S-AIT / Qualstar
Are there any opinions out there about the Qualstar's new S-AIT
library? I'm somewhat surprised there is not more discussion about it on this list and on the web in general. The 500 GB native capacity was very appealing for my group, however we're having trouble with bugs in the firmware for the drive. I'd be interested to hear experiences from those who have purchased the S-AIT drive. And also, for those who have considered it but chose a competing product, what your reasons were. Or let me ask it this way: if you were building a new data center from scratch and needed to backup 40 machines (around 10 TB total) incrementally, on a nightly basis, would you chose Qualstar's TLS-5000 series? Why or why not? thanks in advance, -a |

Why or why not? thanks in advance, -a Sony has just announced mass lay-offs, including most or all of it's IT sales force in the USA. Their commitment to S-AIT is questionable to say the least. As another poster already suggested, LTO-2 is a much better bet for your environment. Depending on your *restore* requirements, your backup may not be optimal if you try to cram many backup streams onto a single large medium. Plan carefully when selecting your technology, you may find that you're better off with multiple LTO-1 drives. Since you mention you'll be doing incremental, you will also need to know how much of the 10TB changes. plugCheck out our Exabyte Magnum-20. Plenty of capacity, and your choise of LTO-1 or LTO-2, Fibre, SCSI or both/plug Rob |

I would go with IBM LTO-2 drives. StorageTek has good high end drives and libraries, but not in the 10 TB range, LTO-2 = .2TB/cart (without any compression factored in) = 50 carts for 10TB. They have the rack-mountable L80, which would be large enough for a single copy of your backups. Or, the L180 is serious enterprise-class robotics and would probably be the right size for 10TB LTO-2 with multiple copies + slots to make an off-site copy. & Quantum just released their SDLT600 drives (300GB native / 600GB compressed) while STK owns the high end market (for now), both Quantum & Overland (the mid market leader & private labelled by both IBM & HP) are just starting to deliver 500-700 cart libraries that can be connected together to compete with STK on the high end _____ . .
