iSeries Handbook
This table indicates the types of sessions that count toward the maximum number of active
sessions.
The iSeries server supports a family of displays and emulation adapters that are known as
the 5250. The supported data stream is, therefore, known as a 5250 data stream. Throughput
considerations are discussed here.
5250 Express Data Stream
The #2720, #2722, #2746, #4746, and #6180 twinax workstation adapter cards have three
major features that can increase throughput:
•
2X Mode: 2 Mbps versus 1 Mbps throughput of the #6050 workstation controller.
•
Optimized Mode: The block transfer of data is improved to almost double the
throughput to or from the attached device.
•
Dual Mode: Means that two ports are polled simultaneously on the #2722, #2746,
#4746 and #6180 workstation controllers. On older controllers (such as the #6050
workstation controller), only one port out of eight is active at any given time.
The enhancement produces nearly four times the throughput when all of the attached devices
on a port support 5250 Express Data Stream. All of the IBM devices from the original 5251 up
through the 3489 support the Express Data Stream.
