comment DNS not working with Ipv6
Nslookup uses it's own libraries, dig uses the default resolver - you should be good unless you need nslookup to be able to look it up for whatever reason. Nslookup is an old tool, and while it isn't officially deprecated, most people prefer dig when available. If you are using nslookup in a script or something for monitoring, consider using dig instead.

comment Setting up Infiniband network - wrong route
ipoib requires standard arp - you should see ipoib entries in the arp table that will have the GUID and IP of the ib devices on the same network.

comment Setting up Infiniband network - wrong route
192.168.2.107 and 192.168.2.108 are on the same network - you shouldn't need a route to talk. Are they arping properly?

comment Storage Network Stops Transmitting Traffic
The chelsio t320 driver has an issue where it suspends the card instead of reinitializing when it hits a fatal error. The root cause is really a hardware failure. Can you see any errors in logs (fatal errors/parity errors) relating to the cxgb interface?

comment QoS Degrading VOIP
The biggest problem with VoIP is that you can't control the whole path. QoS only goes as far as your router and then the packets do as they will along the rest of the journey to their intended destination. I did a pretty thorough write-up on SU: superuser.com/questions/80580/how-to-improve-voip-sound-quality/…

comment Proper way to create an NS record in Windows DNS
As a point of being practical, I agree with you. If it works, it works. However, you don't really answer the question. If it doesn't matter, why? what exactly does Windows Server do internally to create that link? If you see my update, it appears to generate and return an A record, even if it doesn't show up in the A record list in the management console. What I'm unclear about is if that sort of "shortcut" would pose an issue under any circumstances, or if it is perfectly valid and OK to do.

comment Measuring network performance
What sort of control would you have over the servers? There are several options such as iperf (which is what speedtest.net uses) and SNMP. There are also better methods of using ping to look for not only latency, but jitter as well.

comment Scalable NAS: on-premise and minimum of 6 TB
glusterfs is a good cheap way to set up a scalable distributed file system. There is no support and it will take some effort to build it all initially, but would do what you need.

comment Options for SATA ports on motherboard for Files server
Much of the solution also isn't just in how you build it, but how you utilize it as well. There are a lot of storage solutions capable of managing 300TB, but depending on how you'll access it, type of reads/writes, amount of clients connecting, size of files, etc, the solution you want will vary greatly.

comment Transfer between two NFS shares on the same machine
why not take a pcap or use netstat to look at traffic/connections to see what, if anything, is going out over the wire? Or use strace to see what calls are being made with the mv?

comment How to achieve multiple NFS/TCP connections to the same server?
see section 5.6 tldp.org/HOWTO/NFS-HOWTO/performance.html - it talks about increasing the number of nfsd instances.

comment How to achieve multiple NFS/TCP connections to the same server?
Multiple connections is going to be the only way to do what you're looking for. A single stream should max out around 350MB/s per thread on a fine-tuned nfs server. In any case, if we don't know what distro or nfs version you're using, it is hard to give a good recommendation.
