Internal Magnetic Media 341Internal Magnetic MediaAlternate IPLThroughout this book and in theiSeries and AS400e System Builder, SG24-2155, the termAlternate IPL (ALT-IPL) is used to describe both Alternate IPL devices and AlternateInstallation Devices. It is important to understand the differences.#4483#4583#6383#648316GB QIC V4R1 LZ1 QIC-5010 1.5 M/sec 32 GBQIC-4DC 3 760 K/sec 8 GBQIC4GB 380 K/sec 8 GBQIC2DC 3 600 K/sec 5 GBQIC2GB 300 K/sec 5 GB#4486#4586#6386#648625GB QIC V4R1 LZ1 MLR3 2 M/sec 50 GBQIC-5010 1.5 M/sec 32 GBQIC-4DC 3 760 K/sec 8 GBQIC4GB 380 K/sec 8 GBQIC2DC 3 600 K/sec 5 GBQIC2GB 300 K/sec 5 GB#4487#458750GB QIC V5R1 LZ1 SLR100 5 M/sec 100 GBMLR3 2 M/sec 50 GB#6390#6490#12617GB 8mm V3R0M5 LZ1 FMT7GB 500 k/sec 14 GBFMT5GB 500 k/sec 10 GBFMT2GB 240 k/sec 2.3 GB native (nocompression inthe drive)1. I ndicates whether the attachment IOP supports Hardware Data Compression (HDC) and whether the tapesubsystem controller supports a compaction algorithm, either Improved Data Recording Capability (IDRC) orLempel 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 volumeof data.3. QIC2DC and QIC4DC are compressed formats. Cartridge capacity is data dependent. The capacities shownare typical.4. Effective Data Transfer Rate typically doubles when data is compressed or compacted.Feature DescriptionOS/400Version(minimum)CompactionAlgorithm 1SupportedFormatsData TransferRate(Native) 4Max Capacity(Compressed) 2
