Power7+ Ras Features - IBM Power 750 Technical Overview And Introduction

either the Internet (HTTPS or VPN) or modem, and can be configured to communicate
securely through gateways to provide customers a single point of exit from their site.
Communication is one way. Activating Electronic Service Agent does not enable IBM to
call into a customer's system. System inventory information is stored in a secure
database, which is protected behind IBM firewalls. It is viewable only by the customer and
IBM. The customer's business applications or business data is never transmitted to IBM.
More accurate reporting
Because system information and error logs are automatically uploaded to the IBM support
center in conjunction with the service request, customers are not required to find and send
system information, decreasing the risk of misreported or misdiagnosed errors.
Once inside IBM, problem error data is run through a data knowledge management
system and knowledge articles are appended to the problem record.
Customized support
By using the IBM ID you enter during activation, you can view system and support
information by selecting My Systems at the Electronic Support website:
http://www.ibm.com/support/electronic
My Systems provides valuable reports of installed hardware and software by using
information collected from the systems by Electronic Service Agent. Reports are
available for any system associated with the customers IBM ID. Premium Search
combines the function of search and the value of Electronic Service Agent information,
providing advanced search of the technical support knowledgebase. Using Premium
Search and the Electronic Service Agent information that has been collected from your
system, your client are able to see search results that apply specifically to their systems.

4.5 POWER7+ RAS features

This section lists POWRE7+ RAS features in this release:
Power-On Reset Engine (PORE)
Enables a processor to be re-initialized while the system remains running. This feature will
allow for the Concurrent Firmware Updates situation, in which a processor initialization
register value needs to be changed. Concurrent firmware updates might be more
prevalent.
L3 Cache dynamic column repair
This self-healing capability completes cache-line delete and uses the PORE feature to
potentially avoid some repair actions or outages that are related to L3 cache.
Accelerator RAS
New accelerators are designed with RAS features to avoid system outages in the vast
majority of faults that can be detected by the accelerators.
Fabric Bus Dynamic Lane Repair
POWER7+ has spare bit lanes that can dynamically be repaired (using PORE). This
feature avoids any repair action or outage related to a single bit failure for the fabric bus.
