Re: SSD NVMe is not supported for Raid !!

I'm a bit confused. We want to use an all NVMe approach for Ceph and got feedback from HPE that SLES 15 would not support boot from NVMe. Currently nobody at SuSE did confirm this. But I checked the datasheet of one of the NVMes we want to use (this one not for boot) and there is a lot about SAS in it. I don't think SAS is involved with this NVMes, right? It seems also to be a problem to configure a DL380Gen10 with 3 x dual port 10GbE adapters and more than 8 NVMe devices, which is hard to believe.

Re: SSD NVMe is not supported for Raid !!

Hi Swapnil,

Thanks for bringing it up however, I still have a doubt. Will Smart Array S100i SW RAID able to do RAID configuration on NVMe x4 Lanes SSDs in Windows environment. If not, then what is the option or workaround to configure RAID with NVMe SSDs.

Also does the same logic applies to M.2 SSDs or for these we have some different practise. Will appreciate if you can address this.

Apologies for bothering you with too many queries at once.

Thanks in advance.

 Is there an updated link to this document?
<h20195.www2.hpe.com/v2/getpdf.aspx/4aa6-3464enw.pdf>

The link no longer works! 

Is it this document, by any chance?  https://assets.ext.hpe.com/is/content/hpedam/a00040243enw

Re: SSD NVMe is not supported for Raid !!

as you mentioned the only solution to make S.W RAID on LINUX OS for example oracle linux can the created raid drive raid 1 be boorable for the OS ?

Re: SSD NVMe is not supported for Raid !!

Starting February 2021 and Proliant bios update 2.40 there should be an option now to configure software raid with nvme drives. I see the new option in BIOS/Platform Configuration (RBSU) > Storage Options > NVM Express Options. The option name is "NVM Express SmartRAID SW RAID Options" but it's grayed out and I cannot enter that option. What should be done to be able to set two NVMe drives in Raid1 mode?

@kondor , this seems to be an old topic. I think you should consider creating a brand new post
