HPE and Dell Raid Controllers - No JBOD mode and CEPH

[JakeBikeIT]

Hi All,

I have three really powerful systems including a Dell Epyc that do not have available JBOD.

I can serve up individual Raid-0 Disks for CEPH -

Is this supported please?

Is there another solution to create SDS on such enterprise grade systems or another method for HA storage without a SAN?

Could you please share the details of your Dell hardware? Have you the S150 or the PERC?

virtually all PERCs of modern flavor can do passthrough. check your manual.

While it's true PERCs do support HBA passthrough, they use the megaraid driver. Whereas, a Dell HBA, like a HBA330, uses the much simpler mp3sas driver.

I swapped out all PERCs from 13th & 14th-gen Dells and replaced them with HBA330s. No issues.

Why is this important?

Why do you have a problem with the Megaraid driver?
Many storage virtualizations, both closed and open source, explicitly support these controllers with this driver.
