Proxmox 4.4 question regarding SSD storage

[Mecanik]

I have a question, and if it's a dumb one please don't judge me because I am fairly new to Proxmox and starting to get accommodated...

I have a dedicated server with 2 x SSD drives with Soft Raid, but I am able to use only one in Proxmox, and that doesn't seem right to me.

I don't quite understand Soft Raid, should it be like this ? Because I have other dedicated servers with Hard Raid ( 2 x 3 TB for example ) but in Proxmox -> Datacenter -> <node> -> Disks I can see only 1 disk, while on this dedicated server with 2 x SSD's I can see both disks:

So I guess the overall question would be, can I use both disks ? If so, how do I mount the second one ?

I really hope I can use the second disk as well, because with just one I can't really create many VM's.

Thank you

first, software raid is not supported by us, if you want to buy a subscription with ticket support in the future.
second, software raid is, as the name suggests, done in software so the os sees both disks, but generates a virtual one (usually /dev/mdX) on which it operates

you can verify you use both disks by looking at the output of lsblk
there it should show 2 disks as part of a raid for the root partition/lvm/whatever it is configured for

Thank you, the output of lsblk is:

This means it's using both disks ? Because after I created 2 small VM's I see only 100 GB left as "space" ...

yes it uses /dev/sda1 and /dev/sdb1 as / (md1) and /dev/sda5 and /dev/sdb5 as /var/lib/vz (md5)
