ENTERPRISE LINUX VENDOR Red Hat has released Red Hat Enterprise Linux (RHEL) 6.3 that offers improved virtualisation capabilities.
Red Hat's RHEL operating system has enjoyed considerable success in businesses and the firm has been churning out minor updates to RHEL 6 over the last 18 months. RHEL 6.3 concentrates on improving virtual CPU and RAM limits for virtual machines and includes OpenJDK 7.
Red Hat has also packed a number of software and driver updates into RHEL 6.3, including GCC optimisations for Intel's Xeon E5 processor. The firm also highlighted support for two-factor authentication and AES-CTR encryption in OpenSSH.
However Red Hat is keen to promote the work it has done in improving RHEL as a virtual machine host. The firm said that RHEL 6.3 supports 160 virtual CPUs, while memory capacity for KVM guests has increased to 2TB.
Red Hat is facing competition from Canonical with its Ubuntu Linux distribution, however RHEL has been steadily building up a head of steam for a number of years now and can be found in a number of blue-chip organisations. Red Hat is also preparing for its annual Red Hat Summit next week, where it is expected to talk about its efforts in the burgeoning ARM server market.
As Red Hat was preparing its RHEL 6.3 announcement, the CentOS team tweeted that it had already started building SRPMs, strongly suggesting that a free version of RHEL 6.3 might not be too far away. µ
