T
Capacity allocated for thick volumes.
In virtual storage, thick provisioning is a type of storage allocation in which the amount
of storage capacity on a disk is pre-allocated on physical storage at the time the disk is
created, meaning that the volume has all its capacity pre-allocated on creation.
Capacity allocated for thin volumes.
Thin provisioning is a method of optimizing the efficiency with which the available space
is utilized in storage area networks (SAN). Thin provisioning operates by allocating disk
storage space in a flexible manner among multiple users, based on the minimum space
required by each user at any given time.
Throttling controls resource prioritization for rebuild and rebalance processes.
Throttling can be controlled per Protection Domain or per Storage Pool (by configuring
rebuild and rebalance policies).
The Tie Breaker (TB) is an MDM that does not have a manager role, whose sole
purpose is to help determine which MDM module is the manager that will become the
master MDM and take control over the VxFlex Ready Node cluster.
The Tie Breaker ensures that there will always be one Master MDM achieving cluster
quorum. In a 3-node cluster, there is one TB; in a 5-node cluster, there are two TBs.
U
Capacity that is not being used, but is also unavailable (due to server outage).
Capacity that is not currently being used for any purpose in the system.
V
A general term referring to a storage device. In VxFlex OS, a volume consists of multiple
blocks spread evenly on Storage Pool devices.
W
The full screen view can be minimized into a widget, which is a small window that floats
on your screen, over other applications. Property sheets can also be minimized into
widgets.
