Storage projects

A talk on HEPiX 2009 about iSCSI at CERN
iSCSI technology evaluation and service at CERN and a paper that is still work-in-progress
Tape server architecture research, including testing of high-performance tape drives (see the mini-paper for the calculations)
Fibre Channel service (see its Wiki page)
Co-authored paper (2010) on Lustre evaluation with focus on manageability and lifecycle management

Poster and follow-up paper on Remote Power And Console Management in Large Datacenters at CHEP2010
Console service's website and WIKI page.
A talk about Large-Scale Remote Management via IPMI for HEPiX Fall 2007

Hardware-burn-in tests, and a talk about Increasing Reliability by Testing (on HEPiX 2007 Spring)
...which goes hand in hand with u-boot: a minimal (maintenance) ramdisk environment
hwraidtools, a toolkit to simplify and automatize hardware RAID management on various platforms. I've also contributed to einarc, a similar but more sophisticated project.
Automated pairing of machines for network testing
A small patch to memtest86+ that makes it stop after a configurable number of passes, useful for mass "memtesting"

An unobtrusive Google Calendar alerter called gcalert
Using an old, small laptop/desktop efficiently
Autorip, a command-line no-questions-asked do-the-right-thing DVD-to-highquality-H.264 conversion tool
(source: git clone git://github.com/raas/autorip.sh.git)
Adjust screen brightness on some laptops with Intel VGA chips, like the Toshiba Portege T130 and some Dell models
For lack of anything better including STREAM2, a naive memory bandwidth benchmark
Another Python script to copy JPEG comments into albumshaper Album.xml
A static xHTML photo album generator, now abandoned
Some of the above stuff on freshmeat.net
My attempts at photography

Rxlogd, a syslog collector server that can coexist with the RedHat 3/4 default sysklogd
Traffic shaping on Gigabit Ethernet
Infiniband network interconnect (featuring RFIO over Infiniband)
Traffic Flow Visualisation system: A bandwidth monitor to show traffic trends for high-speed networks (eg. gigabit and above)
Data, links and info on power consumption measurements
UTF-8 on Debian systems -- mostly obsolete by now, some hints remain valid
Talk to a CMS/Hungary group about Make and RPM
Talk to summer students @ 2005 about storage (slideshow) and about Infiniband (slideshow), organized by CERN Openlab
Alternative hardware solutions research (meaning: computing on NVIDIA videocards, Sony PS/2s etc)
Various bits, pieces, Quattor NCM components and suchlike for, among other things, the aforementioned serial console system
On filesystems and clustering: https://twiki.cern.ch/twiki/bin/view/LinuxSupport/DistFsEval
KProbes-based SCSI statistics, mostly useful for tape drives, now superseded by a systemtap-based solution
Evaluation report on the Sun Fire X4500 Server as possible "next-generation" Castor disk server
Testing Fibre Channel disk arrays
Various storage tests at CASPUR, followed by a report by Andrei Maslennikov
The (black) magical world of SUE and CERN Linux 7.3: https://twiki.cern.ch/twiki/bin/view/LinuxSupport/SoftwareUpdatesOn7. Both are retired now (as of 2006).
