VMware Virtual SAN Move, Explained

VMware seeks to dominate virtual storage with Virtual SAN as, at the same time, it gains ground in network virtualization.

App question
"With Virtual SAN, server-based storage is near the CPU and has the shortest access route over which to deliver its data, compared to external devices and arrays." This is a nitty-gritty but key fact. What enterprise applications will benefit the most from this arrangement, Charlie?

Is VMware acting like an EMC stepchild, or do I have this wrong?
Good question, Laurie. VMware suggests only certain kinds of applications, such as management of virtual desktops, an area it wants to promote, and test/dev, disaster recovery should be the first implementations. It's emphasizing the cases of rapid set up and  tear down of virtual machines on a large scale. But I'd like to know why an I/O intensive database application wouldn't also benefit? For that matter, a low priority application with infrequent I/O could benefit by being placed on the same set of servers as high priority ones, but with policies that restrict it in times of high traffic. The conclusion I'm tempted to draw is that management of all virtualized applications will benefit. As soon as virtualization managers gain confidence in the process, they'll put it to work beyond the measures VMware suggests. Is VMware under-selling? Acting like an EMC stepchild, perhaps? Or do I have this wrong?

Will Virtual SAN override hardware manufacturers' converged architectures?
And another thing. When I asked whose server hardware supports Virtual SAN, I heard Cisco, IBM, Dell, Fujitsu but did not hear HP mentioned, which made me suspicious, needlessly so. HP is on the list of hardware suppliers providing certified servers here: http://www.vmware.com/resources/compatibility/search.php?deviceCategory=server  But I think Virtual SAN brings VMware a step closer to subsuming the converged architectures offered by HP, Cisco and EMC/VMware/Cisco's joint subsidiary, VCE.

Re: App question
This is interesting. VMware is essentially going otuside of server infrastructure VMs and moving further into more appliance-like hardware. 

It makes sense. But it does make one wonder what other hardware appliances VMware can get its hands on. The SAN market is a huge one. But if they are able to roll this out successfully, traditional SAN providers may have no choice but to partner with VMware.

Given EMC, SAN seems like the least threatening move for VMware to take here. Extended out, though, does this strategy call the whole VCE/Vblock alliance into question?

Fusion IO seems to be taking the ball and running with this.  http://www.fusionio.com/overviews/maximize-vsan-performance-consolidation-and-scalability-with-iomemorys-unrivalled-performance-density

I would have to guess that yes this can be used for performant applicaitons they are just being careful stepping on toes.
