Before install subracks in the cabinet, you may read the following instruction to learn how to install Huawei OSN 3500 subrack into the cabinet correctly.

Installation of Huawei transmission network equipments is very essential. Here express how to install into the cabinet and remove the subrack, follow the procedure of installation into cabinet in the reverse order.

First, you must observe the subrack and ensure that installing position of the mounting ears to match the cabinet, so the Huawei OSN 3500 subrack can be installed into the cabinet by mounting ears which are installed in the holes for the mounting ears of the N63E cabinet. Please note that you must install the subrack in the lower part of the cabinet first, and then install the subrack in the upper part of the cabinet. If only one subrack is required, you may install it in the lower part of the cabinet. In addition, figure 20-3 shows the position of the subrack in the 2200mm-high cabinet.

After guaranteed the position of subrack, then we can install the subrack into the cabinet.

First of all, the subrack must be transported to the site. Secondly, what tools and materials you need to prepare are common tools and panel srews.

Thirdly, installation procedure:

Step 1 Place the subrack along the guide rail and insert it in slowly.

Step 2 Use panel screws to fix the subrack to the front column of the cabinet through the holes on the mounting ears.

Here please note, if multiple subracks share one cabinet, it is recommended that you install the lower subrack before installing the upper subrack.

After finishing the Huawei OSN subrack installation, you may check the following several necessary items. First, you must check that whether the subrack is installed at the correct position, that’ll affect the following installation. Secondly, close the front door of the cabinet and ensure that the subrack does not contact the front door. Thirdly, blank panels are inserted in the idle slots of the subrack.

After checked the installation of subrack, then, you can begin to install boards.

CD Audio Grabbers

CD audio grabbers are designed to extract (“rip”) the raw digital audio (in a format commonly called CDDA) from a compact disc to a file or other output. This type of software enables a user to encode the digital audio into a variety of formats, and download and upload disc info from freedb, an internet compact disc database.

Is copying CDs legal? Under US copyright law, converting an original CD to digital files for personal use has been cited as qualifying as ‘fair use’. However, US copyright law does not explicitly allow or forbid making copies of a personally-owned audio CD, and case law has not yet established what specific scenarios are permitted as fair use. The copyright position is much clearer in the UK. From 2014 it become legal for UK citizens to make copies of CDs, MP3s, DVD, Blu-rays and e-books. This only applies if the individual owns the physical media being ripped, and the copy is made only for their own private use. For other countries in the European Union, member nations can allow a private copy exception too.

18 New Open Source Projects in the 2015 Guide to the Open Cloud

January 23, 2015

Open cloud paper The Linux Foundation this week released its second annual Guide to the Open Cloud, which profiles the open source projects that organizations are using to build their own open clouds from the ground up. This year’s paper includes many new projects – 18 in total – and two additional technology categories that have become increasingly more relevant in the past year.

Taking a look at the projects that were added, and why, can help shed some light on the trends and technologies that are shaping the cloud. Projects such as LXC, CoreOS, OSv, Apache Mesos, Apache Stratos, Deis, and Kubernetes grew along with the need and opportunity for new platforms and management tools around Linux container technology, and/or specialized operating systems built for web-scale IT and mobile computing.

The increasing maturity of cloud storage is also visible in this year’s guide, with additions such as Apache Cassandra, CouchDB, MongoDB, Redis, and Swift. Many of these projects are far from new but are now successfully making the transition to the cloud and scale-out computing in new and interesting ways.

Then there are the projects such as Ansible and ManageIQ that are relatively new challengers or supplements to popular configuration tools such as Puppet and Chef that arise out of the increasing adoption of hybrid clouds and the subsequent need to manage them.

And finally the paper adds a whole new category of projects around software-defined networking and network functions virtualization with profiles on OpenDaylight, Open vSwitch and Open Contrail. This is still a very new area of the cloud – so new that some projects are just now starting to see production deployments. But SDN adoption among service providers and carriers is widely expected to rise in coming years as IT departments look for increasing flexibility and scalability in the cloud.

Below are the 17 new projects by category in the 2015 Guide to the Open Cloud. For the full list in each category, along with project profiles, download the report.

New to the cloud report this year

Hypervisor and container

LXC – Lightweight virtual machines enabled by functions within the Linux kernel, including cgroups, namespaces and security modules. Userspace tools coordinate kernel features and manipulate container images to create and manage system or application containers.

Cloud Operating Systems

Apache Mesos – an open source cluster management tool also described as an operating system kernel for the data center.

CoreOS – A lightweight Linux distribution designed for running large-scale cluster deployments. Applications run inside of containers to isolate them from the operating system.

OSv – OSv is an open source cloud operating system designed to run a single application on top of a hypervisor.

Platform-as-a-Service

Apache Stratos – an open source enterprise PaaS framework that helps run Apache Tomcat, PHP, and MySQL applications.

Deis – Deis is an open source PaaS that builds upon Docker and CoreOS to provide a lightweight PaaS with a Heroku-inspired workflow.

Provisioning and Management Tool

Ansible – open source cloud automation software for application deployment and configuration management on multi-tier architectures.

Kubernetes -an orchestration and management tool for Docker container clusters.

ManageIQ – a hybrid cloud management tool to manage services running on cloud and virtualization platforms.

Storage

Apache Cassandra – a highly scalable, eventually consistent, distributed, structured key-value store.

CouchDB – a distributed document database system.

MongoDB – a high performance document database.

Redis – an open source key value cache and store.

Swift – a highly available, distributed, eventually consistent object store.

SDN and NFV projects

OpenDaylight – an open source platform for network programmability to enable SDN and NFV. The software components include a fully pluggable controller, interfaces, protocol plug-ins and applications.

Open vSwitch – an open source virtual switch designed to enable massive network automation while still supporting standard management interfaces in distributed computing.

OpenContrail – an open source software-defined networking project that provides all the necessary components for network virtualization including an SDN controller, virtual router, analytics engine, and published northbound APIs.

If you want a Linux on a laptop, it’s easy to install it yourself. You can also always buy one from a specialized Linux vendor such as System76 and ZaReason or even get a mainstream laptop, like the new Dell XPS 13 and 15 with Ubuntu installed. What you can’t do is get one with a minimum of proprietary firmware, until now.
