Concerened about the health of my drives in VMware

I am somewhat new to VMware coming from a Windows background.  I was tasked to start coming up to speed on our virtual server.  As I was looking through the interface I stopped at the health section and started looking at the storage.  I have attached screenshots that show what I think is drive 0.  At first glance this is a bit troubling, but not really sure if I should be alarmed.  The physical machine is a Dell Poweredge R720XD.  When I look at the actual server, it looks like there are 5 drives.  I am not sure how to look at the array to see how it is configured or the actual health of the drives.

Is there another way to view the health/configuration of the storage?

You can use the OEM version of ESXi by Dell, and use Openmanage to check the RAID configuration.

you can also look at the Hardware Status (via vCenter Server) or Hardware Status directly connected to ESXi.

see my EE Article

HOW TO: Use Dell OpenManage Server Administrator to Create and Manage a Virtual Disk (RAID Array) on a Dell PowerEdge Server with VMware vSphere 5.0, ESXi 5.0 installed.

You could put the host in maintenance mode and shut it down and while booting go into the usually ctrl x, ctrl a, or ctrl  something to get into the controller card.  In there you can view the drives and health and information.    

Or you can use open Manage

This is a production system and very difficult to take into maintenance mode.  I was told by a former employee that the Open Management software is installed on the server but it is not a DELL OEM version of esxi.  If it was indeed installed would it show in the tabs across the top of the vsphere client?

No, you need to access it, as per my EE Article, but if it's not the DELL OEM edition, I'm not quite sure how Open Manage would work!

You can check for definite if you are using the OEM edition, because it will state in the Summary Profile.

it does look like it is the DELL Version
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
Yep, that is the Dell OEM version.

Your ESXi 5.5 needs patching it's about 2 years old! Latest patch was i Oct 2015!

Enter hostname and username/password into Open Manage, and logon.

I am able to open Dell OpenManage on my desktop, but when I try to access the esxi server I receive the attached error.  I still am not sure if OpenManage is installed on the server and wonder if this is causing the error.  I am using the same credentials that I use with vsphere.  Again my colleague said that he had OpenManage installed before he left, but I am not sure.

also could the login error be because it needs patching that you suggest?
Andrew Hancock (VMware vExpert / EE MVE^2)VMware and Virtualization ConsultantCommented:
if you have the correct IP Address or Hostname, username and password, you should be able to login to OpenManage, otherwise it's not installed.

also could the login error be because it needs patching that you suggest?

very unlikely.

Thanks for your help Andrew.  

In your article you mentioned the following:
Dell OpenManage System Administrator for ESXi 5.0 must be installed on the ESXi 5.0 host to be managed.

Will this also work for my ESXi 5.5 installation?
