Exploring High Bandwidth Filesystems on Large Systems
White Paper This paper presents the results of an investigation conducted by SGI into streaming filesystem throughput on the Altix platform with a high bandwidth disk subsystem. This is followed up with a set of baseline results and observations using XFS on a... [08 Jul 2008]
White Paper: Indestructible Firewall in a Box V1.0
White Paper In this paper, the procedure for creating an embedded firewall whose root filesystem is loaded from a flash disk and then executed from a RAMdisk will be illustrated. It has the advantages of being very light and fast, being impervious to... [30 Jun 2008]
Host-Based Intrusion Detection Systems
This paper recognizes four different methods of host-based intrusion detection: filesystem monitoring, logfile analysis, connection analysis and kernel-based intrusion detection. Host-based Intrusion Detection Systems can be used to determine if a... [03 Jun 2008]
Linux Server Hacks: Profile Your Systems Using /proc
White Paper This filesystem is a portal into the depths of what the running kernel and the system load look like, and it provides a full profile of the hardware in use on the local system. A great place to start hunting for information is the /proc filesystem. [24 Oct 2007]
System Performance Tuning: Memory
Virtual memory is consumed by the system kernel, filesystem caches, intimately shared memory, and processes. Physical memory is a set of integrated circuits designed to store binary data. This storage has two characteristic properties: it is... [17 Oct 2007]

A Brief UNIX Filesystem Review
White Paper The UNIX operating system is built around the concept of a filesystem which is used to store all of the information that constitutes the long-term state of the system. This state includes the operating system kernel itself, the executable files for... [22 Jun 2007]
Demands, Solutions, and Improvements for Linux Filesystem Security
White Paper Once the data leaves that machine, or if the machine itself is physically compromised, those access control mechanisms can no longer protect the data in the filesystem. No one library, application, or kernel feature can stand alone in providing... [18 May 2007]
Filesystem Performance and Scalability in Linux 2.4.17
White Paper Although the best-performing filesystem varies depending on the benchmark and system used, some larger trends are evident in the data. The Linux kernel is unique in that it supports a wide variety of high-quality filesystems. [03 Apr 2007]
Union Mounts for Linux
White Paper In combination with an execute-in-place filesystem, union mounts can be used for efficient software management on read-only filesystems shared between Linux z/VM guests. After giving an overview about union mounts and some demonstrations, this... [03 Apr 2007]
Shared Parallel Filesystems in Heterogeneous Linux Multi-Cluster Environments
White Paper The authors comment on the feature sets of each filesystem, describe the implementation and configuration experiences, and present initial performance benchmark results. Three of the systems - GPFS, Lustre and TerraFS - depend on specific kernel... [01 Apr 2007]
Migrating to Oracle ASM Using Oracle Enterprise Manager 10g Database Control
White Paper Oracle Automatic Storage Management (ASM), introduced in Oracle Database 10g Release 1, is a special-purpose cluster filesystem embedded into the Oracle kernel; it removes the need for a third-party volume manager and filesystem. [11 Oct 2006]
Guide to Linux Filesystem Mastery
White Paper The terminology used to discuss Linux filesystem concepts is a bit confusing for newcomers. The terms filesystem and file system are used interchangeably in the Linux documentation to refer to several different but related concepts. [11 Oct 2006]
Filesystem Labeling in SELinux
White Paper Given this increasing user base, this paper takes a closer look at filesystem labeling under SELinux. With NSA Security-Enhanced Linux now integrated into the 2.6 kernel and making its way into distributions, an increasing number of people likely... [08 Dec 2004]
Oracle Database 10g Migration to Automatic Storage Management
White Paper ASM provides filesystem and volume manager capabilities built into the Oracle database kernel. In Oracle Database 10g, storage management and provisioning for the database has becomes much more simplified with a new feature called Automatic Storage... [13 Oct 2004]
