P410i: multiple LDs "striped" across physical devices?

On a Dell Perc, i can set up multiple striped/mirrored logical drives on a set of physical drives (i've done it with RAID5 anyhow).  Is this possible in ORCA on P410i?  The system i'm experimenting on (P410i w/o cache) only appears to allow creation of a single LD on a selected set of drives.  I want to build 4x RAID10 LDs on a set of 4 SAS drives.

 

tia!

Hi there,

 

HP P410i controller with Zero memory support only two logical drive. You need to upgrade the 256/512 Cache to enable multiple logical drive creation and other advance feature. Please refer quickspecs for more info.

 

RAID Support

RAID 6, 6+0 (Advanced Data Guarding)
NOTE: RAID 6, 6+0 can be enabled with either

  • Minimum of 256 MB cache, Battery kit and Smart Array Advanced Pack License key option upgrades
  • Minimum of 512 MB BBWC/FBWC and Smart Array Advanced Pack License key option upgrades

RAID 5, 5+0 (Distributed Data Guarding)
NOTE: A minimum or 256 MB cache and battery are required to enable RAID 5, 5+0 support of the Smart Array P410iRAID 1+0 (Striping & Mirroring) RAID 0 (Striping)

 

Logical Drives Supported Zero Memory, Up to 2 logical volumes

Re: P410i: multiple LDs "striped" across physical devices?

Thanks for that, Attab. Can you verify that with cache installed, it's possible to stripe multiple LDs across drives ie: not LD's across whole drives but something like, given a 4 disk setup:

1 2 3 4
0 0
1
LD0 LD0 LD0 LD0
LD1 LD1 LD1 LD1
LD2 LD2 LD2 LD2
LD3 LD3 LD3 LD3

cheers,

Re: P410i: multiple LDs "striped" across physical devices?

Hi,

 

Let me understand your requirement with the small explanation:

 

Array = group of physical drives

 

Lets say you have 4 hard drive in Array A

4 hard drives supports = Raid 0, 1+0, 5 and raid 6.

 

so you have Raid 1+0 (mirror and striping), Raid 5 = Distributed Parity with striping (N-1), Raid 6 = double distributed party with striping (N-2) option available

 

And you can create multiple Logical drive with different raid level within the same Array provided you don't use the entire space while creating a logical drive.

 

So basically we can devide the total harddrive capacity into multiple logical drive within the same group (array)

Refer to HP Guided troubleshoting : http://h20584.www2.hp.com/hpgt/guides/select?lang=en&cc=us&prodTypeId=329290&prodSeriesId=3883890&lang=en&cc=us  for information.

 

 

let me know if I understood your requirement correctly.

Re: P410i: multiple LDs "striped" across physical devices?

Exactly, and in fact i was able to create multiple RAID1 LDs on 2 drives this morning using the Offilne Array Configuration Tool, even lacking cache. ORCA wouldn't allow it, though. Of course, it was just a test - i intend to install proper a flash-backed cache module when i get the HDDs to facilitate RAID10. Thanks very much.
