    Supermicro 846 SQ PSU compatibility

    Just a follow-up for posterity, I came across some good information. The PWS-920P-SQ will work with the PDB PT846-8824 according to random dudes on the internet as well as Supermicro support. PWS-1K28P-SQ and PWS-1K41P-SQ require the PDB-PT846-2824 board. Prices for PDB parts were surprisingly...

    Supermicro 846 SQ PSU compatibility

    I'm wondering if anyone else has encountered this before, just a shot in the dark. I've contacted Supermicro support, I'll see if they can get back to me on this. Basically, I'm looking to use one of the SQ-series PSUs (e.g. PWS-920P-SQ, PWS-1K28P-SQ or PWS-1K41P-SQ) in my 846E16-R1200B...

    27tb zfs with Dell 9th gen hardware

    Nice. Less to worry about then it seems. I think I've done well so far except for the idea of growing the pool by growing mirror vdevs one by one. Data isn't terribly well-distributed across vdevs. It isn't necessarily causing performance issues for me at this point, but I'm in the middle of...

    Fake fan tach signal?

    So here's a thread that's a bit over a year old that shows precisely what I think I'm after. I have a Dell drive enclosure where I just want to pretend as though the jet-engine fans are still present. I'm not an electronics guy and don't trust myself to put together a device like pictured in the...

    Confirm configuration for 2950/MD1000/ZFS

    Hey there, thanks for the reply. I have some more info I can add along the way here, but you might also be interested in a later post of mine, where I have this thing more fully-baked: 27tb zfs with Dell 9th gen hardware You mentioned not being too hot on mirrors above, and originally I was in...

    27tb zfs with Dell 9th gen hardware

    It is. I've read that for zfs you want to make sure to have ECC RAM instead of a single stick of consumer RAM for example (i.e. a glitch in RAM will cause zfs to perceive or write checksum errors) ... but I haven't given it much thought. Performance bottleneck is still the network connection...

    27tb zfs with Dell 9th gen hardware

    Thought some of you folks might enjoy. It's my first time storage build, I think this has gone well so far... Dell 2950 gen 2 Xeon quad-core 3.0ghz 8gb RAM Perc 5/i - 2 x 500gb WD Black in Raid-1 - 6 x 1tb WD Blue in Raid-10 Perc H200 (flashed to IT mode) - SAS cable to MD1000 below Dell...

    Confirm configuration for 2950/MD1000/ZFS

    Looks like this is my jam.. H200e SAS HBA / 8 Port (2 x External SFF-8088 Connection) Plain HBA Card... If I've got the plain HBA card, no need to reflash, yes? Just grab a mini-SAS to SAS (8088 to 8470) cable to go with it...? Getting closer, I can smell it...

    Confirm configuration for 2950/MD1000/ZFS

    Good stuff, thanks for the reply. After looking at it closer I discovered what you mentioned above that the H200E is an LSI 2008-based chip, which is apparently the way to go. I'll pick one of those up. I know the H800 card and various other Dell cards had the "Dell-only disks" restriction...

    Confirm configuration for 2950/MD1000/ZFS

    Hi all- first post, been lurking and admiring for some time and thought this was a good time to join in. I'm not super well-versed in hardware let alone large storage solutions, so I figured this would be a good way to learn some new tricks. Currently I have an 8-port Dell PE 2950 and...
