Pyramid (original) (raw)

summary

“Pyramid uses the MIPS chipset, and did the reference port of SysVr4 to those chips under contract to Unix System Laboratories (USL). Pyramid runs Sys V, release 4.2 (with their own enhancements).” —Chad R. Larsone50

Intended purpose

server/mainframe: medium to large scale servers; mainframes

desktop/workstation: workstations (for those with UNIX familiarity)

handheld: not appropriate

real time: not appropriate

Kind of OS: proprietary UNIX e50 †

“Note that it does support the mips abi. Unfortunately, virtually nothing is compiled for the mips abi, but instead compiled for the specific os (sgi irix, sony, whatever.)” —Mark Wedele96

Release Date:

Current Version:

1.1-[cd]087.4 for nile and mis seriese96
reliant unix 5.43C20 for rm1000e96

Cost:

Hardware Supported: MIPSe50

Maximum Number of Processors: 24e65

“This really depends on the model — as far as I know, the OS does not limit the number of processors — only the amount of physical slots.
“That said, the MIS 2, 4, and 12 have 2, 4, and 12 slots for CPUs. The later MIS-ES series had 2 processors per board (earlier models had 1 cpu/board). So in theory an MIS-ES could have up to 24 processors.
“The nile 100 has 6 R-bus slots, NS 150 has 12 r-bus slots. At least one of those slots will need a memory board, and another will need an RXI. So that leaves 4 or 10 rbus slots for dpu's (2 cpu/board).
“The mis-s is an r3000 @ 33 mhz, mis-es is r3000@37, and the niles are r4400 at either 150 or 200 mhz.
“For the rm1000, the number of processors is not as simple — each node in the system has 1 cpu, but some nodes can be either niles or rm600s. So a one cell rm1000 could have 4 corner nodes (4 cpu's) + 2 nile nodes (22 cpu's). In mile configuration, the niles do not need the RXIs.
“I have limited this to pyramid proper hardware. The SNI hardware (other rm model numbers) vary system to system — generally, the higher the number, the more power the system can have.” —Mark Wedele65

Number of bits: 32e96

Kernel:

POSIX: compliante96

Peripherals:

“Niles boards include dens (dual ethernet) xni (two wide scsi), and a variety of other comm products (fddi, token ring, …). Fast ethernet currently not supported, and support of scsi devices is fairly limited.
“mis support xvi (2 fast scsi), den, above mentioned comm products, as well as iop drives, ios scsi (2 scsi 1 interfaces), and itp (16 port serial boards).
“All scsi above is differential.
“Rm1000 are a hot swapable backplane with hot swapable drives (wide scsi). Included is additional scsi ports and ethernet. PCI nodes can be installed, with a variety of cards supported (fddi, fast ethernet, and I am sure many more).” —Mark Wedele96

File Systems Supported: rxfs (basically vxfs), ufs. Nile, rm100 also use tfs for /stand partitions.e96

Other Systems Emulated:

Graphics Engine: “No on board graphics hardware. These are servers that sit in the back room — remote display via X11 is what is used.” —Mark Wedele96
