efficient solution for today’s growing storage demands.
IBM LTO 9 tape drives are already a smart storage solution for businesses requiring backup and archival storage of their data. With the addition of RAO, customers now have the same benefits, along with increased speed.
