Once upon a time, the saying was "Nobody ever got fired for buying IBM." Today, for Linux servers -- with all due respect to Canonical's Ubuntu and SUSE's SUSE Linux Enterprise Server (SLES) -- you can't get fired for running Red Hat's Red Hat Enterprise Linux (RHEL) on your Linux server. Today, Red Hat gave its customers more reason to stay the course with the release of RHEL 7.3,
This latest update to RHEL includes new features and enhancements built around performance, security, and reliability. The release also introduces new capabilities around Linux containers and the Internet of Things (IoT). From the top, here are the latest improvements:
RHEL 7.3 helps address the need for faster networking, with the addition of lightweight tunnels. These enable guest instances of RHEL 7.3 to be more secure, efficient, scalable, and flexible. Additionally, bulk packet memory allocator enhancements improve performance for both 40 and 100GB networking interfaces.
At the same time, high-transaction applications like databases, event processing, and virtual machines need improved input-output (IO) rates and lower latencies. New hardware technologies like non-volatile memory address these concerns, and RHEL 7.3 supports these next-generation memory devices. In addition, RHEL 7.3 makes performance-sensitive Parallel NFS (pNFS) clusters easier to manage, with support for the Block SCSI layout format and the Flex Files layout format.
