Actually we use SAN, if I remember correctly. :wink:
A storage area network (SAN) is a dedicated network that provides access to consolidated,
block level data storage. SANs are primarily used to make storage devices, such as
disk arrays,
tape libraries, and
optical jukeboxes, accessible to
servers so that the devices appear like
locally attached devices to the
operating system.
Network-attached storage (NAS) is file-level
computer data storage connected to a
computer network providing data access to a
heterogeneous group of clients. NAS not only operates as a
file server, but is specialized for this task either by its hardware, software, or configuration of those elements.
Actually you use a SAN to move data between the servers and one (1) or more NAS
The point of my post to the OP is...
You can use up to so much of the disk space ('part') - when your 'part' is full YOU need to remove files or get more space
The server has one (1) or more disk space ('part's) - when one becomes nearly full it will stop some or all tasks that use it - until that 'part' has more room
which has nothing to do with how much of your disk 'part' is used
