A、 the use of physical LTO-5 drives and cartridges for virtualization reduces the overall floor spacerequired for the virtual tape solution 

B、 the virtual tape solution reduces the number of cartridges and physical drives required, andimproves throughput 

C、 the virtual tape solution provides a faster robotic access to virtual cartridges sent to the physicaltape librarywhich guarantees faster accesstimes 

D、 the virtual tape solution provides a larger range of virtual tape drives and automates the backupprocess to physical tape by full synchronousreplication
