Configuration
addition, a combination of hardware and software scrubbing is used for memory. The software
scrubber reads/writes all memory locations periodically. However, it does not have access to
"locked down" pages. Therefore, a hardware memory scrubber is provided for full coverage.
Finally data is protected by providing address/control parity protection.
Memory DRAM fault tolerance, i.e. recovery of a double SDRAM failure
DIMM address / control parity protection
Dynamic memory resilience, i.e. page de allocation of bad memory pages during
operation.

NOTE:
NOTE: Dynamic memory resilience is not supported when running Windows Server 2008,
SUSE SLES 9,r Red Hat RHEL AS 3, or OpenVMS in the partition.

NOTE:
NOTE: Cell ICAP is not supported when Windows Server 2008, SUSE SLES 9 or 10, RHEL
AS 3 or 4, or OpenVMS V8.2 1 is running in the partition. Cell iCAP support is available
with OpenVMS partitions starting with OpenVMS V8.3.

I/O
I/O: Partitions configured with dual path I/O can be configured to have no shared components
between them, thus preventing I/O cards from creating faults on other I/O paths. I/O cards in
hardware partitions (nPars) are fully isolated from I/O cards in other hard partitions. It is not
possible for an I/O failure to propagate across hard partitions. It is possible to dynamically repair
and add I/O cards to an existing running partition.

applications between hardware partitions (nPars) on a single Superdome system. All providers of
mission critical solutions agree that failover between clustered systems provides the safest
availability-no single points of failures (SPOFs) and no ability to propagate failures between
systems. However, HP supports the configuration of HA cluster software in a single system to allow
the highest possible availability for those users that need the benefits of a non-clustered solution,
such as scalability and manageability. Superdome with this configuration will provide the greatest
