By using the built-in data-compression capability of the tape drive, greater data rates than the  native data transfer rate can be achieved. However, the actual throughput is a function of  many components, such as the host system processor, disk data rate, block size, data  compression ratio, SCSI bus capabilities, and system or application software. For more information about LTO-8 tape drives, see “IBM LTO Ultrium 8 tape drives” on  page 80. The TS3100 supports Path Failover feature. Path Failover is a combination of two previous  features: Control Path Failover and Data Path Failover.  The device driver Path Failover support configures multiple physical control paths to the  same logical library within the device driver and provides automatic failover to an alternate  control path when a permanent error occurs on one path. This function is not apparent to the  running application. The IBM TS3100 tape library supports data encryption with LTO-8 tape drives. The following  modes of encryption are supported: For LTO Ultrium 8, the Transparent LTO encryption feature is required for enabling  encryption. The IBM Security Key Lifecycle Manager is required for enabling System  Managed and Library Managed encryption. The installation of an Ultrium 8 tape drive with encryption might require code updates for IBM  Power Systems, and supported open systems devices drivers or storage management  software. An update of the open systems device drivers can be obtained from the Fix Central  download portal at this website: http://www.ibm.com/support/fixcentral For more information about Encryption, see 2.2, “Tape encryption overview” on page 68. The TS3100 supports IBM Spectrum Archive Library Edition (LE) and the associated Linear  Tape File System (LTFS). IBM Spectrum Archive provides software to manage, monitor, archive, and restore files. LTFS  is the first file system that works with the multiple partitioning that is available on Ultrium 8, 7,  6, and 5 tape drives. This feature brings a new level of use and portability to open systems  tape storage.  This storage software helps to reduce complexity in data management and access time  through the enablement of a self-describing tape that includes a simple file index. LTFS  allows files and directories to be shown on the desktop, directory listing, and to drag-and-drop  file to and from tape. It also supports data exchange and has a simple one-time installation. 246  IBM Tape Library Guide for Open Systems 9.3.4 IBM Spectrum Archive and LTFS 9.3.3 Encryption 9.3.2 Path failover GLYPH<SM590000> System Managed (available for AIX, Linux, Solaris, and Microsoft Windows) GLYPH<SM590000> Library Managed (available for OS/400, i5/OS, AIX, Linux, HP-UX, Solaris, and Microsoft  Windows) GLYPH<SM590000> Application Managed (IBM Spectrum Protect)
