Storage Short Take #54

Short Take for the Short Take

It's an abbreviated one this time around, because of some intervening travel and a busier-than-usual few weeks.

As always, links were live at the time of publication.


Storage Media and Technology

Personally, when it comes to cars I am decidedly old-school. The increased "digitalization" of cars concerns me that we'll soon have extremely strict EULAs just to get your car out of your driveway. Having said that, electric cars, in particular, have radically changed the paradigm, especially when it comes to storage and memory.

I've reported quite a few times on DNA Data Storage technology recently (maybe it's being reported more, or maybe I'm just paying attention more, I'm not sure which). Here's another article that discusses how digital data stored as DNA can be manipulated. In other words, so you've encoded the data as DNA. Now what?

ZNS (Zoned Namespaces, not to be confused with the ZFS file system), is a way of writing sequentially to a NVMe device. Dave Landsman (NVMe Board Member) takes 10 minutes and explains what it's all about.

As it turns out, I'm about to pull the trigger on a new ZFS archiving box, and am looking for appropriate drives, and Anandtech has their thoughts on the Best Internal Hard Drives in time for the holiday season.

Storage Companies in the News

Samsung has begun mass production of 1Tb TLC VNAND. They claim this is the highest storage capacity to date, and is designed for PCIe 4.0 and 5.0 environments.

Synology has updated security issues with Samba and OpenSSL.

Industry Associations and Standards

For those of you who are truly in the weeds with NVMe, TP6011 ("Scalable Resource Management") has been ratified. Effectively this allows for a more dynamic allocation of NVM Subsystem resources, which is particularly useful in IaaS and multi-tenant environments. If you have the correct NVMe permissions, you can access the document here (login required).

Timothy Prickett Morgan - one of my favorite trade writers - has a really interesting article on Mashing Up CXL and OpenCAPI. Now, it's mostly a product examination, but like everything with TPM you get more than just a pitch. You get a lot of insight as to how and why things work together.

Webinars, Blogs, and Conferences

The Compute Express Link (CXL) group has written a blog on CXL Fabric Management. This is a CXL 2.0 feature that has been expanded in 3.0, but it's good to get these basics before diving into what it's evolving into.

SNIA has released it's Q&A for it's Programming Frameworks webinar (xPU, GPU, DPUs, etc.)

If you're curious about CXL and Memory Semantics (and have never heard of SDXI - Smart Data Accelerator Interface), you'll definitely want to sign up for this webinar.

For those readers in the right regions of India, you may be interested in the SNIA India T/E/N Storage meetup coming up at the end of November.

ArchitectingIT has an interesting blog on Data Security and Data Protection (no, they're not the same thing - but they make a compelling argument to think of it in those terms).

If you read nothing else from this Short Take, read this. Chin-Fah Heoh breaks down the intersection of societal and cultural issues and the usage of data. He covers China's social credit system, the Indian Caste System, and AI, among others. His point is en pointe: the fox has been in the hen house for a while, and isn't going to go away as long as we refuse to acknowledge its existence.

Bonus Round

The inimitable Jonathan Winters.
