Mellanox chops 10-gig Ethernet switch, adapter prices

Mellanox Technologies is not happy about the 10 Gigabit Ethernet switch and adapter ramp, and it is doing something about it: slashing its own prices. In the wake of its acquisition of InfiniBand switch-maker Voltaire, Mellanox last year launched its SwitchX converged Ethernet and InfiniBand ASICs for 10GbE and 40GbE switches …

WTF?

What the foo?

'"There is definitely demand for 10GE, but it has been limited by high cost," Gilad Shainer, '

This guy gets paid to figure that out?

Milking it for all it is worth

Rather like waiting for CPU speeds to increase

like it

I checked performance figures for SX1035 and it's quite amazing.

I wish I could make a small network with such stuff at home ;)

Under $400 for 10Gbps adapter - well I think that goes long way towards increasing adoption.

Sir

If you are able to generate that level of traffic on a home network, you will quickly start finding other bottlenecks that are harder to overcome, such as disk write speeds

4x Infiniband

4x (ie 10Gb/s) dual port IB cards can be had on ebay for less than $50. So a point to point network between 3 or 4 machines with IPoIB and some routing magic is not expensive.

I did this with three such cards and three PCs. I measured 5.8 Gb/s testing with netperf, and upwards of 300 MB/s NFS file server operations (limited by my RAID array).

I do not run MPI code at home, so I think getting DDR or QDR cards would be overkill, but 10Gb/s IB proved to be very enabling, very much faster than gigabit Ethernet.

"300 MB/s NFS file server operations (limited by my RAID array)"

I think that is a protocol limit, you should be able to push that up to around 350 using ftp.

NDA agreements.

Slight case of RAS syndrome methinks.
