Atom C2758 vs Xeon D



  • Hey fellas, how's it going

    I'm looking to replace my Zotac CI323 nano. It's got 16gb ram, 250gb 250 samsung evo. I run pfblocker,squid,clamav,openvpn, l2tp ipsec on it without problems. CPU usage is hardly any and memory never goes above 10%. Network has about 4 wired devices and about 4 wireless ones. My current line is ADSL2+ 11mbit down 1up.  That means i have an old copper telephone line running into ADSL modem which is bridged into pfSense ci323 and then a network switch.

    In the future i was thinking about running a NAS server and will be upgrading to Docsis 3.0 cable line, which means my download will be 100-120mbit and up 2mbit. I realized i could do this with one BOX and save on power bill and having to run another box separately for FreeNAS.

    Would supermicros atom c2758 be suitable for the job? Plan is to run esxi on one machine either c2758 or one of the embedded Xeon D's like 1528 and up+ then setup freenas and pfsense on it

    The c2758 option only has x2 SATAIII and x4 SATAII. With 4 mechanical drives in SATA2 it shouldn't matter, right? It would be noticeable on SSD's, right?

    The Xeon D option has a more SATAIII ports and also 10gbe PORTS etc. Honestly, i am not worried about anything above 1GB WAN. Australia will not see 1GBe internet 100 years from now.

    Any input or advice is appreciated, thanks.



  • They're both a waste of money, you'd be better off with an AM1 platform such as the AM1ML (coreboot compatible) it would be $60 for cpu+mobo, add a pci-e server pull nic ($10) and you're good to go.

    Having a supervisor processor present on a networking device is a massive security risk, the AM1 doesn't have ME/PSP and it also has a socketed eeprom chip which means you can do cool stuff like stick the pfsense embedded install entirely on the motherboard with no drives attached.

    Running a daemon on a router is a security risk.

    The benefits you notice from SSD's is all related to latency not raw throughput at all, unless you transfer files on a connection over 1gbps.



  • Actually that does look promising, just for pfsense.

    Am i able to chuck in Athlon 5350 into that motherboard? How does Athlon 5350 compare to my current Celeron N3150. Does it have AES-ni? I'm keen to try it just for a project/fun anyway.

    If so you should use some kind of virtualization to keep the two functions separated for security reasons.

    One disadvantage with combining the functions on a single hardware is that administrative work on the host OS and/or virtualization software may affect your internet connection. A dedicated firewall generally means less internet downtime.

    With 4 mechanical drives in SATA2 it shouldn't matter, right?

    Correct, SATA revision 2.0 (3 Gbit/s) isn't a bottleneck with mechanically rotating disks.

    The Xeon D option has a more SATAIII ports and also 10gbe PORTS etc. Honestly, i am not worried about anything above 1GB WAN. Australia will not see 1GBe internet 100 years from now.

    1 Gigabit networking have since long been a NAS bottleneck. 10 GbE will be very useful on the LAN (regardless of internet connection speed) when there are affordable switches available.

    It is an AM1 CPU, so of course you can put it in an AM1 motherboard.
    It is way better, twice as fast.

    Yes it does have aes-ni.



  • keep the ci323 for your pfsense and build a proper bare metal freenas box with ecc ram - xeon d and atom with ecc are fine, if not overkill, for those

    thanks for suggestion, sounds like the right step.

    i want to give ci323 another chance, i would like to try realtek's driver from their website and have started a new threat asking how to do it.

    ci323 is giving me random "stalls" on network. not sure if it's package related or driver that comes with freebsd/pfsense



  • The Atom C2758 OR the Xeon 1528 should be better if yo are planning to go virtual. Both have enough processing power to run your freenas and pfsense and still have enough power to spare for additional vms if needed and should able to handle future upgrades

    If I were in your place, I would go for the Xeon 1528 with Intel NICs and be done with it. No matter what anyone says, running old processors still consumes a good amount of electricity. The Atom and Xeon will save you on electric costs as well. Realtek NICs are ok but still not reliable as Intel.

    It's an N3150, the C2758 and the D1528 will both draw more power…

    I'd personally go with messerchmidt and split the functionality; taking your internet connection down to screw around with a NAS VM is annoying. Leave the firewall on the CI323 and just never think about it.
