Software-defined storage is different from storage virtualization, which pools the capacity of multiple storage devices or arrays into a single pool that appears as if it were sitting on a single device. Software-defined storage is not about separating capacity from a storage device, but instead is about separating the storage features, or services, from the storage device.
Farronato said VMware explored a number of pricing options for VSAN with its customers, technology partners and channel partners, and settled on per-processor pricing because of its simplicity.
"We want to make it very simple for customers and vSphere administrators," he said. "These people are used to buying on a per-processor basis. It's simpler than on a per-VM [virtual machine] or by capacity."
The per-processor pricing also aligns with the idea of building scale-out environments, which is when the addition of processor nodes increases the performance of an entire system. "As you grow nodes, you know how many licenses you will need," Farronato said. "There's no capacity restriction, no performance restriction."
At the price charged by VMware, customers will be paying as low as 25 cents per I/O per second and/or as low as 50 cents per usable GB of data in a RAID N+1 configuration, he said .
VMware's solution providers will benefit from VSAN in a couple of ways, Farronato said.
Partners who register a deal for VSAN get an incremental 10 points of margin above the normal margin for the software, he said.
Partners can use VSAN to extend their services offerings around other offerings, including virtual desktop infrastructure, disaster recovery and business continuity, he said. "VMware also plans to create new services that can be leveraged by partners around Virtual SAN," he said.
