Performance Information Management - Fujitsu ETERNUS DX500 S4/DX600 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 ena-
bles 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 Advanced Copy (EC/REC/OPC/SnapOPC/SnapOPC+).

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.
ETERNUS SF Storage Cruiser can be used to easily understand the operation status and load status of the ETER-
NUS 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 displayed, from ETER-
NUS Web GUI. The performance information, which can be obtained, are indicated 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)
•
Extreme Cache Hit Rate
•
●
Volume Performance Information for the Advanced Copy Function
• Read IOPS (the read count per second)
Write IOPS (the write count per second)
