Re: Offsite library via fiber (Specifically VTL)
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.

Re: Offsite library via fiber
Our only real natural threat is a tornado and we are told by our risk assessment guys that the odds of one tornado hitting both buildings are about 2 million to 1. On top of that the Data Centers are designed to survive an F3 tornado and continue to operate. We are not near any military targets or any hazardous chemical plants. So the odds of an unnatural event are also low. There is risk in everything, sometimes the UPS guy stops for coffee and leaves the truck running. There are longer range plans to take another copy and move it 30km away.

Re: Offsite library via fiber (Specifically VTL)
Actually, it IS just a big chunk of SATA disk with sequential files, not a "formal" VTL. I should have explained, I was using "VTL" the concept, not "VTL" a product! But I"ll give you my thinking, anyway: Advantages to using a VTL(the product): * The VTL software does compression for you. We have to set up our clients to do compression. If your client data isn't already compressed, and you are MOVING existing data from tape back to a pool of disk - it's gonna expand again. (We've been using client compression for the last year because I was planning for this.) * more of a "drop in" and forget it solution, less setup knowledge required (probably not an issue for very experienced TSM admins) Advantage of having "just a pool of disk" * probably more flexible in terms of being able to expand at will. We can add-replace drawers with bigger drives. We can add to our solution with disk from a different VENDOR if we want. My past experience is that the more generic and expandable your hardware solution, the longer you are able to get return on the investment. * I'm not jazzed that several of the VTL's on the market use software that comes from a from a 3rd party (shades of Emc buys Clarion buys Legato buys OTG etc. Just don't want to go there. Don't' want to have to think about what happens to my support 3 years from now.) BUT, our decision actually was determined by some VERY UNIQUE requirements we have for purging sensitive data if we need to. We create smaller LUNS than most people would so that we can segregate them and replace chunks of disk physically when we need to. (Don't ask.) In other words, we wanted more control over the internal placement of data. I think depending on your installation, either can be an excellent solution. If you need something relatively small, drop in, VTL is a better way to go (with a VENDOR YOU TRUST TO BE AROUND FOR A WHILE). If your shop doesn't have TSM skills, or time to think about it, a VTL is a better way to go If you are growing very fast, understand the technology, and need something with a lot of expandability, I would look more at building your own solution from building blocks you can be flexible with (and a VENDOR YOU TRUST TO BE AROUND FOR A WHILE). My opinions and nobody else's..

Offsite library via fiber
We're thinking of a TSM upgrade that would include a VTL onsite library and an IBM 3584 library for copy pool tape. 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? Daivd Ehresman University of Louisville
