Replaced by IBM 9032-005

The IBM 9033 ESCON* Director provides channel connectivity using fiber optics and the Enterprise Systems* Connection Architecture for selected models of the ES/3090J, the ES/3090 9000T, and the ES/9000* processors. It provides for connection and switching among ES Connection channels and control units. The ESCON Director ranges in size from 8 to 16 connection ports, in increments of four, that may attach to either channels or control units. The ESCON Director supports attachment of the 9034 ESCON Converter Model 1, which allows attachment of control units with parallel interfaces, thus easing the migration to the Enterprise Systems Connection Architecture. The ESCON Director also supports attachment of the 9035 ESCON Converter Model 2 that allows 3990 Storage Control Units with ESCON adapters to attach to parallel channels on selected ES/3090 and ES/4381 processors. For all models of the ESCON Director, new cables or conversion kits are required for attaching XDF port cards.

Model Abstract 9033-004

Model 9033-004 offers 8 ports minimum, upgradable to 16 ports maximum. The Hardware Management Console Support option allows the customer with an installed S/390 CMOS processor to provide Console support for 9032 Model 2 and 9033 Model 4 from the system Hardware Management Console instead of a dedicated console.

Highlights

• 16 port capability
• Dynamic addition of ports (hot plugging)
• Ability to support consoles at extended distances
• Compact, tabletop design
• Concurrent Maintenance capability for port cards and token ring card

Model Highlights 9033-004

• Improved business solutions are afforded by the less disruptive installation and reconfiguration characteristics as well as via the LED and ESCON XDF* link distances that can be achieved. Contact your local Marketing representative for a review of all local and extended-distance configuration options and opportunities.
• Business solutions are further improved via the concurrent, nondisruptive upgrades and replacements of port cards and token ring card during normal operation. This capability provides higher up-time and more flexible operations.
• The high-performance characteristics of the 9033 Model 004 allow the maximum, 16-port configuration to sustain 8 port pairs simultaneously connected and actively passing data.
• Additional LED and ESCON XDF port cards can be added while the 9033 Model 004 is operational. Any LED or ESCON XDF port can be configured as a spare port and can be activated as required from the console (Operator/Service console).
• Investment protection and migration flexibility are provided through attachment support of the 9034-001 (9034 ESCON Converter Model 001), the 9035-002 (9035 ESCON Converter Model 002), and the 9036 (9036 IBM ESCON Channel Extender).
• User productivity is further enhanced by changes in console support. The console is attached via a token ring and can be located at distances up to the limit of the installed token ring. The console application software runs under OS/2 and has a windows-based user interface. A console is required for installation, configuration, and operator control of the 9033 Model 004.
• The console function can be provided by the Hardware Management Console of any installed S/390 CMOS processor as an alternative to a dedicated console. The Console Support Code supplied with the Director must be loaded on the HMC to provide this function. For further information refer to Maintenance Information Manual SY-2638-00.
  A console is not required for the 9033 Model 004 to be operational. If a console failure occurs, the 9033 Model 004 continues to operate while the console is being repaired or control is being transferred to a spare console. The 9033 Model 004 has flash memory that retains the current configuration if its power is turned off. This means that, if a console failure occurs and the 9033 Model 004 is powered down, when it is powered up operations can continue per the current configuration.
• Availability is improved by the concurrent maintenance capabilities of the port cards and Token Ring card. This allows service to be performed on the port cards or Token Ring card while the 9033 Model 004 is in normal operation, without disruption of the customer environment.

Technical Description

The 9033 Model 004 is a dynamic switch that accepts data streams through its fiber-optic ports; decodes destination port addresses contained in the data stream; makes internal routing connections; and passes the data streams to the addressed ports. A destination or source may be either a channel or a control unit. Up to 8 port pairs may be simultaneously connected and actively passing data.

The 9033 Model 004 is a table top unit and is available in sizes ranging from 8 ports to 16 ports in increments of 4 ports. If initially ordered with less than 16 ports it can be field upgraded, in increments of 4 ports.

A console is required and is available as a priced feature, or must otherwise be supplied by the customer. One console can manage up to 16 clustered 9033 Model 004s and 9032 Model 003s.
The 9033 Model 004 CANNOT share a console with a 9032 Model 002 nor a 9033 Model 001 but can share a console with 9032 Model 003. As an alternative to the use of a dedicated console and token ring just for the ESCON Directors, the customer has an alternative to provide the required console function. If the customer has an installed S/390 CMOS processor with the Hardware Management Console, that console and token ring can be used to provide the console function of the ESCON Director also. This applies to both the 9032 Model 003 and the 9033 Model 004. The console code shipped with the Directors must be loaded on the HMC to activate this function. This capability allows the customer to avoid the expense of purchasing a separate console and token ring. For further information refer to the Installation Instructions provided with this feature.

A 9033 Model 004 can be chained, via the ESCON fiber optic interface, with any 9033 or 9032 ESCON director provided the connection ports in one or both are defined as dedicated connections. A maximum of two Directors can be chained. One console can manage up to 16 clustered 9032 Model 003s and 9033 Model 004s. Please refer to the "Operator/Service Console" section for a detailed discussion of the console.

Although the 9033 Model 004 allows any port to communicate with any other port, communication among ports may be configured, within device limitations, to satisfy application requirements. This configuration capability can be accomplished using the windows interface at the console, or if host configuration control is desired, by using the ESCON Manager (5688-008) licensed program. If ESCON Manager is to be used, there must be at least one ESCON channel connection between the host and the 9033 Model 004. Prestored configurations at the local console are also allowed, and can be transferred to and from the host. The configuration can be changed by:

1. Defining a dedicated connection. A dedicated connection connects two ports together continuously, to the exclusion of all other ports.
2. Blocking a port such that it cannot communicate with any other port. It can be unblocked as required.
3. Partitioning resources by prohibiting a port or groups of ports from communicating with other ports. This partitioning capability allows the 9033 Model 004 to be logically configured into multiple independent partitions.

Point-to-point distances of up to 3 kilometers (km) cable length are supported when LED ports are installed. Using a properly positioned 9033 Model 004, channel-to-control-unit or channel-to-channel distances of up to 6 km can be achieved. A maximum of 9 km can be achieved using two, chained 9033 Model 004s, or with a 9033 Model 004 chained with a 9032 Model 002, 9032 Model 003, or with a 9033 Model 001.

With ESCON XDF point-to-point distances of up to 20 km cable length are supported. Channel-to-control-unit distances of up to 43 km can be achieved for selected control units. The maximum achievable distances are control unit dependent. Channel-to-channel distances of up to 60 km can be achieved.

The 9033 Model 004 maintains a local audit trail on the console's hard disk. This audit trail records the time, date and password for certain changes made from the console.

The 9033 Model 004 provides a password facility that protects against unauthorized use of selected functions. This password facility is controlled at the 9033 Model 004's console and is independent of other system security mechanisms. Three levels of passwords are implemented:

• Level 1 - Allows a user to control the passwords of other users who have access to the 9033 Model 004.
• Level 2 - Allows the service representative to perform maintenance procedures.
• Level 3 - Allows the user to change connectivity attributes and to access certain utilities.
