Remote management through Visara's eManager product
In the past, supporting multiple mainframes or multiple partitions
on a single mainframe, meant keeping a separate console controller
for each logical partition. Newer, mainframes make it increasingly
difficult to find replacement console controllers that will connect
directly to the mainframe without having to implement costly and
cumbersome ESCON to channel converters. With the Visara SCON product
family running LINCS software, you can run consoles for up to 32
LPARs through a single platform. The SCON solution is scalable,
allowing for the perfect solution for anywhere from 1-32 partitions
per platform over one or two ESCON connections, and providing a
combination of traditional device connections, as well as a variety
of LAN and remote connections.
Console Controller Consolidation
The SCON-2XL allows you to consolidate your consoles for up to 32
LPARs onto a single Console Controller platform. The SCON-2XL communicates
to your mainframe(s) using one or two ESCON interfaces. Console
terminals can be directly attached to the 2XL using coax or twisted
pair wiring. Password protected Telnet connections are supported
as well via 10/100 Mbps Ethernet or 4/16 Mbps Token Ring, using
a variety of terminal emulations, allowing for remote consoles and
remote management of the 2XL.
Using the Visara 1883 Networking Computing Terminal, you can communicate
across the network or through a dialup connection to the SCON-2XL
using TN3270 protocol. The Visara 1883 contains special code required
to display console sessions, and permits the simultaneous viewing
of up to 4 consoles on a single screen.
Individual terminals can be used to view console sessions for multiple
LPARs. Access to up to 10 different LPARs can be made from any fixed
function terminal. Multiple LPARs are supported by making use of
ESCON Directors and/or by using EMIF.
The SCON-2XL is a rugged dedicated communication platform, designed
exclusively for the support of mainframe consoles, not some wimpy
PC platform, vulnerable to computer viruses. The SCON-2XL does not
emulate a console controller, it is a console controller! Perhaps
the very best!
Multiple Console Sessions on a Single
Console Display
The SCON-2XL permits each coax terminal to have up to 10 concurrent
sessions. These sessions can be defined to be on one or more LPARs.
An optional windowing feature is available on the 2XL to permit
portions of up to 5 sessions to be displayed on any fixed function
coax terminal. When using the windowing option, sessions can be
zoomed to full screen with a keystroke. Session swap keys allow
the user to move from one console session to another. Update indicators
in the status line identify when a background session has been updated.
In the diagram above, each of the terminals could have one or more
sessions to each of the six LPARs. Each terminal could have a total
of 10 sessions at one time.
The Telnet/TN3270 Connection
Now from a single desktop, you can communicate to as many LPARs
as you need to by utilizing the Telnet or TN3270 facilities of the
SCON-2XL.
Using Telnet or TN3270, you can connect to any of the LPARs defined
on the SCON-2XL. And it does not stop there. If you have multiple
SCON-2XLs, you can establish a connection to any of them, using
the standard network interface.
The Telnet interface provides a simple connection into the SCON-2XL,
using nearly any Telnet device or emulation. You can even use the
standard Telnet interface provided by Windows-based PCs to display
a console session. Specific IP Address and TCP port assignments
and passwords provide security.
Once connected, the Telnet user can communicate with whatever resources
have been assigned to them, up to 10 sessions (LPARs) at one time,
or select sessions from a menu.
TN3270 provides a superior user interface over Telnet, by providing
a more natural 3270 interface. The number of sessions from a desktop
and feature/functionality are dependent upon the emulator.
The above diagram shows a single Visara 1883 NCT configured for
TN3270 and would be capable of initiating a session to any or all
of the 9 LPARS shown at one time, and could display up to 4 complete
sessions on the screen at one time. The 1883 could also communicate
to yet another SCON-2XL located remotely via either a routed network
connection or through a dialup connection.
Support for IBM 3290 Displays
The SCON-2XL provides connectivity for the IBM 3290 Plasma display.
Up to 4 sessions can be displayed on the 3290 at one time. For a
current product to provide the same functionality, as well as provide
color support and multiple SCON-2XL access, refer to the Visara
1883 product.
The Visara 1883 Solution
The Visara 1883 desktop Network Computing Terminal is capable of
communicating directly to the SCON-2XL as a coax terminal, through
Ethernet, or through a PPP dialup connection. The 1883 supports
up to 10 sessions via its TN3270 emulator, with the ability to show
up to 4 full complete sessions on the screen at one time. A special
command set is integrated into the 1883 product, which allows them
to support mainframe console sessions through the TN3270 client.
All sessions may be cascaded on the screen at once. These 10 sessions
can be to the same or different LPARs and to the same or different
SCON-2XLs.
In addition to the standard integrated Ethernet connection and
optional coax (3270) connection, twinax (5250), and Token Ring interfaces
are available. With the coax interface, you can connect directly
to the SCON-2XL, using the built in 3270 terminal function. A 122-key
keyboard has all of the traditional 3270 key legends. The 1883 is
a fully functional 3270 coax terminal, with many advanced features.
The Coax to Ethernet (C/E) Bridge feature of the SCON-2XL (U.S.
patent applied for), can be enabled to provide a coax-attached 1883
access to an IP network via the SCON-2XL's Ethernet card. The 1883
NCT supports a full IP protocol stack, and through the SCON-2XL
can communicate through the coax as if it were directly attached
to the Ethernet network. This is in addition to the 10/100 Mbps
native Ethernet connection available on the 1883. This is an ideal
product to provide console access to both local and remote sites.
Additionally, the 1883 has the functionality to support connections
to mid-range hosts using a TN5250 emulation, connections to a Unix
host using VT220, ability to run Windows applications through a
server using ICA, and access the web with its built in browser.
A serial interface comes standard on the 1883, allowing for remote
dial access. Through this connection, you can dial into a remote
SCON-2XL directly, through a RAS server onto your corporate network,
or even into an ISP for Internet access. With this capability it
is possible to manage remote data centers from your desktop, or
manage your own mainframe from home!
The diagram shows three different ways to connect the Visara 1883.
Direct coax attachment to the SCON-2XL
Ethernet attached to the SCON-2XL through a WAN network connection
Ethernet attached to the SCON-2XL through a LAN network connection
Through the coax connection, the 1883 can communicate like a standard
3270 terminal, or with C/E Bridge enabled, TN3270 (along with various
other IP features).
Through the Ethernet connections, the 1883 would communicate with
the SCON-2XL using TN3270 or Telnet.
Storage Tek Silo/LMU Support
Since the SCON-2XL is a real coax controller, you can use it to
manage Storage Tek Silos via the LMU. The 2XL can interface the
LMU up to as many different LPARs as needed.
The diagram shows a Storage Tek Silo/LMU connected to the SCON-2XL
through a coax mux, each coax line connected to a different LPAR.
Optional Hot Console Sessions Feature
for Remote Access
An optional feature available on the SCON-2XL allows you to configure
one or more console sessions as "Hot Console Sessions",
primarily for remote access applications. With a "Hot Console
Session", the session remains active with the host, regardless
of whether any device is actually connected to the 2XL and receiving
the messages. The "Hot Console Session" appears to the
host as though a coax terminal is always attached, thus providing
immediate console message access to a connecting user (Telnet or
TN3270), without requiring someone else to vary the console active.
Multiple User Access to the Same Session
Using an 1883 desktop and VNC software, available from Visara, it
is possible to provide multiple user access to the same console
session. The 1883 NCT provides the actual session access through
the SCON-2XL, then in turn allows access to any client running VNC
software (password protected of course). VNC clients can run on
a variety of platforms and operating systems, including Windows,
Linux, and Unix. Access to the 1883 can be through any IP connection
that you wish to provide. From the VNC application, you can view
the screen contents of the 1883, and provide mouse and keyboard
input as if you were sitting in front of the 1883 itself. Mouse
and keyboard input can be generated from the 1883 or VNC clients
and the results viewed by all.
Some of the benefits of this feature include:
Remote NIP console access for software developers
Remote training
Remote Problem diagnostics
Offsite Emergency Access
Centralized Management of Multiple Remote Sites
Remote Management Through Visara's eManager
Product
eManager is a remote management tool offered by Visara for the purpose
of remotely managing Visara products from a central location.
The SCON-2XL can be accessed and managed using the eManager product,
running from a remote Windows PC desktop. Among the tools provided
by eManager are Telnet and VNC clients, allowing remote access to
both the SCON-2XL and 1883. eManager provides the means to backup,
view and change configurations on the SCON-2XL and 1883 products.
Additionally, eManager can be used as an aid to help remotely diagnose
problem situations through its ability to pull SCON event logs,
display error code information, and display status information,
using a number of point-and-click utilities.
