Open Source Solutions for Building Your Own Storage Area Network and Network Attached Storage
Open Source Solutions for Building Your Own Storage Area Network and Network Attached Storage Author, Balakrishnan Subramanian A Data Science Foundation White Paper May 2020 --------------------------------------------------- Data Science Foundation Data Science Foundation, Atlantic Business Centre, Atlantic Street, Altrincham, WA14 5NQ Tel: 0161 926 3641 Email: [email protected] Web: www.datascience.foundation Registered in England and Wales 4th June 2015, Registered Number 9624670 www.datascience.foundation Copyright 2016 - 2017 Data Science Foundation 1. INTRODUCTION Generally, Storage solutions can be grouped into following four categories: SoHo NAS systems, Cloud-based/object solutions, Microsoft Storage Server solutions, Enterprise NAS (Networked Attached Storage) and Storage Area Network (SAN) solutions. Enterprise NAS and SAN solutions are generally closed systems offered by traditional vendors like EMC and NetApp with a very large price tag, so many businesses are looking at Open Source solutions to meet their needs. This is a collection of links and brief descriptions of Open Source storage solutions currently available. Open Source of course means it’s free to use and modify, however some projects have do commercially supported versions as well for enterprise customers who require it. 1. Factors for choosing Storage Solutions When you are in the need of Storage solutions for managing your own infrastructure in your private Data Center, there are many offerings but selecting the right one depends upon your requirement. Factors involved in selecting a Storage type Budget Type of Data that you want to store Scaling concerns and Usage pattern In this article, we will be discussing two different methods (i.e. NAS and SAN), these two methods define the Structure of the storage, it is important to choose the right one based upon your use case and type of data. -
Github: a Case Study of Linux/BSD Perceptions from Microsoft's
1 FLOSS != GitHub: A Case Study of Linux/BSD Perceptions from Microsoft’s Acquisition of GitHub Raula Gaikovina Kula∗, Hideki Hata∗, Kenichi Matsumoto∗ ∗Nara Institute of Science and Technology, Japan {raula-k, hata, matumoto}@is.naist.jp Abstract—In 2018, the software industry giants Microsoft made has had its share of disagreements with Microsoft [6], [7], a move into the Open Source world by completing the acquisition [8], [9], the only reported negative opinion of free software of mega Open Source platform, GitHub. This acquisition was not community has different attitudes towards GitHub is the idea without controversy, as it is well-known that the free software communities includes not only the ability to use software freely, of ‘forking’ so far, as it it is considered as a danger to FLOSS but also the libre nature in Open Source Software. In this study, development [10]. our aim is to explore these perceptions in FLOSS developers. We In this paper, we report on how external events such as conducted a survey that covered traditional FLOSS source Linux, acquisition of the open source platform by a closed source and BSD communities and received 246 developer responses. organization triggers a FLOSS developers such the Linux/ The results of the survey confirm that the free community did trigger some communities to move away from GitHub and raised BSD Free Software communities. discussions into free and open software on the GitHub platform. The study reminds us that although GitHub is influential and II. TARGET SUBJECTS AND SURVEY DESIGN trendy, it does not representative all FLOSS communities. -

Three Open Source Network Storage Software
Three Open Source Network Storage Software Whether you’re looking to create a scalable storage solution for your organization or a simple and easy to setup storage box for your home or small office, here are three packages that will meet all your network storage requirements. You can either download their latest editions or take them from this month’s PCQ DVD. - Sandeep Koul NAS4Free This software is actually related to FreeNAS (the one we’ve done a detailed implementation guide on in this issue), which is probably why it has a similar sounding name. In fact, NAS4Free is a direct continuation of efforts that went into developing the original FreeNAS code, which started in 2005 and continued till 2011 by the name FreeNAS. Post 2011, these two packages were developed separately by two different communities. Like FreeNAS, NAS4Free also comes loaded with features like sharing across Windows, Apple, and UNIX-like systems, includes ZFS, software RAID (0,1,5), disk encryption, S.M.A.R.T / email reports etc. It supports all common network storage protocols including CIFS (samba), FTP, NFS, TFTP, AFP, RSYNC, Unison, iSCSI, UPnP, Bittorent (initiator and target). All these features can be configured through the software’s Web interface. The package is an embedded Open Source Network-Attached Storage distribution and is based on FreeBSD. Download from: www.nas4free.org/ OpenMediaVault The great feature about this storage package is the modular design of its framework, due to which its functionality can be enhanced via plug-ins. OpenMediaVault is based pcquest.com twitter.com/pcquest facebook.com/pcquest linkd.in/pcquest [email protected] DECEMBER 2012 PCQUEST 51 COVER STORY on Debian Linux and contains services like SSH, (S)FTP, with the pricing determined on a per-terabyte and per- SMB/CIFS, DAAP media server, RSync, BitTorrent client server licensing basis. -
