Monitoring System Performance
Feature
• Hitachi Performance Monitor feature
With business infrastructures constantly growing more complex, companies
need the knowledge, skills, and tools to quickly identify potential
bottlenecks in each element of the infrastructure and take corrective action,
preferably before a problem becomes severe enough to be noticed.
Performance Monitor is an essential tool for planning and analysis of storage
resource requirements. It provides detailed, in-depth storage performance
monitoring and reporting of your Hitachi Simple Modular Storage 100,
including drives, logical volumes, processors, cache, ports, and other
resources. It can help you achieve and maintain service-level objectives for
performance and availability, identify storage performance bottlenecks, and
maximize the utilization of your storage assets. Performance Monitor’s in-
depth troubleshooting and analysis reduce the time to resolve storage
performance problems.

Supported Topologies
Your Hitachi Simple Modular Storage 100 is designed to provide disk storage
for use by your host servers. At its front end, your Hitachi Simple Modular
Storage 100 uses the iSCSI protocol over Ethernet to connect to iSCSI HBAs
or NICs installed in your server. This connection can be a direct, point-to-
point connection or a switched configuration through an IP storage switch
(also known as a “fabric”).
At its back end, your Hitachi Simple Modular Storage 100 contains six,
eight, or 12 internal SATA or SAS drives. The drives are preconfigured for
RAID 6 and are not intended to be removed from the array. Two spare drive
slots are provided for adding capacity, for a total of 12 drives and 9 TB of
storage.
