Why Did Intel Sell its SSD Business?

Intel recently sold its NAND flash business, which was mainly producing SSDs, to SK hynix, a Korean competitor.  Some people have asked the SSD Guy why did Intel do this? The company had highly-regarded products that could command top prices.  Since Intel’s NAND flash fab is in Dalian, China, one person even asked if the divestiture could have been in response to the US-China trade war.

A better question is: “Why did Intel Continue reading “Why Did Intel Sell its SSD Business?”

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”

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?

Micron’s New XPoint SSD Finally Arrives

Micron X100 3D XPoint SSDAt its October Insight Conference Micron Technology finally revealed its 3D XPoint SSD, dubbed the X100.

While the company didn’t disclose too much about the device, it did brag about its speed, claiming that the X100 is the world’s fastest SSD, running three times faster than the fastest NAND flash SSDs and almost three times the speed of other XPoint SSDs.  The product is said to Continue reading “Micron’s New XPoint SSD Finally Arrives”

The Memory/Storage Hierarchy

Memory/Storage ThumbnailIt recently dawned on me that one of the charts that I most frequently use in my presentations has never been explained in The SSD Guy blog.  This is a serious oversight that I will correct with this post.

The Memory/Storage Hierarchy (also called the Storage/Memory Hierarchy, depending on your perspective) is a very simply way to Continue reading “The Memory/Storage Hierarchy”

Podcast: Flash Memory Summit 2019

GreybeardsThose of you who enjoy listening to podcasts may want to hear Ray Lucchesi (Silverton Consulting) and Keith Townsend (The CTO Advisor) interview The SSD Guy for their series “Greybeards on Storage.”

This interview is the series’ 86th episode covering the world of storage.  These guys do a fantastic job of probing this industry with great enthusiasm and insight.

This episode is a 40-minute compendium of the sights and goings-on at the August 2019 Flash Memory Summit along with observations on the industry in general.  It’s not strictly structured, and not strictly serious, but just three industry insiders having a lot of fun sharing their observations.

Some of the broad range of subjects that Continue reading “Podcast: Flash Memory Summit 2019”

Start-Up Fadu Launches New SSD Controller

Fadu, a startup out of Korea, made a big  splash at the Flash Memory Summit to announce its new NVMe SSD controllers that don’t compromise speed to achieve low-power operation.

The company’s products are focused on quality of service (QOS) in enterprise-style 24/7 workloads with the aim of enabling the transition to NVMe in Enterprise and Hyperscale data centers, the fastest-growing segments in the SSD market.  Some readers may recall that Fadu won the 2018 FMS Best-of-Show award in the “Most Innovative Flash Memory Technology” category for an earlier generation of products.

The company’s founding team comes from Samsung and Hynix with a CEO (Jihyo Lee) from Bain Capital.  Lee gave a keynote address at the Flash Memory Summit simply titled: “Enterprise SSD: The Future”

The new SSD controller, Annapurna, is a Continue reading “Start-Up Fadu Launches New SSD Controller”

Intel’s Optane: Two Confusing Modes. Part 4) Comparing the Modes

Exploding HeadThis post completes The SSD Guy’s four-part series to help explain Intel’s two recently-announced modes of accessing its Optane DIMM, formally known as the “Intel Optane DC Persistent Memory.”

Comparing the Modes

In the second and third parts of this series we discussed Intel’s Memory Mode and the company’s App Direct Mode.  This final part aims to compare the two: When would you use one and when the other?

There’s really no simple answer.  As with all benchmarks, certain applications will perform better with one mode than with another, while other applications will behave the opposite way.  Adding to the problem is the fact that App Direct Mode actually supports not one but four different access methods, which will be further explained below.  As a rule of thumb performance for large serial accesses might be Continue reading “Intel’s Optane: Two Confusing Modes.

Failure is Not an Option — It’s a Requirement!

I was recently reminded of a presentation made by GoDaddy way back in the 2013 Flash Memory Summit in which I first heard the statement: “Failure is not an option — it is a requirement!”  That’s certainly something that got my attention!  It just sounded wrong.

In fact, this expression was used to describe a very pragmatic approach the company’s storage team had devised to determine the exact maximum load that could be supported by any piece of its storage system.

This is key, since, at the time, GoDaddy claimed to be the world’s largest web hosting service with 11 million users, 54 million domains registered, over 5 million hosting accounts, with a 99.9% uptime guarantee (although the internal goal was 99.999% – five nines!)

The presenters outlined four stages of how validation processes had Continue reading “Failure is Not an Option — It’s a Requirement!”
