The following table provides definitions for some of the terms that are used in this document:
Term | Definition |
AppsON | A PowerStore X model appliance feature that enables running applications as virtual machines directly on PowerStore storage and compute. This integration brings applications closer to storage. |
Controller VMs | Virtual machines that run a virtualized version of the PowerStoreOS on PowerStore X model appliances. Each PowerStore X model node has its own controller VM. Each controller VM reserves 50% of the available CPU and memory on the appliance, leaving the other 50% for user VMs. |
Distributed Resource Scheduler (DRS) | A VMware feature that monitors resource utilization and spreads virtual machine workloads across ESXi hosts in a cluster. |
Fibre Channel (FC) protocol | Protocol used to perform Internet Protocol (IP) and SCSI commands over a Fibre Channel network. |
Internet SCSI (iSCSI) | A mechanism that provides access to block-level data storage over network connections. |
NVMe over Fibre Channel (NVMe/FC) | Protocol used to perform Non-Volatile Memory Express (NVMe) commands over a Fibre Channel network. |
NVMe over TCP (NVMe/TCP) | Protocol used to perform Non-Volatile Memory Express (NVMe) commands over an Ethernet network. |
PowerStore Manager | An HTML5 user interface used to manage PowerStore systems. |
Storage container | A VMware term for a logical entity that consists of one or more capability profiles and their storage limits. This entity is known as a VMware vSphere Virtual Volumes (vVols) datastore when it is mounted in vSphere. |
Storage Policy Based Management (SPBM) | Policies used to control storage-related capabilities for a VM and ensure compliance throughout its life cycle. |
User VM | A virtual machine that is deployed by the administrator. A user VM can be using PowerStore storage with external compute hosts. A user VM can also be deployed using PowerStore storage and internal compute hosts by using AppsON. |
Virtual machine (VM) | An operating system running on a hypervisor, which is used to emulate physical hardware. |
vCenter | A VMware server that provides a centralized platform for managing VMware vSphere environments. |
VMware vSphere Virtual Volumes (vVols) | A VMware storage framework that allows VM data to be stored on individual Virtual Volumes. This ability allows for data services to be applied at a VM level of granularity and according to SPBM. Virtual Volumes can also refer to the individual storage objects that are used to enable this functionality. |
vSphere API for Array Integration (VAAI) | VMware APIs that improve ESXi host utilization by offloading storage-related tasks to the storage system. |
vSphere APIs for Storage Awareness (VASA) | VMware vendor-neutral APIs that enable vSphere to determine the capabilities of a storage system. This feature requires a VASA provider on the storage system for communication. |
vSphere cluster | A group of ESXi hosts that are grouped to enable high availability, load balancing, and resource management. |
vSphere datacenter | A container that consists of hosts, clusters, and other objects required to operate virtual machines. |
vSphere Remote Office Branch Office (ROBO) | A VMware license with a limit of 25 virtual machines. |
