    LSI 9207-8i BIOS question

    I have two servers, both running Debian 12. Server 1 has a single LSI 9207-8i HBA and server 2 has 2, 9207-8i HBAs. All 3 HBAs are flashed to IT mode with the P20 firmware. What I can't figure out is how to delete the BIOS for the HBAs in server 2 (showing 07.39.02.00 for BIOS). Server 1...

    LSI 9201-16i vs LSI 9400-16i

    Trying to decide between these HBAs (will be using IT mode). I can get the 9201 for $130 on eBay and the 9400 for about $200. I have 12, spinning rust SATA drives that I need to hook up. Using Debian 12, MDADM configured for RAID 5. Have a Rosewill case and will be plugging the HBA straight into...

    Urgent help and advice needed please, power supply suffered massive failure and now some of my drives are gone

    THANKFULLY, this wasn't my main server but it was a secondary server that I back the main one up to and it needs fixed ASAP. It was a 4U Rosewill server (RSV-L4412U), using a Gigabyte ATX board and a Seasonic power supply. It's been humming along for years with zero problems and then today, the...

    Any benchmarks that show resilver time that compares Linux MDADM vs a hardware card?

    Been using Debian on my Plex server for a while. Whenever I add drives to expand the array, disk I/O takes a nose dive as MDADM eats up everything and Plex struggles to stream a single show. I don't know enough about Linux (or MDADM) to issue commands that instruct it to yield disk I/O to...

    Quieting a 846E16-R1200B

    I have a Gigabyte motherboard in this case and I installed dual SQ 900W power supplies. I replaced the 3, stock back wall fans with these: FAN-0074L4 (5K RPM) and it still has the factory, dual exhaust (loud) fans. I was thinking about using these for the exhaust fans: FAN-0104L4 (2800 RPM) but...

    Is this a reason why a dedicated RAID controller would be better vs. MDADM?

    Using Debian 10.4 and I have a software MDADM RAID 6 array formatted as XFS. Zero complaints BUT, I think I read that during a weekly scrub if MDADM detects an error in a RAID 6 setup, it doesn't hold an election process and just assumes the parity drive is always correct. If that is correct...

    What can I do to fine tune my 10Gbps network?

    I have two boxes (running Mint 19.2 on both) using 10Gbps Mellanox X3 cards connected via a DAC cable and iPerf reports 9.8Gbps both ways. No networking switch between these boxes.... just the DAC cable. Server A is a 24 bay, SuperMicro box. I think I have 12, 4TB drives in RAID 6 via MDADM...

    LSI 9240-8i still a great choice for simple RAID 1 in Linux?

    I want to use a hardware RAID card for my boot drive in Linux. I know, I know.... MDADM. Well, I already use MDADM for RAID 6 in my media server but I want to do hardware RAID 1 for the boot drive. (Running Linux Mint 19.2) Reason I want to use hardware RAID for the boot drive is because while...

    Quiet exhaust fans for SC846E16-R1200B?

    I'm going to replace the stock fans in the mid-wall with some 0074L4's but can somebody recommend some "drop in replacements" for the 2 exhaust fans that aren't as noisy as the stock ones? My i7 7700K is actively cooled and I'll be using a mix of 5900-7200RPM drives. My HBA has a small fan...
