Volume 4A of Knuth's TAOCP Finally In Print 173

jantangring writes "It's been 28 years since Volume 3 of Donald Knuth's The Art of Computer Programming was published. The book series is a classic work of computer science in spite of the fact that still more than half of the seven volume series is still to be finalized. In 1992 Donald Knuth retired to medieval monkness in order to finish his work. After many long years in draft, volume 4A now in print and you can get it in a boxed set if you don't mind admitting that you don't already own the first three volumes. They won't be checking if you read it."

Are RAID Controllers the Next Data Center Bottleneck? 171

storagedude writes "This article suggests that most RAID controllers are completely unprepared for solid state drives and parallel file systems, all but guaranteeing another I/O bottleneck in data centers and another round of fixes and upgrades. What's more, some unnamed RAID vendors don't seem to even want to hear about the problem. Quoting: 'Common wisdom has held until now that I/O is random. This may have been true for many applications and file system allocation methodologies in the recent past, but with new file system allocation methods, pNFS and most importantly SSDs, the world as we know it is changing fast. RAID storage vendors who say that IOPS are all that matters for their controllers will be wrong within the next 18 months, if they aren't already.'"
