2: Itanium 2 requires Red Hat Advanced Server for the Itanium processor.
All products in the Red Hat Enterprise Linux family are based on a common software core--kernel, libraries, development toolchain. This provides a homogeneous environment ideal for simplifying multi-system and client-server configurations. The immediate benefit: Red Hat Enterprise Linux applications run seamlessly and system management procedures are standardized across the entire family.
While the supported capabilities of individual Red Hat Enterprise Linux products are focused on each product's specific role, features common to all include:
- Asynchronous I/O support: Applications no longer need to pause after issuing read I/Os until they are complete.
- Increased SMP granularity: Particularly in the SCSI I/O subsystem. Permits increased I/O throughput in SMP systems with multiple I/O adapters.
- SMP Scheduler enhancements: Support process-CPU affinity. Improves performance by increasing the CPU cache hit-rate and greatly reducing spinlock contention in SMP systems.
- Bounce Buffer Elimination: Drastically reduces I/O-related memory copy operations in large memory systems (>1GB memory).
- LSB (Linux Standard Base) interface conformity: Supports the industry-wide Linux API standard.
- Multiple enhancements to improve database performance
Enterprise-focused release cycle
Red Hat Enterprise Linux family products have a release cycle specifically designed to provide a stable platform for all phases of an enterprise IT deployment. Major Red Hat Enterprise Linux releases will occur approximately every 12-18 months. This allows ISVs to focus on a common, stable platform and customers to effectively plan migration and upgrade cycles.

Enterprise-class support
Red Hat Enterprise Linux products include a full year of support services with varying service levels depending on your chosen subscription option.
In addition, two support upgrades are available: Developer Support and Technical Account Management. Both provide more in-depth technical services.
Red Hat Enterprise Network
Red Hat Enterprise Linux products include one full year of Red Hat Enterprise Network's Software Update module, a service that provides fine-grained management and control capabilities that scale to thousands of Red Hat Enterprise Linux systems. Features include:
- System grouping and management
- System comparisons
- Role-based system administration support
- Enhanced system details
Also available for Red Hat Enterprise Linux systems is Red Hat Enterprise Network's System Management module, which provides comprehensive monitoring of the operating system and targeted applications (such as Oracle, MySQL, and BEA WebLogic).
