NetCache

The NetCache software started as a commercial fork of the Harvest Object Cache{{cite web|url=http://www.usenix.org/publications/library/proceedings/usenix-nt97/usage_abstracts/Brian_Wink.html |title=Brian Wink |publisher=Usenix.org |date= |accessdate=2012-08-07}}{{cite web | title=NetCache Technical Paper | url=http://www.linofee.org/~jel/da/papers/netcache1.ps.gz | accessdate=2009-05-05}} developed by Internet Middleware Corporation (IMC), which consisted of former Harvest project developers including Peter B. Danzig, a professor at University of Southern California.{{cite journal | journal = Network World | date = 21 July 1997 | author = Chris Nermey | title = New Web Caching boxes promise better bandwidth control }} In late 1996 the software was named Internet Middleware Object Cache,{{cite web|url=http://www.netcache.com/ |accessdate=2012-08-07 |title=Internet Middleware Object Cache: Cached-2. |publisher=Internet Middleware Corporation |date=September 10, 1996 |url-status=dead |archiveurl=https://web.archive.org/web/19961112032719/http://www.netcache.com/ |archivedate=November 12, 1996 }} and it was referred to as Cached 2 and later Cached 3.{{cite web |url=http://excalibur.usc.edu/ |title=The Harvest Cache and Httpd-Accelerator |date=1996-11-22 |accessdate=2012-08-07 |url-status=dead |archiveurl=https://web.archive.org/web/19961122024331/http://excalibur.usc.edu/ |archivedate=November 22, 1996 }}{{Cite web |url=http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.57.1141&rep=rep1&type=ps |title=Building a web cache system - Architectural Considerations |citeseerx=10.1.1.57.1141 |access-date=2010-08-23 |archive-date=2012-10-08 |archive-url=https://web.archive.org/web/20121008132853/http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.57.1141&rep=rep1&type=ps |url-status=dead }}

In 1997 IMC was acquired by NetApp, and the software was renamed NetCache, with Danzig becoming chief architect and CTO of NetCache division.

In 2006 NetApp sold the NetCache business (but not technology) to Blue Coat Systems,{{cite news | url = https://www.theregister.co.uk/2006/06/23/netapp_sells_netcache/ | title = NetApp flogs NetCache to Blue Coat | newspaper = The Register | date = 23 June 2006 | author = Chris Williams }}{{cite news | url = http://www.arnnet.com.au/article/167954/blue_coat_looks_partners_help_netcache_transition/ | title = Blue Coat looks for partners to help NetCache transition | author = Rebecca Munro | publisher = ARNnet | date = 19 October 2006 }} who had a similar line of ProxySG appliances which became the more expensive product for existing NetApp customers.{{cite news | url = http://news.techworld.com/networking/6297/netapp-sells-netcache-to-blue-coat/?siteSection= | title = NetApp sells NetCache to Blue Coat | author = Bryan Betts | publisher = Techworld | date = 26 June 2006 | access-date = 25 August 2010 | archive-date = 10 March 2012 | archive-url = https://web.archive.org/web/20120310063831/http://news.techworld.com/networking/6297/netapp-sells-netcache-to-blue-coat/?siteSection= | url-status = dead }}

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.{{cite web | title = NetCache Architecture and Deployment | citeseerx = 10.1.1.27.8507 | author = Peter Danzig | date = February 1997 }}; also {{cite journal | journal = Computer Networks and ISDN Systems | volume = 30 | issue = 22–23 | date = 25 November 1998 | pages = 2081–2091 | doi = 10.1016/S0169-7552(98)00250-5 | archiveurl = https://web.archive.org/web/19990508132725/http://www01.netapp.com/technology/level3/3029.html | url = http://www01.netapp.com/technology/level3/3029.html | title = NetCache Architecture and Deployment | archivedate = 1999-05-08 | url-status = dead | last1 = Danzig | first1 = Peter | citeseerx = 10.1.1.27.8507 }} Starting with ONTAP version 9.5 similar functionality was introduced under FlexCache name.

As of November 2005, three hardware models were being offered:{{cite web | title = NetCache hardware Product Family | url = http://www.echostor.com/pdfs/netcache_family.pdf | author = NetApp | date = November 2005 }}{{dead link|date=February 2018 |bot=InternetArchiveBot |fix-attempted=yes }}
