New Interest in Monster-SSDs

Ugly scary SSD with tentacles, frowning yellow eyes, and a shark-like mouth full of pointy teethWhile listening to the most recent quarterly earnings calls The SSD Guy learned that there’s suddenly a lot of interest in 60-100TB SSDs for the data center.  What I didn’t hear was a strong understanding of why that is happening, although four of the five the leading flash companies say that it is driven by AI.  (Kioxia hasn’t reported yet.) Some say these SSDs are being used for training applications, while others say Continue reading “New Interest in Monster-SSDs”

Generative SSDs Coming Soon

Memory hierarchy pyramid standing on its apex, with tape at the point on the bottom, and L1 cache on the widest part at the top. At the sides are arrows pointing from bottom to top marked "Increasing Cost" and "Increasing speed"Now that Generative AI has hit its stride, the industry is beginning to see new applications of this technology that have previously been out of reach.  One such application is the development of the Generative SSD by an Andorran company by the name of SSDystopia, who took the time to brief The SSD Guy about its development.

The Generative SSD comes to the market with a completely different approach to Continue reading “Generative SSDs Coming Soon”

It’s Official: WDC to Split into HDD & Flash Parts

During the company’s October 30 earnings call Western Digital CEO David Goeckeler started the conversation with the revelation that the company would be split into two, with a new flash-only company to be created in the process.  This plan, intended to increase the company’s shareholder value, was the outcome of a process triggered by activist shareholder Elliott in May 2022, which was the subject of a couple of Continue reading “It’s Official: WDC to Split into HDD & Flash Parts”

AI’s Feeding Frenzy Killed My Sites

Picture of hungry sharkSome of this blog’s kindly readers alerted me to an outage last week.  The Internet service provider that hosts both blogs (The SSD Guy and The Memory Guy) plus the Objective Analysis website explained that one of the blogs’ activity had suddenly increased to over 100 times what was budgeted, so all three sites were shut down in response.

Time for a speedy call to my website guru for help.  He and I guessed that the culprit was probably Continue reading “AI’s Feeding Frenzy Killed My Sites”

Whatever Happened to “Hero” SSDs?

Bodybuilder with the insides of an SSD superimposedIt seems not so long ago that there were frequent press releases, and showings at trade shows, of “Hero” SSDs.  These demonstration models (which weren’t always released as products) always had some unique and impressive attribute.  They may have had a higher capacity than any SSD known to humankind, or perhaps they had phenomenal endurance.  Some broke the IOPS barrier.

The SSD Guy doesn’t remember anyone Continue reading “Whatever Happened to “Hero” SSDs?”

Failures Plague SSDs

Pomander from Organic AuthorityOver the past year there has been a rash of SSD failures unmatched by any prior year.  This came to a head a month ago when Apple’s M1 Mac started to show undue SSD wear.  It seems that people trapped at home and working remotely have taken up new habits on their notebook PCs (most of which now use SSDs) and these habits are causing their SSDs to wear out faster than they have in other, more normal years.

The “Work from Home” phenomenon has not only caused Continue reading “Failures Plague SSDs”

High Availability in an m.2 Format

Photo of finger pusing on hinge in center of m.2 HA SSDThe m.2 SSD format has become wildly successful in the data center for use as a boot drive and even in SSD arrays.  The m.2 format supports either the SATA or the NVMe interface,  Something that has been missing, however, is a version of this format for high-availability (HA) systems.  These are mission-critical systems that cannot fail, no matter what.

Until today HA systems had to Continue reading “High Availability in an m.2 Format”

New Book Explains Persistent Memory Programming

Cover picture of Intel's Persistent Memory bookAt January’s SNIA Persistent Memory Summit Intel was promoting a book titled: Programming Persistent Memory.  This book, aimed at programmers, explains how to develop applications programs that take advantage of persistent memory (PM) to avoid slower persists to SSDs, and also shows how to use Intel’s Optane DIMMs to increase a system’s main memory size.

On the software side the book explains Continue reading “New Book Explains Persistent Memory Programming”

Does Persistent Memory Improve Performance? Ask Oracle!

A model-by-model timeline of Oracle's Exadata product introductions with key specifications.At last month’s SNIA Persistent Memory Summit Oracle presenter Jia Shi, Sr. Director of Exadata Development, shared some statistics on the Exadata system’s history over the past ten years.  (Click on the graphic to the left to see the timeline.)  The speaker highlighted the fact that the system’s I/O performance has grown from 0.05 million IOPS ten years ago to 16 million IOPS today, a 320X improvement!  Shi said that Continue reading “Does Persistent Memory Improve Performance?
