De LoadMaster 4000 Load Balancer is een geavanceerde application delivery controller met Layer 7 content switching en geïntegreerde ASIC-gebaseerde SSL versnelling. De LoadMaster verdeelt gebruikersverkeer intelligent en efficiënt en ontlast en versnelt Layer 7 toepassingen zoals SSL beveiliging en -inhoud, om web- en toepassingsservers te optimaliseren zodat gebruikers de best mogelijke ervaring krijgen. De LoadMaster 4000 geeft IT administrators meer controle en stelt hen in staat om zich gemakkelijk aan te passen aan netwerkwijzigingen door een optimaliseringslaag voor systeemelementen van toepassingen en servers ter beschikking te stellen. De LoadMaster 4000 garandeert dat iedere gebruiker de best mogelijke ervaring krijgt door 99,999 % hoge beschikbaarheid van toepassingsservers te bieden en elimineert de Server Load Balancer als single point of failure. De LoadMaster vereenvoudigt het management van systeemonderdelen in een netwerk en optimaliseert en versnelt de gebruikerstoegang tot verschillende servers, inhoud en transactiegebaseerde systemen. De LoadMaster 4000 levert een unieke combinatie van beschikbaarheid en prestaties voor kritieke servers en toepassingen.
