    Arista PSU Fan Swap

    Anyone had luck in swapping out the stock fans in the 500w model PSU? I picked up a 7050sx and have been trying to quiet it down. With the fan override at 30% the switch itself is quite nice but the PSU fans are a good bit louder and to top it off it’s not a good loud. They’re whiny. The stock...

    Two blown backplanes...

    So I picked up a Supermicro four node fat twin. I brought up one of the nodes just fine with no issues. However, I went to insert a second node and as soon as it made contact it powered up and I smelled the unmistakable smell of burnt electronics. I pulled out the node and investigated...

    Nutanix CE

    Anyone have experience with lots of storage on Nutanix CE? I manage and admin our Nutanix cluster for work and I want to also run it in my home lab. I see the CE has an 18TB storage limit, however they give an example of 3 x 6TB disks. Is this per-node? It doesn’t make sense for 3x6TB disks per...

    NVDIMM Question

    I have some Micron DDR4 NVDIMMs, PowerGEMs, and cables. I’m trying to get them working on a Supermicro X11SPL. Everything seems to be working except for the actual saving process. When power is removed it looks like there is no power provided to the DIMMs. I bought the cables from DigiKey...

    Heads-Up: Supermicro Unique IPMI Passwords

    So, I ran into this tonight with a new X11SPL. Apparently in November 2019 Supermicro started programming in unique passwords for IPMI access. It's no longer ADMIN/ADMIN. The username is still ADMIN, but the password is printed on a sticker on the board. BMC Unique Password Security Feature...

    Supermicro File Index

    Hi All, I'm posting this here with the hope that it will help someone find something they need (old BIOS, firmware, etc.). I know that Supermicro support is quite good and they often provide you with the files you request, but it's sometimes nice to be able to *just get* something at 2AM when...

    Xeon W - X299 Board - ASUS C422 WS Fan Information

    Has anyone had success with running a Xeon W on an X299 board? Based on some discussion in the ES Xeon thread it's just a bit that needs flipped in the BIOS? The reason I ask is because I picked up a cheap (relatively) Xeon W from Ebay and cheap (not relatively) ASUS C422 WS board from Amazon...

    Delta Fan Part Numbers

    Hi all, Does anyone have a reference or know how to decode the suffix for Delta fan part numbers? I'm trying to replace a fan in a switch and even though the major part number is the exact same, the fans behave differently. The part number guide on Delta's website shows how to decode the main...

    Hi All, I have 38 SonicWall SonicPoint Ni WAPs for sale. All are in good working condition. Part number is APL21-083. These would be great to fill in those dead-spots! $75 (now $50!!!) each and I'll entertain offers for multiple units! Also, I have a number (~12) SonicWall PoE injectors. I'll...

    HP ProCurve Lifetime Warranty

    Looks like that for products purchased after December, 2014 they changed it to "as long as the original end-user owns the product". So, it's no longer transferable. That sucks.. :( http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=c04499781 This document says Dec, 2015...

    HBA with cache and BBU?

    Does anyone know if such a product exists? I think such a product would be good to find because I believe it would compliment ZFS. Here is why: 1) ZFS likes to work with disks directly 2) ZFS uses the ZIL to log writes to the pool 3) In the absence of a dedicated log device ZFS will use the...
