<\/a>Load Balance<\/p><\/div>\n
\u00a0<\/a><\/p>\n Microsoft Network Load Balancing (NLB) is a very simple service.\u00a0 It distributes requests to the specified ports according to the configured weightage. It does not respond to the load on the nodes.\u00a0 It does however disable non responsive nodes within 5-7 seconds.<\/p>\n The FAQ on the NLB service is available here.<\/p>\n http:\/\/technet.microsoft.com\/en-us\/library\/cc758834%28v=ws.10%29.aspx<\/a><\/p>\n There are however several caveats.<\/p>\n Using NLB on a single NIC can have some problems.\u00a0 The hosts can\u2019t see each other inside the manager.<\/p>\n http:\/\/support.microsoft.com\/kb\/556067<\/a><\/p>\n A cluster that has at least one Windows Server 2008 node should only be managed from a computer running either Windows Server 2008 or Windows Vista\u00ae using Remote Server Management Tools (RSAT).<\/p>\n http:\/\/technet.microsoft.com\/en-us\/library\/cc753944(WS.10).aspx<\/a><\/p>\n http:\/\/technet.microsoft.com\/en-us\/library\/cc732855(WS.10).aspx<\/a><\/p>\n Configuring NLB for dual NIC.\u00a0 Using this method however will require substantial network redesign.\u00a0 It implies that the SQL servers need to be on a different subnet.\u00a0 The SQL servers in most cases are already operational, so\u00a0 are your users.\u00a0 The only way out is create a new subnet for your web hosts.\u00a0 ARrrggh.<\/p>\n http:\/\/support.microsoft.com\/kb\/268317<\/a><\/p>\n Configuring NLB for single NIC<\/p>\n
