"Largest Linux ever": Red Hat Enterprise Linux 6

Red Hat Enterprise Linux 6.2 (RHEL) has been launched week with a benchmark score which its developers insist proves the operating system’s validity for mission-critical enterprise computing environments.

RHEL has achieved the “largest multi-core Linux configuration results certified to-date” on the memorably named two-tier SAP Sales and Distribution standard application benchmark.

But what does that really mean?

The benchmark itself is apparently designed to test Red Hat Linux at “scale” and the SAP standard saw more than 22,000 users supported on a single system in this case.

Designed now to support multi-core processor technology, Red Hat Enterprise Linux 6 ran (and fully utilised) all 80 cores and 160 threads in an HP DL980 G7 8-processor system.

If you’re not familiar with the HP DL980 G7 server and don’t recall seeing one the last time you were in PC World, that’s because they start at US$38,130.

This test essentially represents (in Red Hat’s own words) “the largest Linux result submitted to SAP to-date”

Red Hat Enterprise Linux 6.2 is also said to deliver “significant improvements” in resource management and high availability, as well as new features aimed at storage and file system performance and identity management.

“Red Hat Enterprise Linux 6.2 provides additional capabilities to manage system resources. It also adds enhancements to storage and file system features including full support of iSCSI extension for RDMA. Now, benefits of low latency and high throughput through a standard SAN implementation based on 10Gb Ethernet are available to even the most demanding storage environments. This allows customers to opt out of expensive Infiniband hardware or other dedicated interconnect fabrics,” said the company, in a press statement.

This level of computing sees file system capabilities in use such delayed meta data logging, asynchronous and parallel file system writes, as well as support for multiple active instances of Samba in a cluster.

Development for Red Hat Enterprise Linux 7, the next major release of Red Hat Enterprise Linux is also “fully underway” at this time.
