<DIV><FONT face=Verdana size=2>Hello,</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>We have a low-end platform of using Core2duo
(Xeon) with 4G ram.</FONT></DIV>
<DIV><FONT face=Verdana size=2>The budget is not much enough to afford
SAN.</FONT></DIV>
<DIV><FONT face=Verdana size=2>We consider SAS finally, but are still having
concerns about mail access speed.</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>This RAID could be:</FONT></DIV>
<DIV><FONT face=Verdana size=2>1. RAID 1 (OS) + RAID 1 (mail
spool)</FONT></DIV>
<DIV><FONT face=Verdana size=2>2. RAID 1 (OS) + RAID 5 (mail spool)</FONT></DIV>
<DIV><FONT face=Verdana size=2>3. RAID 50, for OS and mail</FONT></DIV>
<DIV><FONT face=Verdana size=2>4. RAID 10, for OS and mail </FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>Option 1 is found difficult to expand its mail
spool</FONT></DIV>
<DIV><FONT face=Verdana size=2>RAID 5 is not good for speed, but it can
expand</FONT></DIV>
<DIV><FONT face=Verdana size=2>RAID 50 speed is much slower than RAID 10, but
RAID 10 is very expensive</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>Anyone here can provide suggestions?</FONT></DIV>
<DIV><FONT face=Verdana size=2></FONT> </DIV>
<DIV><FONT face=Verdana size=2>Thanks</FONT></DIV>
