RED HAT EnTERPRISE LInux 6

Stable and trusted platform

Red Hat Enterprise Linux 6 is the sixth generation of a long-term, predictable operating plat-
form. With the flexibility to deploy on physical hardware, as a virtual host, as a virtual guest,  
or in the cloud, Red Hat Enterprise Linux 6 is the ideal foundation for next-generation data- 
centers. It ensures long-term stability while continuing to innovate and deliver enhancements —  
delivering the optimal combination of innovation and stability.

Key partnerships across the industry allow Red Hat to ensure the stability of the platform 
across the broad ecosystem of systems and applications. With embedded engineering and 
deep collaboration, Red Hat is on the forefront of the commercial maturation of technology. 

Customers benefit through the distribution of timely service packs and interim releases. The 
modular architecture of Red Hat Enterprise Linux allows functionality enhancements that do 
not effect application interfaces. Applications do not need to be rebuilt or recertified when they 
are updated because the application programming and binary interfaces (API/ABI) remain the 
same for the full life of a Red Hat Enterprise Linux release regardless of the physical, virtual, or 
cloud deployment model. This means that Red Hat’s rich ecosystem of thousands of certified 
applications are kept available, avoiding delays that would otherwise occur with expensive and 

time-consuming retesting efforts every time a vendor upgrades its software. 

Other features ensure that Red Hat Enterprise Linux is both scalable and trusted. Software 

RAID, storage multipath support, and network bonding provide resiliency in network and  
storage areas. File-system capabilities such as barriers and TRIM support allow for data safety  
and thin provisioning, while logical volume management provides disk abstraction. These are 
among the few features that have evolved to make Red Hat Enterprise Linux one of the most 
stable and trusted IT platforms.

Flexibility 

Red Hat Enterprise Linux offers customers a wide range of options for tailoring the operating 
system to their specific environments. Red Hat Enterprise Linux 6 includes new definitions of 
feature component groups to allow easy feature selection from a minimal install for a basic  
runtime environment, to a full set of feature selections including storage options, systems man-
agement, graphical interfaces, and administrative utilities. In addition to support for a breadth 
of infrastructure options, Red Hat Enterprise Linux 6 also includes a complete portfolio of open 
source applications. With supported applications ranging from web infrastructure to databases 
and development frameworks, Red Hat Enterprise Linux 6 installations are suitable for a broad 
range of workloads. 

In addition to feature flexibility, Red Hat Enterprise Linux also offers deployment flexibility,  
with support for a wide range of hardware from industry-standard servers to mainframes,  
and new subscription options for extending its lifecycle with Extended update Support (EuS) 
and Extended Lifecycle Support (ELS). 

Customers also get operational flexibility through automated deployment features such as  

the kickstart tools, automatic system updates, and auditing capabilities of Red Hat network. 
Red Hat network, and its on-premise version Red Hat network Satellite, helps organizations 
lower their per-system deployment and management costs, reduces unplanned downtime  
by automating and centralizing routine tasks, and creates a consistent environment.

CITIGROUP INNOVATES

There is a big push within Citi to 

drive IT optimization and con-

sistency. By delivering a com-

mon global Linux build across 

the enterprise, the firm has 

been able to retire a number of 

one-off infrastructure software 

products and their associated 

costs. In the process, it has been 

able to negotiate enterprise-level 

agreements for a reduced num-
ber of third-party products that 

can be leveraged across both 

hardware platforms. 

Additionally, virtualization has 

proven to be a successful strat-

egy for optimizing hardware 

utilization. IBM mainframes 

have a long tradition of deliver-

ing virtualization and perform 

especially well for workloads 

that require heavy input/output, 

whereas the value proposition 

for virtualization on x86 mainly 

comes from the low cost of entry 

and the ability to scale out mas-

sively. With a common Red Hat 

Enterprise Linux build, Citi is able 

to choose the virtualization that 

best meets its requirements.
