SUSE® has launched beta testing of SUSE OpenStack Cloud 6, giving customers an early look at the latest enterprise-ready technology for building Infrastructure-as-a-Service private clouds. Based on the OpenStack release Liberty, SUSE OpenStack Cloud 6 delivers high availability enhancements and non-disruptive upgrades along with Docker and IBM z Systems mainframe support to ease the transition of business-critical applications and data to the cloud. The Liberty-based beta will be demonstrated during this week's OpenStack Summit in Tokyo and at SUSECon in Amsterdam Nov. 2-6.
The openSuSE Linux 42.1 Leap Release Candidate 1 (whew, that was a mouthful) was made available on their download page yesterday (click on 'switch to Development Version' at the top of the page to get it). Although I will be running their Tumbleweed advanced development version on most of my computers, I am planning on keeping Leap on one or two of them, so I have been downloading and trying the pre-releases as Leap development has progressed.
Leap is less about the newest updates, which is the purpose of Tumbleweed and its frequent snapshots; Leap is more about relevance and purposeful updates and packages that provide users prolonged, stable and enterprise-level functionality. Leap has newer, community packages built on core SUSE Linux Enterprise (SLE) source code for a more stable base. Of the 7,000-plus packages in Leap, 1,500 are from SLE.
Besides Oracle Linux, OpenSUSE and SUSE Linux Enterprise Server were among the first tier-one Linux distributions really backing the Btrfs file-system. SUSE has liked Btrfs for years and at last week's LinuxCon Europe 2015 in Dublin there was a presentation on their use of Btrfs with handling system rollbacks.
Earlier this week I posted a number of openSUSE Leap benchmarks of their different kernels: debug, default, desktop, and vanilla. Here's some follow-up tests with more results from comparing the openSUSE 42.1 Leap Beta kernel builds.
The tests are very similar to the article earlier this week, just with many more data-points now after seeing the performance differences from the initial test suite.
Those unfamiliar with the openSUSE kernel flavors can see this Wiki page. Tested for this article was the default, desktop, debug, and vanilla kernel options. During testing, installed by default was the -desktop kernel when installing the openSUSE 42.1 Leap Beta and thus that was what ended up being used in last week's Linux distribution comparison, although the Wiki page indicates that the -default kernel should be the default for desktops and servers. The 4.1.6-10 kernel was used when testing the -debug, -default, -desktop, and -vanilla kernel images obtained from the official openSUSE Leap repository.
RapidDisk is an advanced Linux RAM Disk which consists of a collection of modules and an administration tool. Features include: Dynamically allocate RAM as block device. Use them as stand alone disk drives or even map them as caching nodes to slower local disk drives.
I pushed 3.4 into the mainline earlier this morning. Changes include:
