Tips & Best Practices

Verify compatibility of signaling rates before performing conversions
Consider the need for framing or padding due to differences in granularity between units
Use conversion results as part of broader network configuration processes, not standalone protocol translation
Be aware that the tool applies to legacy parallel SCSI and SONET/SDH systems, not modern IP-based networks

Limitations

Conversion does not address protocol overhead or signaling incompatibilities
Granularity differences may require additional adjustments like padding or framing
Specific to legacy parallel SCSI and SONET/SDH networks, limiting use in modern IP-centric environments
