3. A VCF subscription offering will be available in Q1 as part of the new VMware Cloud Universal program, with pricing and details to be announced later.
C-mode refers to an OS mode in ONTAP 8.0 and beyond where two or more controllers operate as a single shared resource pool. In c-mode, volumes can span multiple storage systems and clients see a single global namespace rather than individual shares. Key features of c-mode include non-disruptive operations where volumes can be moved between nodes and aggregates transparently, with no change to the client view of the filesystem. The major commands for storage failover in c-mode are 'storage failover giveback' to return ownership and 'storage failover show' to check the status of aggregates.

The document provides a history of the Linux operating system in three main parts:
1. Richard Stallman founded the Free Software Foundation in 1985 in response to companies restricting the sharing of software code. This led to the creation of the GNU operating system project.
2. In 1990, Linus Torvalds created the Linux kernel based on Andy Tanenbaum's Minix operating system. He released it under the GNU General Public License.
3. The penguin logo of Linux was selected after Linus encountered a penguin that bit his hand during a vacation in the southern hemisphere.
This document provides an overview of Linux shell scripting (Bash) basics. It discusses writing scripts using editors like vi or vim, setting permissions using chmod, executing scripts, variables, arithmetic operations, file manipulation commands, pipes, reading from files, command substitution, background processes, arrays, output redirection, and input redirection. Examples are provided for many common scripting tasks and commands.
NetApp Cluster-Failover Giveback allows a failed NetApp filer head to recover by having the operational head give back its resources. When a head fails, the other head takes over its disks and network connections in a takeover state. To recover the failed head, the operational head must be instructed to perform a giveback command, which will sync up the peers and allow the failed head to resume normal operations. An HA pair consists of two matching storage controllers connected to each other's disk shelves to provide fault tolerance for nondisruptive maintenance.
Linux is an open-source operating system that runs on various hardware platforms. It was created in 1991 by Linus Torvalds and is developed collaboratively by its community of users and developers. Linux exists in many different distributions, or "distros", that package the Linux kernel along with other software. Popular distros include Ubuntu, Fedora, openSUSE, Debian, and Arch Linux. Linux is widely used for servers, mainframes, embedded systems, and as an alternative to Windows on desktop computers and laptops. It offers advantages like open source access, customizability, security, and reliability.
Here are some key things to practice with regular expressions using grep, sed and awk:
- Use grep to search files for patterns using basic regex metacharacters like ^, $, ., *, [, ], etc.
- Use sed for search and replace operations on files using regex to match patterns
- Use awk to parse files into fields based on delimiters like space, comma etc and perform operations on the fields stored in variables $1, $2 etc.
- Write simple awk scripts to print, filter and manipulate data from files. For example print certain fields, filter rows, perform calculations etc.
- Learn about more advanced regex features supported by tools like extended regex in grep, backreferences in sed etc
The document discusses the history and evolution of open source software. It began in the 1970s-1980s as the free software movement. Over time it evolved into both the free and open source software movements. Open source refers to software with source code that is openly available and can be modified. It offers benefits like lower costs, availability of source code, and vendor independence. Examples of widely used open source software include Linux, Apache, MySQL, PHP, and Mozilla. The document also discusses open source languages, databases, and operating systems. It provides case studies on Sahana and an IT project in Kerala, India. Challenges of open source include steep learning curves and lack of standardization. However, it provides flexibility and custom

Managing Ceph operational complexity with JujuShapeBlue
James Page presented on using Juju and charms to manage the operational complexity of Ceph deployments. Juju provides an auto-magic deployment tool and model-driven operations that can be used to deploy Ceph along with related applications like rbd-mirror across multiple data centers. The Ceph charms encapsulate operational knowledge to handle tasks like installation, configuration, upgrades, scaling, and health monitoring. Juju allows defining the application model and relating applications across models, and includes features like MAAS for server provisioning and LXD for containers. Demostrations showed using Juju actions to manage Ceph operations like creating pools, refreshing mirrors, and upgrading versions across availability zones.
This document summarizes the history and key aspects of Linux. It describes how Linux originated from earlier operating systems like MULTICS and UNIX. It provides an overview of Linux components like the kernel, GNU tools, and popular desktop interfaces. It also summarizes common Linux commands for file navigation, editing, and process management. Finally, it gives a brief introduction to the GNOME desktop environment.
The document describes hypervisors and their role in virtualization. It discusses how a hypervisor sits between virtual machines and hardware to provide an isolated environment for each VM. It also compares different types of hypervisors, including describing how early hypervisors used full virtualization through trap-and-emulate to virtualize privileged instructions. The document then discusses the design conditions for a hypervisor based on Popek and Goldberg's virtualization theorem, including how the hypervisor must provide equivalence, performance, and resource control for virtual machines.
Linux was created in 1991 by Linus Torvalds as a free and open-source kernel. It has since grown significantly and is now widely used both for personal computers and in other devices like servers, embedded systems, and smartphones through Android. Some key points in Linux's history include the first Linux distribution Red Hat in 1994, the creation of desktop environments like KDE in 1996, and Android's adoption of the Linux kernel which has given it the largest installed base of any OS. There are now over 600 Linux distributions available for different use cases like Ubuntu, Debian, and Fedora for personal computers and embedded distributions for devices.
