RE: Sun to Linux on Dell

Title: Message

I'd go Windows on the Dell box.  There are some quite nice tools like perfmon that can give you a lot of info about what is going on.  My preferred Windows box though would be the Proliant, it's earned it's reputation over time for performance and reliability.

 

Problem with a big system though is the cost of the port.  I'd tend to stick with a SUN box with a SAN but do the sums.

 

If you want sheer performance dump the disk drives except a couple mirrored for the operating system then go something like an HP SAN.  We've seen thirty fold improvement on some databases going SAN keeping the same server.

Subject: Sun to Linux on Dell

I have a cust pounding a Sun E450 I believe they

said it was with a large RAID with fiber channels.

 

They pound this thing at 2,037 I/O per seconds and

end up having about 3,868 I/O per data block wait.

This is averaged over 3-5 days, 24 hr/day, so there

are times it's way over that. While sometimes slow,

performance is acceptable most of the time.

 

They are contemplating moving it to Linux and a

very high end Dell system, perhaps 4-8 CPU, etc.

 

I've always heard Sun was pretty much the best

on heavy I/O and if it were not for the

fiber channels, they would probably have

been hurting big time some time ago.

 

They are only in R&D right now, but has anyone

done a move of this nature?

 

The database is Siebel with many mods and

sub systems, average tuned, about 76gb. It

is about 139 million records. They are around

200 users or so.
