Quieting down HP Proliant DL380 G5 server for home use

[mikeymikec]

I have a sneaking suspicion that this server also has software-based fan management (and without it the fans go full tilt non-stop), which should in theory make the job of adaptation easier, but since this is HP/Compaq, no.

A. CPUBoss is wrong. As stated in my previous post, the 975 is a 130W TDP (http://ark.intel.com/products/37153/Intel-Core-i7-975-Processor-Extreme-Edition-8M-Cache-3_33-GHz-6_40-GTs-Intel-QPI?q=i7 975). I don't know where the hell CPU boss is coming up with 212W. Certainly not at stock clocks. The cache is also wrong, the 975 is a 8MB cache and faster. The X5400's don't have hyperthreading or turbo. Comparing (on CPUBoss) the X5470 to the X5460 (same processor, 200mhz slower clock), they state the X5470 is 50% faster on the Geekbench test. Bullshit. So, I wouldn't trust their numbers. Stating "Windows Server 2008 takes advantage of all 8 cores" would seem to indicate to me that you're not aware of how multithreading works. Tossing more threads at Windows doesn't magically make it faster.

B. 303W is a LOT. For comparison, my DL380G6's with 2x L5640's (6C/12T) and 128Gb of RAM pulls 170W under my normal operating load (half dozen VM's).

C. I'll give you the price because I don't recall what I paid back then. $150 is normal these days.



You're on crack. The G6 and G7's are almost identical, the G5 and G6's aren't remotely close. They "share the same driver" to the extent Intel's driver package covers pretty much every chipset they've made in the last 15 years.

G5: Intel 5000 chipset, LGA771 Woorcrest-Harpertown processors (4C/4T Max), FB-DDR2 RAM.
G6: Intel 5520 chipset, LGA1366 Nehalem EP-Westmere EP processors (6C/12T Max), DDR3 RAM.



IF you've set them to balanced in the BIOS, then yes they will be balanced. Given the age of these systems, I'll give you that you MAY be better off running both. On newer systems, that's less likely. Power supplies are generally at peak efficiency around 80-90% load. Running two power supplies at 40% load is likely using more power than one power supply at 80% load. Dynamic Power Regulation is purely controlling the C states of the processors and is not at all effected by power supply count.

Wow the G6 has a newer intel chipset big woops the cpu's are not that much better in reality, the smart array and sas disks along with the accelerator are exactly the same. as is the ilo, the fact that it uses ddr3 ram does not offer much of a performance difference either, and the performance it does offer is unlikely to be noticed by a home user or a small business anyway, unless you are gonna run a skype for business sever or something that is really resource heavy you are unlikely to notice the benefit.

and i think it is you that is on crack @XavierMace

HPE's Own Power Advisory Calculates the consumption of the G6 to be with in the margin i suggested at 50% utilization so what ever you are running is clearly hardly touching your server, to get 170w, so stop talking bollox when even the manufacture shows your usage figure is unrealistic in a real world scenario with realistic utilization, how many users does your system have connecting to it just you lol or a couple of people stat putting a real work load on your server before you start quoting usage which is not likely for most users. Seriously, Here is the calculation from hp you idiot

Wow, aren't you special. For working with them since you were 12, you sure don't know much about them. Or I guess maybe that was just last year.

A. If you don't see the advantage of the 6C/12T processors you can get in the G6's vs the 4C/4T processors you max out with the G5's, you're just too dumb to talk to.
B. The P400 on the G5 is a SAS 3Gb/s controller, the P410 on the G6 is a SAS 6Gb/s controller. You have a most interesting definition of identical.

I guess that's why I get paid to tell people what to buy.

 

[Chris Wager]

You have overlooked the fact that the p410 smart array became avaliable ad an upgrade for the g5 when the system firmware was upgraded to take a maximum of 64GB of ram. And the last g5's sold could actually be brought with a p410 smart array. All of mine have the p410 install so that is not a relevant issue and I can see the advantage if you are using it in a commercial involvement with a need for the preformance that offers I would not recommend g5's for production. Use in a business world at all. And in fact I don't and FYI I also tell people what to but for business and enterprise. But the issue we were discussing here was the g5 as a home server which it is more than adequately suited to do and for home use it don't think most users would suffer a noticeable difference between the g5 and g6 unless that have a serious work load to carry out like constant video conversions etc.

so much fail in this thread, xavier it seems you are wasting your time with these replies.

The performance / power of Nehalem / Westmere is already considered bad by today's standards (and I say that as someone running dual HP Z800s with 4x X5690s).

Performance / power of Core2-based Xeons are just downright atrocious.

Welcome to the world of rackmount servers. The louder it is, the more powerful and/or important it is. You now need a 42U rack in a separate enclosed room. Noise is no object. Fire that baby up as is! 😛
