Shipments should start very soon (on July 31, 2009). FICON Express8 is

I just read through a lot of the announcement letter from the link quoted

channels cost, but I know if you just bought your machine, and you decide
you need those channels, you it will probably cost a lot to convert. I

I doubt if the new channels will be significantly more expensive if you buy
them with a new machine. If you just took delivery of your machine 2 months
ago, and then realize these chanells could help because you have a huge DASD
farm, you might be talking significant dollars, although if you ha

Radoslaw,
That's not necessarily true. If you are using something other than the DS8K
storage from IBM you will probably see an improvement in single channel
throughput because the bottleneck on the channel is at the host end, rather
than the storage port. There will also be an advantage for where
Mileage will vary on this. The most interesting part of the announcement to
me is that the link speed increase is only part of the story. There seem to
be other changes in the adapter and elsewhere that improve performance,
both with and without activating the link speed boost.

Tim,
Flashdrives are not going to make any surprising leaps and bounds due
Channel performance. The concurrent throughput of Flashdrives is limited by
the Back-end topology of each vendor's storage, and has very little to do
with the Host Channel connections to cache. If a customer wants/needs to
