• Congestion Control Option
Specify whether to enable or disable the use of "The New Reno Modification to TCP's Fast Recovery
Algorithm" for controlling congestion in the target port. Select "Enable" when using the congestion
control option. When not using the congestion control option, select "Disable". It is not necessary to
change the default setting (Enable) for normal use.
● iSCSI Settings
• iSCSI Name
Input the iSCSI name of the target port.
Click the [Default] button to set the default iSCSI name.
The following input conditions apply:
- Alphabetic characters (lower case) and numeric characters
- Symbols "-" (hyphen), "." (period) and ":" (colon)
- The name starts with "iqn." or "eui."
- 4 - 223 characters
• Alias Name
Input the Alias Name of the target port.
While the iSCSI name is a formal nomenclature that specifies the target iSCSI port, an Alias Name is
used as nickname.
An Alias Name that is the same as another port cannot be specified.
The following input condition applies:
- Up to 31 alphanumeric characters
● General Settings
• VLAN ID
Select whether to "Enable" or "Disable" the VLAN ID for the target port.
When "Enable" is selected, specify the VLAN ID between 0 and 4095.
• MTU
Specify the MTU size of the target port.
"Maximum Transmission Unit (MTU)" is the maximum amount of data that can be transmitted at
the one time over the communication network.
The following input conditions apply:
- When "IP Version" is "IPv4": 576 - 9000 bytes
- When "IP Version" is "IPv6" or "IPv4 / IPv6": 1280 - 9000 bytes
When "Disable" is selected, the path may be unstable or blocked due to factors such as the path
bandwidth or the switch buffer size. However, if a long transmission delay occurs, performance
may be improved. Perform sufficient verification of the network environment before specifying
"Disable" for the congestion control option.
The same iSCSI name cannot be set to multiple iSCSI ports except the iSCSI name of the ETERNUS
DX Disk storage system.
