Any idea what Dell is actually selling them? The DVR's we buy (Avigilon) are white Dell 7x0's with a custom white bezel, but those only fit 18 3.5" drives.

Could be the MD3060e with an R650 server? https://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/DellStorage_MD3060e_Dense_JBOD_SS.pdfu https://i.dell.com/sites/doccontent/shared-content/data-shee...

  Your link 404s, I think it's the extra character on the end.

I’d love to know this as well. Dell doesn’t have anything remotely close to what Backblaze was designing/building themselves. So did they do something custom (unlikely at this volume) or did Backblaze change their hardware approach?

  Not quite the same, but they do have something like the Pods, but a bit more modular: It's their PowerEdge MX platform, which allows you to slot in different "sleds" for storage/compute etc. as needed. It can take 7 storage sleds for a total of 112 drivers per chasis.

Based on the pictured bezel, it looks like they've got three rows 3.5" 14TB SATA drives up front in 14th generation carriers. Best guess would be something like an R740XD2 which has 26 total drive bays per 2U.

Dell's densest server is the PowerEdge XE7100 [1] (100 3.5" drives in 5U) but the bezel cover picture looks like more like a standard 2U, maybe a R740xd2 (26 3.5" in 2U).

    That is really interesting ... We deploy our storage with a 2U "head unit"[1] that has the actual computer and all of the SSDs for boot and SLOG and L2ARC and "zfs special"[2] devices. Then we attach 60-drive JBODs externally to those "head units". With this dual-front design you could have 24 2.5 drives in the first row and 12 3.5 drives in the second row and that would really be helpful when we sometimes need to quickly spin up an adjacent zpool without attaching another whole JBOD. Sadly, I do not see any configurations with 2.5" drives on the Dell config page: https://www.dell.com/en-us/work/shop/dell-poweredge-servers/poweredge-r740xd2-rack-server/spd/poweredge-r740xd2/pe_r740xd2_13235_vi_vp https://www.dell.com/en-us/work/shop/dell-poweredge-servers/... If one row was 24x 2.5 drives and the other was 12x 3.5 drives I think we would start deploying these immediately ... EDIT: Huh ... even the two, rear, boot drives are 3.5" which is sort of weird and gratuitous ...

    That looks like 13 drives per U (26 in 2U); weren't the BB pods 15 drives per U (60 in 4U)?
    - chx 5y ago
      Up to Storage Pod 5.0 they used 45 per 4U, 6.0 was 60 indeed but it was hanging out from the rack so it is understandable no major OEM has a chassis like that. 52 serviceable drives is not bad at all.
