| Feature | Benefit |
| Unbreakable Enterprise Kernel | Includes: - Fast, modern, and reliable
- Tracks Linux mainline closely
- Able to parallelize network and disk IO
- Efficiently runs on systems with many cores and threads and NUMA nodes
- Optimized for solid state
- Includes latest Btrfs, OCFS2 file systems
- Built-in data integrity
- Hardware fault management
|
| Ksplice | - Enables zero downtime kernel updates
- Improves application availability, uptime, and security
- Enables the prompt installation of OS upgrades
- Improves sys admin productivity
- Easily integrates into your environment’s change management practices with rollback feature
|
| Btrfs | - Detects and fixes data and file system corruption
- Enables the creation of lightweight copies/clones of files or entire directory structures with minimal additional disk space requirements
- Improves backup operations
- Provides optimized support for solid-state (Flash) storage devices
- Allows quick rollback of software or OS upgrades
- Improves file system performance by reducing disk seeks
- Improves storage capacity and reduces disk I/O operations
- Provides integrated support for multiple devices
|
| OCFS2 | - Provides an open-source, enterprise-class alternative to proprietary cluster file systems
- Provides high performance and high availability
- Provides local file system semantics and can be used with any application
- Enables cluster-aware applications to leverage cache-coherent parallel I/O for higher performance
|
| Data Integrity | - Implements T10 PI and Data Integrity Extensions (DIX) to address silent data corruption
- End-to-end data protection prevents bad data from being written to disk
- Addresses the gap in logical block checksum checking that is not enough to prevent silent data corruption
- Addresses regulations such as Gramm-Leach-Bliley Act (GLBA), which mandates controls for the protection of customer data
|
| Linux Containers | - Enables running multiple instances of an OS or application on a single host
- Provides comprehensive process and resource isolation
- Enables you to run multiple versions of an OS on a single server
- Enables you to quickly set up a sandbox environment
|
| DTrace | - Provides a single view of the software stack
- Traces kernel, system libraries,and applications
- Enables you to quickly identify performance bottlenecks on production systems using dynamic tracing by defining probe points live, at runtime
- Enables static tracing using instrumentation compiled into kernel and applications
|
| Transcendent Memory | - Improves the utilization of physical memory in a virtualized environment by claiming underutilized memory in a system and making it available where it is most needed
- Provides fast pseudo-RAM of indeterminate and varying size that is useful primarily when real RAM is in short supply
