Using Advanced xBSD Based Servers for High School
Zadina, Martin ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
This work is about setting up Samba software on server with operating system from BSD family to primary domain controller rule in the high school computer network environment with Microsoft Windows stations. After introduction to Samba software there is examined problem of Windows network based on SMB protocol. There are described steps that are necessary to setup Samba software, disk sharing services, creation of user accounts and adding client stations to domain trust. At the next there is described problematic of network printing in the Windows environment, print servers and the solution with classical printing support in FreeBSD and CUPS printing support. In the next part there is described mass installation procedure of Windows stations with same hardware configuration. At the finish, there are noticed some tasks that are necessary for next operation of installed system.

Tax Documentation System for Linux
Prouza, Jakub ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
This thesis is about concept and implementation of a system uses for simple tax account management in GNU/Linux operating systems. The application has been created by wxWidgets tools library and user's data are saved and encrypted into a SQLite database. Present situation of programs for tax account management under GNU/Linux systems and the goals of this concept are described in the first chapter. The next chapter is describing terms and procedures which are necessary for understanding of tax account management according law. Other chapters deal with the concept itself and the implementation. Conclusion of the thesis is devoted to a review of benefits and further development of the concept.

Online Deduplication for Btrfs
Křížek, Martin ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
Btrfs je copy-on-write linuxový souborový systém, který obsahuje vlastního správce oddílů a podporuje efektivní operace se snapshoty. Online deduplikace dat je metoda odstranění duplicitních bloků dat ještě předtím než jsou zapsány na disk. Tato funkcionalita šetří místo na uložišti avšak může v jistých případech znamenat pokles výkonu při zápisu. Hlavním využitím jsou soubory obrazů disků virtuálních strojů. Takové soubory obsahují z velké části stejná data (stejný operační systém) a tedy tyto části lze zapsat na disk pouze jednou. Tato diplomová práce se zabývá návrhem a implementací online deduplikace pro souborový systém Btrfs.

Comparison of Parallel File Systems
Pazdera, Michal ; Michal, Bohumil (referee) ; Kašpárek, Tomáš (advisor)
The goal of this thesis was to explore several parallel file systems, and to evaluate their performance under various conditions. The main focus of this assessment were read and write speeds in different workloads, the reliability of each system, and also their ability to protect from data loss. Initially, this thesis introduces eight of the most commonly used parallel file systems. From these, three were selected for further testing: Lustre, GlusterFS, and CephFS. To be able to evaluate their performance accurately, a suite of automated tests was developed. These benchmarks were run for each individual file system in our testing lab. The final part of this work evaluates the results and discusses the features of each of the file systems and their suitability for particular workloads.
