NVM Trends: Phase Change Memory

In the previous post, we learned how 3D NAND increased the areal density of Flash memory by employing geometrical, structural and material based innovations. As a result, it is 10x denser and 1000x faster than traditional NAND. However, it is uncertain if we can...

Non Volatile Memory Trends: 3D NAND

This is the second post in a series on Non-Volatile Memory Trends. In the previous post, we prepared a foundation by explaining the basics of Non-Volatile Memory and asked an important question: will Moore’s law continue to hold true for Flash Memory areal densities...

Non-Volatile Memory Trends: Introduction

Storage technology is a subject that is very close to my heart. I discussed Hard Disk Trends about a year ago and was fascinated by what I learned in my survey. This time, I’d like to share what I am learning about Non-Volatile Memory (NVM).  This is the first in a...

Decoupling storage capacity from performance

ACME Widgets has a storage performance problem ACME Widget’s data center setup (2 EMC arrays – 800 x 24 10K SAS per array – RAID 6 – 600 GB Fast Cache per array) gives them 16K IOPS. But their requirements are rapidly growing and ACME’s sys admin is...

Does your data center really need an All-Flash array?

Most data centers that use spindle based storage suffer from performance problems. Replacing existing storage technology with All-Flash arrays is an expensive and disruptive proposition. It requires data center’s to sacrifice existing investments in storage...
