Tintri gets $25M to tune flash storage for VMs

A Mountain View, Calif., storage startup called Tintri has raised $25 million for its virtualization-focused flash storage appliances. The appliances, called VMstore, mix hard-disk and solid-state drives and promise better storage performance than traditional systems for virtualized applications.

We wrote about Tintri last summer as the storage system behind gaming startup Digital Chocolate. Essentially, each appliance contains up to 13.5TB of usable capacity and boosts performance of virtualized environments because the storage software is designed from the ground up for virtualization. The idea is that it’s easier for storage administrators because they can track performance at the virtual-machine level — just like with their virtualization-management software — rather than by trying to negotiate the traverse between VMs on one side and LUNs, files and other traditional storage-system divisions on the other side.

Flash storage is becoming increasingly appealing appealing for virtualized applications such as databases that need higher throughput than hard disks can comfortably handle. Rather than providing brute performance with an all-flash array, though, Tintri claims its specialized software lets it make maximum use of a relatively small flash tier (only 2.4TB of raw capacity on its high-end appliance compared with 24TB of hard disk capacity) while still keeping prices low.

Tintri has raised $60 million thus far. Menlo Ventures led this round and was joined by existing investors NEA and Lightspeed Venture Partners.
