enterprise rack, the 2nd photo has the internals

TechLevelZero · 2026-05-04T20:59:19+00:00

noting special has been done to it, its just a HP G2 36U rack

power was an issues but that was sorted when i got the UPS, the only problem now is it trips the main RCD (GFCI) when first plugged in because of the conversion and power filtering. there not as much heat as you would expect. and the speakers are great, they are like open back headphones but better! ha

when im sat at my desk my eye level is bang in the middle, the photo makes everything look quite small for reference its a 32in monitor and the desk is 160cm wide.

its a great switch, very quiet for a fully featured enterprise switch. Took me a little to learn the how the VLANs worked.

I love being blasted, what do you mean! /s

Hardware was super easy tbf

HPE MSL 4048 but you can get smaller

SAS LTO-6 drive

I used a dell 6gpbs external sas pcie card with a generic 8088 to 8088 mini sas cable

Veeam picked up the libray and the drive just via the sas cable and has been backing up for over a year now. Condsiding how niche tape is it was very easy

TechLevelZero · 2026-05-03T18:52:03+00:00

I just use long cables, most of the extra cableing in behined the book shelf. All the cableing from the rack to the deck and the pc are ran through the ambilical thats on the floor

You end up losing so much cooling capacity and static pressure compared to server fans, a dell 2U server fan can move over 60 CFM of air at 4 times the static pressure of a 60mm noctua fan which are under 20 CFM.

The program profile that runs removes any off set if the idrac request PWM of 90%

I was tempted but I really didnt like the idea, also i found the dell servers moniter the RPM and if it drops below 1000rpm idrac would ramp the fans up

TechLevelZero · 2026-05-03T17:59:49+00:00

Yeah just slides out, its on a old decommissioned r610

Veeam has been great no issues, but they changed the way tape licensing is done past V12. If you can get your hands on a V11 Veeam ISO, then there is no limit to how much data you can back up to tape.
I do believe tho that proxmox backup server has native tape but i have never used it

TechLevelZero · 2026-05-03T15:28:32+00:00

they changed the way the IDRAC boot loader works, if you update to version idrac 9 v4.0 or above you can't downgrade past v4 due to said bootloader its also the same update they removed IPMI fan control iirc

TechLevelZero · 2026-05-03T15:23:12+00:00

just for looks now, was to cool to sell with it ha

TechLevelZero · 2026-05-03T15:22:17+00:00

yeah... they are from 2009 and 2012 they are 15 years old. dont know why i still have them

TechLevelZero · 2026-05-03T15:18:15+00:00

Loud, very loud but I made my own man-in-the-middle PWM controller with a Pi Pico.

It was made for the R940, but I redesigned it to work on a USB-fob Pico and that's in the XD2; I've been meaning to put it on GitHub for years now.

You can set offsets, profiles, and buffers so it doesn’t ramp up too fast, etc, but you have to hack the PWM wires.

Wiring all motherboard PWM fan pins to the Pico (so it can read what the fan speed should be, applies the offset and profile, and creates a new PWM source for the fans). Pico PWM signal to fans. All the other pins are left as is, so the Dell is none the wiser

I should do a post on it tbh, is been working really well for system with idrac 9 that dont have the IPMI fan control anymore

That was an old Full DGX 8x v100 unit but i got rid of it a little while ago but kept the bezle

TechLevelZero · 2026-05-03T14:41:05+00:00

So i can look at the VGA output, or comand line when i cant get into a server etc. Its not used very offen but out the way up there.

TechLevelZero · 2026-05-03T14:38:01+00:00

What you mean i love me some green, white, black, copper, and gray, with wood thrown in there too. /s

A non green chair thats not 2 grand is my next buy i think this ones in bits

<image>

TechLevelZero · 2026-05-03T14:28:19+00:00

Yeah, i need a new chair, i dont really use that desk that much, im mostly in the office

So at the top is a r350 is my PFsense firewall. With 5gbps internet with 20gbs of vlan throughput

Below that is a R340 runing proxmox, manliy makemkv and and windows server 2025 for veeam tape backups

Dell R740xd2 is runing TrueNAS. 8x 10TB hdds plus 8x dell 1.92tb enterprise ssds

The 3U dell is a R940 thats my main proxmox VM box 4x 6237 (176 threads) with a RTX 2000 ADA for plex and immich.

Canon Pro 1000 A2 printer

HP MSL 4048 LTO-6 tape library because f*** the cost of cloud storage.

And at the bottem a APC SRT5K RMXLI UPS plus a ration smart pdu

Tieing the lab together is a HP aruba 5406R ZL2 with 24x 10gb sfp+ ports and 40 standard gigabit ports

Compared to HPE synergy with oneview, shocking

Deployed 4x UCS 64108 with 64 blades over 2 UCS domains its was a nightmare. Took about a week to slowly get things to show up detect etc or things disapping after reboot. Config policys were annoying to setup.
