We bought two 3580-H23s for each of systems, a our 730-2067 (4-way) & a 830-2400 (2-way) last summer. Ultrium2, 200GB native, etc. as everyone else has said. I bench-tested the backup speed on both systems and got 70GB/hour on the 730 and 203GB/hour on the 830. The machines are comparable in CPW (2000 & 1850 respective) but the PCI-type bus made a world of difference. The saves were performed on non-dedicated but fairly idle systems, so the numbers could fluctuate a little. The save was of our JDE data libraries and not the entire system. Throughput is somewhat less when saving the entire system, but it's still way faster than the drives they replaced. Also, we are currently getting the entire system save on a single tape with room to spare. H23s are all that can be attached to an SPD box like our 730. The reason we went with H23s vs. L23s on the 830 was that the LVD tape controller required V5R2 and we just weren't ready to make that jump yet as we had app issues holding us back. A quick question for other LTO2 users: How much data have you gotten on the tapes before it asks for volume 2 of a save? IOW are you getting the normal advertised 2-1 compression or something different? On our old BCC AIT drives we would always get about 3.8-1 overall and I'm wondering if I can expect the same from the LTO2s (760ish GB/tape compressed).
