I am new to this news group, so if I am posting a news that usually goes to another group, please forgive me. I need the following information on the Sparkstation 1: 1. How many terminals (plain terminals like vt100 or tvi950 as well as Sun graphics terminals) can be directly connected to the Sparkstation 1? 2. How many people get onto the machine at the same time without any noticeable decline in speed and performance? 3. Can this machine support up to 2 gigabytes of hard disk space? 4. Is there a way that the machine can be connected to the Internet using high-speed modems so that we can use ftp and telnet in their full functionality? These are the questions I have right now. I am considering buying a Sparkstation 1 for a research project that deals with huge databases. Do any of you have some experience with SAS under SunOs? Have you had and problem with SAS in dealing with big data set (bigger than 20 megabyte)? I would appreciate any help coming in my way. Please e-mail me. Thanks in advance, Min

|From: soh3@tank.uchicago.edu (min-woong sohn) |1. How many terminals (plain terminals like vt100 or tvi950 as well as Sun |graphics terminals) can be directly connected to the Sparkstation 1? The SPARCstation 1 has two RS-232 ports. I believe there's an S-bus board available from Sun with four more. Or you could buy Uninet's nifty SCSI serial box. Or you could buy a terminal server. What do you mean by Sun graphic terminals? |2. How many people get onto the machine at the same time without any |noticeable decline in speed and performance? Depends upon what they're doing, of course. With enough memory, you should be able to support several folks banging away pretty hard. If they're mainly reading mail and staring at prompts, several more. |3. Can this machine support up to 2 gigabytes of hard disk space? Sure. Hang some big Wrens (-6s and -7s) on the SCSI bus. |4. Is there a way that the machine can be connected to the Internet using |high-speed modems so that we can use ftp and telnet in their full |functionality? Sure. I'm doing SLIP with mine right now. With a pair of Trailblazers and the new compressed-header SLIP on both ends, things are reported to be pretty pleasant. Not as nice as real T1 connectivity, but adequate.
