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.

Thanks

1 to 3gb/m. with 1.5 to 2.5 the average.

A lot depends on the type of data.

We are looking at backing up a number of  LUN's, 5 TB each.

Actually I was talking about the files themselves.
Two extreme example from people I've worked with.
1) A hospital 3tb volume of 25-50k jpg files which were all scanned images of their paperwork.
2) a 1tb volume of mainly logs.
The first worst case for backup the second best.

In your case with a 2gb HBA going to each LTO3 you will be backing up at a rate that is as good as it gets.

A number of LUNs is rather vague but if you can not go more than four tape drives you might have a problem with your backup window. However figuring chances are you don't have to do a daily full backup you still might be fine. What some do with the larger amount of data is replicate it to secondary storage made up typically cheap SATA drives and then from the secondary it is moved to tape. This way operations are not impacted by the backup, but that might be more trouble and expense than you need.
