## 3.6.5 Emulation 

This topic describes emulation mode and drive emulation regarding the TS1155 and TS1150 tape drive. 

## Emulation mode 

The TS1155 and TS1150 does not support any emulation modes. Because the drive cannot write the TS1120 or J1A logical format, it cannot fully emulate all format behaviors of a previous model 3592 drive. 

## Drive emulation 

The TS1155 and the TS1150 tape drive do not support emulation. The TS1155 can read and write in J5A and J5 format with compatible IBM 3592 tape cartridges. The TS1150 can read and write in J5 and J4 format with compatible IBM 3592 tape cartridges. 

The TS1155 tape drive can reformat any compatible J5 tape when it is writing from BOT and the TS1150 can reformat any J4 format tape. Table 3-14 lists the available modes for TS1150 and TS155.

## 3.6.6 IBM Spectrum Archive and LTFS support 

Tape as a storage medium has many benefits: It is reliable, portable, low-cost, low-power, and high-capacity. However, tape is not easy to use because it has no standard format and data often cannot be used without first copying it to a disk. 

IBM Spectrum Archive enables direct, intuitive, and graphical access to data stored in IBM tape drives and libraries by incorporating the LTFS format standard for reading, writing, and exchanging descriptive metadata on formatted tape cartridges. IBM Spectrum Archive eliminates the need for additional tape management and software to access data. IBM Spectrum Archive offers three software solutions for managing your digital files with the LTFS format: Single Drive Edition, Library Edition, and Enterprise Edition. 

For more information about IBM Spectrum Archive and LTFS, see IBM Spectrum Archive Single Drive Edition and Library Edition: Installation and Configuration Guide , SG24-8090. 

The TS1155 and TS1150 provides LTFS support with the following features: 

GLYPH<SM590000> Ability to configure up to four partitions 

GLYPH<SM590000> Wrap-wise and longitudinal-wise partitioning 

GLYPH<SM590000> Supported on all non-WORM TS1150 formats (JC, JK, and JB formats) 

GLYPH<SM590000> Format command support 

GLYPH<SM590000> Each partition can use a separate encryption method, or none
