pnfs architecture 2

Parallel NFS (pNFS) – Part 1 (Introduction)

Parallel NFS (pNFS) is a part of the NFS v4.1 standard that allows compute clients to access storage devices directly and in parallel. The pNFS architecture eliminates the scalability and performance issues associated with NFS servers deployed today. This is achieved by the separation of data and metadata, and moving the metadata server out of the data path.

Linux Deduplication and Compression: The Ultimate Guide to Saving Space

Cost of storage is the biggest piece of IT budget in any company (Of course not EMC, HPE or other like them 😀 ) and the storage spaces is eating by databases, other data files and backup files as well. Lot of those data file not be used once generated!. I have serious issue with these types of data and especially log files that one of dark data types. I can’t stop generating those data and the related teams are always crying about free space on their servers. They want just Linux servers (Seems, they don’t know Windows has NFS services as well), because they are using shared space on application servers to storing log files and others via NFS. I have offered other solutions such as using Windows as NFS server and use deduplication on Windows Servers, this feature is really good. I have used Windows deduplication on our backup proxy servers and result was incredible. Anyway, they want to Linux server (Not even other Unix-Like!), so I started to googling these: Don’t panic, most Linux’s modern file systems have no native deduplication and transparent compression and must be enabled with third-party software. Let’s see what is deduplication and...

What’s FreeDOS?

FreeDOS is an open source DOS-compatible operating system that you can use to play classic DOS games, run legacy business software, or develop embedded systems. Any program that works on MS-DOS should also run on FreeDOS. It doesn’t cost anything to download and use FreeDOS. You can also share FreeDOS for others to enjoy! And you can view and edit our source code, because all FreeDOS programs are distributed under the GNU General Public License or a similar open source software license. FreeDOS Software Since 1998, each program included in the FreeDOS distribution is made available as a “package.” The distribution divides these FreeDOS software packages into groups, sometimes called “sets.” The BASE package group contains only those programs that reproduce the functionality of classic DOS systems. The other package groups contain software that you may find useful, such as games, editors, and developer tools. BASE Programs that provide the functionality of classic DOS Archivers Tools to compress files and create archives. Boot tools Utilities to help you boot your computer Development Development tools such as compilers and assemblers Editors Editors and simple word processors that let you edit text files Emulators Programs that emulate other systems Games Fun games that you can...
