Cluster poweredge servers
Hi everyone,
I just started "working" as a cluster admin. It is not really a job, it is more like: "hey you, try to use this for your programs".
I have been searching for some documentation but there is not a "big book" to solve the issue, si I've decided to give this forum a try and learn some usefull stuff about cluster-managment-other topics.
In a few words:
I have 3 nodes (PowerEdge R320, R820, R7425).
1 Switch Model N4032.
1 fiber connected (NAS?) HD's Model 1400
I want to make a clúster runs starting with this from scratch.
I want to use R320 as login acces (maybe with virtual machine), but first of all, I would like this node to "start", I installed Centos7 but it stop at certain boot point waitting for a "IP"
CLIENT MAC ADDR: XXXXXXXX
DHCP....*
I've read about configuring iDrac but I do not understand how to acces via web navigator because I cannot run the OS.
In the end, I DO NOT want a main solution but if someone can wrote a guide like:
1- Configure switch that allows ....
(search more info in www.here.com)
2- Install OS in login node, configure .....
(look here --> www.help.com)
3- configure iDrac to manage remotely the cluster ....
It would be apreciate. I will continue searching for some info. Thanks a lot !

The iDRAC isn't going to be cluster aware, it's just going to manage the associated server it's part of. I just wanted to make sure that you didn't have a different expectation on that end.
I found a fairly detailed article on setting up an HA cluster in Cent, it may be of use to you. https://dell.to/37zdHxt
I found another article here: https://dell.to/30YihCP
That should have a fair amount of information regarding clustering in Linux. I would also add that with clusters, we generally recommend having hardware platforms as uniform as possible, but the servers you're working with are going to be very different, so it may be worth noting, depending on what the role of the cluster ends up being.
