In my limited experience with DD (Data Domain) and DLM (emulated virtual tape) the issues we had was time to replicate and since we wanted the less-expensive solution we shared our DD with the distributed systems. We replicated to a local DR site, over black fiber and to a DR site almost 800 miles away, many issue getting the bandwidth even after the initial replication was complete, I forget how much data we were replicating but it was not the entire 8870 we had. at DR we had support issues because at the time there was one person, maybe 2 in the US that knew anything about DD and DLM configuration, we were left at DR with no support till the last minute, there were some replication issue that should not have been replicated, also fighting for I/O with the distributed folks, they had to shut down most of their TSM servers to allow us to get any I/O thru put. most if the issue I think were related to trying to get a good solution for the cheapest price. I would hope EMC has more support folks for this solution on the mainframe.

A bigger bigger reclaim time to get dataset available to mainframe, and very expensive. I need to store about 240TB in cloud and cost quiet project. We buy more midrange storage and save a lot of money and get a much more fast reclaim time to get dataset available to restore.

That's simple: a company sells no tapes. Only disk systems. What can they claim? BTW: real tapes, on foreground or just background of some VTS are really give way to disks. >From the other hand, spinning disks give way to SSDs. SSDs disks (more exactly: SSD with disk interface) give way to flash systems... -- Radoslaw Skorupka Lodz, Poland ====================================================================== -- Treść tej wiadomości może zawierać informacje prawnie chronione Banku przeznaczone wyłącznie do użytku służbowego adresata.
