Adding extra processor post-installation versus installing on two – 2008 R2

I have a Windows Server 2003 installation which is getting pretty long in the tooth, so I have decided to install Windows Server 2008 R2 Standard instead. I have verified that the server is capable of running the OS, and everything is set. At the same time, I’m considering installing an extra processor, but the delivery takes a few days. And now for the question: Is there a difference in the potential performance of an […]

cat /proc/cpuinfo shows 3.00GHz model but 1400.000 cpu MHz?

I ran this command on ssh to see CPU info: cat /proc/cpuinfo And it says: … vendor_id : GenuineIntel cpu family : 15 model : 4 model name : Intel(R) Pentium(R) 4 CPU 3.00GHz stepping : 3 cpu MHz : 1400.000 cache size : 2048 KB … Why is cpu Mhz 1400 ? Wasn’t it supposed to say 3000Mhz ? OS is CentOS 6.0 the 1400 means that at which speed the processor is running […]

Are Intel Core i3/i5/i7 Processors Server-Grade?

Many web hosting companies are now offering Intel Core i3/i5/i7 processors under “cheap dedicated hosting.” But my laptop has an Intel core i3 processor, which makes it more likely a desktop processor than a server processor. When I spoke to one of the web hosting company’s tech support official about this, he told me that their “i3 processor comes bundled with ECC/Registered DDR3 RAM on a server-class motherboard (socket LGA1156).” Furthermore he told me this: […]

HP DL360 G5 Processor Upgrade

I’ve recently acquired a DL360 G5 with Xeon 5410’s in it (quad core, 2.3Ghz). We’ve also purchased some Xeon X5482’s – which I understand are near the top of that same processor range. I’d like to upgrade this G5 with the faster processors, but when I swap out the processors, and turn on the machine, it simply sits there in “high fan” power on mode, and never comes out. Is some sort of BIOS upgrade […]

Two Dual Core vs. One Quad Core

For an Intel based system keeping the number of cores constant how much difference would there be between two dual core processors and one quad core processor? We run Oracle OLTP databases on two dual core processors. With fewer dual core processors available we may need to switch to quad core, but we are limited to four cores due to licensing issues, so will have to switch to one processor. If we make the switch […]

What virtualization software can emulate different architectures?

… like running a PPC or ARM system on x86 hardware. As far as I know: VMWare can’t QEMU can KVM can because it uses QEMU Is this correct? What other solutions are there? That’s not virtualisation, that’s emulation. Virtualisation can be seen as a specific kind of emulation where you emulate the same machine on itself, accelerating the emulation by letting some of the instructions run for real. Your question should just be “What […]

Can a Multi core CPU be configured to allow the OS to the see the cores as a single CPU

Can a Multi core CPU server be configured to allow the OS to see all the cores as a single CPU and there by allowing the processor to function as a single CPU? A lot of modern day servers are multicore CPUs. Are they ways for all the CPU cores to report as 1 CPU to the OS? This would be handy to run applications was designed for a single CPU. What you’re asking is […]

Advantages and disadvantages of ARM vs x-86 processors in future laptops

Recently I’ve started reading about ARM processors coming out on low-cost and low power laptops, such as these unveiled at computex in Taiwan. I’m one of the Tech people at my company, and often I get asked for my opinion when picking out new equipment. In the coming years if these devices become prevalent, what would the advantages and disadvantage of picking one over an x86-based device be? ARM chips are RISC processors that were […]

How do I know from the Linux command line what kind of processor I have?

How can I tell from the Linux command line what kind of processor my machine has? E.g. AMD Opteron or Intel Core 2 Duo. uname -a just tells me it’s x86_64 but that isn’t enough information. dmidecode or preferably cat /proc/cpuinfo dmidecode will give you a lot more info than just what processor, thou /proc/cpuinfo provides more info about the processor itself Check more discussion of this question.
