RADs

Hi,

How I could know the number of RADs that I have in a system?.
I have a GS320.

Thanks!,
Carmen.

Re: RADs

Carmen,

You can try with "sched_stat -R"

or you can write a C-program.
Look for an example in the manpage of rad_get_info

Hope this helps

Re: RADs

Hi Carmen,

I use "vmstat -R" which shows the number of RAD's and associated per RAD statistics.

Hi,

If I have this:

vmstat -R
Virtual Memory Statistics: (pagesize = 8192)
procs memory pages intr cpu

Re: RADs

Hi Carmen,

Yes, you have 1 RAD configured on your GS320.

RAD is the software version of a QBB (Quad Building Block) in a Wildfire system. Each QBB can contain 4 CPU's.

A GS320 system will generally have 8 QBB's, with each QBB potentially containing a maximum of 4 CPU's (8x4=32 i.e. GS320). Now that's the potential provided we built 1 system out of this hardware. You can hardware partition the GS320 on QBB boundaries in to some combination of systems not exceeding 8.

I would expect to find that your system has 4 CPU's knowing you have 1 RAD. To see this you can use "pinfo" command, or sched_stat referenced earlier.

NOTE: The "sched_stat -R" command I believe was introduced in V5.1B.

So, maybe your GS320 has been hardware partitioned in to more than 1 system.

If your findings differ that what I've layed out above, please provide teh "sched_stat" output and OS version (sizer -v").

Hope this helps,
Dave Bechtold
