You can also change to an aggregate context that applies to multiple server instances, that allows
you to display and modify the parameters for all the server instances. For example, you could
change to an aggregate context for the three server instances in the previous example above
using a command like the following:
eqcli >
srvpool sp01 si sv01,sv02,sv03
eqcli sp-sp01-si-sv0*>
The CLI is now in the aggregate server instance context “
sv01,sv02,sv03
” -- only the first three
characters of which are displayed in the command line. To see the entire context name, use the
context
command:
eqcli sp-sp01-si-sv0*>
context
The context is “sv01,sv02,sv03”.
eqcli sp-sp01-si-sv0*>
In an aggregate server instance context, the
show
command will display the configuration of all
the server instances in the context.
Load Balancing Policies
Equalizer supports the following load balancing policies, each of which is associated with a
particular algorithm that Equalizer uses to determine how to distribute requests on a server pool
in the cluster:
Load Balancing Policy
Description
round robin
round robin
load balancing distributes requests on the server pool
in the cluster. Equalizer dispatches the first incoming request to the
first server, the second to the second server, and so on. When
Equalizer reaches the last server, it repeats the cycle. If a server in
the cluster is down, Equalizer does not send requests to that server.
This is the default method.
The round robin method does not support Equalizer’s adaptive load
balancing feature; so, Equalizer ignores the servers’ initial weights
and does not attempt to dynamically adjust server weights based on
server performance.
static weight
static weight
load balancing distributes requests among the
servers depending on their assigned initial weights. A server with a
higher initial weight gets a higher percentage of the incoming
requests. Think of this method as aweighted round robin
implementation. Static weight load balancing does not support
Equalizer’s adaptive load balancing feature; Equalizer does not
dynamically adjust server weights based on server performance.
