I have a customer who backs up a data amount of about 500 GB with 2 Jobs
each day on a 2-drives-3590 with DSS. Because of data growth, he has now
problems with his batch window. His 3590 (A50/B11) is connected to his R36
by one escon channel. During the backup the channel is completely busy. I
have thought about a quick method to drop down the backup time by connecting
a second channel. Is this possible and would this help him. He has
experienced, if he runs only one job at a time, the backup time of this
single job is significantly faster. Therefore I assume, that a second
channel could help him.
Yes, as a quick fix, that is a good idea. the data rate of a 3590-B11,
after compression, is higher than the rate of an ESCON channel, so it is
not surprising that it maxes out the channel. Since he is writing to 2
tapes, a second channel will help.
Better long term fix is FICON channels
