At the beginning of the year I blogged about the updates to the LTFS EE V18.104.22.168 Redbooks pub. that included support for Elastic Storage 4.1. IBM has announced the IBM Spectrum StorageTM Family. An important part of the announcement is that LTFS provides the functionality for IBM Storage Archive™ and IBM Storage Scale™ is based upon IBM General Parallel File System™ or GPFS, also formerly known as code name Elastic Storage. The LTFS EE V22.214.171.124 changes were key to building a stronger connection between Spectrum Archive and Spectrum Scale which opens up new opportunities for tape as tier in Software Defined Environments.
IBM Spectrum Archive™ enables you to automatically move infrequently accessed data from disk to tape to lower costs while retaining ease of use and without the need for proprietary tape applications. The functionality of IBM Spectrum Archive is provided by IBM Linear Tape File System.
IBM Spectrum Scale™ is flash accelerated, industrial strength, highly scalable software defined storage that enables global shared access to data with extreme scalability and agility for cloud and analytics.
IBM Linear Tape File System Enterprise Edition V126.96.36.199 Installation and Configuration Guide Redbooks Publication published January 29. This edition is only two months after the final publication of the V188.8.131.52. Spectrum Archive Enterprise Edition (formerly LTFS EE) now supports Spectrum Scale and the new TS1150 tape drive. The TS1150 tape drive with JD/JZ cartridges (native capacity of 10 TB (.9 TiB)), 8 Gbps Fibre connection speed, and 360 MB/s native data rate will make your tape tier in the cloud faster and denser.
This revision reflects the addition, deletion, or modification of new and changed information described below.
