I have following questions:
1) Can I run single CPU first? Add another CPU later when in need.
2) There are 2 sets of dimm. Each set serves its own CPU, I suppose. If running single CPU can the RAM on the 2nd set of dimm be detected and used?
3) What will be the comment on xeon vs amd, same spec (apple to apple)?

View 4 Replies View RelatedI am running some muti-threaded code that uses a lot of memory (~6GB). I have it compiled on a cluster that uses Xeon 5160 quad core CPUs with 4MB cache/core, 8GB of RAM and kernel 2.6.18 (x86_64) and I have also the same code compiled on another cluster that uses Opteron 2214 quad core CPUs with 1MB cache/core, 8GB of RAM and kernel 2.6.28 (x86_64). On the Intel cluster the code generates barely any system load when I look on top but on the AMD cluster it can generate over 50% of system load. On the intel machines my process can generate a constant load of 3, while the load generated by the process on the AMD machines is about 1.6.
Does anybody know what could cause this? Could it be the version of the kernel or the difference between the CPUs (for example, the much smaller cache of the AMD CPUS)? My software and all its dependencies are the same on both clusters. I am also using the exact same version of GCC to compile everything.
I am downloading the 64-bit image of Ubuntu 9.10 right now, but I notice the filename has "amd64" in it. Will it only work on 64-bit AMD processors? I want to install it onto an enterprise-class server with a 64-bit Intel Xeon processor.
View 4 Replies View RelatedI'm very new to Linux and I'm looking for some guidance on which version of Linux server I should install. I read several posts that try to compare Slackware, Debian server, and Ubuntu but the message I got is that each version has its pros/cons. The version that you end up using should ultimately be the best for what you are trying to do.
I purchased a HP Proliant DL580 G3 with the following configuration:
(4) Intel Xeon 3.0Ghz CPU's W/ 8mb Cache/667mHz FSB
16GB RAM @ 16 x 1GB ELPIDA PC2-3200-333
(2) 36.4GB 15k U320 SCSI Hard Drives
(2) Power Supplies
DVD Drive
This server will be configured as my web server and database server. I will use Apache and MySQL.
I want the server to be as secure as possible and will be following the recommendations on the book "Hacking Linux Exposed" to configure Linux.
I would like to install a version of Linux that will utilize all of the server's resources - the 4 x Xeon Processors and the 16 GB of RAM. As for the RAID configuration I plan to just have the hard drives mirrored. And lastly someone recommended that I cache my website in the RAM for faster load times. I have not researched this yet but would like the Linux version suggested to allow me to do this. I assume any Linux version would allow me to do this but I thought it would be safer to include it in this list.
I've got a dual Xeon 5570 (Nehalem) server. It clocks down properly, but never, under any circumstances that I've found, clocks up past its TSC. Even when running basically nothing but cat /dev/zero > /dev/null, nothing gets clocked higher than the TSC. Below is the turbostat output, which clearly knows what the hardware is actually capable of, but it never actually achieves it. I'm running Lenny, with backported kernel 2.6.30-bpo.2-amd64. I tried the 2.6.32 backport and there wasn't any difference. know where I should look next? BIOS settings? Do I need to change some kernel option and recompile?
# ./turbostat
Nehalem multiplier 22, TSC frequency 2933 MHz
Nehalem 4 cores active: 24 mult, max turbo frequency = 3200 MHz
Nehalem 3 cores active: 24 mult, max turbo frequency = 3200 MHz
Nehalem 2 cores active: 25 mult, max turbo frequency = 3333 MHz
Nehalem 1 core active: 25 mult, max turbo frequency = 3333 MHz

Currently our cluster is based on AMD opteron processors. We are going to add more nodes however I want to know is it good to add Intel xeon processors. They both claim to be x86 compatible however I don't know if they are really math each other.Does a program compiled on Intel xeon really works on opteron (amd64)?
View 11 Replies View RelatedMy work reponsibilities now include a new server running Centos 5.2 on a Dual Xeon Dell server machine with Raid 1 on 2 160Gb disks, but I have no experience of Linux, let alone Centos.I figured I'd download an image and load it on a spare machine just so I could get used to the OS and try things out without risking my live server. My only available spare at present is a Toshiba laptop from 2000 (it was top of the range at the time, but probably looks bad compared to my pocket smartphone now).My questions are:
a) Is it feasible to load Centos on this old donkey of a laptop? Would I struggle to find the right drivers, etc., or is it all contained in the distribution?
b) Assuming it runs, would the differences between the two implementations significantly affect my learning experience?
c) Assuming the two are similar enough to make the laptop a useful reference/staging/learning tool, where do I start? I've already downloaded an ISO image for LiveCD (i386) and burned it to a CD but the CD doesn't seem to have anything I recognise. Windows (both Vista and XP) treats it like any data CD and shows no autorun behaviour with it.
System recognizes that CPU is capable of throttling, but there is no module to govern it. So Xeon always runs at full frequency.This is not convenient as my server is not always in full use, so I would like it to lower power consumption, especially for AC, with frequency scaling enabled.Can you help me is this some bug, misconfiguration in default kernel or guys who writes kernel think that scaling is not necessary for servers processors?
From my analysis so far, I think that the issue lies with the fact that module acpi-cpufreq does not support Xeons and that there is no dedicated module for this processor family (e.g. p4-clockmod) module in the default kernel.
I just installed a new HP DL360 with 32 GB of RAM and a Intel Xeon X5550 which supports speed stepping and turbo mode. I've enabled turbo in the BIOS, but cannot seem to get CentOS 5.4 to make use of either of these features. I've been googling for a solution for a while now, and tried various things, such as installing cpufreq. However, when I type cpufreq-info, I get this:
# cpufreq-info

I would like to run my own server, and I'm thinking of buying a dedicated machine to run it on. I checked out the dell website for a cheap machine to run it on (I don't need high performance - just a personal file server running a few hard drives, and a web/mail server). I noticed that they have some cheap models in their server line that are as cheap as a desktop. Compare:
[URL]
The main difference I see between the desktops and the servers is the use of the Core or Xeon processor, and also, the servers tend to have lower RAM.if I am looking for value, should I opt for a low end desktop or a low end server to run a personal server? Also, what advantage does the Xeon processors and Dell server line have over the desktop models that make it better for running a server?
i found this video, and i really want to do the same. *newbie needs to learn [URL]...my question is, what need to be installed and how?
is there any specific configuration to make it works?
and will it work if i want to connect from Ubuntu to Fedora ?
I'm curious if anybody can shed some light for me in this department. We're in a large environment with a Windows DHCP Server. We have been tinkering with LTSP on Edubuntu as thin and fat clients. It works great, but right now we just have 1 server handling the lab, which works fine unless we want to expand, which may be very possible.
These are the instructions I received:
Login to your windows server and load the DHCP configuration screen
Create a DHCP reservation for the MAC address you obtained
Add the configuration options below to enable the machine to boot from the LTSP server
017 Root Path: /opt/ltsp/i386
066 Boot Server Host Name: <ip address>
067 Bootfile Name: ltsp/arch/pxelinux.0 # Specify CPU architecture in place of 'arch', for instance 'i386'

I'm curious, what if I want to have multiple Ubuntu servers on the network that I want to have bootable? For example, let's say I have 3 labs, and 3 servers. Server A to Lab A, Server B to Lab B, and Server C to Lab C. I want all C's computers to boot to C, and B to B, A to A, etc.
1 - How would I add multiple entries on the Windows DHCP Server to allow all 3 (A B C) servers to boot?
2 - How would I be able to isolate the clients so ONLY Lab A clients boot to Server A, etc?
I am looking for a version of vmware that manages 2 severs at the same time and that mirrors them such that if one goes down we can still work on the second and of course it also works as a backup. Also, must work on a ubuntu server I have looked but there are so many version that I don't know which one is the best.
View 1 Replies View Related(Mods: If you feel this belongs more in the Games or Wine discussion area, please feel free to move. This question does intersect many areas, so was unsure where to put)
I have a funky server Ubuntu 9.10 Enterprise setup where I have X on all the time (using Xfce4 - not Xbuntu) with latest wine so I can run Windows only based game server executables. One of the applications is a simple dedicated racing game server made by the company I work for that works perfect in wine (unfortunately, the full 3D game client does not, so its a windows only game). The other is more just to test, runs Serious Sam HD dedicated with wine with a steam client active in background since SSHD Ded requires a steam client logged in (just create a dummy account).
Im getting some lag issues with the SSHD on the end-users client side. Unsure if its related to it being a more complex game and using wine to translate slowing it down. Things like tiny warps once in awhile, and the ping of clients kinda jumping around.
Im pretty sure my network settings are ok. Maybe not fully optimized for every bit via ipv4. Still though. This 1U Opteron server is in a ISP with a full 1000 up and down. Ports are locked out that aren't being used. I do have apache going, but its nothing strenuous. The CPU isnt used overly so. Maybe peaks out around 60% under strain, but mostly 20-40%. Memory use is about 550-700megs for SSHD itself. Given, it only has 2 gigs total at this time, but I still usually have near a Gig of memory available at most times.
I admit newbness of linux servers in general. Was reading about other game servers like CS:S requiring a ticked kernel near 1000 to get the least amount of lag. Some even saying they dropped the tickless options of the newer 2.6 kernels on purpose because they produced lag. Was checking on the history of newer Windows Server like 2008 and they still use a ticked OS, though a more optimized version.
So this boils down to should I be running a Ticked OS kernel to run a more complex Windows based dedicated server? I haven't tried thus far, well because I am again a bit of a n00b to all this. That and I'm not sure you have to tell wine or the SS:HD dedicated exe itself to run at a full ticked rate (no option I have seen for a command line function in the SS:HD itself).
I have Webmin installed on an Ubuntu server. I currently have a successful apache server running on port 80, however I want to create a virtual host on port 81.

How ever when I goto 192.168.1.5:81 (local ip, I know I have to port forward but its not even working local) it does not work.

I'm going to make an internal domain and will probably be running the following: Kerberos, Samba, Apache, Postfix, mysql, bind, dhcp, SVN, GCC, and Nagios. So in summary, I'll have the following roles; domain controller, web server, file server, and network monitoring services. how they would handle splitting these services up between two servers?

I currently have a group of 3 servers connected to a local network. One is a web server, one is a mysql server, the other used for a specific function on my site (calculation of soccer matches!).
Anyway, I have been working on the site a lot lately but it is tedious connecting my USB hard drive to each computer and copying the files. This means I am not backing up as often as I should...
I have a laptop connected to this same network that I use for development so I can SSH into to the computers, is there any software for ubuntu that can take backups of files that I choose on multiple computers? I know I could rsync but is there something with more or an GUI?
Then I can just every 2 days move the most recent backup from my laptop to the USB drive. Then I will have the backup stored in 2 places if things go kaboom somewhere.
I'm running Ubuntu Server 10.04 and have a secure (SSL/TLS) FTP server on it. However, I'd like to use this FTP server to update programs I made using Microsoft Visual Studio. Unfortunately, in Microsoft's infinite wisdom, secure FTP servers cannot be used. Rather than use an insecure FTP server, I want to set up my secure FTP server to be able to access whatever I need to on the machine, and then add an insecure FTP server that only has access to the directory where I put my update files. I am currently using vsftpd as my FTP server. Is there any way that I can set up two FTP servers on this single machine?

Or, sometimes, I just need to create the same 10 users on x number of machines, and it's tedious to do this 10x times. Plus, then, if you need to change a password or delete a user, you have to do it x times.Any recommendations on how to centralize users/auth?
