  1. Finally got it working. IP addresses were fine. The issue seems to be that there's a conflict if you use Auto Metric under the Advanced properties of the IPv4 settings for each adapter you have. I set the 1Gb NIC (with Internet access) to a Metric of 1, and the 10Gb (no Internet access) to 9999 and it seems to work. @Endeavor01 From 1GbE onward you don't need crossover cables. They autosense.
  2. desktop is 192.168.1.42 for 1Gb (Internet) and 192.168.2.42 for 10Gb server is 192.168.1.69 for 1Gb (Internet) and 192.168.2.69 for 10Gb Ethernet adapter Slot04 x16 3 (10Gb): Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::64f2:39a1:3dfb:74a2%5 IPv4 Address. . . . . . . . . . . : 192.168.2.42 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : Ethernet adapter Ethernet (1Gb): Connection-specific DNS Suffix . : Link-local IPv6 Address . . . . . : fe80::5cf0:3d8f:e0ab:14b3%3 IPv4 Address. . . . . . . . . . . : 192.168.1.69 Subnet Mask . . . . . . . . . . . : 255.255.255.0 Default Gateway . . . . . . . . . : 192.168.1.1
  3. Apologies in advance if this is obvious, but still learning networking. Been researching a lot but not finding a solid answer. I have a home network (1Gb wired plus wifi) with Internet access. I'm trying to have a second separate network between my desktop PC and a sever. Both are on a 1Gb switch/router that has Internet access on the 192.168.1.X subnet. My desktop and server both also have 10Gb Ethernet NICs and are connected with a direct network cable (no switch). Both report link is up and are showing 10Gb speed. Both have static IPs on the 192.168.2.X subnet. There is no default gateway or DNS set for these adapters. (I am running Win10 on both at the moment) But, I am not able to ping or connect between the desktop and server using the 10Gb connection. Is it because Windows has set it to a Public network? Do I need to change the routing tables?

  4. Picked up a couple of the Mellanox Connectx-2 VPI cards (MHQH29C-XTR) Can I use QSFP+ transceivers with this so that I am ready to move up to a ConnectX-3 later, or must I stay with a regular QSFP transceiver for now?
  5. Did a bunch of research. Depending on my workflow I may end up needing a more powerful server down the road (e.g. Supermicro X9QR series), but thought I'd start with something more economical and see how much use I'm getting out of it. Ended up ordering a Rosewill B2 Spirit full ATX case (Super ATX size?). Has 13 drive bays and will support motherboard of HPTX at least, so should handle my oversized board.
  6. Thanks. I'll look into both options. Trick is to find one that will take a motherboard this big, otherwise maybe I need to buy a complete server (not as fun) The noisiest component probably won't be CPU fans, but the 7000 rpm fan on the RAID card. It's a custom heatsink/fan combo for the ROC chip that's around 40mm. Not sure how to cool that in a quieter way
  7. I'm working on a server build that will be part NAS and part render machine. I've got Intel S2600IP motherboard with 2 x E5 Xeon 6-core processors and 32GB ECC RAM. The board is quite large - custom size of 14.2" x 15" 12 x HGST 4TB 7200RPM SATA HDD 2 x Intel 80GB SSD Areca 1882xi RAID Controller (also 2 x LSI 9211-8i so I can try FreeNAS) Full height Mellanox 10GbE NIC This motherboard was designed to work with the Intel S4000 Pedestal server case, but also works in server chassis. I've looked at Norco 4224, but reviews complain about unreliable backplanes and sub-par build quality. X-Case has nice cases, but I don't see them available in the US. Supermicro seems to have decent chassis but can be quite pricey. We live in an apartment, so this will probably be in a corner in our kitchen. I don't want it to be too loud. Being able to use my existing ATX PSU would also be nice. Any suggestions?
  8. Lol. That I knew. I was thinking whether I could use some kind of rubber grommet or even rubber bands
  9. I recently picked up a surplus Intel S2600IP motherboard with two CPUs and passive Intel 4U server heatsinks. This is for a home server, so I'd like it to be quiet. I think it will take an 80mm fan, but how would I mount it?
  10. I determined that I needed about 20 meters. Pre-terminated 20m cables are pricey. I decided that I would get optical transceivers and some LC-LC OM3 duplex multimode fiber, as it was quite a bit cheaper that way. Hopefully it should work!
  11. I'm planning to get a couple of Mellanox Connectx-3 VPI 40Gb Ethernet/56Gb IB network cards. When it comes to active optical cables (QSFP+), if the cable is rated for 40Gb, will it also handle 56Gb IB? For example, this cable: http://www.ebay.com/itm/Arista-Compatible-AOC-Q-Q-40G-15M-40G-QSFP-Active-Optical-Cable-AOC-15meters-/172630647034?hash=item283196a0fa:g:JPMAAOSwax5YoLv3
  12. I have a feeling it would work with Linux, as Linux seems to have drivers to even the most exotic and old. But, it's probably not worth the hassle. If it's hard to find drivers now, it'll be even harder down the road.
  13. Yeah, I was thinking that. It's not like I'm going to build a fiber channel SAN, and Ethernet seems to have won the race. Reminds me of the very old days of token ring. Shows my age!
  14. Awesome catch! These test benches are really nice. Thinking I should upgrade mine. Wonder if they have US sellers?
