NVMe Polishes Its Specs, Brings Virtualization to Locally Attached SSDs

The latest NVMe specifications add SSD-level virtualization that can simplify live VM migration by preserving storage identities across servers. The updates also introduce support for post-quantum cryptography, controller-based rate limiting, voltage monitoring, and factory-reset capabilities. The Register reports: Announced by the NVM Express consortium, all 11 of the suite of NVMe specs have been updated with new features and engineering change notices. These represent the next step in the evolution of the standard, it says, which was created as a protocol to support storage devices connected to a system's PCIe bus. Perhaps the most significant new capability is PCIe Exported NVM Subsystem Migration. This extends existing NVMe virtualization to locally-attached PCIe SSDs. It does this by abstracting the physical drives into host-defined virtualized NVM subsystems, to allow for virtual machine (VM) mobility without storage reconfiguration. When a VM moves from one server to another, its storage also needs to move with it in a way that's non-disruptive to any applications running in that VM. "With NVM Subsystem Migration, NVMe SSDs can present exported NVM subsystems that hide the complexity of the underlying hardware," says Mike Allison, a senior director at SSD maker Samsung and NVM Express board member. "Instead of interacting with physical controllers and namespaces, the host only sees exported controllers and namespaces. This creates a clean separation between what the VM sees and what's happening under the hood," Allison explains on an NVM Express blog. "One of the key innovations here is providing the host with control over exported identifiers. During migration, those identifiers can be carried over exactly from the source to the destination. That consistency is crucial: even if the underlying hardware uses different internal IDs, the VM sees no change and can pick up right where it left off with no storage reconfiguration required," he says. In effect, the NVMe layer now enables the virtual machine manager (VMM) to rely on virtualization built into the SSD. The flash drive itself exposes logical, virtualized storage constructs, offloading this complexity from the VMM. You can learn more about the updated NVMe specifications here.

Sandisk and SK Hynix Publish First Open High Bandwidth Flash Standard

BrianFagioli writes: Sandisk and SK hynix have published the first open technical specification for High Bandwidth Flash (HBF) through the Open Compute Project. HBF is designed to create a new memory tier between High Bandwidth Memory and traditional SSD storage, giving AI inference systems more near compute capacity without relying entirely on expensive HBM. The specification supports capacities up to 512GB using 8-high and 16-high NAND stacks, with bandwidth tiers ranging from about 0.4TB per second to 3.0TB per second. It also uses the UCIe chiplet interface, which could make HBF easier to integrate with CPUs, GPUs, and other accelerators. Google and Tenstorrent participated in the standardization effort, but commercial products and independent benchmarks are still missing.

macOS 28 Will Drop Support For Encrypted Mac OS Extended Volumes

Starting with macOS 28, Apple will no longer support encrypted Mac OS Extended, or HFS+, volumes. Users will need to decrypt them or reformat them as APFS to keep using them. 9to5Mac reports: In a new support document, Apple explains that starting with macOS 28, "the Mac OS Extended file system format will be supported only for volumes (disks and other storage devices) that aren't encrypted." In practice, this means users who currently rely on encrypted HFS+ external drives or other encrypted legacy Mac-formatted volumes will need to "either decrypt or reformat any encrypted Mac OS Extended volumes." Apple doesn't explain the reason for the change. Still, the move appears to be another step in Apple's transition to APFS, its file system with built-in encryption support, which replaced Mac OS Extended as the default Mac file system in macOS High Sierra. As a result of this change, Apple says that starting with macOS 26, Macs might notify users when they're using an encrypted Mac OS Extended disk that won't be compatible with macOS 28 or later. According to the support page, "the notification will identify the volume by name." However, Apple says users can manually confirm whether a volume is both using Mac OS Extended format and encrypted by following these steps [...]. Apple adds that "macOS 28 and later will continue to support unencrypted volumes that use Mac OS Extended format," and notes "Mac OS Extended is also known as HFS Plus (or HFS+)."

GitHub Thumbs Nose At Sony's Controversial End to Physical Media With Its Introduction of Repo CDs

GitHub is offering a limited run of 1,000 CD-ROM copies of public repositories as a pro-physical-media jab at Sony's plan to stop producing PlayStation game discs in 2028. Tom's Hardware reports: The coding and collaboration platform, owned by Microsoft, states that "In light of recent developments in physical media, GitHub is proud to announce that you can now obtain your public repo on CD-ROM." Moreover, it appeals to the human side of computing, adding the emotive line "Keep it. Lend it to friends. Pass it on to your children." It isn't April 1st, so thankfully this is no joke. However, if you check out the above-linked GitHub Your Code, On a CD offer page, it quickly becomes clear this is a very limited in time/scope stunt. "Order a burned CD of your own public GitHub repo. Yes, a real physical disc you can hold in your hands, no download required," begins the spiel. But this is a very limited run of 1,000 discs, with applications required between July 2 and July 6 (inclusive). Limit one per person, with availability varying between country/region. "Your code is physically yours, forever. Until you lose it, let's be real," says GitHub. At best, these CDs will be framed and put on a wall, some becoming collector's items or eBay money spinners (discs like 0001 or 0888 would be good ones, if they are numbered). Also, many will be lost or eventually/accidentally discarded, as GitHub seems to know. So this 'protest' is arguably 1,000 doses of expensively shipped e-waste.

Terabyte update 2026

HARDWARE By Will Fastie In last year’s Terabyte update, I mentioned chaotic pricing and the difficulty in stating future trends. This year, it’s far worse. To the extent I mentioned cause and effect, I was wrong. Tariffs bounced around and eventually settled down; they had little effect on the storage market. Inflation was a factor […]

Mac mini change

I saw headlines yesterday, such as β€œApple Removes $599 Mac mini, Raises Starting Price to $799.” The knee-jerk reaction to a headline like that is that Apple raised prices. It’s not true. There is a readjustment. True, a Mac mini priced at $599 is no longer available. The lowest-priced mini is now $200 more, at […]

Will’s NAS: Planning

ISSUE 23.18 β€’ 2026-05-04 HARDWARE By Will Fastie Somewhere in the AskWoody archives, you’ll find an article stating my ultimate goal β€” to reduce the number of PCs on my desk from four to one. Hah. That didn’t happen. I did manage to cut it down to two, though. Then I bought a Mac mini. […]

Will’s NAS: Build

HARDWARE By Will Fastie Physically putting the NAS together is easy. Setup takes some time. You’d think somewhere along the line I’d have deployed network-attached storage for someone, client or friend. This is the first time. It’s different from putting together a RAID solution for a business’s server or creating a mirror for my own […]

Will’s NAS: Deploy

HARDWARE By Will Fastie With the NAS now up and running with an accessible storage volume, it’s time to make it useful. What’s useful? As stated in the previous articles, I want the contents of my D: drive out of my daily driver, Obsidian. But I still want all that data to be easily accessible. […]
