hp - What RAID configuration do I actually have?

So lately I've been playing around with my recently purchased (used server) (HP ProLiant ML330 G6) and I am a bit confused as to the current RAID configuration it has. I did a bit of checking via the HP System Management webpage on my server and noticed the following, which in turn leads me to believe it is a RAID 10 configuration, as per the Smart Array controller.

To confirm, I have 4 slots with 4 x 1TB drives in there. In the screenshot above it clearly states 1+0.

From what I understand, RAID 10 is a stripe of mirrors as per the image below.

So if the data is distributed and mirrored across all disks(as per the image above), then why do I see 2 x Logical disks in my system with 1TB each? Why don't I just see 2TB total in 1 single logical drive, as per the image above?

EDIT

Additional Drive information as per request..

Answer

In HP-speak, Arrays are the physical grouping of disks. Logical Drives are a subset of the Array and present the actual block device to your OS.

You can have multiple Logical Drives within an array. Those Logical Drives can have different RAID levels as well.

For example, this is a group of 6 disks with two logical drives, each of RAID 1+0 (RAID10):

  array A (SAS, Unused Space: 1857528  MB)

  logicaldrive 1 (72.0 GB, RAID 1+0, OK)
  logicaldrive 2 (1.5 TB, RAID 1+0, OK)


  physicaldrive 1I:2:1 (port 1I:box 2:bay 1, SAS, 900.1 GB, OK)
  physicaldrive 1I:2:2 (port 1I:box 2:bay 2, SAS, 900.1 GB, OK)
  physicaldrive 1I:2:3 (port 1I:box 2:bay 3, SAS, 900.1 GB, OK)
  physicaldrive 1I:2:4 (port 1I:box 2:bay 4, SAS, 900.1 GB, OK)
  physicaldrive 2I:2:5 (port 2I:box 2:bay 5, SAS, 900.1 GB, OK)
  physicaldrive 2I:2:6 (port 2I:box 2:bay 6, SAS, 900.1 GB, OK)

But I could also do something like (note the RAID5 Logical Drive):

  array A (SAS, Unused Space: 2534  MB)

  logicaldrive 1 (72.0 GB, RAID 1+0, OK)
  logicaldrive 2 (1024.0 GB, RAID 1+0, OK)
  logicaldrive 3 (869.1 GB, RAID 5, OK)

  physicaldrive 1I:2:1 (port 1I:box 2:bay 1, SAS, 900.1 GB, OK)
  physicaldrive 1I:2:2 (port 1I:box 2:bay 2, SAS, 900.1 GB, OK)
  physicaldrive 1I:2:3 (port 1I:box 2:bay 3, SAS, 900.1 GB, OK)

  physicaldrive 1I:2:4 (port 1I:box 2:bay 4, SAS, 900.1 GB, OK)

So in your case, we're missing information... namely the sizes of the logical drives.

But from here, you have an Array of 4 disks, and two Logical Drives of unknown size carved out from that array.
