Cabling for SAS controller and SuperMicro BPN-SAS-825TQ

jp flag

I´ve managed to get one of the SuperMicro low-end server to my lab. It is chassis 825TQ-R740LPB with a BPN-SAS-825TQ backplane. The specification document is saying, that this backplane is SAS compatible. But the server has a motherboard with only a SATA controller. All 8 SATA ports from the motherboard are connected to the backplane´s SATA ports.

Now, I want to use SAS disks in that enclosure. I have a spare HP P410 Smart Array card, so I am thinking about using it. What is not so clear to me is the connection from the controller to the backplane. Normally in HP backplanes, there are miniSAS ports, so I am using cables like this one (https://www.amazon.com/HP-579265-001-Mini-SFF-8087-Cable/dp/B00H7B34EY) to conenct the backplane with the controller. But on the BPN-SAS-825TQ, there are only SATA ports. Do I understand correctly, that if I use this cable https://store.supermicro.com/supermicro-internal-minisas-to-4-sata-50-50-50-50cm-with-sideband-50cm-cable-cbl-0097l-02.html (actually two of them) together with the P410 RAID controller, it will be possible to use SAS disks in that enclosure?

HP P410 has mini-SAS (SFF-8087) connectors, so you can use Supermicro CBL-0097L-02 or CBL-0176L-02, or any other SFF-8087->4x SATA cable except crossover ones.

Seconding that - if the backplane has SATA connectors you need a SFF-8087-to-4xSATA fanout cable (or two), regardless of whether you run SAS or SATA over that cable. There are even SAS RAID controllers (and possibly HBAs) with all SATA connectors.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
