The benchmark is the SPECsfs2008 CIFS file access benchmark. There is a similar benchmark for NFS which is much more popular in terms of supplier submissions, with BlueArc, HP, Isilon, NetApp and others reporting results.

Given a directory on a drive, and a minimum and maximum file size, this program will graph the frequency with which files within that size range appear in that directory (and all subdirectories). See screenshot.
One task that every one should do it is deleting useless files. If you do not, you will run out of disk space inevitably. Then, you will wonder where my disk space has gone? Filelight is the answer to you. Filelight creates an interactive map of concentric, segmented rings that help visualize disk usage on your computer. Like a pie-chart, but the segments nest, allowing you to easily see which files are taking up all your space.
Has anyone had any success with using the iSCSI target of OpenFiler to provide storage to a Cirtix XEN Server (formerely XenSource) as a storage repository. Here is the scenario that will reproduce a failure every time on the OpenFiler server.
Thankfully, Rocks v4.3 kernel roll and Lustre v1.6.1 appear to be based on the same kernel version. This saved me from having to get the kernel source, and patch it for Lustre. I've done that before with some success, but I'm happy to be able to avoid doing it again. The following applies to setting up Rocks so that Lustre is installed and ready on compute nodes. I also put Lustre on the frontend node, but that was done manually, simply by installing the rpms, and configuring grub.
The developers have released version 1.0 of the XtreemFS distributed file system. The result of a research project funded by the EU, XtreemFS is designed for distributed data management in grids, but is also meant to simplify accessing local files over the internet. It's easy to set up, supports RAID-0 (striping) over different machines and file replication over the network, encrypts data, and provides security mechanisms to ensure only authorised users can access shared files. Unlike sharing via NFS or SMB/CIFS, the file system can extend over several servers, provides security mechanisms, and is optimised for use over slow and not totally reliable internet connections. The file system runs in user space (via FUSE under Linux, via Dokan under Windows), so it can do without drivers or a kernel module. Linux and Windows are supported on the client side, and a Mac OS X client is under construction. The server runs under Linux and Solaris, and the software is licensed under the GPLv2.
Score one for Linux developers. Andrew Tridgell, one of the lead developers on the Samba project, may have developed a workaround which will bypass a Microsoft patent on the ubiquitous FAT, VFAT and FAT32 file systems
There are many people who are influential in Linux. Many of them you are already aware of, but there are some, who are very influential, that you might not be aware. Valerie Aurora is a very influential thought leader in the Linux and FOSS community. She is responsible for the ChunkFS concepts and for much of the current work in Union file system work within Linux.
High Performance and Scalability\n\nFor the world's largest and most complex computing environments, the Lustre™ file system redefines high performance, scaling to tens of thousands of nodes and petabytes of storage with groundbreaking I/O and metadata throughput.

University Information Technology Services (UITS) at Indiana University announced today that it has dedicated over 350 terabytes (TB) of new storage platforms to support collaborative research projects mounting the Lustre file system across the TeraGrid n
How do I restart NFS server when network link goes down between two servers or NFS client / server under CentOS 4.x / RHEL / CentOS Linux 5.x? Forceful umount command result into more problems such as unresponsive NFS server and cold reboot only solves my
