1 Displaying GSLB information

TABLE 10 Global SLB site information (Continued)

This field...	Displays...
Preference	The numeric preference value for this site ServerIron ADX. The
	preference can be used by the GSLB policy to select a site. Refer to “Site
	ServerIron ADX’s administrative preference” on page 11.
	This information is configured on the GSLB ServerIron ADX.
Location	The geographic location of the ServerIron ADX. The location is based on
	the ServerIron ADX’s management IP address and can be one of the
	following:
	•	ASIA
	•	EUROPE
	• N-AM: North America
	• S-AM: South America
	NOTE: If you explicitly identified the geographic location, the value you
		specified appears instead of a value based on the IP address.
		Refer to “Configuring a site” on page 19.
Virtual IPs	The virtual IP addresses (VIPs) configured on the ServerIron ADX.
	This information is reported by the site ServerIron ADX.
	The letter in parentheses at the end of each address indicates whether
	the ServerIron ADX is an active or standby ServerIron ADX for that
	address. The letter can be A (active) or S (standby). Unless the
	ServerIron ADX is configured along with a partner ServerIron ADX for
	Symmetric Server Load Balancing, the value is always A.
	If a number appears following the A or S, a host range (the unlimited VIP
	feature) is configured on the VIP. The number indicates the number of
	hosts in the host range.
	NOTE: The GSLB ServerIron ADX does not necessarily provide global
		SLB for all the VIPs configured on the site ServerIron ADXs. The
		GSLB provides global SLB only for the VIPs that correspond to
		the DNS zone names you configure the GSLB ServerIron ADX to
		load balance.
Connection Load	The average load at each connection-load sampling interval in the most
	recent set of sample intervals.

In the example above, the connection load metric is configured to use six samples, at 5-second intervals. The sampling intervals and the average new-connection load at each interval are shown. On this site ServerIron ADX, the average new-connection load for the last five seconds is 36, the average new-connection load for the last 10 seconds is 34, the average new-connection load for the last 15 seconds is 32, the average new-connection load for the last 20 seconds is 31, and so on. Any time you enter the command for this site ServerIron ADX, the average load for the last 30 seconds is shown.

Generally, remote ServerIron ADXs in a GSLB configuration are themselves configured with real servers and virtual servers. The real servers are the actual file servers for which the remote ServerIron ADX provides load balancing. The virtual servers are the logical IP addresses that are published instead of the real server IP addresses.
