of CPU errors). If a CPU is exhibiting excessive cache errors, HP-UX 11i version 2 will ONLINE activate to take its
place. Furthermore, the CPU cache will automatically be repaired on reboot, eliminating the need for a service call.

Memory: The memory subsystem design is such that a single SDRAM chip does not contribute more than 1 bit to
Memory
each ECC word. Therefore, the only way to get a multiple bit memory error from SDRAMs is if more than one
SDRAM failed at the same time (rare event). The system is also resilient to any cosmic ray or alpha particle strike
because these failure modes can only affect multiple bits in a single SDRAM. If a location in memory is "bad", the
physical page is de allocated dynamically and is replaced with a new page without any OS or application
interruption. In 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.

I/O
I/O
I/O: Partitions configured with dual path I/O can be configured to have no shared components between them,
I/O
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.

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 single
system availability configurable. Since no single system solution in the industry provides protection against a SPOF,
users that still need this kind of safety and HP's highest availability should use HA cluster software in a multiple
system HA configuration. Multiple HA software clusters can be configured within a single Superdome system (i.e.,
two 4 -ode clusters configured within a 32-way Superdome system).
