Dual Hexacore Opterons w/ 96GB RAM (Minecraft Servers)

post #1 of 14
Thread Starter 
I am putting together a new server build for running a LOT of Minecraft servers, and am considering moving over to AMD. How does this build look? I want to make sure I am not missing anything...

2x AMD Opteron 4180 Lisbon 2.6GHz (12 Physical Cores)
http://www.newegg.com/Product/Product.aspx?Item=N82E16819105275

TYAN Dual Socket C32 Motherboard
http://www.newegg.com/Product/Product.aspx?Item=N82E16813151224

12x Kingston 8GB DDR3 ECC Registered Memory (96GB RAM)
http://www.newegg.com/Product/Product.aspx?Item=N82E16820139280

2x Western Digital RE4 500GB Hard-Drives
http://www.newegg.com/Product/Product.aspx?Item=N82E16822136697

1U Supermicro Chassis (already have this)
http://www.newegg.com/Product/Product.aspx?Item=N82E16811152085

My main concern is the RAM. I can't understand why these 8GB Sticks are so much cheaper. If you buy any 8GB DDR3 ECC Registered as a 24GB bundle (3x8GB) its around 400$, where as these are about 250$ for the same thing.

Also, are the CPUs worth it, or should I hold out for the Bulldozer processors?

Honestly you will be fine with those specs. I think 96GB is overkill for minecraft though.

Edit: Lmao, hey Brett.

From what I've noticed, Minecraft seems to be much more bandwidth dependent than anything else.

How many servers/people per server are you expecting with a system like that?

He manages a game server provider, so I don't think that will be an issue.

From what I hear from several providers, Minecraft murders disk I/O, so I'd look into that.

@techmaggot - That is actually the reason for so much additional memory. I have been developing some software for our Company's Minecraft servers that use a RAMDisk generated on the fly (for the World folder) as opposed to off the Hard-Drive.

@Limes - Is that you George? haha

Brett!

How is good o XFactor doing?

EDIT: Build looks good. I wonder how much more performance you're going to be getting for that extra amount of ram setup as RAMDisks, though? Especially in Minecraft

Alex.

Use SSDs, more space, no noticeable speed differences.

Nice. I was going to recommend looking into that but I decided not to because I don't know of a way to do routine backups or anything, so people won't lose their worlds if the machine loses power for some reason.

@techmaggot - Well I actually used an .NET API to implement a fairly efficient RAMDisk Driver, so that opened me up to control the rest of it from my application as well. I am using VSS (Volume Shadow Copy) to do frequent backups of the world from the RAMDisk to a physical location. My main concern is the server possibly going down mid-copy, and corrupting the data, so I will probably do something like a backup to .iso every 24 hours as well or something.

@Limes - Ah hey man. Never would have associated that username with you tongue.gif

@Balsagna - Hi! People I know are coming out of the woodwork lol. Who are you?
