IT Toolbox

IT Calculators

Quickly estimate transfer time, RAID capacity, backup requirements, SLA downtime and more.

⇄

File transfer time

Estimate the time required to transfer a data volume at a given throughput.

Size

Throughput

↔

Storage unit converter

Quickly convert between decimal and binary storage units.

Value Unit

▦

RAID capacity

Estimate usable RAID capacity for a set of disks.

Level RAID Number of disks Capacity per disk (TB)

⟳

Backup storage requirements

Estimate backup storage based on initial size, daily changes and retention.

Initial volume (GB) Daily change (%) Retention (days) Safety margin (%)

✓

Availability SLA

Convert an availability percentage into maximum allowed downtime.

Availability (%) Time range

≡

Log storage requirements

Estimate the volume required to retain system or SIEM logs.

Events per second Average event size (bytes) Retention (days)

▣

Virtual machine sizing

Calculate the total resources needed for identical virtual machines.

Number of VMs vCPU per VM RAM per VM (GB) Storage per VM (GB)

Decimal / binary / hexadecimal

Convert an integer between common numeral systems.

Value Input base

⌁

Bandwidth per user

Estimate the bandwidth available per concurrent user.

Throughput Internet (Mbit/s) Concurrent users Infrastructure reserve (%)

◷

Required backup throughput

Calculate the minimum theoretical throughput for a backup window.

Volume to back up (GB) Window available (hours) Estimated overhead (%)

Key point: These results are technical estimates. Actual performance depends on compression, protocols, latency, disk speed, deduplication and system load.
