Two 4/40 Libraries to one Fibre Controller on K-Class

AstraZeneca Unix Staff — Mon, 04 Dec 2000 16:08:13 GMT

Is the above supported through HP SureStore E Hub L10 or Brocade 2400 if the two 4x40 have been upgraded to fibre using product #A5590A?

No. You'll have streaming problems
causing a corrupted backup.
Two hubs one host adaptor one lib.

I would not go for the hub solution. Streaming 4 drives over one loop (100MB/sec) might cause congestions and all sorts of other nasty problems.

The Brocade solution is a better one but I believe only Quickloop is supported at this time. Quickloop behaves like Loop but without the performance penalties that a real FC Hub would impose.

Hope this helps,

Cal.
