Ich würde im Server-(Haupt-)Gehäuse die interne backplane über einen LSI 9305-16i anschliessen (über drei SFF-8643 zu SFF-8087 Kabel), die anderen zwei externen JBOD Gehäusen über eine LSI 9305-16e anschliessen (jeweils dual link über zwei SFF-8644 auf SFF-8087 Kabel je Expansion JBOD Gehäuse). Beide Karten sind PCI v3 8x und hätten genug power. Nimm PCIe v3 und SAS-3 Controller damit du intern und extern mehr speed und Bandbreite hast. In den JBOD-Gehäusen könntest du jeweils einen slot blech Adapter verbauten (extern SFF-8644 auf SFF-8643) und dann intern wieder SFF-8643 auf SFF-8087 zum backplane gehen (dual link). Von Supermicro gibt es dafür direkt ein slotblech Adapter von SFF-8644 (extern) auf zwei SFF-8087 Kabel, die dann direkt auf die backplane gehen. Dann nimmst du insgesamt 4 SFF-8644 auf SFF-8644 Kabel, 0.5m lang. Wäre die sauberste und professionellste Lösung.

Exactly, wont catch up. Got replaced by NVMe over U.2 and U.3

Anyone with some WD120EDAZ drives wanting to part with, please let me know. Preferable in the EU. Thanks a lot.

yes, or run the command from a VM on another host that stays open.

dd bs=1M if=/dev/zero of=/dev/mdXp1 status=progressI have 6.12.10, so the above should be the right command to zero the disk, right? X is the disk number, ofc. Do I need to run dd in Maintenance Mode or not really?

Asking basically how exactly to clear (zero) the disk, before I configure it out of the Array? Everything else is clear to me.

Yes, I will do it manually. Did it lots of times in the past. Forgot whether the disks need to be zeroed (dd) or something else, before I re-create the Array without the disk.

There was a way to remove a disk from the Array (new Config and leave out the disk-to-be-removed) without parity recalculation. This is needed in order not to be exposed without parity (and protection) during a rebuild. How should I prepare the disk to be taken out? Anyone remembers the procedure?

Have now three PCIv3 LSI 9300-8i in IT-mode in the PCIe 8x slots and everything is running fine. Didn't use the onboard SATA ports as the SAS ports are hot pluggable as well as 12Gbps on the LSI 9300-8i.

Thanks a lot, going for it. Will mate it with an Intel Xeon E5-2680 v4

Hi there, any experience with the Supermicro X10SRI-F board running unRAID? It is an LGA2011-3 Single Socket Intel C612 ATX DDR4 1TB Mainboard Cheers starcat

Researched the AOC-SASLP and SAS2LP and it looks like they do not work reliable, or at all... Looks like the LSI 9211-8i (PCIe x8) is still the best option today? Firmware P20 and running in IT-mode.

Hi guys, running an old Supermicro X7SBE mainboard with two Supermicro AOC-SAT2-MV8 PCI-X boards for 2x 8x SATA devices. I would need to connect one more HBA for another 8x disks and as the mainboard has one unused PCI-E 4x and one PCI-E 8x, I was thinking of an additional LSI 9211-8i (IBM M1015, flashed) HBA or maybe a Supermicro AOC-SASLP-MV8 (Marvell 6480 host controller) Supermicro AOC-SAS2LP-MV8 (Marvell 9480 host controller) What would you recommend as the best option today for this setup? Running unRAID 6.12.10. Thanks a lot for any hints.
