Chapter 1: System Description
Best Practices
It is important to note that the design of the DXi will not allow a virtual tape cartridge to be written to it if its
size is larger than the amount of free space available on the DXi. For example, if you have a virtual tape
cartridge size of 400 GB but only 300 GB of free space is available on the DXi, the backup will fail when
attempting to write data to the virtual tape cartridge. As a result, smaller virtual tape cartridge sizes are
better.
Remember, the DXi system is always cautious of being filled up so that the integrity of stored data is not
compromised.
