Typical Configuration

The 7190 can support data centers, whether or not they have an Intel Load Balancer. Without these Intel products, the 7190 can monitor site service availability by using an ISV method:

•Ping (ICMP)

•TCP Open probe

•HTTP URL probe

The 7190 can be used with a wide variety of topologies but a basic example of a 7190 configuration might consist of two 7190s and four NetStructure 7140s (one 7190 at each location that the site is distributed across, and two 7140s in serial fail-over mode for each location). For illustrative purposes, these devices are configured to balance www.mstd-ex.com. Because the 7190 does not resolve records aside from hostnames (e.g., no MX records or reverse DNS lookups), your existing DNS server should remain authoritative for the domain, mstd-ex.com. A new zone, zone.mstd-ex.com, must be created and your existing DNS server must delegate authority for this zone to all of the 7190s. An alias, www.zone.mstd-ex.com is created for www.mstd-ex.com. This zone and alias are transparent to users connecting to your site. They still requests www.mstd-ex.comand are referred to the optimal site by the 7190.
