Virtualization & Private Cloud Calculators
25 free virtualization & private cloud calculators in Cloud.
- Cluster Expansion CalculatorFind when a virtualization cluster hits its utilisation threshold and when to order hardware given procurement lead time.
- Host Failure Impact CalculatorQuantify a host failure: VMs affected, capacity lost, post-failure utilisation, restart window and the availability cost.
- Hypervisor Consolidation CalculatorWork out how many hypervisor hosts replace a fleet of physical servers, and the capex and power that consolidation changes.
- Infrastructure Utilization CalculatorScore CPU, memory, storage and network utilisation together to find stranded capacity and the annual cost of the waste.
- OpenShift Cluster Health CalculatorScore OpenShift cluster health from node readiness, pod failures, etcd fsync latency, API latency and degraded operators.
- OpenShift Node Capacity CalculatorTurn raw node CPU and memory into allocatable capacity after system-reserved, kube-reserved and the eviction threshold.
- OpenShift Pod Density CalculatorCompare the 110 default and 250 maximum pods per node against the 4-pods-per-vCPU guideline and your DaemonSet overhead.
- OpenShift Project Quota CalculatorTotal ResourceQuota requests and limits across projects and read the resulting cluster overcommit ratio.
- OpenShift Registry Storage CalculatorSize the internal image registry from image streams, tags retained, shared base layers and daily build churn.
- OpenShift Route Capacity CalculatorSize the OpenShift ingress router: routes and connections per router pod, TLS handshake rate and connection-limit utilisation.
- OpenShift Upgrade Time CalculatorEstimate an OpenShift upgrade window from operator rollout, serial control-plane updates and worker drain and reboot waves.
- OpenStack Cinder Storage CalculatorConvert Cinder volume demand into raw backend capacity including Ceph replication, snapshot deltas and a free-space reserve.
- OpenStack Keystone Resource CalculatorEstimate Keystone identity load: users, role assignments, service catalog endpoints and token validations per second.
- OpenStack Neutron Network CalculatorPlan Neutron tenant networks: usable addresses per subnet, port counts, floating IP demand and VXLAN segment usage.
- OpenStack Nova Capacity CalculatorSize Nova compute capacity using the cpu and ram allocation ratios, reserved host memory and a chosen flavor.
- OpenStack Swift Storage CalculatorSize a Swift object ring: raw capacity for the replica count, drive count, object count and partitions per drive.
- Virtualization Ratio CalculatorMeasure the three ratios that describe a virtual estate: VMs per host, vCPU per core and allocated versus physical memory.
- vMotion Network CalculatorSize vMotion bandwidth and estimate live-migration time from VM memory, dirty-page rate and concurrent migration limits.
- VMware Cluster Capacity CalculatorTotal up a vSphere cluster's usable CPU and memory after failover reservation and see how many average VMs it carries.
- VMware Datastore Capacity CalculatorSize a VMFS or NFS datastore for VMDKs, swap files, snapshot growth and the free space vSphere needs to stay healthy.
- VMware HA Capacity CalculatorCheck vSphere HA admission control: how much capacity a percentage or N+1 slot policy reserves and whether restarts actually fit.
- VMware Memory Overcommit CalculatorMeasure ESXi memory overcommit and see which reclamation stage it triggers: page sharing, ballooning, compression or host swap.
- VMware vCPU Overcommit CalculatorCheck your vCPU to physical CPU ratio against workload-appropriate limits and read it against observed CPU ready time.
- VMware VM Density CalculatorWork out how many VMs an ESXi cluster really holds once CPU overcommit, host memory overhead and per-VM VMX overhead are applied.
- vSAN Storage CalculatorConvert vSAN raw disk capacity into effective usable capacity after RAID overhead, slack space and dedupe or compression.
