The single-queue storage I/O path for AHV VMs, which leads to the iSCSI redirector. AHV Turbo goes around it.

Terms in this definition
- General-purpose v1
The older storage account kind (
Storage), which lacks access tiers, Archive and premium file shares and retires on 13 October 2026. Converting to ZRS requires first upgrading to GPv2, a one-way change. - PATH
Parent-child hierarchies in DAX rely on this function. For each row it builds one delimited text value listing the IDs of the row's ancestors, top level first and ending with the row's own ID, which PATHITEM, PATHLENGTH and friends can then pick apart.
- Nutanix AHV
The hypervisor from Nutanix. Veeam's integration backs up its VMs to repositories and can restore to it from backups of vSphere, Hyper-V, AHV and other platforms.
- Virtual machines
Infrastructure-as-a-service compute giving complete control of the operating system, making it a fit for lift-and-shift moves and for software relying on OS-level pieces like COM.
- iSCSI redirector
Steers logins towards a working Stargate, ideally the local instance. Every AHV host runs this process, and QEMU treats it as the iSCSI target portal.
- AHV Turbo
A route for storage traffic on AHV that skips QEMU and spreads work over several queues. VMs get more storage I/O for less CPU.
Related terms
- KVM
Hypervisor that, combined with QEMU, offers one way to run Foundation as a standalone VM.
