The TS1150 implements an enhanced SARS function that is known as client-centric SARS (ccSARS). This function improves the overall amount of information that is maintained, and the presentation means to the client with the automation system. 

The media SARS function for the drives includes the following actions: 

GLYPH<SM590000> Tape alerts are generated when media passes usage life, as determined by full-file passes, meters of tape that were processed, or the write pass count, and the total number of mounts (which was supported). 

GLYPH<SM590000> A media SARS summary is maintained in the cartridge memory in a manner where it can be rebuilt on tape if the SARS records on tape cannot be read and must be reinitialized. This cartridge memory copy is also readable on an earlier level TS1140 drive to preserve SARS information between logical format conversions. 

## 3.5.13 Encryption 

The TS1160 tape drives is encryption-capable. Like the previous models, you do not need to enable the drive specifically. 

Encryption support includes the following enhancements: 

GLYPH<SM590000> LME, AME, and SME (for TS7700). 

GLYPH<SM590000> T10 default method support. 

GLYPH<SM590000> Continued encrypted data key (EEDK) wrapped key support in LME and SME. 

GLYPH<SM590000> Enhanced protocol support for Internet Printing Protocol (IPP), which can be configured for security, and Java Platform, Enterprise Edition 2 historical mode (as used by IBM Spectrum Protect), T10 default method, Security Protocol IN (SPIN), and Security Protocol OUT (SPOUT). 

GLYPH<SM590000> Enhanced drive cryptographic upgrades to change the default authentication means from Secure Hash Algorithm-1 (SHA-1) to SHA-2 when you use IBM Security Key Lifecycle Manager. 

T10 standards-based encryption control on a logical block basis (not tied to format identifier) and writes encrypted data and clear data to the same tape cartridge. 

## 3.6 IBM TS1155 and TS1150 tape drive 

The IBM TS1155 tape drive (which is also referred to as the 3592 Model 55E, 55F , or 55G) is an enhanced fifth generation tape drive of the IBM 3592 tape family. The TS1155 tape drive provides higher levels of cartridge capacity than the TS1150 Model E08 (EH8). It is designed to provide an increased capacity of 50% on JD media types compared with its predecessors. 

The primary difference of the TS1155 (55E, 55F, and 55G) from the base TS1150 drive (E08, EH8) is that the capacity is increased 50% on JD media types. In addition, for the TS1155, model 55E Ethernet host attachment (RoCE v2) ports have been added. 

The TS1155 model 55F and 55G tape drive has a dual-port 8-Gbps Fibre Channel interface for Fibre Channel attachment to host systems, or a switched fabric environment. 

The TS155 model 55E tape drive has a dual ported 10 Gb Ethernet port for host attachment that is optimized for cloud-based and large, open-compute environments.
