Is there any particular reason why the All Flash Profiles have at least 10 cores per processor and the Hybrid have more options like 6 cores, 8 cores, 10 cores, 12 core?
I would like an 8 core All Flash Profile but the lowest flash profile is 10 cores. I want to keep it to 8 core processors because of Oracle licensing. I would like to do all flash because of dedupe, ,compression, Raid5/6, better performance.
I am going to assume you are referring to vsansizer.vmware.com, if you are referring to something else then let us know.
This is likely for these reasons:
- All Flash nodes typically achieve higher IOPS/throughput and thus would assume higher correlating CPU/GHz to match/balance CPU vs Storage requirements (possibly aligned with an assumed average/median number and/or size of disks used per host).
- The potential available Ready-Node configurations that these theoretical configurations might be based on (e.g. All Flash for these might be optimized/designed for VDI and thus high base-CPU and Memory).
I was referring to vsansizer.vmware.com I would have thought there would have been some good use cases for 3.X Ghz vs lower 2.X Ghz. There are still a number of applications that benefit more for clock speed than numbers of CPUs or cores given to them and licensing issues.
I had a further look at this, it appears it is due to the configurations of the Ready-nodes being used by vsansizer as I noted previously, all 10+ cores for 'AF' series:
And yes, I totally agree - more variety would be great in this tool but it is designed to use Ready-node specs so it is limited by which of these are included for reference.
Using the tool in combination with/or manual calculations is likely necessary to calculate what you require here.
