RE: Sun to Linux on Dell

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.

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.

  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

  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

  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.
