hardware differences

[Rick Garland]

Hi all:

Got a 2 node cluster that has HPUX 11.00 & SG 11.14.

1 node is a N4000-55 with CPU of PA 8600. The other node is a N4000-44 with CPU of PA 8500.

Are these hardware differences enough to cause problems with ServiceGuard?

Thanks!

No, not at all. SG woudn't really know, nor care.

No they are not.
You can for example have an L class, a K-class and a V-class all in the same cluster.
The only issues come down to having enough resoyrces to run the appliactions when the packages ar eactive on the node.

Hi Rick,

there won't be problems due to hardware differences.

[Florian Heigl (new acc)]

Nope :)

The 550 and 440 MHz CPU models are virtually the same, and even MC/SG clusters with ia64 and hppa2.0 are said to work fine.

Rick - nice to see your new hat!

Hardware is fine...as others have said - you can even mix classes...
