Monitoring the storage
NOTE: The storage hardware structure is not identical for all models. The terminology and elements
shown on the Storage Cluster section of the Hardware tree may be slightly different depending upon the
model that you are using.
This section contains a list of storage clusters.
The name of the cluster clearly identifies the couplet to which it belongs, such as Couplet 1 Storage
Cluster 1. The Storage Controller identifies the Name and Type of Monitoring Host. This relates to the
server or node on which the Active Management Console is running.
Each storage cluster contains the following items:
• Drive Enclosures: The following installed hardware components are included under the tree hierarchy
for each enclosure:
◦ Drive: The physical hard disks. See Drives (enclosure) on page 126.
◦ Fan
◦ I/O module
◦ Power Supply
◦ Temperature Sensor
• Pools: The number of pools shown depends on the base storage and the number of capacity
expansion kits installed.
• Controllers: This confirms the controller information for the controller card associated with the storage
cluster. The name of the controller links back to the Storage Controller item in the Server section of the
Hardware tree. The following installed hardware components are included under the tree hierarchy for
each storage controller:
◦ I/O cache module
◦ Port
◦ Super Capacitor

This page provides details about the status of the hard disks within the head unit or enclosure. The status
is either OK or Failed. This page also provides buttons to switch the disk's Beacon LED on and off.
