We have 3 520s in use. Each driving 8 Sdlt320 drives in separate L700 libraries and 2tb of diskpool(on DS series disk). We backup/archive between 2 and 3 TB a day. Haven't had any performance problems to date.

This server would be used exclusively for TSM backups. We back up about 1.5 TB every night. We have two tape libraries, one about 50 miles from here and one locally, where we send all the backup data (about 66 TB total). We have 8 tape drives locally and 5 tape drives at the remote library. Our database and storage pools are on our SAN. What do folks think about the p 570 performance vs. the p 520--better or worse? Has anyone made this same switch or is anyone using a p 520? If so, how are things going? What's your environment look like? Thanks! Nancy Brizuela, CPA Systems Programmer, Senior University of Wyoming IBM/Unix Systems Group Ivinson Room 238 (307)766-2958
