Making All-Flash 3D TLC SSD Arrays Enterprise Ready


Good post by George Crump (thank you)

All-Flash Array Vendors are now releasing systems with 3D TLC SSDs. They claim that they have reached price parity, without data efficiency, to mainstream data center hard disk arrays. 3D TLC NAND does bring the price per GB of flash storage down considerably, but it does carry the risk of device failure and data loss. Understanding how a vendor mitigates that risk is critical to vendor selection.

Netlist Readies PCIe Based High Performance NVRAM

Post by George Crump (thank you)

The ever-increasing density of virtual infrastructures, and the need to scale databases larger than ever, is creating an ongoing need for faster storage. And while flash has become the “go to” performance option, there are environments that still need more. Nonvolatile DRAM is the heir apparent, but it often requires customized motherboards to implement, for which widespread availability could be years away. Netlist, pioneer of NVRAM, has introduced a product that is viable for most data centers right now: the EXPRESSvault EV3.

New Generation Storage Arrays

Post by Harsha Hosur (thank you)

I recently read a blog by Josh Odgers about the the requirement for hardware support specifically availability of the storage controllers or lack thereof (link:×7-4-hour-onsite-should-no-longer-be-required/). So I wanted to share my experience with storage controller availability and how modern storage systems provide availability as well as performance. I have used examples of system I have worked on extensively (XtremIO) and also other vendor technology that I read up on (EMC VMAX and Solidfire).

Hyper-Convergence And All Flash On The Way

Post by Howard Marks (thank you)

Will a combination of the two shiniest technologies in the storage business make a match like champagne and caviar, or will it create a system looking more like a chocolate-covered pickle?

A few of my fellow storage pundits have lately taken to predicting the arrival of the all-flash hyper-converged system.

At VMworld this year, Micron was demonstrating an all-flash VSAN cluster. The company crammed a pair of Dell R610 servers with 12 core processors, 768 GB of RAM and two tiers of SSDs, a pair of 1.4 TB P420 PCIe cards to hold VSAN’s read and write caches, and 10 960 GB M500s as the “bulk storage” tier. And while some technologies —  like flash and data deduplication — go together like champagne and caviar, an all-flash hyper-converged system looks more like a chocolate-covered pickle to me.

Top five stupid storage technology ideas

Good post by Jon Toigo (thank you)

Talk show host David Letterman may be well on the road to retirement, but we can still credit (blame?) him for all those idiotic Top 10 articles and presentations that seem to dominate the field of technology journalism these days.

From the look of things, the solution to any IT problem can be neatly distilled into 10 convenient observations or fixes — fewer if the publication has word count constraints.

Server-side Caching is really hot !

Post by Enrico Signoretti (thank you)

Almost a year ago I wrote a piece about server-side caching, wondering if it was a mere feature or something more. After this VMworld it is pretty clear that server-side caching is quickly maturing and is a really interesting area to look at, not just for what it does today but for what we have to expect tomorrow… especially from the virtualization perspective.

My roadmap for the VNXe series

Post by Justin Paul (thank you)

Every now and then I get a little arrogant and do a post like this where I take my best stab at what I would do if I were the product manager/Chief Architect of a particular product. Since I’ve worked with the VNXe’s since they first hit the market, and since I’m working on other articles while I have one of the new VNXe3200′s I thought what the hell, lets do a fictional roadmap of the VNXe series, as well as EMC storage in general.

RAM and Flash are the key for effective general purpose Scale-out Infrastructures

Good Post by Enrico Signoretti (thank you)

A couple of weeks ago, during Storage Field Day 5, I had the opportunity to learn more about interesting “new” technologies set to have a tremendous impact on future infrastructures development: Flash and RAM.

I’m not kidding! It could sound weird but it’s not about the technology itself rather how it can now be used to build next generation infrastructures.
