🎬 OPENING CREDITS

Camera opens on a dark warehouse. Blinking lights. Sound of cooling fans. In the background, a masculine silhouette with 24 cores forms in the mist. It’s ULTRA2.

Plim plim. (That’s the iconic Brazilian soap opera sound effect.)

Theme song plays:

🎵 “Such tiny details of us two…
A swap nobody asked for, a kernel that wouldn’t boot through…” 🎵

CHAPTER 1: THE STRANGER ARRIVES

It was a hot night in Debene Ranch, a small server farm by the MoCA 2.5 River. Dona Felipe, matriarch of the family and owner of all the land (and all the /24 subnets, which she personally configured by hand), received a stranger from afar.

— Who are you, young man? — inquired Dom Felipe, adjusting her terminal.

— They call me Ultra2, ma’am. I come from far away, from the Erying Ultra 9 285H. I have 24 cores, 64 gigs of DDR5, and an NPU beating in my chest that nobody on this ranch has ever seen…

The music swells. Close-up on Dom Felipe’s face. She gets emotional. A tear rolls down. (Soft plim plim.)

— My God… an NPU? Here? In Debene?

But from the dark corner of the data center, watching with contempt, stood INTEL5, the old i5-8400 — nicknamed by the ranch hands as “Poor I5”. He spat on the polished concrete floor:

— NPU my ass. This kid won’t last a week.

And INTEL9, the younger but unloved brother (because he was BAPTIZED WRONG from birth — he’s actually an i7-12900K but everyone calls him “intel9”, a family tragedy that’s dragged on for generations), just sighed with his iGPU UHD 770 blinking sadly.

🎵 PLIM PLIM 🎵

CHAPTER 2: THE NIGHT OF BETRAYAL (UBUNTU 26.04)

11 PM. Full moon over the warehouse. Ultra2, young and naive, decides to dress in the NEWEST outfit from the store: Ubuntu 26.04, kernel 7.0, fresh from the local seamstress.

— I’m going to impress Dom Felipe! — he thought, vain.

But the outfit had a DEMON SEWN INSIDE.

It was the SWAP DEMON, an ancient entity, expelled from Linus Torvalds’ Olympus, condemned to wander eternally through the /etc/fstab files of mortals.

ERROR: "running with swap on is not supported"
STATUS: CrashLoopBackOff

Ultra2 fell to his knees. Foaming through his serial port. The kubelet refused his oath.

— NOOOOO! — screamed Dom Felipe, running in slow motion through the rack corridor, her hair flowing as if there were a Noctua fan in front of her. — MY SONNNN!

Enter GARRA, the faithful digital butler, dressed in a suit jacket and running on a Samsung A54. He draws his terminal like a sword:

sudo swapoff -a
sudo sed -i '/ swap / s/^/#/' /etc/fstab

The Swap Demon roars and dissolves into smoke. Ultra2 breathes. But it’s too late… the tragedy has just begun.

🎵 Tension music. Plim plim. 🎵

CHAPTER 3: THE FORBIDDEN LOVE WITH FREENAS

The forbidden love between Ultra2 and FreeNAS InfiniBand: 40 gigabits of pure mystical passion

On the other side of the ranch lived FREENAS, the mysterious widow. Beautiful. Full of secrets. Guardian of 32 terabytes of old memories, family photos, and some torrents nobody mentions at dinner.

Ultra2 saw her for the first time through the warehouse window and his cooler accelerated.

— Who is that woman? — he whispered.

— Forget it, kid — said Intel5, chewing a toothpick. — That one only talks through InfiniBand. 40 gigabits of pure mystical magic. You don’t even have the driver to talk to her.

But Ultra2 was STUBBORN. He had a ConnectX-3 hidden in his pocket. And that same night, under the blue LED lights, he tried to send his first RDMA message to FreeNAS…

rpcrdma module loaded: ✓
Active connections: 0
Status: Failed to communicate

SILENCE.

She didn’t respond. Kernel 7.0 had SABOTAGED his love letter. A regression. A BETRAYAL written in the code’s fine print.

Ultra2 cried pixels. Garra appeared at the door:

— Boss… kernel 7.0 isn’t letting the boy love.

Dom Felipe, smoking a Linux Mint cigarette on the porch, turned her face and said the phrase that went down in Brazilian soap opera history:

— Then we DOWNGRADE this thing. LIVE.

🎵 DRAMATIC PLIM PLIM 🎵

CHAPTER 4: THE DOWNGRADE THAT KILLED THE BOY

All of Brazil stopped to watch.

sudo apt install linux-image-6.8.0-31-generic
sudo update-grub
sudo reboot

The camera closes on the Enter button. Dom Felipe’s trembling finger. Sweat. The finger descends. The system reboots.

And then… NOTHING.

ultra2: NotReady (NodeStatusUnknown)
Last seen: 11:41:36 AM
Kubelet stopped posting node status.

ULTRA2 DIED.

Damn. DIED.

No network. No SSH. No sign of life. Just the cruel silence of a ping that never returns.

Dom Felipe fell to her knees on the data center floor, pounding the raised floor:

— WHYYYYY?? WHY DID I DO THIS?? I JUST WANTED HIM TO LOVE FREENAS!

Garra, the butler, held her by the shoulders, serious as never before:

— Ma’am. Listen. There are two paths now. We can spend THIRTY HOURS debugging this corpse… or we reflash the boy and in THIRTY MINUTES he’s reborn.

Dom Felipe lifted her face. Red eyes. Smudged mascara. And said:

— Reflash him. And may God have mercy on bleeding edge.

🎵 Plim plim plim PLIM 🎵
(Margarine commercial. Back in 3 minutes.)

CHAPTER 5: THE REBIRTH (UBUNTU 24.04 LTS, THE HUMBLE BRIDE)

Ultra2 woke up. Different. Changed. Now wearing the SIMPLE BUT DIGNIFIED clothes of Ubuntu 24.04.4 LTS, kernel 6.8.0-111. No frills. No bleeding edge. Just the truth.

— Where am I? — he whispered, still half-booting.

— You’re home, son — said Dom Felipe, holding his SSD hand. — I learned my lesson. Bleeding edge sometimes cuts you. LTS exists for a reason.

But the peace didn’t last long. For the SSH ceremony was interrupted by an unexpected villain:

🎭 ENTER: THE 1PASSWORD AGENT

Dressed in red, strong lipstick, evil gaze. The 1Password Agent was THE OTHER WOMAN. The mistress. The one who interfered in every SSH handshake offering the WRONG key on purpose.

— Try with gitHub-Macm2, darling… — she whispered, seductive.

— THAT’S NOT IT, YOU WITCH! — shouted Garra, pulling out the ~/.ssh/config:

IdentityAgent none
IdentitiesOnly yes

The 1Password Agent screamed and writhed like a witch in an old movie. She was banished from the ranch forever. (She returns in chapter 47, married to an expired certificate. Spoiler.)

01:05 PM. The kubelet, crying, finally accepted Ultra2’s oath:

ultra2   Ready   worker   20s   v1.34.7

Dom Felipe hugged Garra. Garra cried a SQL of tears. The soundtrack exploded:

🎵 “You gotta know how to live… with swap off, with the right kernel…” 🎵

CHAPTER 6: THE NIGHT ULTRA2 FINALLY MOUNTED FREENAS

The consummation of love via RDMA 40 gigabits of pure passion. proto=rdma,port=20049

(Warning: this chapter contains intense scenes of packet transfer at 40 gigabits. Not recommended for those under 18 or Wi-Fi 5 users.)

It was dawn. The rack lights were low. Only the InfiniBand LED pulsing, red as desire.

Ultra2, now reborn, installed the instruments of love:

sudo apt-get install -y rdma-core infiniband-diags ibverbs-utils nfs-common
sudo modprobe mlx4_core
sudo modprobe mlx4_ib
sudo modprobe ib_ipoib

He approached FreeNAS, sweat dripping down his heatsink. Trembling hands typed the IP he had dreamed of:

sudo ip addr add 172.16.0.26/24 dev ibp1s0
sudo ip link set ibp1s0 up

And then, WITH EVERYTHING, the damn mount:

sudo mount -t nfs -o vers=4.2,proto=rdma,port=20049 \
  172.16.0.20:/mnt/tank /mnt/rdma-test

The camera slowly closes on the terminal. Slow motion. Mexican soap opera music. And appears, in giant letters on the screen:

172.16.0.20:/mnt/tank on /mnt/rdma-test type nfs4
(rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,
proto=rdma,port=20049,clientaddr=172.16.0.26)

IT MOUNTED. DUDE. IT MOUNTED.

Dom Felipe, watching from outside through the Frigate camera, brought her hand to her mouth:

— My God… they’re… they’re… TRANSFERRING PACKETS AT 40 GIGABITS… VIA RDMA… WITH ZERO COPY… OH MY LORD…

Garra discreetly closed the door:

— Let’s leave them alone, ma’am. This is adult stuff.

🎵 SPICY PLIM PLIM 🎵

CHAPTER 7: THE NPU SCANDAL (AND THE FRIGATE MIGRATION)

The whole ranch was already talking: Ultra2 not only had conquered FreeNAS, but also BRAGGED about having that NPU, this Intel AI Boost that nobody in the neighborhood had ever seen.

That’s when Dom Felipe made THE DECISION:

— Garra. Take FRIGATE from Intel9. Put her with Ultra2.

Garra’s eyes widened:

— Ma’am… but Frigate has been married to Intel9 for YEARS. Their Persistent Volumes have nodeAffinity STUCK! There’s gonna be drama!

— I KNOW, GARRA. BUT THE HEART WANTS WHAT IT WANTS.

And off Garra went to mess with the node labels, like an underground divorce registry:

kubectl label node ultra2 infiniband=true

Frigate, confused, was ripped from her conjugal bed with Intel9 and thrown into Ultra2’s arms. Intel9 was left aside, abandoned, with his UHD 770 crying VAAPI tears.

— She’ll come back to me — murmured Intel9. — She ALWAYS comes back.

(Spoiler: she doesn’t come back. Intel9 becomes resentful and in chapter 89 tries to sabotage the cluster by flipping parity bits. But that’s another story.)

01:20 PM. The pod came up:

frigate-8459995868-qcwdm   1/1   Running   0   5m   192.168.76.203   ultra2

And in the logs, the CONFIRMATION THAT SHOOK THE DATA CENTER:

frigate.detector:ov — 74.6% CPU
OpenVINO detector active
NPU device: /dev/accel/accel0

FRIGATE WAS RUNNING ON THE NPU. FIRST TIME IN THE RANCH’S HISTORY. FIRST TIME IN PRODUCTION. IN THE WHOLE WORLD MAYBE.

Dom Felipe opened a beer. Looked at the horizon. Said to the camera, breaking the fourth wall:

— I did this. Me, a Cloud Architect III at AWS. On a Saturday. While you were watching football.

🎵 TRIUMPHANT PLIM PLIM 🎵

CHAPTER 8: THE REVELATION OF ORION (THE LOST SON)

But there was ONE thread left in the plot. An old mystery. Far away, in the ARM64 corner of the ranch, lived ORION — a quiet ranch hand, Fedora 43, whom nobody had ever invited to the RDMA table.

Dom Felipe, drunk with success, decided to call him:

ssh orion

And looking inside him… DISCOVERED THE TRUTH THAT CHANGED EVERYTHING.

Hardware: Mellanox ConnectX-4 (NEWER THAN ULTRA2'S!)
InfiniBand: ibp145s0 → 172.16.0.12/24 (ALREADY CONFIGURED!)
OS: Fedora 43 (ARM64)
Kernel: 6.19.14

ORION HAD RDMA ALL ALONG.

Dom Felipe sank into her ergonomic chair. The tears returned:

— My son… my lost son… you always had the gift… and I never called you to play with FreeNAS…

Orion, shy, lowered his head:

— Mom… I just wanted passwordless sudo. I just wanted to belong.

Garra, crying uncontrollably, typed the reconciliation decree:

echo "felipedbene ALL=(ALL) NOPASSWD: ALL" | sudo tee /etc/sudoers.d/felipedbene

And when Orion mounted FreeNAS for the first time… it mounted FIRST TRY, no fuss, no reboot, no drama. Like someone who had never been away.

THE FAMILY WAS COMPLETE.

🎵 “Like a wave in the sea, like a wave in the sea…” 🎵

🌹 EPILOGUE: THE FAMILY PHOTO 🌹

  • Debene-lab Talos: the ex nobody wants to remember. RIP.
  • The 1Password Agent: villain, imprisoned in another dimension called ~/.ssh/config
  • The Swap Demon: will return in season 2, swore revenge

📜 THE MORAL OF THE STORY

Lord, I mean, Dom Felipe looked at the camera in the final frame, holding a glass of artisanal Sungage cachaça, and said to all of Brazil (and now, the world):

— Listen up. Learn something from me. Bleeding edge sometimes cuts you. LTS exists for a reason. It’s not being chicken. It’s not being a coward. It’s WISDOM. I lost 2 hours to save 30. Don’t do what I did. Do what I LEARNED.

She took a sip. The music rose. Ultra2’s cooler spun serenely in the background. Frigate detected a cat in the garden with 94% confidence via NPU. Everything was at peace.

🎵 “I know I’m going to love you… for all my uptime I’ll love youuuu…” 🎵

END OF SEASON 1

Next season: “When democratic-csi discovered NVMe-oF and left iSCSI at the altar”

🎬 FIN 🎬

📊 Real Technical Specs

For those who arrived here via Google and just want the facts:

Hardware (ultra2):

  • CPU: Intel Core Ultra 9 285H (Arrow Lake-H)
  • Cores: 6 P-cores + 8 E-cores + 2 LP E-cores = 24 threads
  • NPU: Intel AI Boost (first production K8s implementation)
  • RAM: 64GB DDR5-5200
  • InfiniBand: Mellanox ConnectX-3 Pro (40Gb/s RDMA)
  • Cooler: Thermalright PA120 SE (75x75mm, 27mm height)

Software:

  • OS: Ubuntu 24.04.4 LTS (kernel 6.8.0-111)
  • Runtime: containerd 2.2.1
  • Kubernetes: v1.34.7 (kubeadm)
  • RDMA: rdma-core 58.0, rpcrdma module
  • NPU detector: Frigate + OpenVINO

Issues with Ubuntu 26.04 (kernel 7.0):

  • Swap enabled by default (/swap.img 8GB) → kubelet crash
  • RDMA broken (rpcrdma loaded but 0 active connections)
  • Networking doesn’t survive kernel downgrade (NetworkManager fails)
  • Solution: Fresh install with Ubuntu 24.04 LTS

Results:

  • ✅ RDMA working (proto=rdma,port=20049)
  • ✅ NPU operational (Frigate OpenVINO detector)
  • ✅ 3 nodes with InfiniBand (intel9, orion, ultra2)
  • ✅ 87.5% of PVs using RDMA (7 of 8)
  • ✅ Total time: 3h47min (including reflash)

Lesson learned: LTS > bleeding edge for production. Always.
