<DIV><FONT face=Arial size=2>The way I understand it, IDE uses a lot of CPU time
if you have many </FONT></DIV>
<DIV><FONT face=Arial size=2>requests, SCSI uses next to none.. on one of our
servers (file/print/</FONT></DIV>
<DIV><FONT face=Arial size=2>terminal) we have a 4-drive SCSI array and one 80
GB IDE drive for</FONT></DIV>
<DIV><FONT face=Arial size=2>temporary storage... when anyone transfers large
amounts of data </FONT></DIV>
<DIV><FONT face=Arial size=2>to/from the IDE drive, the terminal services
sessions start to hang--</FONT></DIV>
<DIV><FONT face=Arial size=2>and this is a dual-CPU machine.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>Anyway, SCSI just does better for servers.. but can
definitely eat up </FONT></DIV>
<DIV><FONT face=Arial size=2>your budget. You could start with the IDE
drive--it will work--, then </FONT></DIV>
<DIV><FONT face=Arial size=2>depending </FONT><FONT face=Arial
size=2>on</FONT><FONT face=Arial size=2> how many hits you eventually get, the
IDE machine </FONT></DIV>
<DIV><FONT face=Arial size=2>may need </FONT><FONT face=Arial size=2>to
be</FONT><FONT face=Arial size=2> replaced with a faster machine sooner than if
you </FONT></DIV>
<DIV><FONT face=Arial size=2>started with a SCSI drive...</FONT></DIV>

<DIV><FONT face=Arial size=2>Yes, </FONT></DIV>
<DIV><FONT face=Arial size=2>With SCSI more then 1 application can access your
hard drive at a time.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>With IDE, only 1 aplpication can access your hard
drive at a time.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So If you go with SCSI, then if you have 10 people
request a map from your mapserver, then each persons request wont have to waite
for the previous request to finish( on the hard drive).</FONT></DIV>
<DIV><FONT face=Arial size=2>If you plan on getting a ton of hits( people using
your site), got with SCSI.</FONT></DIV>

<DIV> </DIV>
<DIV><FONT face=Arial size=2>I am setting up my map server on a shoestring
budget and was </FONT></DIV>

<DIV> </DIV>
