Performance Information Management - Fujitsu ETERNUS DX100 S4 Design Manual

2. Basic Functions
Operation Management/Device Monitoring
■
ETERNUS SF
ETERNUS SF can manage a Fujitsu storage products centered storage environment. An easy-to-use
interface enables complicated storage environment design and setting operations, which allows
easy installation of a storage system without needing to have high level skills.
ETERNUS SF ensures stable operation by managing the entire storage environment.
With ETERNUS SF Storage Cruiser, integrated operation management for both SAN and NAS is
possible.
■
SMI-S
Storage systems can be managed collectively using the general storage management application
that supports Version 1.6 of Storage Management Initiative Specification (SMI-S). SMI-S is a storage
management interface standard of the Storage Network Industry Association (SNIA). SMI-S can
monitor the ETERNUS DX status and change configurations such as RAID groups, volumes, and Ad-
vanced Copy (EC/REC/OPC/SnapOPC/SnapOPC+).

Performance Information Management

The ETERNUS DX supports a function that collects and displays the performance data of the stor-
age 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.
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. ETERNUS SF
Storage Cruiser can also monitor the performance threshold and retain performance information
for the duration that a user specifies.
When performance monitoring is operated from ETERNUS SF Storage Cruiser, ETERNUS Web GUI,
or ETERNUS CLI, performance information in each type is obtained during specified intervals (30 -
300 seconds) in the ETERNUS DX.
The performance information can be stored and exported in the text file format, as well as dis-
played, from ETERNUS Web GUI. The performance information, which can be obtained, are indica-
ted as follows.
●
Volume Performance Information for Host I/O
Read IOPS (the read count per second)
•
Write IOPS (the write count per second)
•
Read Throughput (the amount of transferred data that is read per second)
•
• Write Throughput (the amount of transferred data that is written per second)
• Read Response Time (the average response time per host I/O during a read)
Write Response Time (the average response time per host I/O during a write)
•
Read Process Time (the average process time in the storage system per host I/O during a read)
•
Write Process Time (the average process time in the storage system per host I/O during a write)
•
• Read Cache Hit Rate (cache hit rate for read)
• Write Cache Hit Rate (cache hit rate for write)
Prefetch Cache Hit Rate (cache hit rate for prefetch)
