March 15, 20197 yr Hi. I have several drvies, about 10 of them. 1 TB SSD Cache, plugged onto motherboard, 1 3TB HDD, plugged to M/B as parity, the rest are a bunch of sata 2 speed drives, 1, 2 TB, connected to Dell Perc H310 controller. I have 4 SAS 3 drives incoming. How do I integrate it to my array? Currently, my HBA controller is flashed to IT mode, where all SATA drives are currently connected, except for 1 or 2, cache, parity. Onboard, I have 6 ports, 2 are already occupied. Does my HBA have to be flashed to a different mode to make use of sas controller? When sas controller flashed to IT mode, can it handle 4 drives of sata, and 4 drives of sas? The sata will be using SFF8087 breakout cables, while the sas will be using a different type of cable, I presume? Both type of breakout cables on the same hba card? If this is possible, shall I group all the sas drive into 1 share? These are brand new sas drives. Do we allow spindown? Any other usage scenarios you can share?

Yes, assuming there's no backplanes. 8 hours ago, jang430 said: Both type of breakout cables on the same hba card? Yes. 8 hours ago, jang430 said: If this is possible, shall I group all the sas drive into 1 share? Not relevant. 8 hours ago, jang430 said: Do we allow spindown? Spindown won't work with SAS.
March 16, 20197 yr Author @johnnie.black, spin down won’t work with sas driveshaft, but will still do on SATA? Even when they are using the same controller? The sas drives I’m about to use are new ones, sas 3.without spindown, will they use up a lot of power?

Look at drive's spec sheet/manual, they usually show power usage in various conditions, including idle.
