How To Find Out Maximum Supported RAM In Linux.How To Find Hardware Specifications On Linux.Product: Inspiron N5050 (To be filled by O.E.M.)Ĭapabilities: smbios-2.6 dmi-2.6 smp vsyscall32Ĭonfiguration: boot=normal chassis=portable sku=To be filled by O.E.M.
In Debian, Ubuntu, Linux Mint: $ sudo apt-get install lshwĪfter installing lshw, run the following command to find out if your system is either physical or virtual: $ sudo lshw -class system In RHEL and derivatives such as CentOS, scientific Linux: $ sudo yum install epel-release $ sudo yum install lshw In Arch Linux and derivatives: $ sudo pacman -S lshw If it is not installed already, you can install it as shown below. Some Linux distributions comes pre-installed with lshw. It displays all hardware details including memory configuration, firmware version, mainboard configuration, CPU version and speed, cache configuration, bus speed, etc. The lshw utility is a small command line utility that displays the detailed hardware information of a Unix-like system. If it is virtual machine, you will see output something like below. If it is physical machine, the output will be: physical Virtual => physical Īlternatively, use the following command: $ facter virtual If this command doesn't work, try with sudo privileges: $ sudo facter 2> /dev/null | grep virtual Once facter installed, run the following command to check if the system is physical or virtual machine: $ facter 2> /dev/null | grep virtual In openSUSE: $ sudo zypper install facter In CentOS, RHEL: $ sudo yum install epel-release $ sudo yum installl facter
In Arch Linux, Manjaro Linux: $ sudo pacman -S facter You may need to install it as shown below depending upon the Linux distribution you use. Unlike Dmidecode, Facter doesn't comes pre-installed by default. Vendor: EFI Development Kit II / OVMF Method 2 - Using Facter utilityįacter is a command line utility to collect and display a system's information.
Manufacturer: QEMUĪnd, one more dmidecode command is to achieve the same goal: $ sudo dmidecode | egrep -i 'vendor' Yet another dmidecode command to find the remote system's type is: $ sudo dmidecode | egrep -i 'manufacturer|product'
Product Name: Standard PC (Q35 + ICH9, 2009)Īnother command to find out if it is a physical or virtual system is: $ sudo dmidecode -s system-product-name If it is a virtual system, then it will show the virtualization software/technology (i.e VirtualBox or QEMU).Īlso, you can use this command to check if it is physical or virtual system. If it is virtual system created with KVM/QEMU, the output will be: QEMUĪs you see in the above output, if it is a physical system, dmidecode will show the manufacturer's name (i.e Dell Inc.).
If it is virtual system created with Virtualbox, you will get the following output: innotek GmbHįor those wondering, innotek is a German-based software company that develops PC virtualization software called VirtualBox. If it is a physical system, you will get an output something like below. $ sudo apt-get install dmidecodeĪfter installing Dmidecode, run the following command to find out whether your system is a physical or virtual machine: $ sudo dmidecode -s system-manufacturer Say for example, the following command will install dmidecode in DEB based systems such as Ubuntu, Linux Mint. Just in case, if it is not installed already, you can install it using your distribution's package manager.
Dmidecode, DMI table decoder, is used to find your system's hardware components, as well as other useful information such as serial numbers and BIOS revision.ĭmidecode comes pre-installed with most Linux distributions. For 200, you need to double the size, for 500, you take it times five.The easiest way to find if we are working on a virtual or physical machine is using dmidecode utility. To answer your question - 100 IOPS (write) should be doable with a 67GB zonal standard PD disk. If you want more, go for SSD disks or increase the disk's size. So, if you have a 100GB disk, you can expect 75 IOPS (read). Reading you can find (as of ) that if you choose a zonal standard PD, you can expect 0.75 IOPS per GB for read. Up to a certain threshold which will be determined by the VM type (a slow CPU can't deliver more than so much IOPS). The bigger the size, the higher the IOPS will be as requests can be parallelized. You can determine your VM's IOPS performance by choosing (a) the type of persistent disk and (b) its size.
