Hardware support
The UTS System Version 4 supports a broad range of hardware products, giving customers flexibility and a path for growth.
Processors.
Unlike competitive mainframe UNIX products, the UTS System Version 4 offers unique support for all major System/390 platforms. This support can be crucial in multi-vendor data centers and for
insuring flexibility when selecting disaster recovery sites.
The capacity range of the supported processors provides significant scalability options from the smallest Amdahl 7300-150 or IBM 9672-R11 to the largest Amdahl 5995M-12670 or IBM 9021-9x2.

The UTS System Version 4 uses industry-standard protocols and applications,allowing users on different platforms to share data quickly and efficiently.
Transmission Control Protocol/Internet Protocol (TCP/IP). The UTS System Version 4 permits the exchange of data over Ethernet, HYPERchannel, and FDDI networks. TCP/IP is supported over LAN gateways. Data can be transferred between UTS Systems (Version 4 or Version 2.1) using multiple channel-to-channel connections.
Open Systems Interconnection (OSI)/LAN. The UTS System Version 4 includes all seven layers of the OSI reference model. Optional application services available from Amdahl include OSI FTAM and the X.400 (1984) Message Handling System, which communicates over OSI LAN transports. OSI, LAN, FTAM, and the X.400 Message Handling System conform to U.S. GOSIP 2.0 and U.K. GOSIP 3.1 standards.
System Network Architecture (SNA). Several SNA capabilities are available as optional features. The UTS System Version 4 communicates over a PU5 channel connection to VM and MVS operating systems and provides LU6.2 Advanced Program-to-
Program Communication (APPC). SNA Parallel Transmission Groups allow multiple channel-to-channel connections between the UTS System Version 4 and the same MVS system. Network Job Entry (NJE) is available as an option across channel-to-channel attachments. Common Programming Interface Communications (CPI-C 1990), an element of X/Open's Common Application Environment, provides an API that enables conforming applications to communicate with other applications via IBM's LU 6.2 communication protocol.
Bisynchronous communications. Support for Remote Job Entry (RJE) allows file transfer between a host running the UTS System Version 4 and an MVS JES2 system.
Open Network Computing (ONC). The UTS System Version 4 supports ONC, including Remote Execution, Lock Manager, Auto-mounter, and the Network Information System.
UTS kernel facilities
The current UTS release provides a full set of features and capabilities to optimize system performance.
Symmetric multiprocessing. Full symmetric multiprocessing support for most STREAMS-based communications protocols and all multiprocessor configurations of System/390 families is provided, up to the largest 12-way models.
Expanded storage. A facility within the UTS System Version 4 enables use of additional accessible processor memory (up to 8 gigabytes on Amdahl 5995M models) as paging devices or temporary file systems.
Process scheduling. This facility supports real-time, time-sharing, and scaled fair-time scheduling.
Modularized kernel architecture. This design is based on the UNIX System V Release 4.1 Enhanced Security operating system.
Expanded Fundamental Types. This feature allows expansion of certain data types that have outgrown their original capacity.
Shared libraries. Support is provided for dynamic shared libraries and for static shared libraries that have been created by the UTS System Version 4.
Driver interfaces. The UTS System Version 4 supports the pre-SVR3 version signal, the SVR3 version sigset, and the SVR4 and POSIX-compliant version sigaction.

Relational database support
Recent releases of third-party relational database products are available, including:
Enhanced system management
The UTS System Version 4 includes numerous features that facilitate effective system management.
Backup and restore. The UTS System Version 4 facilities schedule and automate the execution of backups, and support incremental and online backup. This provides a consistent operator interface that is independent of the local file system type.
Simple Network Management Protocol (SNMP). The UTS System Version 4 provides agent support for SNMP. SNMP specifies a standard format for communicating network management information among nodes on a TCP/IP network.
Console switching. In order to increase the availability of the UTS System Version 4, Amdahl has added a facility enabling the UTS console to be switched to any locally attached 3270 device (or equivalent). This allows the UTS System Version 4 to be managed from anywhere in the data center, thus reducing thepossibility of system outages due to failure of the UTS console.
Remote Operations Interface (ROI). ROI is an optional UNIX feature that defines library routines, utilities, and commands which provide network-independent services. This allows applications to administer othersystems that provide the same interfaces.

CD-ROM document distribution. Technical publications for the UTS System Version 4 are distributed on CD-ROM media, giving users the convenience of having both text and graphic information available at their fingertips. Hard copy technical publications are available as a separately priced option.
Scalability for growth
Operating on a broad range of System/390 processors, UTS System Version 4 helps customers rightsize applications and provides a path for future growth.
Enhanced interoperability
Compliance with major industry interface and communications standards, combined with support for the proprietary MVS operating system interfaces, establishes Amdahl's UTS System Version 4 as the ideal host for complex heterogeneous computing environments.
3270 terminal support
In order to assist users during the transition period of migrating to an open
systems environment, Amdahl has taken the unique approach of supporting not
only intelligent client desktop systems but also older model 3270 terminals as
well. Flexible 3270 terminal support is provided through these features:
Tube Driver. A special terminal driver is provided to efficiently serve
the requirements of directly connected 3270 terminals.
SIM3270. The SIM3270 feature is host-resident software which
automatically emulates 3270 terminals on ASCII terminals connected to
applications using 3270 command streams.
3270TN. This feature provides all of the ASCII communication features
of telnet for 3270 terminal users in environments using telnet and/or TN3270
protocols. This enables users to remotely connect to other UTS, MVS, or VM
hosts over a TCP/IP network from a full-screen 3270 terminal.
TN3270. The TN3270 feature combines telnet protocols with full-screen,
3270 terminal emulation for ASCII terminals or ASCII windows on PCs and
workstations. This feature is based upon the public domain TN3270 application.
