How is storage defined on a Apollo 2000 (4 nodes set) ?

We plan to build a new architecture based on Apollo 2000 for HPC.

I would like to know how is storage assigned to different node ?

is storage assigned based on single disk, array or volume ?

can I define a RAID 6 with all the disks and attrib some slice/volume to node or should nodes be assigne his own array or worse his own disk.

 

I guess I have to manage storage on a side an assigne node with PXE or similar. ... by the way it will be linux only on nodes.

thanks for your comments, tips and advices.

regards  

D.

is this forum the right place for this question, or is there a more specific one ?

hyperconverged doesn't seems to fit with Apollo 2000 wich is more HPC or high density.

Hello Dominx,

when designing a Hyperconverged enviroment you could have a Hardware RAID on the lower layer and a Software RAID on top layer.

Storage will be managed by the OS and then presented to the hosts.

There is an interesting Guide that you could have a look to clarify some concepts and definitions:

Dear @Dominix_,

Thank you for your questions.

Node have their own factory default configuration which evenly distributes the 24 SFF drive bays in the HPE Apollo r2800 Chassis as below:

Six drive bays are allocated to each 1U node.
• Node 1: drive bays 1 through 6
• Node 2: drive bays 7 through 12
• Node 3: drive bays 13 through 18
• Node 4: drive bays 19 through 24

Twelve drive bays are allocated to each 2U node.
• Node 1: drive bays 1 through 12
• Node 3: drive bays 13 through 24

Note:  To deploy drive bay mapping configuration (user defined) iLO user account privilege "Configure iLO Settings" is required.

Creating a "single" RAID 6 vlomue for multiple nodes doesn't sounds like a good idea.

You can use Intelligent Provisioning / SSA to configure array and install OS.  Refer  HPE Apollo 2000 Gen10 Chassis - Software and Configuration Utilities

You may check the support Operating Systems and Virtualization Software here

If you have any further question, please feel free to ask them.

 

Thanks and Regards,
