Monthly Check October 2026: TrueNAS 27, Proxmox Plugin Early Adopter and a New DATAZONE Vehicle

Compared with a packed September, October 2026 was a month with fewer but heavier topics. Two iXsystems decisions noticeably reshaped 2027 storage planning, the official TrueNAS storage plugin for Proxmox VE has left the preview phase for good, and a second DATAZONE-branded Tesla Model Y arrived at the office. Alongside, two backup topics kept coming up in customer conversations: honest cloud TCO numbers and immutable storage as a response to the ransomware wave.

Rather than dumping a news feed, we summarise what actually mattered in customer talks. Each section links the matching October article for anyone who wants to go deeper. The month closes with an outlook on November, the usual autumn topics in the server room, and an FAQ covering the recurring questions we received over the past four weeks.

TrueNAS 27 Instead of 26: The iXsystems Rename and What It Means for Planning

The most visible news of the month came out of San Jose on 6 October: iXsystems renamed the successor of 25.10 Goldeye to TrueNAS 27 right before the December release. The reasoning is pragmatic — the version number should reflect the primary year of use, and TrueNAS 27 will mostly run in production during 2027. The familiar YY.MM scheme ends with this move; dot releases will now be numbered sequentially.

For day-to-day planning, little changes. GA is still scheduled for early December 2026, the technical base of Linux kernel 6.18 plus OpenZFS 2.4 stays, and the upgrade path from 25.10 Goldeye runs through the usual beta-RC cascade. What changes is the external communication: anyone who had written “TrueNAS 26” into a quote or project plan needs to update that. The full breakdown including upgrade-path guidance is in our article TrueNAS 27 instead of 26: iXsystems renames the December release.

An important point for customers planning right now: TrueNAS 25.10 Goldeye remains the stable release at least until mid-2027. Projects started today should ship on 25.10 and schedule the move to TrueNAS 27 for Q1 or Q2 2027 — not for the week after GA. The TrueNAS configurator remains unaffected on the hardware side; the rename does not touch the configurator math.

What the Rename Actually Triggered in Customer Meetings

In two concrete October projects we had to explain the versioning directly:

• A mid-market customer with a storage refresh in spring 2027 already had “TrueNAS 26” in the budget proposal for the leadership team. We updated the document and clarified that nothing changes technically.
• A customer running a 25.10 rollout worried that the rename signalled a shorter Goldeye support window. That is not the case — 25.10 stays on its known lifecycle.

Proxmox Plugin Early Adopter: Official Rollout and Our Partner Contribution

The second big signal was already in the starting blocks in mid-September and became tangible in October: the official TrueNAS storage plugin for Proxmox VE has left the preview phase. With signed APT repositories for Bookworm and Trixie, a cluster-aware installer and multi-tenancy support, the plugin has reached early-adopter status. The admin-side take is in TrueNAS Proxmox plugin leaves preview.

As an authorised iXsystems partner, we have been running the plugin in our lab in production mode since early October. Four observations from version 2.1.17+deb1 on PVE 9.2.11 with TrueNAS SCALE 25.10.6 went back to iXsystems and are documented publicly so other early adopters benefit. The partner-contribution article with concrete workarounds is at TrueNAS Proxmox plugin 25.10.6: four observations from our lab.

What we kept explaining to customers in October:

1. Early adopter is not production-ready for everyone. For strict production environments without a lab buffer, we still recommend waiting for the stabilised release.
2. For partners and committed admins, now is the time to join. The more feedback reaches iXsystems, the faster the plugin hardens.
3. The plugin does not replace a sound network design. NVMe-over-TCP and iSCSI still need dedicated storage VLANs and redundant paths.

If you plan a plugin introduction in your own environment and want partner support, our virtualisation consulting or TrueNAS support is the right entry point.

Storage TCO October 2026: Cloud vs TrueNAS, Honestly Calculated

On 6 October we published a calculation that keeps surfacing in customer talks: what does storage really cost over five years — hyperscaler object storage versus your own TrueNAS? The article What does storage really cost? Cloud vs TrueNAS over 5 years puts the numbers on the table. Core message: cloud storage looks cheap in year one but flips the math from year two or three onwards, as soon as egress traffic, API calls and continuous snapshot operations enter the picture.

The article deliberately avoids fixed end prices. Hardware prices for SSDs, HDDs and PSUs shift monthly in 2026, and hyperscalers adjust their egress models regularly. What stays reliable is the five-year TCO structure and the threshold at which on-premise storage pays off. For most of our mid-market customers that threshold sits well below what the hyperscaler pricing calculator initially suggests.

Two points we explained especially often in October:

• Egress is the silent multiplier. Pushing backups into object storage means paying for the restore. A real disaster restore via hyperscaler egress can easily cost more than half a year of storage subscription.
• Continuous operation beats one-off cost. The cloud bill runs linearly; the on-premise bill gets cheaper every operating year — until the next refresh.

For an individualised calculation in your environment, our storage consulting is the starting point.

Immutable Backups and Cloud Resilience: Two October Articles, One Topic

In parallel with the TCO debate, backup resilience was the second main theme of the month. Two articles that belong together:

The post TrueNAS as an immutable backup target for Veeam and Proxmox describes how to set up TrueNAS as an S3-compatible object-lock target — on-premise, without cloud egress and with cleanly defined retention. Veeam admins know the pattern from the hardened-repository world; the TrueNAS variant via object lock works conceptually the same way and is the more pragmatic path for many SMBs.

The complementary article Cloud is not a backup: on-premise with TrueNAS as a resilient tier puts the discussion into the broader resilience context. Even AWS, after the destroyed data centre in Northern Virginia, pointed customers back to their own backups — a clear signal that the cloud is resilient but not invulnerable. A local ZFS tier with snapshot replication, air-gap and immutability remains the most stable anchor in any backup strategy.

What we repeated to customers in October: immutable backup is not a marketing label. What matters is that retention cannot be shortened unilaterally by the backup admin and that any deletion workflow requires a second approval step. Everything else is just an awkward snapshot management.

New Tesla Model Y: The Everyday Moment of October

Between the software topics, October brought a very practical moment that fits the DATAZONE outside image: our second Tesla Model Y with DATAZONE wrap is on the road. The predecessor returned as a leasing hand-back after four years without a single unplanned workshop visit. We repeated the decision on purpose and explain why in the article New Tesla Model Y in the DATAZONE fleet.

Short version: price-performance fits our service routine with customer trips across Bavaria and beyond, the range is comfortable without nervous planning, and daily reliability is quietly dependable — which is exactly what a company car should deliver. The electric drivetrain fits credibly into the sustainability line we already run in the server room.

What Else October Brought: Winter Check, SDN and SMB Security

Beyond the five main topics, several focused articles landed in October:

• Winter server-room check: the clock change in October is the quiet trigger for many admins to walk through the rack. Ventilation, temperature alarms and UPS test runs are listed in Winter server-room check.
• Proxmox SDN with VXLAN: for customers with two to four sites, software-defined networking in Proxmox is becoming a realistic option. Field notes from an October project are in Proxmox SDN and VXLAN overlay.
• TrueNAS SMB protocol and AES: anyone running SMB shares in mixed Windows environments should know the current encryption defaults. The article TrueNAS SMB protocol security with AES lays out the relevant switches.
• TrueNAS Mini R for remote work: not every branch office needs a rack. TrueNAS Mini R for home office and remote shows a compact variant for branch and home-office servers.

What the October News Means for Your Server Room

If we compress the month into three concrete recommendations:

1. Plan 2027 TrueNAS projects now, but ship on 25.10 Goldeye and schedule the move to TrueNAS 27 for Q2 2027 — not the GA week in December.
2. Evaluate the Proxmox plugin integration, but pick the production timing deliberately. Early adopter means co-shaping, not blind migration.
3. Treat backup resilience as a standard question, not a project. Immutable on-premise and a clean egress calculation belong in every 2027 storage strategy.

Outlook November 2026

Three focus areas emerge for November:

• TrueNAS 27 RC cascade: between RC.1 and GA we expect one or two more release candidates. For admins with a test environment, this is the phase where breaking changes and driver topics become visible.
• 2027 budget rounds: for many mid-market customers, concrete investment planning starts in November. Storage refresh, hypervisor strategy and cyber insurance show up almost everywhere.
• NIS2 follow-ups: the autumn audit wave continues. Gaps uncovered in October usually need to be closed by mid-November.

Alongside, we are watching the OPNsense 26.10 window and the expected OpenZFS dot-release cadence. Further partner feedback on the Proxmox plugin follows as soon as we have robust new observations from the lab.

FAQ on the October 2026 Monthly Check

Is TrueNAS 27 production-ready yet?

No. RC.1 has been available since 6 October, GA is planned for early December 2026. For production environments, TrueNAS 25.10 Goldeye remains the right choice until then. We typically schedule customer upgrades to TrueNAS 27 for Q1 or Q2 2027, not for the GA week.

Should I run the official Proxmox TrueNAS plugin already?

For test environments and committed admins with partner backing: yes. For strict production operations without buffer, we recommend waiting for the stabilised release. The early-adopter phase is meant for feedback and co-shaping, not for blind migrations.

Why no fixed prices in the monthly check?

Because hardware prices fluctuate monthly in 2026 and hyperscalers adjust their models regularly. Fixed end prices without a date are misleading. We work with price ranges in the blog and with individualised quotes for concrete projects — anything else would be dishonest.

Are TrueNAS M50 or M60 still options?

No, both models are end-of-life and are no longer recommended for new purchases. For current enterprise projects we look at the current M30 and M40 and the R-Series. The TrueNAS configurator does the reliable math.

How does a partnership with iXsystems work in practice?

As an authorised iXsystems partner we have a direct line to the product and engineering teams. Our role is constructive practical feedback — not vendor criticism. The Proxmox plugin lab work in October is a typical example: we document observations, release workarounds publicly and feed the findings back to iXsystems at the same time.

What should I plan concretely for November 2026?

Three points, honestly prioritised: first, investment planning for 2027 with a focus on storage and hypervisor; second, a maintenance window for the current OPNsense and Proxmox patch levels; third, a clean second review of all backup jobs regarding immutability. We are happy to accompany customers on all three — get in touch.
