MP in SUPERDOME

Hi All,

In a 128 way Superdome where we will have 2 cabinets, what about the no of MPs.

Will there be individual MPs for individual Cabinets ?

Thanks in advance,

Bond

No there will not.
Only one mp for the whole superdome.
This information can also be found in the manuals of the superdomes. A good admin must know how internet works and how to find this information instead of asking simple questions

Hi Mark,

I DID go thru documents,and there is a document in docs.hp.com which says

There is one MP per Superdome cabinet, thus there are two (2) for Superdome 64-socket. But one, and only one, can be active at a time. There is no redundancy or failover feature

Correct,

Only one mp a superdome there is no redundancy. You get an mp for the first cabinet. if you have 2 cabinets it's threated as one. So for a 128 superdome you get one mp to configure and no redundancy.
I thing it's better because i have seen many problems with the failover MP's on the other RP xxxx series.

grtz. mark

Hi Bond,

As stated you only need 1 MP for the entire complex.
Also remember you also need a Core I/O for *each* cell in the complex. If you have 4 cells across the 2 cabinets, you'll need 4 core I/O cards.

Re: MP in SUPERDOME

I'm sorry - not cell - I meant partition.
A partition can be comprised of 1 or more cells. And could be made up of an entire cabinet - even the entire complex.
Each individual partition needs at least one core I/O card.

Hi,

It is One and Only MP per COMPLEX,

A Complex is everything that is connected together, all cabinets,IOXs.

Re: MP in SUPERDOME

A IOX needed when you want to configure more than 4 npars in a complex, since the superdome cabinet has only 4 IO Chassis.

Hi Bond,

You will have only 1 MP per complex, you may have multiple cabinets( Superdome or IOX) and each having seperate UGUY's, but the MP will be only one.
Hope this clarifies.

Hi,

All Platform Management information from the different cabinets would be reporting to this MP.
