HP-UX Virtual Partitions 6.0 Release Notes

Embedded LORA functionality
The vPars v6.0 VSP comes with embedded Locally Optimized Reference Architecture (LORA)
functionality that automatically assigns the best available resources (CPU and memory) to an
activating vPar. The vPar commands are simplified to only accept a count for CPU and size for
memory when assigning resources.
Hyperthreading enabled for high overall performance
Hyperthreading is a server-wide setting. vPars v6.0 sets hyperthreading to enabled. To control the
logical CPU setting of individual vPars, you must set the dynamic tunable lcpu_attr using the
kctune command in the vPar itself.
Supports N_Port ID Virtualization (NPIV)
vPars v6.0 supports NPIV to allow SAN storage access and manageability from within the vPar.
Unlike other forms of storage on vPars v6.0, LUNs under NPIV are not visible to the VSP or any
other vPar. For information about configuring NPIV, see the NPIV whitepaper HP-UX vPars 6.0
N-Port ID Virtualization (NPIV) and the HP-UX Virtual Partitions v6.0 Administrator Guide.
Shared I/O resources
vPars v6.0 presents a reference platform that is composed of a single cell that contains all the CPU
cores and memory assigned to the vPar and connection to 8 PCI buses that can be populated with
I/O devices assigned to the vPar. Each PCI bus has 8 available device slots that can be assigned
an HBA or NIC. An available I/O storage target (such as those backed by files, logical volumes
or LUNs) can be added to the vPar if a target is available on the device. If the device is full and
a new adapter needs to be created, the vPar must be brought down to create a new adapter.
More virtual partitions per server or blade
vPars v6.0 allows you to create more virtual partitions than in prior versions of vPars because of
the finer I/O granularity. Other internal resource limits have been addressed to support up to 31
vPars on the BL890c i2 server.
