We just received a pair of GS160's with two AC input boxes in the power cab.
The GS160 also came with an expansion cab with two PCI boxes.
I have a couple of questions on the configuration and would like to see if
anyone else has had the same.
1) We have created two hardware partitions on the boxes. Partition 0 will
have QBB 0 and QBB 1 and partition 1 will have QBB 2 and QBB 3. Each
partition has a Master PCI and one extra PCI box.
After doing some testing we discovered that both of these partitions are
connected to the same AC input box. If we follow the diagram and the color
codes in the power cab the machine is cabled correctly. Is there any reason
why a GS160 doesn't use both AC input boxes? One of the AC boxes has only a
PCI box on it. All the DC supplies are plugged into the bottom one. It seems
the other AC input box is reserved for an upgrade to a GS320. Since I'm
using hardware partitioning I would like to separate the AC input boxes so
that each one could go to a separate UPS. That way if a UPS fails or needs
to be shut down it would only effect one of the partitions.
2) PCI boxes. Is there a way to control the power to each partitions PCI
boxes independent of the other partition? I needed to move a ethernet card
in partition 1's PCI box and when I did a power off -partition 1 at the SCM
the power remained on the PCI box. I then unplugged the PCI box and the
other partition crashed.
It seems that the CPU and memory can be partitioned and in fact the PCI's
are only connected to the QBB's in that partiton, but if you need to move
cards or add cards to either partitions PCI the whole machine needs to be
powered down.
We are trying to set up two separate clusters between two partitioned
GS160's and would like to have the capability of shutting one partition down
and replacing a fail PCI card if that should happen without effecting the
other partition. Can I do this?
