need help to identify if server disk is hdd or nvme (solved)

donko

Hello, i'm helping a friend who someone sold him a "dedicated server" from ovh.

So while checking i realize the server is actually a virtualized LXC container.

Icon name: computer-container
Chassis: container
Machine ID: zzzzzzzzzzzzzzz
Boot ID: zzzzzzzzzzzzzzzzzzz
Virtualization: lxc
Operating System: CentOS Linux 8
CPE OS Name: cpe:/o:centos:centos:8
Kernel: Linux 3.10.0-1160.6.1.el7.x86_64
Architecture: x86-64

From processor model (E-2274G) i can say is this server https://www.ovhcloud.com/es/bare-metal/infra/infra-1/

The thing is: the server have a 4TB disk but i want to know if is a NVMe disk (maybe is ok the cost he paid) or is the HDD one maybe on raid 0? because seems to have good speeds.

[root@xxxxxx]# df -h

The purpose of virtualize is for better management/provisioning and billing.

From disk performance is similar to RAID 0 SSD or RAID 1 NVME

To save anybody who, like me, didn't know, from having to look it up, this seems to be the output of hostnamectl
