How to identify the make and model of disk and memory on a Linux server

Question

Given a linux server (in my case Ubuntu) what's the easiest way to find out what make/model of harddisk and memory are being used?

i.e. what is the equivalent of /proc/cpuinfo for disk and memory?

Thanks. J

Answer 1

You can get a lot of information about your system like this:

sudo lshw | less

To limit it to particular types of devices:

sudo lshw -class CLASS

Where "CLASS" might be "disk", "storage", "volume", "memory", etc. To see what classes are in use, do sudo lshw -short.

You can use this to show the vendor, model, serial number, size, etc. of your hard drives. I don't know of any way to show vendor and model of memory.

Answer 2

I think a more simple approach is to use the hdparm command, by typing hdparm -i /dev/sda for example.
