comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
@MichelZ yes. At least I damn well hope so - Server 2012 R2 and Windows 7 at either end.

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
@joeqwerty that calculator is great. When I'm back in the office tomorrow I'll muck around and see what's what. Right now it looks like my total packet size is going to be 1536 bytes, which is too big.

@MichelZ I have. Tried lots of different source/destinations with the same result

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
@joeqwerty well the problem probably did occur before the upgrade, but because it was a 10/10 link it was by coincidence capping out at the maximum available bandwidth anyway.

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
@joeqwerty The devices at both ends of the tunnel show 0 errors, 0 pause, a handful of underruns and nothing particularly out of the ordinary anywhere else.

1394 is the largest MTU that I was able to get through.

comment 20Mbps WAN limited to 10Mbps over IPSec Tunnel
Good point. It's 9000 on both the switches at either end, 1500 on the server and clients themselves, and 1480 on the VDSL portion of the link. That's the only portions of the links that I control.

comment infiniband network between 3 servers
Which I also mentioned - chaining them off each other. Never having used infiniband I wasn't sure if that was actually possible though, but then the nodes in the middle of the ring become a "switch" anyway. Maybe not a device sitting in a rack, but they still switch packets between nodes on the network.

Not sure what was wrong about my answer? I told him that he has to use a switch in the last paragraph.

comment Practical difference between SPARC vs x86
I believe that SPARC also scales out better than x86 does. I've seen big iron SPARC machines marketed with 1024 cores at > 3GHz. Good luck getting that on x86.

comment Practical difference between SPARC vs x86
The only time I've seen sparc in the wild is in legacy systems that are on Solaris and cost too much to move to any other platform. That's also why they're so expensive - smaller market share means less demand which means a higher price.

comment SuperMicro CSE-815TQ-560B server is LOUD…can it be quieted?
The problem with 1U servers is that they need to move the same amount of heat as a 2U server, but the fans are 1/4 the size, so you need a) more of them to be at b) a higher RPM. A am surprised by your 1U server only having 4 fans - normally they'res about 6 or 8 of them. Both of these increase the volume of noise dramatically. You'll find a 2U server is much quieter, and almost bearable.

comment Stuck with Cisco DHCP pool issue
If 192.168.1.1 is a router that gets you out to the internet, then yes. I've only seen routing to an interface like you have there when it's a PPP connection, but my experience with different types of interfaces on iOS is limited.
