Chapter 1. CNA-8000 Overview
The CNA-8000 is an enterprise class server providing gateway functions targeted at
replacement of several existing products, many of which have been discontinued and
unsupported by their respective vendors. Through careful implementation, it is possible
in many cases to deploy the CNA-8000 with little or no impact on the end users.
Target Market
Although the product platforms that the CNA-8000 can replace are many, you should
carefully compare the functions currently supported on your existing product platform to
the feature set of the CNA-8000 to ensure that it will be a complete and successful
replacement. Among the products that the CNA-8000 may replace are:
Cisco CIP: TN3270 Server, PU2 Gateway
Cisco CPA: TN3270 Server, PU2 Gateway
IBM 3172: PU2 Gateway
IBM 2216: PU2 Gateway
IBM 3745: Token Ring PU2 Gateway
IBM 3174: PU2 Gateway
Memorex Telex or Visara 1174: TN3270 Server, PU2 Gateway
McData 1374: PU2 Gateway
McData 6100: PU2 Gateway
Microsoft SNA Server: TN3270 Server
Numerous Other Non-Named TN3270 Servers
The CNA-8000 Hardware Platform
The CNA-8000 consists of an enterprise class 3U rack-mountable server with four PCI-x
slots and one PCI-Express slot. The base unit includes 2 independently sourced power
supplies that can be hot swapped as needed. Each power supply is capable of carrying the
complete load of a fully loaded CNA-8000 platform. Multiple redundant fans provide
cooling and may also be swapped without powering down. Two 10/100/1000 Mbps
Ethernet interfaces are included on the motherboard and do not consume any of the
available slots. A pair of Hard Drives in a Mirrored RAID 1 configuration provides
completely redundant code storage.
The CNA-8000 supports up to two ESCON interfaces, each capable of supporting up to
16 CU images and 256 subchannels. Each ESCON interface supports EMIF on the host
and ESCON directors, allowing communication with up to 16 LPARs through each
interface.
