If you run into any dependency issues, run apt-get f install to resolve them. Install the FUSE and the Opendedup packages: cd opendedup-fuse-2.9 sudo dpkg -i fuse_2.9.0-opendedup_b sudo dpkg -i fuse-utils_2.9.0-opendedup_all.deb sudo dpkg -i libfuse2_2.9.0-opendedup_b sudo dpkg -i libfuse-dev_2.9.0-opendedup_b cd. wget wget tar -xzf opendedup-fuse-2.9.tar.gz

Next download and extract SDFS and FUSE: Garrick, shrink below. Then edit the /etc/security/nf file to include the following lines at the bottom of the file: soft nofile 65535 hard nofile 65535 Set Java to the correct version using the update-alternatives -config java command and select version 1.7. SDFS runs as a module under FUSE (File System in User Space) in a separate space from the kernel, so the underlying filesystem is almost irrelevant.Īfter the base install is complete, run the following command to install the necessary packages using apt-get (make sure use to use sudo to run all of the following commands): apt-get install openjdk-7-jre attr nfs-kernel-server ↪samba libselinux-dev libsepol1 Let the setup program auto-format your partitions (ext4), as this has no bearing on SDFS. Once your hardware is ready, install Ubuntu server 12.04圆4 from CD, accepting all the defaults and making any regional changes necessary. If you want to run live VMs off your deduped volumes, SAS will give you the performance you'll need. If you are looking for low-cost backups, SATA is the way to go. In the end, it will come down to your intended use of dedup. I don't believe there is any improved deduplication in using SAS over SATA. As expected, SAS was snappier in response time, but deduplication rates were nearly identical on both. I also mixed SATA and SAS drive types in my builds. AMD and Intel multicore platforms were used in the process, and SDFS ran flawlessly on both. This is the minimum amount required, but to get the best performance out of your server, you should have an ample supply of memory as the dedup process is memory-intensive. At least 2GB of memory was used on each build. If you are considering piloting, or already have decided on implementing Opendedup, you may have different successes or failures.Īll of the server builds for this article were built using Ubuntu 12.04圆4. Bear in mind when reading this article that “your mileage may vary”. Instead, these tests were aimed at achieving the highest rate of deduplication with the sample data. Plenty of performance statistics are hosted at the project's site. These scenarios were not intended as performance tests (speed, reads, writes and so forth).

In this article, I walk through how to build a server with a deduped SDFS volume and then review the results of several real-world test scenarios designed to gauge how well Opendedup actually dedupes.

SDFS provides many of the features of commercial dedup products at none of the cost.

Now there is an open-source challenger in Opendedup-a project that develops the (user) Space Deduplication File System (SDFS). It was cost-prohibitive for most of the SMB market. Entry dedup systems start at five figures and quickly climb from there. Until recently, the dedup field was tightly guarded by a few big-name vendors. Then, if identical data needs to be written to the disk in the future, instead of writing it twice, it will use a pointer to the data already on the disk.

It entails identifying common data and writing it only once to disk. It can be hardware- or software-based and performed at either the file or block levels of a storage system. The culmination of this research is deduplication or dedup.ĭeduplication is simply the process of eliminating redundant data on disk. At the same time, there has been research to develop more efficient ways to store data on disk. During the last two decades, great strides have been made to increase disk capacity and performance. From business data to consumer content, the demand for storage has never been higher. In the digital age, we consume storage space at an exponential rate.
