Why Deterministic Storage Performance is Important

In the days of spinning media, I/O performance was anything but consistent.  When mechanical head movement is involved, response time can vary enormously.  Actually, the variation of I/O isn’t just to do with mechanics as we will discuss in a moment.  However, inconsistent I/O response time is a problem for applications and as tolerances reduce,… 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 »

Making The Case for SATA SSDs

Update:  Looks like Samsung released new versions of their 800 Series, also focused on increased endurance (link) although products are a mix of MLC and TLC. Micron has recently announced a refresh to their 5100 SATA SSD series with the release of the 5200 series using 64-layer 3D-NAND technology.  As discussed on our most recent… Read more »

Flash Diversity: High Capacity Drives from Nimbus and Micron

The desire to provide cheaper and greater capacity storage devices knows no bounds and has been a focus of the industry for the last 60 years.  Following on from Seagate’s 60TB “concept” flash drive, we now have two vendors selling 50TB OEM flash drives from Nimbus Data.  Let’s put that into context – the largest… Read more »

Unreliable Disks for Better Scale-out Storage

Recently I was asked to review a document that used as a reference a piece of work from Google which talked about the need to relax the resiliency levels of hard drives and SSDs.  The premise is interesting.  Hyper-scalers claim they could do a better job in managing performance and availability if the HDDs they… Read more »

Seagate Ups The Ante with 60TB SSD

Hot on the heels of Samsung’s 15TB SSD, Seagate has announced their own hyper-capacity drive, an (as yet) unnamed 60TB SAS solid state disk.  The new product was announced at the recent Flash Memory Summit in Santa Clara, California, USA.  So is 60TB setting a new standard?  Is it a practical device for every day… Read more »

Are DataCore’s SPC Benchmarks Unfair?

DataCore has been active over recent months with benchmarks based on their new SANsymphony Parallel Server offering.  The most recent of these claims 5.1 million SPC-1 IOPS at $0.08/SPC-1 IOPS and 0.32 millisecond response time.  Other vendors are crying foul on these results, claiming they don’t represent a true test because all of the data… Read more »

The Rise of Ultra-Fast Storage Appliances

Updated 16 October 2017 with new companies. The early days of shared storage were focused around fixing some of the problems experienced with having multiple disk drives in every server, namely – availability, resiliency, shared access and efficiency.  Shared storage arrays resolved many of these issues by providing centralised shared, optimised and managed storage resources….
