Technical Highlights


GA Dec 2013

RHEL on Power Features
• Performance enhancements

• Updated Drivers

• More Stable

SR-IOV support cleanup for Power
Fix-up the SR-IOV code to be more stable
End users expect their PCI devices that support SR-IOV to function correctly both in dedicated (PF) and
virtualized (VF) modes.
AddVDSO version of getcpu
Customers will see in improvement in sched_getcpu times from 300+ns down to about 30ns. Customers
will see improvements in gettimeofday times from 60ns down to about 9-17ns.

Highlighted Features

Update mlx4 drivers to support new Mellanox RoCE adapter on Power
Update the mlx4_en and mlx4_ib drivers to support a new 40Gb ConnectX3-EN based two port RoCE
adapter on Power
Support the Power I/O roadmap
Update sfc driver with EEH support and Power performance optimizations
Update the sfc driver to pick up EEH support as well as numerous performance enhancements that were
developed for Power. Increases single port performance by 3x
Support the Power I/O roadmap. Provides critical performance and RAS enhancements for Power
customers with Solarﬂare adapters.


Improve logging when crashkernel=auto can't be satisﬁed
Currently, the RH kernel sometimes removes crashkernel=auto in yaboot.conf from the kernel command-
line at run-time.

!
The kernel parses only the last crashkernel= entry, and if it's set to auto, asks the arch code what the size
of the crashkernel region needs to be, based upon system memory size.
End-users are recommended to pass crashkernel=auto on the kernel command-line for RAS purposes.
However, the minimum LPAR size is less than 8G and thus RAS is not always possible with =auto.
Customers would expect to be informed if no dumps are possible on their LPAR.

Security


File Systems - Many choices


Linux Containers - Application isolation
Application isolation mechanism for light-weight, multi-tenancy environments with a single
underlying OS

Software packaging concept that typically includes an application and all of its runtime
dependencies.

!
• Easy to deploy and portable across host systems

• Isolates applications on a host operating system

• In RHEL, this is done through:

• Control Groups (cgroups)

• kernel namespaces

• SELinux, sVirt

Linux Containers - Benefits and Key Elements


Linux Containers enables continuous delivery


Windows Interoperability
• Out-of-the-box Linux support of direct interoperability with Active Directory

• Automatic detection of the domain controller to join (AD/IDM)

• Simple, integrated set-up of the authentication configuration

•MariaDB replaces MySQL

!
•YUM - download in parallel

!
•Journald

•less /var/log/message -> journalctl

•tail -f /var/log/message -> journalctl -f

!
•Subscription-manager only (rhn_register only registers to RHN Satellite)

•Red Hat Subscription Manager is installed on a local system and it tracks what products are installed, what
subscriptions are available for the system, and what subscriptions are actually used by the system. It also tracks
subscription expirations and automatically attaches new subscriptions based on the products and hardware.

Other new features

For a complete list of customer success stories please access: http://people.redhat.com/fmiranda/powersystems/customer_references/

The need:

While running its two disparate Power Systems, Retraites Populaires was not able to leverage
the requisite flexibility and on-demand capacities to allow for a smooth evolution towards new
technologies while keeping the existing systems running. Moving forward, the company wanted
more functionality and power from its IT infrastructure.

!
The solution:

Working with IBM®, Retraites Populaires implemented two Power 770 systems running i and
Linux – Red Hat, which allowed the company to have a homogenized Power architecture and
gain the needed technology and capacity to implement its IT strategy.The two systems ensure
high availability, thereby negating performance penalties for the end-users.

!
The benefits:

Consolidated the hardware and software investments to lower theTCO

Performed smooth evolution of IBM i system architecture to modern Power 7 architecture

Increased flexibility with the exploitation of the virtualization technologies offered by the Power
architecture
Gains greater overall functionality while powering up its IT infrastructure
