368 AS/400e System Handbook
The 3570 brings a new dimension of functionality to tape storage because of its revolutionary
data recall performance allowing new applications to be enabled in addition to traditional tape
applications. This includes applications where:
• Fast access to data is required such as storage management, network serving, mixed
digital libraries, and image processing.
• High I/O-intensive operations with multi-user access is required.
• Automated backup and restore or automated archive storage and retrieval are
required.
In addition, the IBM 3570 offers connectivity to other systems through the support of storage
management offerings such as the IBM ADSTAR Distributed Storage Manager for AS/400
Version 3.1 (ADSM), IBM Backup Recovery and Media Services (BRMS), and third-party
products.
Note: ADSM was withdrawn from marketing on 31 December 1999. Tivoli Systems Inc., an
IBM company, now offers Tivoli Storage Manager Version 3.7 to replace the ADSM product
set. See Tivoli Storage Management Solutions at:

3570 Cxx Models
The 3570-Cxx is available in five models, which are shown in the following table.
The Cxx models can read/write both B-format and C-format cartridges. The drive data
transfer rate is 7 MB/sec (uncompressed) with up to 15 MB/sec (compressed) using C-format
cartridges. For B-format cartridges, the rates are 3.5 MB/sec and 10.5 MB/sec. The drive
burst data rate is 20 MB/sec. Automatic caching of data enables balancing system read/write
performance. Note that the actual throughput achieved is a function of many factors and can
vary.
3570 Bxx Models
The 3570-Bxx model is the first generation of 3570s. The 3570-Bxx is available in five
models, which are shown in the following table.
