We have the following: 2 X FAS3020s controller, attached to about 20TB storage. We are installing HBA card (2GB) into each Filer and Attaching LTO3 drive to each. Backup is TS3310 with 4 drives. I cannot attached more drives to FAS.
I am looking for someone that has some first hand experience with LTO3 & NETAPP, that can provide me with some real world throughput stats on the LTO3.
