Validate Hardware for Vsphere 8.0

Dear all,

Thank you for visit this port. I need to help me validating hardware virtualazition, i have total 160 vcore and 1,1TB RAM. I want build 3 nodes running HA with config: 2 x CPU 44 core, 768GB RAM on per node.

Please help me check this configure.

Use this tool to check system and IO device compatibility for ESXi: https://www.vmware.com/resources/compatibility/search.php

Thanks sir. i need to check if each node 44 core/cpu can meet 160 vcore total? And is there any tool to calculate from core => vcore ?

Hi,


Excuse me, explain for a moment what it means, in your opinion, to validate the physical hardware against vSphere 8 according to "160 total vCPUs".

Ferdinando

Hi Sir, i want build 3 node Server VMware 8.0 to running all VMs with total VMs (160 vCore + 1,1 TB RAM).

I would say that 3 nodes running HA with config: 2 x CPU 44 core, 768GB RAM on per node should comfortably satisfy your requirement and have enough capacity to enable you to replace or maintain one host whilst the load runs temporarily on the others.

Oh, so a capacity planning “validation”.

Hello,

 

Based on your hardware specifications, you have a total of 160 vCores and 1.1TB of RAM. You would like to build 3 nodes running in a High Availability (HA) configuration, with each node having 2 CPUs (44 cores) and 768GB of RAM.

Considering your requirements, let's calculate how many nodes you can set up and the resources available for each node:

  • CPU Cores: Each node requires 44 CPU cores, so 3 nodes would require a total of 132 cores. Since you have 160 vCores available, you have enough cores to meet this requirement.

  • RAM: Each node requires 768GB of RAM, so 3 nodes would require a total of 2,304GB (2.3TB) of RAM. However, you only have 1.1TB of RAM available, which is not sufficient to allocate the desired amount of RAM to each node.

Given your current hardware specifications, it is not possible to configure 3 nodes with 2 CPUs (44 cores) and 768GB of RAM each. You would either need to reduce the RAM requirements per node or consider upgrading your hardware to accommodate the desired configuration.

It's worth noting that these calculations are based on the assumption that all available resources are dedicated solely to these nodes. In practice, you may need to allocate resources for other purposes, such as the underlying virtualization platform, management overhead, or additional VMs. Make sure to account for those factors when planning your infrastructure.

Best regards

I believe he says that each node has 2 cpus, each with 44 cores, so 88 cores a node 264 cores total. The nodes all have 768GB of RAM, so total of 2.3TB. The load on the other hand is 160 vcpu and 1.1TB RAM. So it should comfortably fit on those 3 nodes :slightly_smiling_face:
