Questions about Sizing and Requirements for "Compute Only" Clusters with Pure Storage

Hello, everyone.During the last Nutanix .NEXT event (05/07/2025), the partnership between Pure Storage and Nutanix was announced, enabling the use of Compute Only (CO) clusters integrated with Pure's FlashArray. (https://blog.purestorage.com/news-events/pure-storage-solution-with-nutanix/) When accessing Sizer, I still haven't found a specific option for pure "CO" where I can combine nutanix+pure. So I did the way I found, I selected "CO + SO", I can't exclude the nodes with "Storage Only" function, which makes it difficult to simulate the desired scenario. I would like to understand a few things, if anyone knows and can contribute with information:→ How to perform the correct sizing for "Compute Only" clusters integrated with a Pure Storage FlashArray? → Is it possible to configure Nutanix hosts with zero local disks, relying 100% on Pure's external storage? → Is there a recommended or supported limit of CO hosts per FlashArray? (example: I need at least 3xCO+Pure to ensure functional

Nutanix All Nvme sizing

Hi All, I am very new to Nutanix. I am looking to size our environment on Nutanix platform which is currently on VMware. I am looking to size 50TiB of storage in the Nutanix cluster(3 node cluster at beginning) and how many disk are need for achieving so. The cluster will be all NVMe. Does Nutanix need cache disk for All NVme cluster as well like VSAN OSA or it’s same as VSAN ESA. I will be very grateful for any suggestions or link for correct documentation. Thank You

Collector: Questions on vCPU/CPU calculation and calculated CPU count

Hi! I have two doubts related to Collector´s vcpu and cpu calculation.1) I couldn't find the information on the vcpu/cpu ratio per VM in Collector's Excel spreadsheet? Please, how is it calculated when we perform workload upload per VM? 2) In Sizer, I performed a manual modeling from Collecto´s Excel spreadsheet information as a “Raw Input” and compared it to the automatic per VM-upload modelling.In the analyzed scenario, the customer has 440 CPU Cores distributed in 19 physical servers/hosts in the current environment (vhost table information)  My calculations/modelling for a “Raw Input” is the same for the overall resources calculated by the automatic per VM upload (RAM, Datastore), except for the total o CPU cores in the cluster.The automatic per-VM upload/calculation was performed with the following settings: As result, the workload was modeled with 552 CPU cores:  Please, why does the per-VM upload have 100 more CPU cores than the existing customer´s environment (552 vs 440 from t

Splunk Workload Ingest per Indexer

I am curious why when sizing a Splunk workload and increasing the performance profile for the indexers it doesn’t increase the ingest rate per indexer rather than keeping it at 100 GB.  By not doing this, it keeps the same number of indexers Nutanix thinks it needs even though each indexer has more CPU/RAM.  I could be missing something simple here, but I would like to hear other thoughts.Capacity Planning Manual: Summary of performance recommendations
