Hi Brent, at this moment the storage servers have less disks, but for today EOD I could try to get the disk that are missing and fulfill the requirements.

Arce,
 
For a minimal ceph config you will want 5 nodes.
 
- 2 controllers
- 2 computes 
- 3 storage nodes 
  • Dual socket xeon, min 16 cores 
  • Min 64GB RAM 
  • 4 disks preferably SSD’s. 3 for OSD’s, 1 for the root disk 
 
The CEPH monitors will run on the controllers and the 1st storage node to provide the quorum of 3.

Subject: [Starlingx-discuss] CEPH Based Testing Options
 
In today's "Weekly StarlingX non-OpenStack Distro" [0] there was a requirement for our validation activities around CEPH so we need your help to learn more about the specific hardware.
 
StarlingX allows a flexible storage options:
 
1. Linux Logical Volume Manager
2. CEPH
3. External SAN
 
[ CEPH : StarlingX Dedicated Storage ]
 
StarlingX system can be configured as Ceph-backend storage (Controller) and have available N number of Compute and Storage hosts, today we are deploying this as a "Dedicated Storage" configuration [1] :
 
- 2 Controller Nodes
- 2 Compute Nodes
- 2 Storage Nodes
 
[ CEPH : Homepage Documentation ]
 
Looking at the Hardware Recommendations from CEPH Documentation, they list N number of components including requirements for CPU, RAM and a bunch of storage devices (Hard Disks, SSDs) [2] StarlingX provides this provisioning automatically if "Dedicated Storage" is configuration chosen.
 
[CEPH : Specific Hardware ]
 
Can you please guide us on what does that specific need makes it unique?
Is it a hardware? Is it a configuration? Is the mix of both?
 
1. Is StarlingX "Dedicated Storage" configuration one of the 2 possible CEPH based testing options?
2. Do we need a separate CEPH cluster provisioned including their own OSDs and monitors?
3. Any other?
 
We would appreciate any link to information and architecture to learn more about this request.
