Avoiding the Storage Performance Bathtub Curve
We’re probably all familiar with the concept of the HDD or SSD reliability bathtub curve (figure 1). This shows how over the lifetime of a drive, failures typically follow a pattern where failure rate increases over time to a steady state, then increases again as the device wears out. But have you considered the idea… Read more »

The Britpop Battle of Rubrik and Cohesity
Were you a Blur or Oasis fan? Perhaps you were on the side of Jarvis Cocker and preferred Pulp. Whatever your choice, the Britpop wars of the 1990s were memorable for building hype around the UK music industry and the idea of Cool Britannia. In lots of ways, the evolution of the data protection industry… Read more »

NVMe over Fabrics – Caveat Emptor?
For the past 20 years, Fibre Channel has been the dominant enterprise data centre storage networking technology. By this, I mean traditional Fibre Channel, not variants that work over IP or use Converged Ethernet (more on that in a moment). It’s true that other protocols exist. Smaller organisations have typically used iSCSI, because of the… Read more »

IDC 1Q2018 Data Shows a Rebound for Storage Hardware Sales
The latest IDC Storage Tracker numbers are out and in the spirit of recent analysis, I’ve put the numbers into my tracking spreadsheet. The figures represent data for Q1, which now has 12 years’ worth of coverage. With around 42% growth in the general storage hardware figures and 20% in external storage sales, the numbers… 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 Race towards End-to-End NVMe in the Data Centre
The next greatest thing in storage hardware is the move to NVMe. This is occurring in two ways – conversion of internal designs within shared storage platforms to use NVMe at the “back-end”, and front-end (or host connectivity) using NVMe over Fabrics in some form. Vendors are starting to use the term “end-to-end” NVMe as… Read more »

Micron ushers in the era of QLC SSDs
To date we’ve only seen QLC NAND storage in the consumer SD card format, however, that’s set to change as Micron announces the first QLC SATA SSD for the data centre. The Micron 5210 ION SSD will deliver up to 7.68TB of capacity in a standard 2.5″, 7mm form factor. But there’s a catch –… Read more »

Conflating Data Protection and Data Mobility
Sitting on the sidelines, I’ve been watching some of the traffic and communications coming from VeeamON this week. Chris Mellor just posted a quick article summing up the ambitions of Veeam as a company. It struck me that we continue to conflate the idea of data protection and data mobility. To me, these are two… Read more »

NetApp Extends Cloud Volumes to GCP
Following their introduction on Microsoft Azure last year, native NetApp Cloud Volumes are to be made available through Google Cloud Platform. NetApp now offers Cloud Volumes in some form on the three major (Western) cloud providers, AWS, Azure and GCP. How should we view this, especially in respect of how cloud services are evolving? Maturity… Read more »
