iiinova — where your digital self keeps evolving

Enterprises don’t buy operating systems. They buy time. Time between forced changes, time to certify, time to amortize hardware. Twenty years of Linux LTS proved the model. What it takes to bring the same guarantee to FreeBSD: article linked below.

[1/3] Final day at SNIA SDC '26 in Santa Clara, with one more technical takeaway from our team. As storage gets faster, the fixed software overhead of each I/O request becomes a larger part of the total cost. 👇

Klara Inc @klarainc.bsky.social · 29/09/2026

[1/3] Day 2 at #SNIA SDC ’26 is underway in Santa Clara, and our team has two more technical takeaways to share. 1. Memory tiering: Memory used to account for around 30% of the cost of a server. Now it accounts for more than 50%, yet most VMs never use half of the RAM allocated to them. 👇

[1/4] Day 1 updates from the floor at SNIA SDC ’26, happening this week in Santa Clara. “Characterizing and Emulating FDP SSDs with WARP” looked at how to understand and test Flexible Data Placement (FDP) in a reliable, vendor-agnostic way to determine why write amplification occurs. 👇

Klara Inc @klarainc.bsky.social · 28/09/2026

For years, zfs set dedup=on was the most expensive command in storage. When the dedup table outgrows RAM, every write turns into random table reads. Fast Dedup in OpenZFS 2.3 changes the math, but you still have to do the math. Part 1 of ZFS misconfigurations: linked below.

110

Klara Inc @klarainc.bsky.social · 25/09/2026

InnoDB writes 16K pages. A default ZFS dataset uses 128K records, so every page update becomes a read-modify-write. That is 8x amplification you get by not configuring anything. One command fixes new writes: zfs set recordsize=16K tank/mysql. More ZFS fixes linked below.

110

Klara Inc @klarainc.bsky.social · 24/09/2026

ZFS random IOPS scale with vdevs, not disks. One 12-disk RAIDZ2 has roughly the random I/O profile of a single disk. The same 12 disks as six mirror pairs have six vdevs pulling I/O. Layout is a day-one decision; fixing it later means rebuilding. Full article linked below.

100

Klara Inc @klarainc.bsky.social · 23/09/2026

ashift is set when a ZFS vdev is created and can never be changed. A 512e drive that lied about its sector size means write amplification for the life of the pool. Check yours: zdb -C tank | grep ashift. The biggest ZFS misconfigurations and how to fix them: linked below.

FreeBSD 13 is EoL. 15.0-RELEASE follows on September 30. Your upgrade window does not have to be upstream’s. Keep the branch you run patched while you plan the move. na3.hubs.ly/y0CD_V0 #FreeBSD

020

Klara Inc @klarainc.bsky.social · 21/09/2026

Quarterly maintenance windows: 4 chances a year to touch every machine. A FreeBSD branch ships 2 minors a year, each supported only 3 months past its successor. Miss one window and part of the fleet slides out of support. The full cadence math: article linked below.

Klara Inc @klarainc.bsky.social · 18/09/2026

Upgrade one server and a 99% success rate sounds great. Run it across 200 machines and it means two expected failures every cycle. At scale, upgrade failures are not a risk. They are a line item. The hidden costs of upgrading FreeBSD in production: article linked below.

110

Klara Inc @klarainc.bsky.social · 17/09/2026

Best practice for FreeBSD upgrades: bectl create pre-15.1 before you touch anything. A ZFS boot environment makes rollback a reboot, not a restore-from-backup. More practices that lower the production upgrade bill: article linked below.

FreeBSD support windows are short by enterprise standards. LTS by Klara extends security patching past project EoL: advisories triaged against your installed base, fixes backported, delivered via pkg. Upgrade on your schedule. Details linked below.

The FreeBSD download is free. The maintenance window is not. ITIC’s 2024 survey puts an hour of downtime above $300k for 90% of mid-size and large enterprises, and 41% say $1M to $5M+. What a production upgrade really costs, and how to lower it: article in the comments.

Leaving FreeBSD 13 is bigger than a version bump: OpenSSL 1.1.1 to 3.0, every package rebuilt, portsnap and mergemaster gone, 32-bit platforms retired in 15. And with 15.1 current, it is a two-major-version jump. What that means for real fleets: article in the comments.

FreeBSD 13 reached end of life on April 30, 2026. Five years, six minor releases, then the advisories stopped. Every CVE since then is permanent exposure for 13.x systems. Why so many fleets are still there, and what the way out looks like: article in the comments.
