Performance Information Management

The ETERNUS DX supports a function that collects and displays the performance data of the storage system
via ETERNUS Web GUI or ETERNUS CLI. The collected performance information shows the operation status and
load status of the ETERNUS DX and can be used to optimize the system configuration.
Performance information that can be collected includes host I/O information (IOPS values, throughput val-
ues, response 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 can be used to easily understand the operation status and load status of the
ETERNUS DX by graphically displaying the collected information on the GUI. An administrator can also use
ETERNUS SF Storage Cruiser to monitor the performance threshold and specify how long performance infor-
mation is retained.

Device Time Synchronization

The ETERNUS DX has a clock function and manages time information of date/time and the time zone (the
region in which the ETERNUS DX is installed). This time information is used for internal logs and for functions
such as Eco-mode, remote copy, and remote support.
The automatic time correction by the Network Time Protocol (NTP) is recommended to synchronize time in
the whole system.
When using the NTP, specify the NTP server or the SNTP server. The time correction mode is Step mode (im-
mediate correction). The time is regularly corrected every three hours once the NTP is set.
