I am trying to work out how to configure an F760 cluster and appear to be running out of slots. The main connection from the user community to the filer heads is via ATM, for a cluster I am told I need 2 ATM cards for each head in an active passive configuration, the passive connection taking on the identity of the 'failed' (heaven forbid) filer.
Now, due to the number of disks required for data storage I need two FCAL loops per filer, 4 required in each head for failover.
I need 1x 100Mbit ethernet connection to connect directly to a second cluster for mirroring and 2x 100Mbit direct connections to Unix servers for Oracle database access.
The F760 has 9 slots. I can use slots as follows:
Slot 1 Quad (or dual ethernet) Slots 2 and 3 for ATM Slots 4,6,7 for FCAL cards Slot 8 for Cluster Card Slot 9 for NVRAM
It appears I cannot use Slot 5 for any type of card other than a connection to a tape device!
Can I fail the ATM connection over to a 100Mbit ethernet slot, if I use a quad ethernet card then there would be a connection free. This would free up Slot 3 for the fourth FCAL card.
Does anyone have any ideas on this and how we can get it all to fit. Before anyone suggests it the answer is no I cannot look at the 840's just yet!
Thanks in advance David
