Alternate IPL
Throughout this book and in the iSeries and AS400e System Builder , SG24-2155, the term
Alternate IPL (ALT-IPL) is used to describe both Alternate IPL devices and Alternate
Installation Devices. It is important to understand the differences.

1. Indicates whether the attachment IOP supports Hardware Data Compression (HDC) and whether the tape
subsystem controller supports a compaction algorithm, either Improved Data Recording Capability (IDRC) or
Lempel Ziv 1 (LZ1). These algorithms enable more data to be written to tape up to the maximum shown.
2. Compressed values assume a 2:1 compression. Actual results may vary depending on the type and volume
of data.
3. QIC2DC and QIC4DC are compressed formats. Cartridge capacity is data dependent. The capacities shown
are typical.
4. Effective Data Transfer Rate typically doubles when data is compressed or compacted.
