Disk failures in the real world

October 26th, 2009 · 3 Comments

One thing that the sheer scale of the computing landscape has contributed to the field of Computer Science is the opportunity to study these systems statistically – and in particular to prove or disprove various aspects of hardware and software reliability. With respect to disk drives, several large studies of disk drive reliability [2,3,4,7] have [...]

CPU performance and database architectures

December 22nd, 2008 · Comments Off

This month’s edition of Communications of the ACM (December 2008) contains a number of articles related to data management. One that I’ll point out is an interview with relational database pioneer and IBM Fellow Patricia Selinger (nee Griffiths) with James Hamilton (now a VP with Amazon Data Services, having recently left Microsoft). The second is [...]

Trends in hardware: two recent articles

December 10th, 2008 · Comments Off

On 1 December Adam Leventhal of Sun Microsystems posted an article entitled “Casting the shadow of the hybrid storage pool”, where Adam explores the performance and cost-effectiveness of using flash-memory (SSD) devices as cache for primarily disk-based storage architectures: It’s easy to see why using flash as primary storage is attractive. Flash is faster than [...]
