IBM 3490 Tape System FamilyThe IBM 3490 is a family of Magnetic Tape Subsystems designed to provide significant tape subsystem performance and cartridge capacity improvements.

The3490-A01is a 18-track, 1 Control Unit component for an IBM 3490 tape subsystem. The Model A01 supports the 3490 Models B02 and B04 Tape Drive Units. The Model A01 can be field upgraded to either a Model A02 or Model A10, providing granularity from a minimum 1x2 (A01 x B02-18 track) configuration to a maximum 2x8 (A10 x four B20-36 track) configuration. Included as standard in the Model A01 is Improved Data Recording Capability (IDRC) and a 2Mb buffer. Components are serviced from the rear to minimize operational interference.

The3490-A02is an 18-track, 2 Control Unit component for an IBM 3490 tape subsystem. The IBM 3490 Model A02 supports the 3490 Model B02 and B04 18-track Tape Drive Units. The subsystem will occupy approximately 50 percent less floor space than a comparable 3480 configuration by incorporating up to two control unit functions in one box. The Model A02 can be field upgraded to a Model A20, providing granularity from a minimum 2x2 (A02 x B02-18 track) configuration to a maximum 2x16 (A20 x four B40-36 track) configuration. Included as standard in the Model A02 is Improved Data Recording Capability (IDRC), dual communications capability, and a 2 Mb buffer. Components in the control units are serviced from the rear to minimize operational interference.

The3490-A10is a 36-track, 1 Control Unit component of an IBM 3490 tape subsystem. The IBM 3490 Enhanced Capability (3490E) Model A10 Control Unit supports the Models B20 and B40 Tape Drive Units. The A10 can be field upgraded to the A20, providing granularity from a minimum 1x2 (A10 x B20) configuration to a maximum 2x16 (A20 x Four B40s) configuration. Included as standard are: Improved Data Recording Capability, an 8 Mb buffer and improved utilization of ES Connection* (ESCON*) adapters providing new possibilities in performance, connectivity, and remote tape operations.

The3490-A20is a 36-track, 2 Control Unit component for an IBM 3490 tape subsystem. The IBM 3490 Enhanced Capability (3490E) Model A20 Control Unit supports the Models B20 and B40 Tape Drive Units. The A20 provides granularity from a minimum 2x2 (A20 x B20) configuration to a maximum 2x16 (A20 x Four B40s) configuration. Standard features include: Improved Data Recording Capability, an 8 Mb buffer, Dual Communications Capability, and improved utilization of ES Connection* (ESCON*) adapters providing new possibilities in performance, connectivity, and remote tape operations.

Table 1. Characteristics of IBM 3490/3490E Tape DevicesThe IBM® 3490E Models A01/A02 and A10/A20 do not include channel attachment as standard equipment. Channel adapter type and quantity must be specified at initial order.This function uses an 8MB buffer and an increased speed compactor. An instantaneous data rate of up to 9MB/sec is provided on ESCON channels.
