Hi Leigh! We also choose a VTL solution (EMC's DL700) over a SATA box with a file device class because IBM couldn't come up with a reference site of similar size (180 TB) with a file device class. The only statement we could get from IBM was: "It will most likely work"... By the way, we are very happy with the virtual library concept and so are our customers. Kindest regards, Eric van Loon

It is a decision that I am trying to come to terms with myself and have not yet settled in my mind which I prefer. Apart from price, if you take into consideration ease of management/configuration and performance, what decision making processes did those 2 variables lead you through. Did you go with IBM TS7510 or EMC CDL or a n other ? I guess the last $64M question is, are you happy with the decision you made ?

Easy to set up if your offsite location is within fibre distance. Only we are putting the VTL (primary pool) OFFSITE and the 3584 (copy pool) ONSITE. Why? 1) Tapes jam. Drives break. The 3584 is very reliable, but still mechanical. Easier to have it onsite, near us, to manage. The VTL is essentially lights out, so it will live offsite. 2) IF we have a disaster, having the VTL offsite means we can do DR restores without being limited by the number of tape drives we have. Cool idea, huh? Means we only need 2 drives in our 3584. Collocation & tape mounts are no longer an issue. And another cool thing: 3) We're even putting a spare Windows server offsite with the VTL, and making it a backup domain controller. TSM is already installed on it, but inactive. If we have a disaster, all we have to do is restore the TSM DB. We can start restoring files then to any machine we can get IP connectivity to. Our domain is still up, we don't have to recover AD. I can hardly wait for the tornado!

We would locate the 3584 in our offsite storage location and access it via fiber. The tapes would remain in the 3584 since they would already be offsite. Anyone have any experience with a setup like this?
