Is a NVMe m.2 to miniSAS a good idea?

[Faccin0]

Hello forum,

I'm thinking about building my own DIY server/nas for home and I'd like to use this as case:

https://www.silverstonetek.com/product.php?pid=861&bno=0&tb=44&area=it

 

The point is this: the disks are in two enclosures of 4 disks each and they use miniSAS ports (sff-8643) to communicate with the MB. These miniSAS port are my concern since I've never worked with them and the pcie adapter are expensive (and I'd prefer keep the pcie x16 unit for future network upgrade).

 

My idea is to use an adapter like this one: https://www.delock.de/produkte/G_62721/merkmale.html?setLanguage=en

 

Have anyone of you had same experience? Any suggestion?

 

ps: this is the MB I'm planning to use:https://www.asus.com/Motherboards/PRIME-B360M-C/

Is the second enclosure a disk shelf or are you looking to drive the disks directly just outside the chassis?

 

Situation 1: I don't know if the M.2 slot is compatible with the same SAS/SATA protocols used on HBA's & RAID controllers when using a disk shelf. You'd basically be extending the PCI_e connection with no SAS/SATA controller between it and the disk shelf which I can't say how well that'd go.

 

Situation 2: I am uncertain if this would work. Weather the PCI_e controller behind the slot is directly compatible with the protocols normally handled by SAS/SATA or if bifurcation support will even allow for a SFF-8643 breakout cable to run 4 drives directly without a said SAS/SATA controller.

 

Those adapters are really meant for running 2.5" PCI_e SSD's. You may be able to run one to an appropriate backplane splitter that breaks the x4 down to x2x2 or x1x1x1x1 but if I had to guess I'd say what you're looking to do here won't work.

Thats an adapter from m.2 to u.2 or pcie.

 

IT won't work with a sas drives or a sas to sata adapter.

 

 

You need a hba to use sata/sas drives, like a dell h200

Thank you guys for the answers! I thought it won't work because the lack of controller within...

 

Then I need to make more research because such PCI_e adapters are all around 300€.
