RS/6000 7044 Model 170 Technical Overview
RS/6000 7044 Model 170 Technical Overview The IBM RS/6000 family is a scalable, software-compatible line of RISC UNIX workstations, servers, and supercomputers powered by IBMs AIX operating system. On February 7, 2000, IBM announced two exciting additions to this family, the 44P Models 170 and 270.
Ethernet (AUI and RJ45), parallel, two serial (9-pin D-shell), tablet (for use with legacy input devices), Ultra2 SCSI VHDC, and stereo/audio. To connect external SCSI devices to the Ultra2 SCSI adapter’s VHDC, order # 2118 (mini-68 pin VHDC to 68 pin). This 0.3 m long cable (P/N 76H0518) is not included with the minimum system configuration. The Model 170 offers many optional features. The media bay can hold a second CD-ROM device, a 4 mm or 8 mm tape drive, or a SCSI disk drive.
System Upgrade There are no system model upgrade conversions available for the 44P Model 170. Processor and memory expansion options are available for this system. The Model 170 is designed for customer setup of the machine and for the subsequent addition of most features (adapters and devices). Architecture and Technical Information A diagram of the system architecture and logic flow for a 400 MHz system is shown in Figure 2.

Copper and CMOS Technology The use of copper in chip design addresses several or the aspects that inhibit performance: power load, generated heat, clock signal distribution, and chip size. The complexity of the chip design (roughly equated to the number of transistors) when combined with the lithography process determines the size of the die.
Following is an example of the processor card information for a 333 MHz Model 170: Processor Card: Part Number.................11K0857 EC Level....................D72830 Serial Number...............L200016008 FRU Number..................00P2180 Manufacture ID..............1980 Version.....................RS6K Product Specific.(ZC).......PS=0013D92D40,LB=0009EC96A0, SB=0005ABC3C9,NP=01,L2=01024, PF=711,SV=3,VR=2,ER=0000 Product Specific.(ZB).......
Memory The system supports from 256 MB to 2 GB of ECC SDRAM using a 128-bit wide memory bus. Memory bus speed varies dependent upon processor selection. The enhanced memory controller uses a 95.1 MHz memory bus speed on the 333 MHz system and a 100 MHz memory bus speed on the 400 MHz system. There are four memory slots available in the 44P Model 170. The Dual Inline Memory Modules (DIMMs) are ordered and installed in pairs.
Memory Boot Time Deconfiguration Memory boot time deconfiguration is a function implemented in the service processor firmware to remove a memory segment or DIMM from the system configuration at boot time. The objective is to minimize system failures or data integrity exposure due to faulty memory hardware. The memory segment or DIMMs that are deconfigured remain offline for subsequent reboots until the faulty memory hardware is replaced. This requires powering off the system.
A variety of PCI adapter, controller, graphics accelerator, SCSI, LAN, WAN, asynchronous, and SSA cards, to name a few, may be installed in the 44P Model 170. Specific information on selected adapters is provided in the following sections: LAN Adapters The Model 170 can be connected through the LAN.
Internal Disk Bays and Media Bays The disk bays provide from 9.1 GB to 72.8 GB of internal storage space and are populated with a combination of the following disk drives: • 9.1 GB 1" Ultra SCSI Hard Disk Drive (# 2908) • 18.2 GB 1" Ultra SCSI Hard Disk Drive (# 2909) • 9.1 GB 10 K RPM Ultra SCSI Hard Disk Drive (# 3027) • 18.2 GB 10 K RPM Ultra SCSI Hard Disk Drive (# 3102) Note The 18.2 GB 10 K RPM Ultra SCSI disk drive is not supported for installation in the media bay, but is allowed in the disk bay.
Miscellaneous The following general information is included for convenience: DVD Support Currently, Digital Versatile Disc (DVD) drives are not supported in RS/6000 systems. ISA Support The Model 170 does not support industry standard architecture (ISA) adapters. USB Support The Model 170 does not have integrated Universal Serial Bus (USB) support and no USB adapters are currently available for use in RS/6000s.
The RS/6000 PCI 3-Channel Ultra2 SCSI RAID Adapter (# 2494) does not provide boot support from external devices. Fast Boot The Model 170 offers a Fast Boot option. For more detailed information, refer to “Selected Service Processor Functions” on page 10. Security To prevent the system from unauthorized booting from a CD-ROM device, a power-on-password (POP) or a privileged-access password (PAP) may be used.
