IOPS / Throughput Converter

Two quick converters for the numbers that come up in capacity and replication planning.

MB/s ↔ IOPS

Block size (KiB) Throughput (MB/s) — leave empty to convert from IOPS IOPS — leave empty to convert from MB/s

Enter either throughput or IOPS.

Formula: IOPS = MB/s × 1024 / block size (KiB). MB/s = IOPS × block size / 1024.

SnapMirror catch-up estimator

How much sustained throughput do you need to move (or catch up) a dataset within a time window?

Data size to transfer (TiB) Time window (hours) Transfer efficiency (1.0 = raw bytes, 1.3–2.0 with compression/dedupe-friendly data)

Enter data size and a time window.

Formula: MB/s = TiB × 1,048,576 / (hours × 3600) / efficiency. This is a planning estimate — real SnapMirror throughput depends on network, source load, and change rate.

Reality check A 10 GbE link carries ~1,100–1,200 MB/s of application payload at best. If the estimator demands more than that, you need link aggregation, compression on the relationship, fewer/smaller snapshots, or a longer window.
