What does SCSI (Async) mean?

SCSI (Async) refers to the asynchronous data transfer mode of the Small Computer System Interface where data is exchanged using request/acknowledge handshakes rather than synchronous timing.

What is STS1 (payload) in SONET?

STS1 (payload) is the user data capacity inside an STS-1 frame, with a line rate of 51.84 Mbps and a usable payload capacity of 50.112 Mbps.

Why convert SCSI async throughput to STS1 payload?

Converting SCSI async rates to STS1 payload helps translate legacy device performance into standardized optical transport capacities for network provisioning and comparison.
