    Micron's "Power loss protection for data-at-rest"?

    Power loss protection for data-at-rest... what exact do they do there? I have an Intel DC drive that has a SMART attribute counting the PLP capacitor tests. I have a Micron 1100 drive here which claims to have it this Micron thing and SMART has no such attribute. Is that anything useful at all?

    HGST 0T01343 3.82 TB U.2 drives any good?

    There is an ebay seller which is dumping them with no reserve and they sell around $100 for 3.82 TB. I am tempted but I don't know much about these drives. I would want 4 of them to serve PXE/NFS in a mirrored, striped ZFS: https://www.ebay.com/itm/404244423515 (no affiliation) (yes I know...

    Njetworking with X540/X10DRI-T4+, no carrier without switch

    I'm trying to set up networking between two X540 units, one is a Supermicro X10DRI-T4+, the other sits in a Z390 Asus Prime board, using a direct ethernet (cat8, 15 feet) cable. I just can't get a carrier under Linux and FreeBSD, even when setting speed and duplex by hand on both sides to 1 GbE...

    "Dual-use mini SAS HD" == U.2?

    Not quite getting the U.2 thing, still. If you have a mainboard with "Eight (8) SATA 3.0 ports or 2x NVMe dual use interface (Mini-SAS HD)" such as the SM H11SSL, is that two U.2 connectors?

    AM5 and DDR5 ECC UDIMMs?

    Since we have the other two threads about the UDIMMs and Alder Lake already: Any indication whether the DDR5 ECC UDIMMs actually work in current AM5 mainboards? The 7950X3D coming out tomorrow looks like a good choice, especially from a power standpoint. Just whether the mainboard makers...

    Ethernet controlled power strips in 2022?

    Are there any recommendable power strips with ethernet control (preferably ssh) available anymore? I can't seem to find anything but single-outlet wifi gizmos. I am so desperate I would even re-buy my Ubiquiti mPower-Pro, although they are not very reliable.

    SAS cage and AHCI unwilling

    I have this Silverstone SAS cage. https://www.amazon.com/gp/product/B01C5TG82C/ref=oh_aui_detailpage_o08_s00?ie=UTF8&psc=1 It seems to work on a random non-JBOD SAS controller, but when using with AHCI SATA controllers it won't. I tried Intel onboard SATA from x58 and I tried an AHCI PCIe...

    WTB: what happened to all those 48-core quad-socket g34 systems?

    I am browsing Ebay for some time to snipe a 48 core quad g34 system. There should be a lot of those left over from the early bitcoin and folding at home hypes, no? So far I have been disappointed. Anyone got one for sale? Or want to trade for something more modern? I'd pay significantly more...

    Electronics for a battery->USB (aka external USB battery)

    I can't find a USB brick I really like. The biggest problem is that all units I tried (~7) have the same problem. Depending on how own-charge or to-be-charged power goes away they stop charging the USB device at some point. They have a "power button" that you have to press to get them back to...

    Redundant power supply - made from regular ones?

    This has never been quite clear to me: Why can't I buy an electric controller unit that makes a redundant PSU out of two regular ATX PSUs? I tried settling for dual units in ATX casing but I'm not comfortable with the noise potential and the fact that I will have difficulty finding replacement...

    What would you do? Stay 1366 or go 2011/ddr3?

    Given the following set of hardware, would you resume going to lga2011/ddr3 or stick with 1366 until moving to DDR4? lga1366 gear: - two SMP combos, one slightly damaged (some RAM slots not working) - several single-processor combos (nagging me due to low RAM but nice for random things)...

    Separating heavy CPU usage from storage?

    I'm a firm believer in keeping computers that hold lots of important storage corruption-free. ECC only, try hard to use server-class mainboards, best PSU you can get etc. etc. Now, re-organizing my network I realize that I do a lot more video processing now, involving encoding. Wish I didn't...

    Long-winded storage overthinking thread (chassis, mostly)

    What would you do? Can't make up my mind. I need to add storage and the physical location question - what kind of enclosure - is killing me. Traditionally, my storage comes in three tiers: My main workstation has a 5-disk SATA frame for data the workstation works on. This functions very well...

    What the devil is it with the PCIe slot shields?

    All three are PCIe cards. The middle one has a shield that is going the wrong way. Is that for a riser card situation in a rackmount? Any hope I can get a regular shield? This is a supermicro SAS controller. Thanks so much Click for 4000x3000 Click for 4000x3000
