Hw/cpu needed to max out 1gb nic speeds


Post by gurkburk76 »

Hey, been using nas4free for a while now on some old hardware i had around ( x64-embedded on Intel(R) Core(TM)2 Duo CPU E7600 @ 3.06GHz + 6gig mem) and i'm getting about 50mb/sec with a zfs raidz1 pool of 3 discs and aes-128 software witch is ok i guess.

But to my question, i'de like to throw this into a new computer and i was thinking that if i get a amd (that has aes instructions) fx-6200 cpu + 16gig memory (this comp would then later also be used an an esxi server with the drives forwarded to the nas4free vm via direct io for some speed) it really should be no problem pushing the speeds of the 1gb card, ~115-120megs/sec. I mainly just wanted to know what kind of hardware other ppl are using to max out a 1gb connection with aes enabled on the drives :)

I was actually wondering if nas4free disk encryption will really use the aes HW capability of the recent processor as AMD FX ?
I have currently a system with a old Phenom II (without aes) and was thinking replacing it with a cheap AMD FX mainly
to have aes HW support (ans also a bit to lower consumption from 125 to 95 tpd), but before this I would like to be sure
it will work ? Any experience ?

Thank you

As you can see I have an AMD dual core as well as encryption (AES) plus RAIDZ1 pools. My best throughput when downloading a single file is nearly 40 MB/sec. I have never bested that. I had to get an intel NIC (Marvell and the on board Realtek were slower) plus Daoyama's ZFSKernTune to get to where I am now. CPU usage is near 100% (both cores) so there may be more I can do but it is in the depths of FreeBSD and device drivers which I am not that familiar with.

From everything I have read, especially back to FN7 when a group of people really tried to speed things up, I have never heard of throughput better than 100 MB/sec. There are lots of factors even outside of the NAS that can restrict these speeds. Good luck. :)

Maybe the system in my sig is something for you. I have also ZFSKernTune and I'm using it with HW-crypto of the CPU. I'm getting 67 MB/s write and 74 MB/s read through CIFS with SMB and AIO (works now in .636!) at ~60% CPU load. This doesn't max out the nasbox, but my AMD-E350 Sourcemachine which has also a crypted drive. :D

I haven't benched iscsi, but it would be interesting, because it is not limited to single thread, right?
