==History==
Tintri was founded in 2007 by Kieran Harty, who had led development at [[VMware]] as their executive vice president of engineering from 1999 to 2006.
A native of [[Ireland]], Harty had graduate degrees from [[Trinity College, Dublin]] and [[Stanford University]].<ref>{{Cite news |title= J-1 visa leads Trinity graduate to Silicon Valley success |newspaper= The Irish Times |date= August 12, 2016 |url= http://www.irishtimes.com/business/technology/j-1-visa-leads-trinity-graduate-to-silicon-valley-success-1.2750587 |access-date= October 17, 2016 }}</ref>
Its initial objective was solving the mismatch between conventional storage and the demands of applications in [[virtual machine]] (VM) environments, which causes complex configuration and management as well as over-provisioning.<ref>{{cite web |author= Lee Pender |title= Storage for the modern data center |date= July 1, 2013 |url= http://virtualizationreview.com/articles/2013/08/09/road-to-vmworld-2013-storage-for-the-modern-data-center.aspx |work= Virtualization Review |access-date= January 29, 2017 }}</ref>

==Technology==
The Tintri VMstore uses VMs and [[virtual disk]]s — in place of conventional storage abstractions — as core system management constructs. The VMstore offers a set of open interfaces for automation and orchestration in cloud environments. 
Tintri's architecture allows a user to set quality of service (QoS) for individual VMs, vDisks and containers, which allocates minimum or maximum performance resources according to need. The file system automatically monitors and controls IO to those VMs, vDisks and containers to eliminate conflict, often referred to as 'noisy neighbor syndrome'. And Tintri provides a global view of all the VMs stored on the VMstore, including real-time view of latency from guest VMs, vSphere hosts, the network and storage.

Tintri VMstores are accessed by clients over standard file service protocols such as the [[Network File System]] (NFS) and [[Server Message Block]] (SMB).<ref name="yellow2015" /> The software runs on a customized [[Linux]] operating system.  <!-- The majority of the company's intellectual property is implemented in a custom user-level filesystem process, ironically named realstore. needs source, seems opinion? -->
