Moving from P3 to Xeon
Hello! I have a server running RELENG_4_9 on IBM eServer 220 (P3 CPU). I have 'CPUTYPE=p3' in /etc/make.conf and I've built world (and a lot of ports) using this CPUTYPE setting. Now, suppose I take the RAID controller with disks from this machine and put it into an eServer 225 which has a Xeon CPU. Would everything work OK? -- Toomas Aas | [EMAIL PROTECTED] | http://www.raad.tartu.ee/~toomas/ * If Windows sucked, it would be good for something. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

There are Xeons build on the Coppermine core (the same as the P3), but if you are migrating to a newer type of Xeon (nocona, for instance) then you could run into problems. Even if your machine boots without problems, it will probably lead to reduced performance. After all, you compiled everything for a P3. Unless you don't have another choice, I would suggest you start over again and compile everything for your new Xeon.

Hi! Well, that depends on the type of Xeon. There are Xeons build on the Coppermine core (the same as the P3), but if you are migrating to a newer type of Xeon (nocona, for instance) then you could run into problems. Even if your machine boots without problems, it will probably lead to reduced performance. After all, you compiled everything for a P3. Unless you don't have another choice, I would suggest you start over again and compile everything for your new Xeon. The problem is, I could get this new machine without HDs, so the only option would be to move the RAID controller and disks over from the old server. And yes, this is P4 Xeon, so it's not the same core. (Somewhat) reduced performance is not my biggest concern. If I can bring the server up (even with reduced performance) then I can rebuild stuff as time permits. Actually, I was thinking, does the code that GCC 2.9.5 generates even make difference between CPUTYPE=p3 and CPUTYPE=p4 ? -- Toomas Aas | [EMAIL PROTECTED] | http://www.raad.tartu.ee/~toomas/ * One can never know for sure what a deserted area looks like. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
