Nic Teaming recomendations with iSCSI, VM and LAN
Hi all
I have a two servers (DELL PowerEdge R710) that both have four NIC's. I allso have two PowerConnect 5424 and one Dell PowerVault m3000, wich allso have 4 iSCSI connections and two LAN connections. I nead some recomendations on how to set this
up. I have found lots of info on how to do the cabeling and I ended up with this scenario:
Server(s) connects to the switches using two cable (total of four)
PowerWault connects the the same switches the same way, a total of four cables.
The switches are allso connected using one cable
I think this wil give redundancy.
So what next? I have installed the software that I can use to team the nick, but I have the impression that I nead tree separate LANS here, one for iSCSI, one for VM-Nett and one for the clients. I have therfore come to the conclusion that I
have to connect like this:
[HOST1]
nic1:-------SWITCH1
nic2:-------SWITCH2
nic3:-------LAN Switch
[HOST2]
nic1:------SWITCH1
nic2:------SWITCH2
nic3:------LAN Switch
[DISK ARRAY]
Controller 1:
iSCSI0:----SWITCH1
iSCSI1:----SWITCH2
lan:--------LAN Switch
Controller 2:
iSCSI0:----SWITCH1
iSCSI1:----SWTICH2
lan:--------LAN Switch
What I dont understand here is what the LAN connections on the disk array is for, except of course, if the LAN clients are to be able to connect directly to them. I kind of wanted this to happend through one of the VM's that will be running.
What I would like to know is if you recomend using NIC teaming. And if so, what of the nett would be teamed? Its not possible to team all of them s9ince its onløy four nics pr. host. So I basically can team either the iSCSI nett,
VM-nett or the LAN nett. The Lannett I would not expect to be teamed, but what about the iSCSI and VM-nett ?
Thanx in advanced..
