If you’re looking for a turnkey NAS solution, this system is nearly complete.You just need to add RAM and hard drives. The chassis has the SAS2 backplane so there are no issues with large drives, and the included LSI controller can be flashed into IT mode.
I can’t really answer that question without knowing your use case for the build. If it’s just going to be a storage server, then I would say it’s not worth the upcharge. If you’re going for a VM server, then the extra NICs and memory slots might come in handy. The only other difference between the two boards is the physical size. The LN4F version is the larger EE-ATX form factor, which won’t fit in most cases except these rack units by SuperMicro.
I have a question/problem with this chassis. So I recently bought it and it came with the BPN-SAS2-846EL1 which has SFF SAS ports.
The issue I am facing is I got a Tyan S5512 motherboard which has 8 sata connectors. Can anyone help me with connecting that SAS port on the backplate with the SATA ports on the motherboard?
The only thing I found is “SAS 36P SFF-8087 to 4 SATA” however like the description says, it is to 4 sata ports and the backplate has only 3 SAS ports. If my math is correct, each SAS port should map to 8 ports so I can connect up to 24 disks.
Also, that backplane has a built-in expander, so technically you would only need a single reverse breakout cable to access all 24 drives. You could add a second cable to increase the aggregate bandwidth, but that’s optional. The third port on the backplane is for daisy chaining another expander, if you ever needed to expand beyond 24 drives.
