NetCache is a former web cache software product which was owned and developed by NetApp between 1997 and 2006, and a hardware product family incorporating the NetCache software.
The NetCache software started as a commercial fork of the Harvest Object Cache[1][2] developed by Internet Middleware Corporation (IMC), which consisted of former Harvest project developers including Peter B. Danzig, a professor at University of Southern California.
[3] In 2006 NetApp sold the NetCache business (but not technology) to Blue Coat Systems,[7][8] who had a similar line of ProxySG appliances which became the more expensive product for existing NetApp customers.
[9] The hardware NetCache appliance included the NetApp Data ONTAP microkernel, with its Write Anywhere File Layout file system, achieving four times the throughput as software equivalents available at time, according to NetApp comparisons.
[10] Starting with ONTAP version 9.5 similar functionality was introduced under FlexCache name.
