Network Appliance is leading the WAN optimisation controller (WOC) segment of the application acceleration market, according to a recent global Gartner report.
The vendor captured 20.2 per cent of the 2004 global revenue share.
Regional percentages were not available, research director of Enterprise Communications and author of the Gartner report, Joe Skorupa, said.
However, NetApp's director of marketing and alliances, Mark Heers, said this figure was mirrored in the Australian market.
"Although we don't have specific figures, we are confident that our ANZ sales are on par with NetApp's global market share," he said.
WAN optimisation controllers were becoming more popular as companies centralised their servers and deployed Web-enabled intranet applications, Skorupa said.
Packeteer and Stratacache followed Netapp's market share closely on 20 per cent and 19.3 per cent, respectively.
Designed specifically for network deployment, NetApp's portfolio of NetCache products is targeted at companies that require content delivery and web optimisation rather than NetApp's traditional services of data storage.
Heers said they were aimed at improving the performance of corporate application systems such as CRM and ERP.
"NetCache optimises speed by caching recently read web pages, similarly to how our storage products cache recently read records," he said. "While our storage products can be applied to home users and businesses of all sizes, the NetCache products are more suited to large enterprise and ISPs."
The NetCache products are deployed by a number of major Australian ISPs including Telstra, Optus and iiNet.
