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...)
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...)
I’ve updated my install cookbooks page to include a new cookbook for installation of Oracle 18.104.22.168 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)
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...)
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...)
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...)
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...)
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!
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...)
- Hybrid Flash Arrays
- SSD-based All Flash Arrays
- Ground-Up All Flash Arrays (which from here on I’ll refer to as Custom Flash Module arrays or CFM arrays)
I’ve already blown metaphorical raspberries at the hybrid approach, so now it’s time to cover the other two.
