R740xd with NVMe drives
Hi all,
I am trying to find what option is better to give best performance:
A - SSD System drives with hardware RAID1 (H730p / H740P) + additional NVMe drives for storage
B - NVMe system drives with RAID1 under S140i + additional NVMe drives for storage.
OS will be Windows Server 2022.
Regards,
JT.

Hello, page 35 may answer you:
https://dell.to/4d3Sqy7
Boot Optimized Storage Subsystem (BOSS) BOSS is a simple RAID solution card that is designed specifically for booting the system's operating system, which supports up to two 6 Gbps M.2 SATA drives. This card has a x8 connector using PCIe gen 2.0 x2 lanes, available only in the low-profile and half-height form factor.

@DELL-Young E
Then, what is the card with NVMe drives shown in this video?

Hi, I don't know, maybe I'm misunderstanding your question, but BOSS card is not M.2 sata. BOSS card is a kind of adapter that allows you to use M.2 NVMe drives in your system. You can take a look this video about NVMe SSDs Overview https://dell.to/4d8TmkF

@DELL-Erman O Thanks for reply but I think you are wrong. As your colleague said BOSS card only supports M.2 SATA drives.
What I am trying to know is what is the best configuration to install OS and maximize the performance to work with 24 x NVMe backplane for storage and 1YGFW cards:
A. SSD hardware raid with H730P / H740P
B. 2 x PCIe add-in NVMe drives
C. BOSS Card with M.2 SATA Drives

Maybe the final question is if a R740xd configuration with 24x NVMe backplane, 2 x PCIe NVMe controller card 1YGFW to enable the 24 slots to U.2 NVMe drives and 2 x NVMe add-in cards with S140 SW RAID for OS would work properly.

@DELL-Chris H
Yes, figure 15 is showing this setup with 24 NVMe backplane + 2 x PCIe NVMe controller card 1YGFW.
Also figure 16 showing 24 NVMe backplane + 2 x PCIe NVMe controller + PCIe PERC controller.
Are you saying that is preferable HW RAID with SSD drives instead of SW RAID with NVMe drives? Please note that I am trying to obtain best performance and IOPS.

If you are basing it on performance and not cost then I would go with the hardware controller, as it has a higher performance level.
You can compare the differences here.
