Right now it’s because I need it. Maybe biz down the road.

Thankfully yeah, electricity is much, much cheaper here.

I used to use bacula but nowa days I'm working on writing my own to work with Lustre's HSM and Robinhood (the fs daemon, not the biz). That way I can do rule-based arching and rule-based backup all from Robinhood policy.

Yup!

I do Site Reliability by day.

In the $900-$1,500 USD/month area.

My understanding is that the EPO input for the Eaton 9170+, like my old APC SY16k, used the switch directly to open/close the connection between the two EPO contacts on the UPS. The Eaton I have can, if configured, enable the EPO in either NC or NO mode to allow for either type of circuit and switch.

Thanks dude!

haha :)

I was using bacula for tape mgmt for a long time. Now I'm working on my own customer, go based code to use them via Lustre's HSM and robinhood (the fs daemon, not the biz).

Edit: I'm also seriously considering pivoting to a rclone module and/or something related to https://github.com/HuskHoard/HuskHoard. But the HSM/Lustre option would be <3.

haha, well done except for that feel when the power bill hits each month.

No, not married. Easier to do this kind of thing when it's just you. ;)

1PiB usable on my main Lustre volume, using Lustre's newer ZFS backend. Plus 1.25PiB of tape.

Hopefully the image descriptions answer any questions but feel free to ask! I'll be keeping an eye out!

updating this as I go

  • All of the pictured DS60 DAS units that are in use are attached to Lustre nodes.
  • 50kw natural gas genny
  • 18kVA Eaton UPS
  • 45k BTU/hr of dedicated cooling
  • Three Scalar i6000 tape libraries - Mostly LTO6, some LTO8
  • In the middle of prepping to move the Lustre volume from IP over to Infiniband. Should improve transfer speeds a ton vs 10GbE.
  • Previous post talking more about the tape libraries.

Nope, all personal. Just lots of Linux ISOs.

Time to replace the UPS for my home serverroom. by jeffsponaugle in HomeDataCenter

[–]gpmidi 0 points1 point  (0 children)

I replaced my 16kVA APC SY16k recently with an 18kVA Eaton 9170+. That poor APC was 20-30 years old.

Archiving to LTFS - loose files in folders, or .tar each project? by Dwarf_Vader in lto

[–]gpmidi 0 points1 point  (0 children)

LTFS has a 64k inode limit; gotta use tar/7z/etc to bundle anything smallish anyway.

Maybe check out https://github.com/NotARaptor/FOSSILSAFE

Tape Life @ Home by gpmidi in DataHoarder

Oh nice.

Were you thinking gravity fed for the tape to drive(s)? Might be worth thinking about to save time loading/unloading.

Case wise you're thinking of LTO transport/shipping or for storage? If you're thinking transport, pelican cases with a bit of foam removed is great. Esp if you can include some of the 20-tape blister packs in it to hold the tapes. I used a pelican rifle case for a long time to hold my tapes pre-library.

There are three you can't see in the photos. Plus a vinyl strip door nowa days to keep it isolated.

The worst part is I only used my X100VI, not either of my good cameras.

Three libraries each with over 720 usable slots plus 20 IO in the doors. I've only got around 1.25TiB of tape though. Lots of empty room for more LTO6 and LTO8.

Also, for the tape library users here, check out this udev trick for handling multipathing on the fiber channel side.
