Researchers Create Cheap, Flexible, Plastic Flash Memory
Friday, December 11th, 2009
An anonymous reader writes "Researchers at the University of Tokyo, led by electrical engineering professor Takao Someya, have created a new kind of low-cost, plastic, flash memory storage device. Although not as dense or stable as its silicon cousin, the plastic flash memory is useful because of its low cost, simple manufacturing process, and potential use in e-paper or other flexible devices. To demonstrate the memory, Someya's group integrated a 676-memory-cell device with a rubber pressure sensor. The flexible sensor-memory device, which is less than 700 micrometers thick, can record pressure patterns and retain them for up to a day."
DRBD To Be Included In Linux Kernel 2.6.33
Thursday, December 10th, 2009
An anonymous reader writes "The long-time Linux kernel module for block replication over TCP, DRBD, has been accepted as part of the main Linux kernel. Amid much fanfare and some slight controversy, Linus has pulled the DRBD source into the 2.6.33 tree, expected to release February, 2010. DRBD has existed as open source and been available in major distros for 10 years, but lived outside the main kernel tree in the hands of LINBIT, based in Vienna. Being accepted into the main kernel tree means better cooperation and wider user accessibility to HA data replication."

Quebec Data Center Built In a Silo
Thursday, December 10th, 2009
1sockchuck writes "A supercomputing center in Quebec has transformed a huge concrete silo into the CLUMEQ Colossus, a data center filled with HPC clusters. The silo, which is 65 feet high with two-foot thick concrete walls, previously housed a Van de Graaf accelerator dating to the 1960s. It was redesigned to house three floors of server cabinets, arranged so cold air can flow from the outside of the facility through the racks and return via an interior 'hot core.' The construction and operation of the unique facility (PDF) are detailed in a presentation from CLUMEQ."

One Way To Save Digital Archives From File Corruption
Friday, December 4th, 2009
storagedude points out this article about one of the perils of digital storage, the author of which "says massive digital archives are threatened by simple bit errors that can render whole files useless. The article notes that analog pictures and film can degrade and still be usable; why can't the same be true of digital files? The solution proposed by the author: two headers and error correction code (ECC) in every file."
