Linux based SMB NAS System Performance Optimization - By Sagar Borikar and Rajesh Palani

SMB NAS systems range from the low end, targeting small offices (SOHO) that might have 2 to 10 servers, requiring 1 TB to 10 TB of storage, to the high end, targeting the commercial SMB (Small to Medium Business) market. Customers are demanding a rich feature set at a lesser cost, given the relatively cheap solutions available in the form of disk storage, compared to what was available 5 years ago. One of the key factors in deciding the unique selling proposition of the NAS (Network Attached Storage) in the SOHO market is the network and storage performance. Due to extremely competitive pricing, many NAS vendors are focused on reducing the manufacturing costs, so one of the challenges is dealing with the scarcity of system hardware resources without compromising the performance. This article describes the optimizations (code optimizations, parameter tuning, etc.) required to support the performance requirements in a resource-constrained Linux based SMB NAS system.

Every day, more businesses, organizations, and institutions of all kinds generate media assets that become part of their value chains, their know-how and production processes. We understand a multimedia digital asset not only as a media file (audio, video, or image) but as the combination of the file itself and its associated metadata; this allows, from an organizational perspective, exploiting, analysis, and documentation.

There are quite a few April events of interest to the Linux and Open Source professional. The menu includes hard-core Linux development, Android, MySQL, system and network security, and cloud computing.

I began this series with HAL: Part 1 Preliminaries. I followed this with HAL: Part 2 My Favourite Aliases. This article deals with functions and another will talk about scripts.

My younger son (Rob, 22 soon) wants more Internet. Of course. 20GB a month is not enough for him. While he was away, my wife and I were pushing to use 20% of that.

Administrators of multiple servers know that updating software packages can be a tedious task. It requires a log in, followed by the execution of a "yum update" or something similar for each server. Although several tools exist for enabling administrators to update packages automatically, including yum-updatesd and yum-cron, updating the packages without confirmation possibly leads to further issues.

We made a small flurry of announcements recently, all of which were related to cloud computing. I think it is worthwhile to put some context around Ubuntu and the cloud and explain a little more about where we are with this critical strategic strand for our beloved OS.

December 1996, I had just finished my first semester of college. For Winter break, I decide to go to my uncle’s house in Long Island, NY. My uncle, a PhD student at Stony Brook University, hands me a brick-like book that comes with a free operating system called Red Hat Linux, version 3.0.3.

When dealing with authentication, there are a myriad of systems out there that validate user identity and permissions: shadow passwords, Kerberos, NIS and LDAP, just to name a few.
