RE: FC speeds

Buy the faster card while the checkbook is open! (:

Rob, what's the combined throughput of all of the backups running at once? Will that fill 8GB?

Yes, the 16GB cards will step down to 8GB. No worries there, However,

The 16GB card is easily twice the price of the 8GB card, so if you can't
use it, why buy it?

then the other question is if this is driving tape or VTL, are they that
fast? Answer no. LTO8 is not running at those speeds yet.

Apparently when we go from Power 8 to Power 9 we're upgrading from 8GB FC

The 16GB is supposed to have the smarts to dial down as needed.

Our SAN and it's inserts are currently limited to 8GB FC. Scheduled to
upgrade perhaps next year.
Then there's our EMC DD 2500. I believe that's limited to 8GB FC. True?

I don't believe we're really pushing the speed here but I wouldn't mind
being surprised and that it is possible to be even faster.
We do save from multiple lpars at once into that DD.
Although the TSM on the AIX lpar using lan and not FC.
