Just to be clear. The throughput of the plain vanilla PCI bus is 133
Mega BYTES/second (AKA 133.3 MB/s (note the big "B")). That is total
throughput. Translate that to bits (little b) it is 1,067 Mbps.
So getting 4 * 35 Mbps (140 Mbps) throughput should not be a major problem.
Getting 4 radios to work in close proximity would probably be a major
problem.

Hi Josh
Thanks for the info.
Is that 133mbps full duplex throughput? Or only 65mbps full duplex?

Pci shouldn't be a problem, but asking 35 megs per radio might be.

Hi Josh
Would a PCI to 4 port mPCI card adapter with 4x Radio's be able to get at
least 133Mbps throughput?
I am looking at purchasing an Intel Atom and adding 4x Radio cards but I'm
worried about the performance of the PCI card
Thanks

Anyone using these?

It is getting much harder to find a board with this many PCI slots.
Maybe Mikrotik needs to make a PCI Express card.

It even has a PATA / IDE port for you DOM. Why use a hard drive that
has moving parts. It will eventually fail.
Anyone know the bus limitations on PCI? Can a PCI port even transfer
4 gigabits per second?

I'd recommend this way also (building / buying x86 boxes).
There's a good thread on the MT forums from a guy who was quite happily
running 10Gbps interfaces on Dell PowerEdge 860's back in v3.X

Hi,
I would build my own x86 based Mikrotik boxes with as many GigE ports
as you need (or use multiple boxes). You can build a much more
powerful system for the same or less money than an RB1100.
Even the ATOM processor based Supermicro boards have a LOT more
horsepower, and some come with two GigE ports right on the board.

We have an office complex where we have wired up 15 offices.
Typically, we put in as many RB493s tied together as it takes, with
each available port doing NAT/DHCP on a separate network.
In this case, we have fiber to the building, and we have gigabit
access to Radiological Images, where a series of images can be quite
large.
So, having gigabit to each customer unit is required to "do it
right".
Obviously, I want something that can handle some pretty good "bursty"
traffic. I would guess that only one or two units would actually be
doing the big transfers at one time, but I want them to be
super-fast...
kinda get in, get the data, get done..
My considerations thus far have been a RB1100.
Is there a better/faster/cheaper way to do this?
