Database Replication is Hard

I can only feel sympathy for the team at GitHub, after they suffered an outage recently, due to issues with database replication.  The problem was caused by a mere 43-second break in network connectivity.  We’ve all been there – keeping replicated data in sync is a thankless task and one that can be a nightmare… Read more »

Avoiding All-Flash Missing IOPS

We are living in a golden age of storage media, where new products come to market offering ever greater performance with lower latency than previous generations.  Today the hard drive and even early flash drives look positively archaic compared to modern NVMe drives built from 3D-XPoint, capable of delivering hundreds of thousands of IOPS and… Read more »

The Practicality of In-Situ Processing

On last week’s Storage Unpacked podcast, we talked to Chris Mellor about IoT.  He raised the subject of “in-situ processing” or basically taking compute to storage.  On the face of it, this seems like a good idea.  In fact, last year I talked to Enrico Signoretti, Head of Product Strategy at OpenIO about the company’s… Read more »

What Next for XtremIO?

The Dell EMC XtremIO team recently presented at Storage Field Day 14.  It was an opportunity to catch up on a technology I’ve been less than positive about over the years.  So has XtremIO X2 moved on?  What does the future look like for the all-flash platform? XtremIO Background XtremIO Inc was an Israeli start-up,… Read more »

Seagate Pre-announces Multi-Actuator Drives

When your technology is based on mechanical motion, it’s inevitable that at some point the laws of physics will get in the way.  This has been a problem for hard disk drives for some time.  Spin speeds never exceeded 15K RPM except in some test drives.  As a result, throughput has been limited by this… Read more »

Four Platforms When One Will Do?

One of the more interesting discussions from SFD14 was the review of the various mid-range platforms that Dell EMC now offers.  The merger of the two organisations brought Unity and VNX(e) from EMC, while SC (Compellent) and EqualLogic came from the Dell side.  Each platform has very different characteristics.  Unity and VNX(e) have heritage from… Read more »

That 100TB Drive Is Closer Than You Think

Another day goes by and we have another story about hard drive technology.  Yesterday, Western Digital held a media event (I wasn’t invited) to announce MAMR, the latest technology for improving hard drive density.  MAMR stands for Microwave Assisted Magnetic Recording and is a process to increase the stability of recording with very small grain… Read more »
