Chuck, as from the first time i met you when you convinced 100's at EMC that selling Enterprise Storage made sense for customers, you have always been ahead of your time every since.

Server Flash from Virident used by VMW and EMC helps apps sing.

I'm in the camp of agreement. At the VMUG in Houston yesterday was my first exposure to SimpliVity, which has fully adopted this as the path forward (though I didn't get details on scale limitations). EMC's own Isilon has pushed this case with being able to run HDFS directly on the what was historically just a storage platform. And Avamar takes the same approach for a purpose-built-backup-appliance that also runs all the software of the backup application.

These architectures seem to provide a simpler management model, but also more redundancy in being able to say N+1, N+2, N+3... etc, "how many failures do you want to protect against?" type of options that a dual-controller array just can't offer.


I seem to have missed something - the point of external storage has always been the need for high availability which was typically enacted through the clustering of compute nodes and these have always required external storage for this to happen. Storage arrays took over from DAS (in the mainstream) when cost-effective arrays became a viable option to buying/supporting/hosting the 10s or even 100s of DAS JBODs that a single array could replace.
Admittedly, VMware VSAN appears to address this, however it will need to demonstrate its robustness and performance before the market moves from external storage; and judging by the problems I have seen with the lower-tier offerings such as VSA, that might still be in the distance.
