Performance Information Management

The ETERNUS DX Disk storage system supports a function that collects and displays performance data via
ETERNUS Web GUI or ETERNUS CLI. The collected performance information shows the operation status and
load status of the ETERNUS DX Disk storage system and can be used to optimize the system configuration.
Performance information can be collected such as host I/O information (IOPS values, throughput values,
respond time, cache hit rate), QoS information (IOPS values, throughput values, delay time), and the usage
information of CMs (CPUs) and drives.
ETERNUS SF Storage Cruiser or ETERNUS SF Express can be used to easily understand the operation status and
load status of the ETERNUS DX Disk storage system by graphically displaying the collected information on GUI.
ETERNUS SF Storage Cruiser can also monitor the performance threshold and retain performance information
for the duration that a user specifies.
For details, refer to the manuals of ETERNUS SF Storage Cruiser and ETERNUS SF Express.
