RE: Sun to Linux on Dell

There's just not enough performance info here to go on. If the service times for the storage are high, simply improving the back-end storage (faster drives, more spindles, more cache, etc.) could solve the problem.

As far as Solaris vs. Linux cost, its definitely true that a Linux server _could_ be more expensive than an identically powered Sun server, though I bet over three years the price difference would swing the other way. Even taking that into account, though, the real cost savings of Linux come into play with RAC. First, the Intel hardware is a much faster at <4 cpus than above - 2.0 ghz on 4-way boxes vs. 900mhz at 8-way (and it goes up again when you go down to 2-way servers - 3.0ghz available), and the price-performance ratio improves as well. So, rather than buying one 4-way server, it can be cheaper to buy three 2-ways and end up with more RAM and more CPU power, even taking into account the overhead with RAC.

However, in this particular case, none of this will help you if its your storage that's the bottleneck.

Thanks,
Matt
