LBA in a HP Srever

Hi
I am trying to understand what an LBA is in a HP_UX Server.

Does LBA mean in simple term a PCI slot.

Please correct me.

Regards
Sagar

Do you have an Integrity or PA server?

Hi,
Normally SBA provides links to LBA which in turn connect to the PCI I/O slot.

Re: LBA in a HP Srever

Hi
Does this mean that if I've 8 PCI slots I'll have 8 LBA's?

Hi Sagar,

from
http://docs.hp.com/en/5185-6522/ch02s04.html

"A local bus adapter (the LBA, one for each PCI card slot in the chassis). The LBA connects its corresponding PCI card slot with the system bus adapter."
I am not sure it is same for all H/W like
PARISC/integrity/Superdome.

Re: LBA in a HP Srever

Thanks to all for their responses.

After I run through these respons I understand that for every PCI slot there is LBA which provides access to the SBA.

So if I want to create a vpar i can either specific the I/O address upto LBA or PCI slot.
Both would yield the same result.

Hope I've understood it properly
