Control | Description |
Enable FCIP | Enables FCIP protocol. By default, FCIP is disabled. By default, RiOS directs all traffic on the standard ports 3225, 3226, 3227, and 3228 through the FCIP optimization module. Environments with RF-originated SRDF traffic between VMAX arrays might need additional configuration to isolate and optimize the DIFs embedded within the headers of the FCIP data payload. For details, see the SteelHead User Guide. |
FCIP Ports | Specify the FCIP ports. Optionally, you can add FCIP port numbers separated by commas or remove a port number. Don’t specify a port range. By default, RiOS directs all traffic on the standard ports 3225, 3226, 3227, and 3228 through the FCIP optimization module. Note: The FCIP ports field must always contain at least one FCIP port. |
Apply | Applies your settings. (If you have enabled or disabled FCIP optimization or changed a port, you must restart the optimization service.) |
Rules | Environments with GigE-based (RF port) originated SRDF traffic between VMAX arrays must isolate DIF headers within the data stream. These DIF headers interrupt the data stream. When the R1 Symmetrix array is running Enginuity microcode version 5875 or newer, manual FCIP rules aren’t necessary. In 5875+ environments, RiOS automatically detects the presence of DIF headers and DIF blocksize for GigE-based (RF port) SRDF traffic. To manually isolate the DIF headers when the R1 Symmetrix array is running Enginuity microcode version 5874 or older, you add FCIP rules by defining a match for source or destination IP traffic. The default rule optimizes all remaining traffic that has not been selected by another rule. It always appears as the last in the list. You can’t remove the default rule; however, you can change its DIF setting. The default rule uses 0.0.0.0 in the source and destination IP address fields, specifying all IP addresses. You can’t specify 0.0.0.0 as the source or destination IP address for any other rule. For details about rules, see the SteelHead User Guide. |
Add a New Rule | Displays the controls for adding a new rule. Displays the controls for adding a manual rule. Use this control when the R1 Symmetrix array is running Enginuity microcode version 5874 or earlier. |
Source IP | Specify the connection source IP address of the FCIP gateway tunnel endpoints. Note: The source IP address can’t be the same as the destination IP address. |
Destination IP | Specify the connection destination IP address of the FCIP gateway tunnel endpoints. |
Enable DIF | Isolates and optimizes the DIFs embedded within the FCIP data workload. |
DIF Data Block Size | Specify the size of a standard block of storage data, in bytes, after which a DIF header begins. The valid range is from 1 to 2048 bytes. The default value is 512, which is a standard block size for Open System environments. When you enable DIF, RiOS FCIP optimization looks for a DIF header after every 512 bytes of storage data unless you change the default setting. Open System environments (such as Windows, UNIX, and Linux) inject the DIF header into the data stream after every 512 bytes of storage data. IBM iSeries AS/400 host environments inject the DIF header into the data stream after every 520 bytes. This field is required when you enable DIF. |
Add | Adds the manual rule to the list. The Management Console redisplays the Rules table and applies your modifications to the running configuration, which is stored in memory. |
Remove Selected | Select the check box next to the name and click Remove Selected. |
