Dual network ports
Hey all,
I got a Ultra 60 and I'm going to put a quad fast ethernet card into it, also I have a NAS with dual ethernet ports. I'm going to setup the Ultra 60 as a gateway to the NAS.
Is it possible to setup 2 ports on the quad fast ethernet card to talk to the 2 ports on the NAS? Both using the same IP and the computer thinking that it is all one port not 2?
OR
Is it possible to setup the Ultra 60 and NAS so that one port is used for incoming data and the other for out going data. Thus having a 100Mbit connection each way to and from the NAS to the Ultra 60?
If either of these two ways or both are possible where cas I find some documentation on how to set it all up?
Thanks.
Oh yeah the Ultra 60 will be running Solaris 8 and the NAS well that has some Micro version (kernel) of linux (So I have been told).

cmdide
CMDIDE(4) BSD Kernel Interfaces Manual CMDIDE(4)
NAME
cmdide -- CMD Technology and Silicon Image IDE disk controllers driver
SYNOPSIS
cmdide* at pci? dev ? function ? flags 0x0000
options PCIIDE_CMD064x_DISABLE
options PCIIDE_CMD0646U_ENABLEUDMA
DESCRIPTION
The cmdide driver supports the CMD Technology PCI0640, PCI0643, PCI0646, PCI0648, PCI0649, and Silicon Image 0680 IDE controllers, and pro-
vides the interface with the hardware for the ata(4) driver.
The 0x0002 flag forces the cmdide driver to disable DMA on chipsets for which DMA would normally be enabled. This can be used as a debugging
aid, or to work around problems where the IDE controller is wired up to the system incorrectly.
SEE ALSO
ata(4), atapi(4), intro(4), pci(4), pciide(4), wd(4), wdc(4)
BUGS
There's no way to reliably know if a PCI064x controller is enabled or not. If the driver finds a PCI064x, it will assume it is enabled
unless the PCIIDE_CMD064x_DISABLE option is specified in the kernel config file. This will be a problem only if the controller has been dis-
abled in the BIOS and another controller has been installed and uses the ISA legacy I/O ports and interrupts.
The PCI0646U controller is known to be buggy with Ultra-DMA transfers, so Ultra-DMA is disabled by default for this controller. To enable
Ultra-DMA, use the PCIIDE_CMD0646U_ENABLEUDMA option. Ultra-DMA can eventually be disabled on a per-drive basis with config flags, see
wd(4).
The timings used for the PIO and DMA modes for controllers listed above are for a PCI bus running at 30 or 33 MHz. This driver may not work
properly on overclocked systems.
