Critical evaluation:
Nutanix Volumes Block Storage is Nutanix’s scale-out block storage service built on Nutanix AOS / Nutanix Cloud Infrastructure (NCI) that exposes Nutanix Distributed Storage Fabric capacity as block devices (LUNs) via iSCSI and also supports attaching volume groups directly to VMs in Nutanix environments. It is designed to consolidate block storage for physical workloads, guest-initiated iSCSI, shared-disk clustering, and some container/Kubernetes persistent volume scenarios onto the same platform as Nutanix virtualization/HCI.
The vendor's marketing describes the product as suitable for enterprise deployments and highlights data services (for example, data reduction and DR features) and reduced dependence on external SANs.
