I recently spoke with someone who needs a large computer (a few hundred users, I think). He wants to run UNIX, but hasn't seen a single computer that's able to handle this number of users. The type of hardware he is thinking of is a VAXcluster - several VAXen sharing all peripherals- but he said DEC doesn't have Ultrix support for it. Does anyone know if there is a version for UNIX that does support this hardware? (The system he has now shares files over an ethernet, but is not the system of choice). Thanks in advance.

This with the supported NFS included will probably give you what you want. Fred ---- NFS is a trademark of Sun Microsystems, Inc. ULTRIX is a trademark of Digital Equipment Corporation

They are used for general office automation-type work. Machine configuartions are as follows: Users Disk Storage Capacity ----- --------------------- 257 2736 MB 631 4436 MB 748 4436 MB These systems are working fine with these configurations. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Michael J.

I'm not so sure that he is looking for a system that can handle several hundred users at once. If he is, then I think that he will have a hard time finding anything. /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ Michael J.

It is my understanding that ARIX is one of the only manufacturers with UNIX models that will handle hundreds of simultaneous users. -- John E Van Deusen III, PO Box 9283, Boise, ID 83707, (208) 343-1865 uunet!visdc!jiii

An Amdahl 5990-1400 with four engines, each ~60 VUPS (yes, its rubber ruler time again - insert usual disclaimers) running SysV native is handling this load for a number of our customers. Some of them are banging on us to expand the 1024 device limit so they can add more users/more disk (1.8 terabytes isn't enough). I apologize for the blatant commercialism, but I couldn't stand seeing all these little UNIX engines being called big anymore... -- UUCP: littauer@amdahl.amdahl.com or: {sun,decwrl,hplabs,pyramid,ames,uunet}!amdahl!littauer DDD: (408) 737-5056 USPS: Amdahl Corp.
