Well actually I meant mobs of flash, but I couldn’t resist the word play. Although, come to think of it, flash mobs might be the right way to describe the density of flash memory system vendors here at Oracle Open World. Walking around the exhibits it seems as if every other booth is occupied by someone selling flash memory systems to accelerate Oracle’s database, and all of them claiming to be: 1) faster than anything that Oracle, who already integrates flash into its systems, offers, and 2) faster and/or cheaper than the other flash vendor two booths down the aisle.
All joking aside, the proliferation of flash memory suppliers is pretty amazing, although a venue devoted to the world’s most popular database would be exactly where you might expect to find them. In one sense flash is nothing new – RAM disks, arrays of RAM configured to mimic a disk, have been around since the 1970s but were small and really expensive, and never got on a cost and volume curve to drive them into a mass-market product. Flash, benefitting not only from the inherent economies of semiconductor technology but also from the drivers of consumer volumes, has the transition to a cost that makes it a reasonable alternative for some use case, with database acceleration being probably the most compelling. This explains why the flash vendors are gathered here in San Francisco this week to tout their wares – this is the richest collection of potential customers they will ever see in one place.
