Then HA will calculate how much resources are currently reserved for both memory and CPU for powered-on virtual machines. For CPU, those virtual machines that do not have a reservation larger than 32Mhz a default of 32Mhz will be used. For memory a default of 0MB+memory overhead will be used if there is no reservation set. VMware host failures clusters admission control policy. Here is an excerpt from the document. Slot Size Calculation. Slot size is comprised of two components, CPU and memory. VSphere HA calculates the CPU component by obtaining the CPU reservation of each powered-on virtual machine and selecting the largest value. If you have not specified a.
*Vmware Ha Slot Size Calculations ChartVMWare vShpere Slot Calculation What is SLOT?As per VMWare’s Definition,’A slot is a logical representation of the memory and CPU resources that satisfy the requirements for any powered-on virtual machine in the cluster.’If you have configured reservations at VM level, It influence the HA slot calculation. Highest memory reservation and highest CPU reservation of the VM in your cluster determines the slot size for the cluster.Here is the Example,If you have the VM configured with the highest memory reservation of 8192 MB (8 GB) and highest CPU reservation of 4096 MHZ. among the other VM’s in the cluster, then the slot size for memory is 8192 MB and slot size for CPU is 4096 MHZ. in the cluster.If no VM level reservation is configured , Minimum CPU size of 256 MHZ and memory size of 0 MB + VM memory overhead will be considered as CPU and Memory slot size.Calculation for Number of Slots in cluster :-Once we got the Slot size for memory and CPU by the above method , Use the below calculationNum of CPU Slots = Total available CPU resource of ESX or cluster / CPU Slot SizeNum of memory slots = Total available memory resource of ESX or cluster minus memory used for service console & ESX system / Memory Slot sizeLet’s take a Example, I have 3 host on the cluster and 6 Virtual machine is running on the cluster and Each host capacity as followsRAM = 50 GB per HostCPU = 8 X 2.666 GHZ per hostCluster RAM Resources = 50 X 3 = 150 GB - Memory for service console and system = 143 GBCluster CPU resources = 8 X 2.6 X 3 = 63 GHZ (63000 MHZ) of total CPU capacity in the cluster - CPU Capacity used by the ESX System = 60384 MHZI don’t have any memory or CPU reservation in my cluster, So, the default CPU slot size 256 MHZ and one of my Virtual machine is assigned with 8 vcpu and its memory overhead is 344.98 MB (which is the highest overhead among my 6 virtual machines in the cluster)Let’s calculate the num of CPU & Memory slotsNum of CPU Slots = Total available CPU resource of cluster / CPUSlot size in MHZNo of CPU Slots = 60384 MHZ / 256 MHZ = 235.875 ApproxNum of Memory Slots = Total available Memory resource of cluster / memory Slot Size in MBNum of Memory Slots = 146432 / 345 = 424 ApproxThe most restrictive number among CPU and Memory slots determines the amount of slots for this cluster. We have 235 slots available for CPU and 424 Slots available for Memory. So the most restrictive number is 235.So, Total number of slots for my cluster is 235 Approx. Please find the below snapshotPlease refer my blog post on Understanding Total Slots, Used Slots & Available slots in VMware HA Slot to understand Total Slots, Used Slots & Available slotsI hope you understand the post..Thanks For Reading !!!!!Vmware Ha Slot Size Calculations Chart
