IBM Linear Tape File System (LTFS) delivers the functions of IBM Spectrum Archive™, a member of the IBM Spectrum Storage™ family, and provides an easy to use GUI that enables you to automatically move infrequently accessed data from disk to tape without the need for proprietary tape applications. Only IBM offers four options for managing your digital files with LTFS: Single Drive Edition, Library Edition, Storage Manager and Enterprise Edition. Implementing LTFS Enterprise Edition allows you to replace disk with tape for tiered storage – and lower your storage TCO by over 50 percent.
