Difference in Performance Between NVMe Namespace and Associated Volume

[vemus]

Hi Team,

I recently created an NVMe Namespace, and during the process, an associated volume was automatically created. Below are the details:

• NVMe Namespace Path: /vol/namespace_nvme/namespace_nvme_1

• Associated Volume: namespace_nvme

I’m trying to understand the performance differences between the NVMe namespace (/vol/namespace_nvme/namespace_nvme_1) and the associated volume (namespace_nvme). Specifically, is the performance of the NVMe namespace the same as that of the associated volume, or are there key differences in how each performs?

Looking forward to your insights!

Thank you!

Think of it as a LUN/file on a volume

 Performance will at least be dictated by the underlying aggregate depending on aggregate type (NVme or SSD or sas or sata) will also have an impact on performance. The number of actively used volumes will have an impact also

hello:

         It is equivalent to the LUN of the FC and iSCSI protocols. Utilizing the NVMe protocol, the namespace can be accessed through multiple controllers. Most operating systems support NVMe drivers. Through this driver, the namespace of the solid-state drive will be displayed as a standard block device, on which file systems and applications can be deployed without any modification. You can identify the namespace by the name of the volume it belongs to. You can click on this name to display the volume details on the Performance/Volume Explorer page.

Best regards.
