SUSE announces live kernel patching, storage solution Featured


Live patching of the Linux kernel in the recent enterprise release of SUSE Linux (SLES) will from now on be available to all and sundry.

At the time of release, the technology, kGraft was available in the kernel but needed kernel module packages to be produced, tested and delivered. That has now been completed.

The announcement was made on Tuesday at SUSECon 2014, the company's third annual conference which is being held in Orlando, Florida, this week.

Matthias Eckerman, senior product manager for SUSE, was quoted in a media release as saying: "In addition to increasing service availability by updating critical kernel patches without rebooting, and reducing the need for planned downtime by patching frequently, SUSE Linux Enterprise Live Patching preserves security and stability by applying up-to-date patches.

"It's a fully open source solution that features zero-interruption interaction with the system and a familiar deployment method. It's ideal for mission-critical systems, in-memory databases, extended simulations or quick fixes in a large server farm."

In contrast to some other methods of live patching, the SUSE solution does not require the stopping of the whole system while patching is in progress.

In another announcement, SUSE said it had begun beta testing of a self-healing, self-managing, distributed software-based storage solution for its business customers. Called SUSE Storage, it uses off-the-shelf disk arrays.

The system is based on the Firefly version of the Ceph open source project and includes cache tiering, thin provisioning, remote replication, copy-on-write cloning and erasure cloning.

The company also said that customers who wanted to use their subscriptions in the public cloud could transfer them to a SUSE Certified Cloud provider to deploy new workloads or transfer existing workloads. There is no additional cost and an existing support relationship can be utilised.

In another development, SUSE has thrown its support behind SAP Startup Focus, a global program to help startup companies in the big data, predictive and real-time analysis space to develop new applications that use the SAP HANA platform.

As part of this, qualified startups would be entitled to receive a comprehensive developer version of SAP HANA on SLES as a downloadable virtual machine free for six months. Free training will also be made available via SUSE's Certified Linux Administrator Academy.
