Click [ Next > ]. The Device window (advanced mode only) appears. The Device window
enables you to define how many data streams are allowed simultaneously and how many
files are kept in a directory. The options are detailed below.
Enter the following in the Device window:
Field
How many data streams
are allowed at a time?
How much memory
should be used for each
data stream cache?
Directions
Select Hard Disk.
Enter a name for the Vault, or use the default if the field
is already populated.
"Data streams" refers to how many connections can be
made to a Vault simultaneously. Having several
connections enables several clients to communicate with
the Vault simultaneously, so the more streams you permit
the greater the requirements for processing power.
This setting defines how much virtual memory is set aside
for incoming and outgoing data during file storage and
retrieval. A larger cache may improve performance but will
do so at the expense of using more virtual memory. The
total amount of space used equals the number of data
streams multiplied by the selected cache size. So, if you
select 10 data streams and 10 MB of cache, the Vault will
set aside 100 MB of total virtual memory for caching data.
A selection of 10 MB is usually sufficient.
