10 Services from data-calc.x402tookit.com

Calculates usable capacity, storage efficiency, fault tolerance, write penalty, and rebuild read-error risk for RAID 0/1/5/6/10 and ZFS RAID-Z arrays.

Calculates how many units (servers, nodes, pods) are needed for a peak load at a target utilization, with N+k redundancy, plus utilization after failures and growth projection.

Computes queueing model metrics (utilisation, Erlang C probability, queue length, wait times, tail probabilities) for M/M/1 and M/M/c systems given arrival and service rates.

Calculates compound storage growth over time: projected size after N months, raw capacity requirements with replication and overhead, time to double, and months until storage is full.

Converts an SLA availability percentage into allowed downtime per day, month, and year, with optional series and parallel composition of components.

Applies Little's Law (L = λW) to solve for concurrency, throughput, or latency given any two of the three, and computes recommended pool sizes.

Calculates the number of trunks (Erlang B) or agents (Erlang C) needed to meet a blocking probability target or service level objective given offered traffic load in erlangs.

Compares common algorithmic growth classes (n, n log n, n², 2ⁿ, n!) at a given input size n, returning operation counts, estimated run times, and the largest n feasible within a time budget.

Breaks down serial stage latencies against a total target, computes per-stage share and slack, identifies the bottleneck, and quantifies tail amplification from fan-out parallelism.

Converts requests-per-second and payload size into Mbps bandwidth requirements, applying peak factor, protocol overhead, and link headroom checks.
