Concurrent Dump is a new feature for HP-UX 11i v3 crash dump
subsystem. This feature enhances performance scalability of the
HP-UX crash dump subsystem with machine configuration if the customer
follows recommended guidelines for dump device configuration. This
solution is implemented for Itanium®-based
platforms only.
Summary
of Change |

What’s
New for Customers Migrating from HP-UX 11i v1 September 2005?
This is a new functionality for HP-UX 11i v3, but it is only
available for customers who will be migrating to Itanium®-based platforms. Using this
functionality, you can configure your machine to perform a distributed
parallel dump, thereby improving the dump throughput and reducing
dump time.
HP-UX 11i v3 crash dumps can be done faster compared to HP-UX
11i v1 running on the same machine. This speed improvement can be
seen only on HP Itanium®-based platforms.
What’s
New for Customers Migrating from HP-UX 11i v2 June 2006?
This is a new functionality for HP-UX 11i v3. Using this functionality,
you can configure your machine to perform a distributed parallel
dump, thereby improving the dump throughput and reducing dump time.
HP-UX 11i v3 crash dumps can be done faster compared to HP-UX
11i v2 running on the same machine. This speed improvement can be
seen only on HP Itanium®-based platforms.
