54 SYSTEM MANAGEMENT AND FEATURES 27 RED HAT ENTERPRISE LINUX 7 FEB 2015

55 NETWORK MANAGEMENT NetworkManager Easy to use yet comprehensive network management suite designed to provide painless network configuration. Flexible interface options with GUI, (new) CLI, and (new) TUI for managing local, remote, or even headless systems. Supports a broad array of many common network interface types, including: 28 Eliminates the need to manually edit network configuration files by hand. Ethernet, IPoIB, VLANs, Bridges, Bonds, Teams, WiFi, WiMAX, WWAN, Bluetooth, VPN, and ATM-based DSL.

56 NETWORK FEATURES Team Driver Mechanism for bonding multiple network devices (ports) into a single logical interface at the data link layer (L2) Alternative to the existing Linux Bonding driver Provides an increase in maximum bandwidth and link redundancy Provides a number of advantages over traditional bonding while providing equal or even slightly better performance in some cases. Implemented mostly in user space with only the necessary data fast-paths in the kernel. Moves most of the work and logic into a user space daemon making it: more stable easier to debug much simpler to extend eth0 Server Server team0 eth1 29 Network Network Switch Switch

57 NETWORK FEATURES 40G Ethernet (IEEE 802.3ba) Support for 40G Ethernet link speeds enabling faster network communication for applications and systems. Highly accurate network time synchronization using: Precision Time Protocol (IEEE 1588v2) Enables faster clock synchronization with better accuracy than ntpd especially in cases where network connectivity is not always constant. Numerous TCP optimizations and enhancements aimed at reducing overall latency for connection oriented services such as web servers, including: 30 Capable of achieving clock accuracy in the sub-microsecond range when used in conjunction with PTP hardware support. Chrony Method for precisely synchronizing distributed clocks. Fast Open, Tail Loss Probe (TLP) Algorithm, Early retransmit (ER), Proportional Rate Reduction (PRR), Busy Poll (Low Latency Sockets)

58 SECURITY FEATURES New dynamic and protocol independent firewall service, firewalld, provides greater flexibility over traditional iptables. Eliminates service disruptions during rule updates. Supports different network trust zones for per-connection firewall settings. 31 Unified firewall management service for IPv4 (iptables), IPv6 (ip6tables), and Ethernet Bridges (ebtables). Simple yet powerful XML-based configuration file format with nearly 50 built-in pre-defined settings for many common system services. Easier analysis of log files with the help of structured logging that provides additional context in the logs. Extension of SELinux access controls to NFS with the help of labeled NFS.

63 EASE OF USE: CHOICE OF DESKTOPS KDE V RED HAT ENTERPRISE LINUX 7 FEB 2015 AN ALTERNATIVE TO GNOME FOR USERS WHO PREFER KDE

64 DEVELOPER FEATURES Build and concurrently install multiple versions of custom software using scl-utils. Access to updated versions of compilers, debuggers, and related tools (gcc-4.8, gdb-7.6, etc.), providing enhanced support for parallelism and concurrency and extensive new optimizations. Support for the latest version of Java with OpenJDK 7 37 To profile and compare performance across multiple JVMs, users can now install different minor versions of Java 7 (e.g. OpenJDK7 u40 and OpenJDK7 u45) in parallel, with the default version selectable through alternatives.
