If you are planning on attending the UKOUG Tech16 event at the Birmingham ICC next week, I am presenting on the subject of flash storage at the following time:

Date: Monday 5th December
Time: 13:10 - 14:00
Title: Flash Storage for DBAs: You can't avoid it anymore
Track: Systems 1
Location: Hall6B

In this session I’ll be discussing why flash storage is something that DBAs need to understand. I will then bestow upon the audience key pieces (more...)

All Flash Arrays: Active/Active versus Active/Passive

running

I want you to imagine that you are about to run a race. You have your trainers on, your pre-race warm up is complete and you are at the start line. You look to your right… and see the guy next to you, the one with the bright orange trainers, is hopping up and down on one leg. He does have two legs – the other one is held up in the air – he’s just choosing to (more...)

All Flash Arrays: Controllers Are The New Bottleneck

bottleneck

Today’s storage array market contains a wild variation of products: block storage, file storage or object storage; direct attached, SANs or NAS systems; fibre-channel, iSCSI or Infiniband… Even the SAN section of the market is full of diversity: from legacy hard disk drive-based arrays through the transitory step of tiered disk+flash hybrid systems and on to modern All-Flash Arrays (AFAs).

If you were partial to the odd terrible pun, you might even say that it was a bewildering array of (more...)

New Installation Cookbook: Oracle Linux 6.7 with Oracle 11.2.0.4 RAC

cookbookI’ve updated my install cookbooks page to include a new cookbook for installation of Oracle 11.2.0.4 Real Application Clusters on Oracle Linux 6.7.

This is also the first one I’ve published since I left the employment of Violin Memory to work for Kaminario, so this install uses a Kaminario K2 All Flash Array. However, it applies very well to any Oracle RAC installation which uses relatively capable storage.

How the Next Generation of Flash Storage is Changing the Economics Of SaaS Businesses (Recorded Webinar)

SaaS Webinar

This week I had the opportunity to record a webinar on a subject very close to my heart, the Software-as-a-Service industry. From 2003 to 2007 I managed the production infrastructure for a global SaaS company through the transition from startup to acquisition (partly by Salesforce.com). At the time, SaaS was a relatively new phenomenon, predating any concept of “Cloud”, but the challenges we faced then are still very relevant today.

The company was run by charismatic (more...)

Understanding Flash: The Fall and Rise of Flash Memory

grave

This month sees the four year anniversary of some interesting events. Commonwealth countries around the world celebrated the Diamond Jubilee of Queen Elizabeth II. Whitney Houston was tragically found dead in a Beverly Hills hotel. The Caribbean was hit hard by sargassum seaweed invasion. And I made the decision to leave the comfort of Oracle databases and join the exciting new All-Flash Array industry.

Ok, I might have been stretching the use of the word “interesting” there. But for those with (more...)

Understanding Flash: What is 3D NAND?

grid-cube-3d

About 18 months ago I wrote a post describing the different types of NAND flash known as SLC, MLC and TLC. However, 18 months is a lifetime in the world of technology so now I need to clarify it based on the widespread adoption of a new type of NAND flash. Let me explain…

Recap: 2D Planar NAND

Until recently, most of the flash memory used for data storage was of a form known as 2D Planar NAND (more...)

All Flash Arrays: Hybrid Means Compromise

hybrid-car-engine

Sometimes the transition between two technologies is long and complicated. It may be that the original technology is so well established that it’s entrenched in people’s minds as simply “the way things are” – inertia, you might say. It could be that there is more than one form of the new technology to choose from, with smart customers holding back to wait and see which emerges as a stronger contender for their investment. Or it could just be (more...)

Postcards from Storageland: Pure Storage Cancels Christmas

christmas-angel

Ho ho ho folks. It’s nearly Christmas Day, 2016 and it most definitely is the season to be jolly. It’s also an exciting time in the All Flash Array industry with NetApp announcing its intended acquisition of Solidfire for a reported $870 million. Merry Christmas to everyone at Solidfire!

Unfortunately those sentiments weren’t shared by Pure Storage’s VP of Product, Matt Kixmoeller, who published a blog on the subject of the acquisition which seemed a little on (more...)

Why Kaminario?

K2-mountain

This summer I made the decision to leave my previous employer and join another vendor in the All Flash Array space – a company called Kaminario. A lot of people have been in touch to ask me about this, so I thought I’d answer the question here… Why Kaminario?

To answer the question, we first need to look at where the All Flash industry finds itself today…

The Path To Flash Adoption

We all know that disk-based storage has (more...)
