Performance Data | Tape Speed | | Read/Write | 79 IPS (2 m/s) | Search/Rewind | 315 IPS (greater than 8 m/s) | Tape Load and Initialize to Ready | 18 s | Search Time | 41 s (average 1st search) | Maximum Rewind Time | 90 s | Interfaces (per Drive) | 1 ESCON, 1 Ultra-SCSI or2 Fibre Channel (SC optical) | Compression | Enhanced LZ-1, 4:1 Ratio | Individual compression achieved is a function of many variables, including the data characteristics. For example, scientific data usually compresses less than general business data. As a practical guide, mainframe (MVS/ESCON) compression rates are typically 4:1, while client server operating systems (UNIX/NT on SCSI or Fibre) usually achieve in the 2:1 to 2.5:1 range. In all instances, slightly lower or significantly higher numbers may be achieved. | Data Buffer Size | 8 MB | Data Transfer Rates | | Head-to-Tape | 10 MB/s (uncompressed) | Interface (burst rate) | 100 MB/s Fibre (256 KB) | Maximum Block Size | 256 kb | Supported Features | Tape Alert Emulation Modes – Native, 3490E, 3590 FCP-2 (FC Tape) |
