ESS Expert
The IBM StorWatch Enterprise Storage Server Expert (ESS Expert) is an optional
software feature of the IBM StorWatch Expert. The StorWatch Expert can be
purchased to use with the ESS. The StorWatch Expert Web interface provides
storage-resource management for the IBM storage servers.
v
Asset management
StorWatch Expert collects and displays asset management data on all of your
ESSs.
v
Capacity management
StorWatch Expert collects and displays capacity management data on all of your
ESSs.
v
Performance management
StorWatch Expert collects and displays performance management data on all of
your ESSs. For example:
– Number of I/O requests
– Number of bytes transferred
– Read and write response time
– Cache usage statistics
The IBM StorWatch Expert allows you to schedule the information collection. With
this information, you can make informed decisions about volume placement and
capacity planning as well as isolate I/O performance bottlenecks.
Service interface
The ESS provides service interface ports for external connection of a service
terminal.
IBM or your service provider can perform service on the ESS by using an IBM
mobile service terminal (MoST) or equivalent.
Remote services support
The ESS service interface also provides remote service support with call-home
capability for directed maintenance for service personnel.
You provide an analog telephone line to enable this support. The service interface
provides an RS232 connection through a modem switch and modem to the analog
telephone line.
You need to order a modem and modem switch. The first ESS you order requires
this equipment. The modem and modem switch support up to seven ESSs. The
cable length from the ESS to the modem switch should be a maximum of 15 m (50
ft.).
The ESS provides the following service functions:
v
Continuous self-monitoring initiates a call (call home) to service personnel if a
failure has occurred. Because service personnel who respond to the call know
about the failing component, the service personnel can reduce the repair time.
v
Error and problem logs are available that service personnel can access remotely
to analyze potential failures.
v
Remote support allows the ESS to correct many types of problems. When the
ESS reports a problem, service personnel can often correct the problem from a
remote location.
