What RAID configuration I do actually?

You can have multiple logical drives in the array. These logical drives can also have different RAID levels.

For example, this is a set of 6 disks containing two logical drives, each of which is RAID 10 (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)< br /> 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 can also do this (note the RAID5 logical drive):< /p>

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 In this case, we are missing information…that is, the size of the logical drive.

But from here, you have an array of 4 disks, and two logical drives of unknown size.

Recently I have been playing with my recently purchased (second-hand server) (HP ProLiant ML330 G6), and I am a bit confused about its current RAID configuration. I use the HP System Management webpage on the server Do some inspections and notice the following, which in turn leads me to believe that it is a RAID 10 configuration, according to the Smart Array controller.

To confirm, I have 4 slots with 4 1TB drives in them. In the above screen In the screenshot, it clearly points out 1 0.

As far as I know, RAID 10 is a mirrored stripe, as shown in the figure below.

So, if the data is distributed and mirrored on all disks (as shown in the picture above), then why do I Do you see 2 logical disks of 1TB each in the system? Why can’t I see a total of 2TB in a single logical drive, as shown in the picture above?

Edit

Provide other drive information upon request..

In HP, Arrays are physical groupings of disks. Logical drives are a subset of the array and present the actual block devices to your operating system. < p>

You can have multiple logical drives in the array. These logical drives can also have different RAID levels.

For example, this is a set of two logical drives 6 disks, each disk is 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 can also do this (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 are missing information…that is, the size of the logical drive.

But from here To start, you have an array of 4 disks, and two logical drives of unknown size.
