Red Hat's Latest Version of Enterprise Linux Includes Enhanced Admin and Storage Tools

Red Hat, Inc., a provider of open source solutions, has begun shipping a new version of Red Hat Enterprise Linux which includes additional networking enhancements to help provide system administrators a more detailed view of network activity.

The new release, Red Hat Enterprise Linux 6.5, “provides the innovation expected from the industry’s leading enterprise Linux operating system while also delivering a mature platform for business operations, be it standardizing operating environments or supporting critical applications,” said Jim Totton, vice president and general manager for Red Hat's Platform Business Unit. “The newest version of Red Hat Enterprise Linux 6 forms the building blocks of the entire Red Hat portfolio, including OpenShift and OpenStack, making it a perfect foundation for enterprises looking to explore the open hybrid cloud.”

New capabilities enable sysadmins to inspect IGMP (Internet Group Management Protocol) data to list multicast router ports, multicast groups with active subscribers and their associated interfaces, all of which are important to many modern networking scenarios, including streaming media.

Red Hat Enterprise Linux 6.5 also enables sysadmins to dynamically enable or disable virtual processors (vCPUs) in active guests for elastic workloads. The handling of memory intensive applications as Red Hat Enterprise Linux guests has also been improved, with configurations supported for up to 4TB of memory on the Kernel-based Virtual Machine (KVM) hypervisor.

The KVM hypervisor also integrates with GlusterFS volumes to provide direct access to the distributed storage platform, improving performance when accessing Red Hat Storage or GlusterFS volumes. Finally, guest drivers have been updated to improve performance of Red Hat Enterprise Linux 6.5 running as a guest on supported third-party hypervisors.

Red Hat Enterprise Linux 6.5 also includes a solid-state drive (SSD) controller interface, introducing support for NVM Express (NVMe)-based SSDs. Also, it is now possible to configure more than 255 LUNs connected to a single iSCSI target. In addition, control and recovery from SAN for iSCSI and Fibre Channel has been enhanced, and updates to the kexec/kdump mechanism now make it possible to create debug (dump) files on systems configured with very large memory (e.g., 6TB).
