Insufficient resources error despite available resources

[Sahaya Jestus Lazer]

Hi,

This is something that happens often in fabric. While creating a slice, even though there are available resources, fabric throws “Insufficient resources : [core, ram]#” which results in the slice not getting created. Am I missing something?

Sincerely, Jestus

Hi Jestus,

This error occurs when the host capable of provisioning the requested resource has run out of cores and RAM. While the resource view provides cumulative information for the entire site, checking resource availability at the host level offers more precise insights. This is available on the portal for each site resource view and also can be checked via API as shown by list_hosts in example here.

It’s possible that the combination of requested components (such as NICs or GPUs) maps to a host without sufficient cores or RAM, leading to the error you’ve encountered.

We have an example notebook  (Additional Options: Validate Slice) available that allows you to validate resource availability beforehand using the API, which can be helpful prior to submitting a slice. Additionally, we’re working on changes to the allocation policy to better distribute VMs across hosts. This will help ensure that CPUs, RAM and disk are not fully allocated on single host which has SmartNICs and GPUs, minimizing such errors. These updates are planned for deployment in the January Release and should improve resource allocation.

Thanks,
Komal
