Type/Severity
Product Enhancement Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
Updated Red Hat Enterprise MRG Realtime packages that add enhancements are now
available for Red Hat Enterprise MRG 2.2 for Red Hat Enterprise Linux 6.
Description
Red Hat Enterprise MRG (Messaging, Realtime, and Grid) is a next-generation IT
infrastructure for enterprise computing. MRG offers increased performance,
reliability, interoperability, and faster computing for enterprise customers.
MRG Realtime provides the highest levels of predictability for consistent
low-latency response times to meet the needs of time sensitive workloads. MRG
Realtime provides new levels of determinism by optimizing lengthy kernel
codepaths to ensure that they do not become bottlenecks. This allows for better
prioritization of applications, resulting in consistent, predictable response
times for high-priority applications.
This update adds the following enhancements:
- With this update, MRG Realtime introduces the libibverbs-rocee and
libmlx4-rocee packages to provide high performance networking. The
libibverbs-rocee package provides a library to enable user space processes to
use the RoCE (RDMA over Converged Ethernet) "verbs" API according to the
InfiniBand Architecture Specification and the RoCE Protocol Verbs Specification.
The libmlx4-rocee package provides a device-specific driver for Mellanox
ConnectX InfiniBand host channel adapters (HCAs) for the libibverbs-rocee
library. (BZ#798426, BZ#798427)
Users of the Realtime capabilities of Red Hat Enterprise MRG 2.2, which is
layered on Red Hat Enterprise Linux 6, are advised to upgrade to these updated
packages, which add these enhancements. Note that the system must be rebooted
for this update to take effect.
