RP4440

We have purchased two RP4440 with the following cards:
0/1/2 - Core LAN
0/4/1 - SCSI Adapter
0/4/2 - FC/Gigabit LAN Combo card
0/5/1 - FC/Gigabit LAN Combo Card
0/5/2 - FC/Gigabit LAN Combo Card
0/2/1 - Gigabit LAN card
0/6/1 - Gigabit LAN card

The server will be connected to EMC DMX Frame with 2 FC connections and one FC connection for SAN backup. The two servers will be configured in MC/SG with two lans (subnets) configured on each. Two lan cards will be standby for the two lans. One lan card will be a dedicated heartbeat lan.
Can you suggest the connections for optimum performance, considering shared and unshared slots...which cards can be used for SAN and cards that can be used for LAN...

Re: RP4440

As far as I am aware, paths 0/6 and 0/2 have the highest throughput. We have put our FC/Gb combo cards in it.
Paths 0/4/* and 0/5/* have the same architecture, but have a lower throughput as 0/6 and 0/2

Re: RP4440

Do you think we should swap the two Gigabit Cards with the Combo cards.

Re: RP4440

Hi,

Slots 7 and 8 are single slots. The maximum capability of each slot is PCI/PCI-X 133 MHz. Only slots 7 and 8 will allow 133 MHz, PCI/PCI-X cards to run at full speed. These two slots are not limited by bus-mode, frequency-related incompatibilities.
Slot 3 and 4 is the first pair of shared slots, and slots 5 and 6 are the second pair of shared slots. The maximum capability of each of the shared slots is PCI/PCI-X 66MHz. If a PCI/PCI-X 133 MHz card is placed in a shared slot, then the maximum capability the PCI/PCI-X 133 MHz card will run at is PCI/PCI-X 66 MHz.

As such, it is much better to put the 2 most important combo cards in slot 7 and 8. Those cards are 133MHz/64bit.

Regards,

Nico
