There are three generalised approaches to using flash memory in storage architectures, categorised in the diagram below: Three Categories of Solution Design The Performance Optimised category takes a no-compromise-on-cost approach to designing for performance. A centralised storage controller that leverages flash memory characteristics to dramatically reduce IO latency and improve IOPS. Significant new engineering work [...]Continue Reading
I just finished reading EMC company blogger, Chuck Hollis article about EMC VFCache, a server side flash storage technology that competes with the Fusion-io, ioDrive head on. Most interestingly, the product name is chosen carefully to ensure customers don’t get confused that VFCache might be designed to replace the normal disk based EMC storage array controller products. [...]Continue Reading
I published a brief article last month about a set of test we were doing on a production data warehouse that was performing very poorly. Running the database on a Dell Server with 4 x 73GB SAS drives configured in RAID0 we got a respectable 575 IOs per second (IOPS) on a random write test. [...]Continue Reading
I have been looking a solving some database performance issue recently particularly around a large SQL Server database that looked like it was going to need to move to a dedicated (and expensive) data warehouse platform to hit our challenging performance targets. I am just about to try an alternative hardware solution that has great [...]Continue Reading
