Dynamic Logical Partioning

Shivkumar — Sun, 31 Jul 2005 17:36:55 GMT

Dear Sir,

What is dynamic logical partioning in HPUX ?
I think only superdome servers has this facility for dynamic logical partitioning.

Please let me know what are the other server models which supports dynamic logical partitioning.

Thanks in advance!
Shiv

Dynamic logical partioning, (DLPAR) is a term from the AIX world, I think.

So no HP machine has this feature, including the superdome ;)

But partioning abilities are of course there, with the most full set of features in the keystone, matterhorn and superdome models.

DLPAR is from IBM, its not an hp product. The HP equalent is nPar & vPar. See below docs:

Hi Shiv,

Apart from superdomes all HPUx cell based systems supports partitioning. These includes RP74xx, RP84xx,RP5470 and even similar integrity models. Here is the best doc to be referred for this.

http://docs.hp.com/en/1705/oc.pdf

And here is the guide which also includes the suppoted hardware.

Npar is a hardware partition, while Npar is a software partition, think along the lines of vmware :). More than superdomes can run these two technologies in the HPUX unix line of servers. You can allocate resources between two vpar partitions in the same NPAR on the fly which can be usefull.
