burgemaster Posted January 11, 2012 Posted January 11, 2012 Hi all, Just having a tidy up behind our server rack and have a question that I have always wondered about... Our DC`s among other servers have 2 network sockets. Originally they were both connected up to the main switch with 1gbit connections... They "were" assigned different IP addresses but if I remember there was always a warning about conflicting IPs and we ended up just running one 1gbit connection to each server. Our mail server if i remember has 5 NICs !!!! ? At one point I teamed them all up but then went back to just one... What is correct practise here please? What do you guys do? Thanks in advance
ChrisH Posted January 11, 2012 Posted January 11, 2012 I would usually team them or they have to be on different subnets. Watch your DNS registration as you may not want all of them to have a DNS entry, depending on your routing etc it could mess things up.
burgemaster Posted January 11, 2012 Author Posted January 11, 2012 Thanks for replies, So apart from redundancy on NIC failure, there are no performance benefits to having each NIC connected?? Cheers
jamesreedersmith Posted January 11, 2012 Posted January 11, 2012 If you team them (and your switch supports it) you will get greater throughput.
mthomas08 Posted January 11, 2012 Posted January 11, 2012 Just adding that usually a server will rarely reach capacity even in the peak times on the Networking. I do not think I have ever seen one of our servers struggle on that level. I have occasionally though had to switch from one port to another on our older servers due to one port failing. Not on our newest ones though. Also useful as a Bridge, we have one server with a NIC dedicated through a VLAN for an outside link through our service provider (bit complicated). That NIC is unreachable from internally, only the server it self can access it. Usually it's HD's/Memories and rarely processors.
Mcshammer_dj Posted January 11, 2012 Posted January 11, 2012 teamed and set to seprate switches to allow for increased levels of redunancy. this is linked with 2 power supplies per server and our computer room having 2 seperate ring mains. This means that even if an entire ring fails our servers will stay working
