Multiple servers backing up on tape

Hi all,

We have tens of SQL Server instances and currently they perform regular log backup every 15 minutes.

So far we have been using disk based backups, for example on local disks of servers or shared storage on SAN.

Recently we decided to buy a tape.

My question is that what happens if for example 10 jobs on different servers try to write backup to tape?

Because on disk based backup, the disks of destination will become slow but never reject the backupset. Does the same thing happen for tape or the tape will reject the write operation if requests are too high?

Thanks in advance,

Leila
