The IBM RS/6000* S70 Advanced Model S7A is a member of a new generation of 64-bit, 4-way, 8-way, or 12-way, symmetric multiprocessing (SMP) enterprise servers. The S70 Advanced provides the power, capacity, reliability, and expandability to help move you into the next generation of mission-critical commercial computing. With the S70 Advanced, you can manage the evolution of your business into 64-bit computing while still supporting your existing 32-bit applications. The I/O subsystem will support 32-bit and 64-bit standard PCI adapters. The S70 Advanced delivers a cost-efficient growth path to the future through these attributes: 64-bit system scaleability; 4-way, 8-way, or 12-way--packaged on 3 processor cards (4 RS64 II processors per card); 262 MHz system processors; and 8 MB of L2 ECC cache for each 262 MHz processor.
The S70 Advanced is packaged as a Central Electronics Complex and an I/O rack. The S70 Advanced Central Electronics Complex entry configuration starts with a 4-way scalable SMP system that utilizes the 64-bit, 262 MHz, RS64 II* processor with 8 MB of Level 2 (L2) cache per processor. The 4-way SMP can be expanded to a 12-way SMP and the system memory can be expanded to 32 GB.
The I/O rack contains the first I/O drawer with:
Service processor
High-performance disk drive
32X Maximum speed CD-ROM
1.44 MB, 3.5-inch diskette drive
Two PCI disk adapters
Up to three additional S70 Advanced I/O drawers can be added. Additional I/O racks can also be ordered with the S70 Advanced. Existing RS/6000 7015 Model R00 racks or the 7014 Model S00 rack can also be used for additional storage and communication drawers. This helps to protect your existing investment in SSA or SCSI DASD.
A fully configured system would be a 12-way processor with:
32 GB of system memory
55 available PCI adapter slots
48 hot-pluggable disk bays
7 available media bays
The remaining space in the I/O racks can be used for various storage and communication subsystems.
The RS/6000 Enterprise Server S70 Advanced is shipped and delivered with all the internal adapters and devices already installed and configured. AIX Version 4.3.2 software is included with every S70 Advanced and can be preinstalled, if desired.

RAS Features and Functions -
Excellent quality and reliability are inherent in all facets of RS/6000 products. The measures taken help ensure that the products operate when required, perform reliably, efficiently handle infrequent failures in a nondisruptive fashion, and provide timely and competent repair to allow resumption of operations with minimal inconvenience. Reliability begins with the development of architectures, where RAS innovations are of paramount importance. It flows through design and product development stages, where RAS designs are reviewed, assessed, developed, evaluated, and optimized. It continues through the manufacturing and release processes, where the manufacturing quality is extensively measured and is under continual evaluation. It culminates in service and support, where reliability is consistently monitored for deviation from the criteria, warranty and maintenance have undivided focus, and where significant customer business problems are assigned to a key managerial representative and remedied by an expert team.
RS/6000 system processes, from the architectural and concept phases of development through the provision of service and support, are ISO certified and audited periodically for ISO compliance by representatives of Underwriters Laboratories.
Reliability & Fault Avoidance -
Major effort has been spent on the development of the S70 Advanced system to analyze single points-of-failure within the central electronic complex (CEC) (comprised of the processors, memory, and the I/O interface) and to either eliminate them or to provide hardening capabilities to significantly reduce the probability of failure.
The best way to harden a system is to prevent errors from occurring. Components within the CEC were selected to provide "server" levels of reliability. These components provide the highest levels of reliability available within IBM and undergo additional stress testing and screening. During the design and development process, subsystems go through rigorous verification and integration testing processes. During system manufacturing, systems again go through a thorough testing process to ensure highest product quality level.
Extensive error detecting and checking circuitry is included to help ensure infrequent component failures are recognized and corrected automatically or properly reported for isolation and repair, thus preserving the integrity of data stored and transported in the system. Hardware and software failures are recorded in the AIX log facility and analyzed by error log analysis (ELA) routines to provide warning to the system administrator on the causes of system problems. This also enables IBM service representatives to bring along needed replacement hardware components when a service call is placed, thus minimizing system repair time.
DASD predictive failure analysis provides the ability to detect an imminent disk failure and report the findings through the AIX log. Then the disk can be replaced either immediately or scheduled at a later time, depending on the configuration of the DASD subsystem. With the RAID controller and the DASD hot-plug design, normal operation can continue in the presence of a failed disk and a concurrent repair can be often performed while the application continues uninterrupted.
Availability & Backup and Replication -
The S70 Advanced brings new levels of availability features and functions to the Enterprise Server. Within the CEC Rack, the N+1 power subsystem provides redundancy in case of failures in either the bulk or regulated power subsystems. Concurrent repair is supported on the bulk supplies while the regulators will initiate a deferred repair scenario. Optional uninterruptible power supply (UPS) systems are supported for this system.
The CEC cooling subsystem also has N+1 blowers, which can be replaced concurrently. In the I/O units, N+1 power and cooling is provided with the capability for concurrent repair.
Constant power monitoring hardware assists in detection of early loss of source power and notifies the operating system to effect an orderly shutdown. This same power monitoring hardware detects the loss of redundant bulk power supplies, regulators, fans, and blowers and reports them to the operating system for logging in the system error log and for notification for deferred maintenance.
The S70 Advanced uses AIX online (concurrent) diagnostics with error log analysis and service aids, which allow administrators or IBM service representatives to diagnose potential system malfunction without interrupting end-user operation.
Auto-restart options, when enabled, are designed to automatically reboot the system following an unrecoverable software error, software hang, hardware failure, or an environmentally-induced (AC power) failure.
These standard, high-availability features coupled with the optional High Availability Cluster Multi-Processing (HACMP) program provide unmatched availability in the UNIX marketplace.
Serviceability & Correcting Faults -
The S70 Advanced product is designed to be installed and maintained by a trained service representative.
Functions such as power-on and power-off, reading the service processor error logs and POST error logs, reading vital product data (VPD), and accessing NVRAM can be performed remotely. You can also enable console mirroring to monitor remote activity.
Flash updates for firmware can be performed on the system. Firmware updates are available from an RS/6000 support page on the Internet and can be downloaded and installed on the system.
Service Director -
Service Director for RS/6000 is shipped with every S70 Advanced system. There is no additional charge for its use as long as your RS/6000 processor is covered by an IBM Warranty or IBM Maintenance Service Agreement. Service Director requires a modem in order to dial for service.
The Service Director for RS/6000:
Monitors and analyzes system errors, and if needed, can place a service call to IBM automatically
Reduces the effect of business disruptions due to unplanned system outages and failures
Performs problem analysis on a subset of hardware-related problems and, with customer authorization, reports automatically the results to IBM Service
Service Support
Hardware service requests go to IBM's remote support center for initial problem diagnosis. This approach gives you direct access to skilled specialists. These specialists can either solve the problem over the phone or help get it resolved as quickly as possible. They are backed up by a highly-trained product engineering team to assist in problem identification and resolution.
Other Functions -
The S70 Advanced takes advantage of several new I/O adapters, including a S/390 ESCON channel adapter, a gigabit Ethernet adapter, and an RS/6000 SP system interconnect adapter.
The POWER GXT120P single-card graphics adapter attaches via the 32-bit PCI bus. It provides a low-cost, entry-performance, 2D graphics offering with resolutions up to 1280 x 1024. It also offers video acceleration features such as scaling and color space conversion. The GXT120P can support multisync monitors with at least a 64 KHz horizontal scan capability or DDC-2B-compliant multisync monitors with at least a 38 KHz horizontal scan capability.
Ultimedia Services 2.1.7 and Xlib APIs are supported on AIX Version 4.3.2.
All of this provides for a 4-, 8-, or 12-way SMP Enterprise Server to take you into the future of 64-bit computing.
