Working tools for storage architects, SAN admins, and performance engineers — the kind of thing I wished existed when I needed answers on a Friday night.
For SAN admins and performance engineers — the parameters that go wrong silently, and the math that explains why.
How the VMware Round Robin IOPS limit setting works, and why the default is wrong for most modern arrays. Visual explainer with real numbers.
Side-by-side comparison of LB-IOPS and LB-Latency path selection schemes in NVMe-oF environments — when each one wins, when it loses, and which to choose for your workload.
DRAID layouts, capacity planning, and cyber resiliency sizing — the arithmetic that should never be done in a half-remembered spreadsheet at 2am. Aligned with my work as co-author of the IBM Cyber Resiliency Redbooks.
"Spreadsheets weren't enough. Whiteboards weren't shareable. So I built these instead."
Each tool started inside a real customer engagement. Built to answer a specific question on a specific day, then refined into something reusable.New tools appear here as new problems appear in the field.
These tools answer general questions well. But architecture decisions involving DORA, cyber resiliency, or large-scale storage environments usually depend on context, dependencies, and operational realities no calculator can fully capture.
