    Amazon AWS EC2 Mac Mini Powered MacOS Instances Launched

    Yes, apple is selling products that consists of hard- and software. Decoupling the software from the hardware would hurt the brand.

    LSI SAS3008 HBA high temperature ?

    This is the max. ambient temperature. The asic/cpu can get up to 80-90°C before sensors and alarms goes off. https://www.broadcom.com/products/storage/raid-controllers/megaraid-sas-9361-8i

    EU WTB: Superdom (satadom?)

    Why? Satadoms are great, you don't lose high performance pcie lanes for a boot device, don't take up two hotswap bays and still benefit from the random io performance of a ssd.

    Mellanox ConnectX-3 40GbE QSFP breakout cable to 4 SFP ports on 10GbE switch?

    I had a similar experience with conect-x3 nics, I think it's because the nic firmware doesn't know the "new" specifications for 25/50/100GBE transceivers in dacs/aocs/optical modules.

    Supermicro NAS Upgrade

    About 836 vs 846: I have a 836 and a 846 and if I get another chassis it will be a 846 again because it's "stoage density" is better (24 devices/4u vs 16 devices/3u). Another point for the 846: there are more (sas2 AND sas3) expanders available on ebay than for the 836. Edit: "A" (sas multilane...

    New Microchip Microsemi Adaptec SmartRAID 3162-8i RAID Adapters

    Firmware v3.21 + driver v106.190.4.1062 + maxview v3.06.23821 can't handle any storage configuration in windows or pcie changes (adding/removing or moving pcie devices to another slot); the logical drives will disappear and only show up after saving the configuration in the bios. I can...

    Whether expanding or replacing Lab

    Not sure if you consider a single socket comparable: I am running windows 10 pro for workstations on a x10sra with a xeon 1630v4, 64GByte ram and a 1080ti (got it for free :P) and play occasionally fps (doom/doom eternal, csgo and the wolfenstein games). So far no differences to a consumer system :D

    ~2.6M iops on a single core at QD128 with optane and io_uring (linux)

    2.58M x 512 Bytes = ~1.23 GByte/s, that's really impressive for a non nvdimm blockdevice. I'm curios what numbers are possible with random writes. (I was kinda disappointed of first gen optane nvdimms https://arxiv.org/pdf/1903.05714.pdf & First Optane Performance tests show benefits and limits...

    Supermicro 4U Jbod connector

    It depends how the backplanes are wired :D There are two backplanes, one has 3 multilane sas ports, the other has 2 multilane sas ports. In the 36 bay version I would connect the second backplane with a single cable to the third multilane sas port on the first backplane and then route the two...

    Supermicro 4U Jbod connector

    Testing would require enough storage devices that could saturate a single link. I would just look at the controllers link status & enclosure info: (This is from my Adaptec/Microchip raid controller)

    Supermicro 4U Jbod connector

    It's often described/explained as "dual link" : two multilane sas ports on the hba/raid controller connect to two multilane sas ports on the backplane increasing the total bandwidth between expander and hba/raid controller.

    Supermicro 4U Jbod connector

    That's only true for empty hdds when data is written to the outer sectors. That's why all the datasheets say "up to" or "max" xxx MByte/s. The more data is stored, the slower the drive becomes. Example seagate exos 16TByte: empty ~245MByte/s, ~80% full ~100MByte/s, ~95% full <70MByte/s Edit...

    Formatting to 4096 bytes, does it matter?

    "It depends", 4KByte sectors are more efficient, see Advanced Format - Wikipedia I would not try to format hdds that use 512Bytes NATIVELY, the firmware probably won't recognize the drive after the format. I don't know if broadcom raid controller support ssds with sector sizes over 512 Bytes...
