Harris NightHawk 4400 Realtime Summary: Req: info on Harris Nighthawk 4400 Keywords: Harris Nighthawk 4400 realtime 88100 unix Message-ID: <1991Mar11.132225.13679@hubcap.clemson.edu> Date: 11 Mar 91 13:22:25 GMT Sender: fpst@hubcap.clemson.edu (Steve Stevenson) Organization: University of Illinois at Urbana List-Id: We've gotten a good offer from Harris on a NightHawk 4400, an 88100 based realtime unix machine. This offer competes with an offer from DEC on a DECstation 5000. After reviewing the spec sheets, I'm pretty favorably impressed by Harris' offer. There are some questions that I'm hoping someone can help with. 1. What's the SPEC rating (or MFLOPS) of the 4400 as offerred? The 5000 does about 18.5 SPECmarks, the 3100 about 11.3. A SPECmark is a measure of floating point performance. Don't be impressed by MIPS - that's only integer stuff. 2. Are we getting: SCSI interface? 3100 and 5000 use the SCSI. Currently its a good interface for getting cheap peripherals. Eithernet interface? Thick or thin doesn't matter, but it must have it. A good FORTRAN compiler? We get VAX Fortran and the MIPS f77 from a software library. A console/workstation? DECstations come with 19" bw monitor, mouse and keyboard 8mm tape drive? Nice for compatibility and data ? Disk, ? cpus, ? memory 3. Does their UNIX support NFS? Network File Serve: allows disks to be shared across the network. Ultrix, the DEC version of Unix, (obviously) can do it. Does it include X11R4? X11 is a standard windowing system used for the workstations. R4 is the latest release. The new Ultrix doesn't have it, but it's very easy to add. Does their Unix support disk striping? Disk striping can significantly speed up i/o. The new Ultrix supports it. 4. What will it cost in maintenance: hardware and software? Currently we have no regular hardware maint, though we probably pay a few hundred per year for miscellaneous fix-ups, and we recently paid $2k for those department vaxs. Software is $600/year for VAXstation 2000's, $900/year for the VAXstation II, and $1200/year for the 3100 (I think). Those prices will change by next year. We receive access to the complete Ultrix op sys with no limit on the number of users, and various software packages (windowing, graphics, compilers for most popular languages, etc.) Potentially, a 4 CPU version of the 4400 could be almost 10x the speed of the 3100. That's quite a bit of raw computing power... A single CPU version should be at least twice as fast. By comparison, the 5000 is one and a half to two times faster. DECstation 5000 we are considering: $12k 19" bw monitor, mouse, keyboard R3000 MIPS risc processor, 16 Mb memory, 600 Mb disk 18.5 SPECmarks Ultrix 4.0 (BSD 4.3) and MIPS f77 compiler SCSI device (up to 7) and thin Eithernet Prices could change soon as DEC is set to announce a new (faster) version of the 5000.
