SimpliVity terminology
The following table contains SimpliVity terms and definitions.
Term
Definition
Arbiter
SimpliVity software that runs on the computer hosting the hypervisor
management server or a different Windows computer that the OmniStack hosts
can access. It is required in every SimpliVity Federation. The arbiter provides
the tie-breaking vote when a cluster contains an even number of OmniStack
hosts. For example, if a cluster contains two OmniStack hosts and one of those
OmniStack hosts loses connectivity with the cluster, the arbiter acts as the
tie breaker. (Note that an arbiter must not run on any host within a cluster for
which it is acting as a tie breaker.) (Previously referred to as an OmniCube
Arbiter.)
cluster
A collection of OmniStack hosts that share resources and provide high
availability and load-balancing services.
datastore
A container for virtual machine files, including compute and storage resources.
For more information, refer to your hypervisor documentation.
failure domain
A collection of OmniStack hosts that serve as potential high availability failover
targets for each other for purposes of high availability and disaster recovery.
Federation
A collection of SimpliVity OmniStack hosts and clusters managed in a single
globally-unified management domain.
guest operating
system
The operating system that runs inside a virtual machine.
host
A generic term referring to either an OmniStack host or a standard host.
OmniCube host
See OmniStack host.
OmniStack Accelerator A SimpliVity PCI card that provides non-volatile memory, accelerated
compression, and cryptographic hashing. The Accelerator card communicates
with the OmniStack software.
OmniStack host
A host (server) containing an OmniStack Accelerator card that communicates
with the OmniStack software and some supported virtualization software. An
OmniStack host uses a dedicated virtual machine called the OmniStack Virtual
Controller, which runs the OmniStack software. (Previously referred to as an
OmniCube host.)
