By - Source: Red Hat

Last Friday, Raleigh-based Linux company, Red Hat, launched Enterprise Linux 6.5 (RHEL), the latest version of their flagship enterprise OS designed for those who build complex IT projects. The updated platform includes tools that aid in quickly tuning the system to run SAP applications based on published best practices from SAP. The release also includes a centralized certificate trust store that enables standardized certificate access for security services.

"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. The newest version of Red Hat Enterprise Linux 6 forms the building blocks of the entire Red Hat portfolio," says Jim Totton, vice president and general manager, Platform Business Unit, Red Hat.

The company announced that RHEL 6.5 includes OpenSCAP 2.1, which implements the National Institute of Standards and Technology's (NIST) Security Content Automation Protocol (SCAP) 1.2 standard. For financial institutions and trading-related industries, the update also adds sub-microsecond clock accuracy over the local area network (LAN) using the Precision Time Protocol (PTP). System admins can now inspect Internet Group Management Protocol (IGMP) data to list multicast router ports, multicast groups with active subscribers and their associated interfaces.

Red Hat points out that the platform's overall virtualization experience has also been improved. System administrators can now dynamically enable or disable virtual processors (vCPUs) in active guests. The handling of memory intensive applications on Red Hat Enterprise Linux guests has also been improved, the company reveals, with configurations supported for up to 4 TB 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," states the company press release. "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's news release also introduces RHEL's support for NVM Express (NVMe)-based SSDs, a spec that aims to standardize the interface for PCIe-based SSDs. Users can also now configure more than 255 LUNs connected to a single iSCSI target, and create debug (dump) files on systems configured with very large memory, such as 6 TB. The release even makes it easier to track and manage subscription consumption across the enterprise, integrating subscription tracking into existing business workflow.

"Red Hat Enterprise Linux 6.5 enables customers to deploy application images in containers created using Docker in their environment of choice: physical, virtual, or cloud," states the company press release. "Docker is an open source project to package and run lightweight, self-sufficient containers; containers save developers time by eliminating integration and infrastructure design tasks."
