Storage
Cloudera struck lucky in getting a $5M A-round away just before the markets shut down in response to the collapse of the global financial system. Backed by Accel Partners and more recently Greylock Partners they are making a bet that Hadoop with a smart scale out approach to managing large amounts of data is a [...]
Continue ReadingRecently I spoke to David Emery a friend and colleague from my time at Coopers & Lybrand. He is now working on a major social media initiative for a global mobile telco. I was interested in David’s perspective as he has been working on a set of solutions to process log files at enormous scale. [...]
Continue ReadingA while back I met Kathrin Winkler, Chief Sustainability Officer at EMC. She was delivering a briefing about EMC’s Corporate Social Responsibility (CSR) activities to a group of industry analysts. Most CSR briefings are as dull as ditchwater and devoid of anything remotely innovative or challenging. CSR is for some just going through the motions [...]

I only just caught the end of the era at University where I learned to program in FORTRAN coding one punched card at a time. Once the stack of cards was complete, I delivered it to the computer operator for [...]
Continue ReadingIf you have been following the storage business for a while, you will have noticed a few changes:
Introduction of Flash Memory components as Solid State Disks
Serial ATA (SATA) disks becoming popular and growing in capacity (2TB soon)
There are lots of other disk technologies around like Fibre Channel and SAS but SSD and SATA are getting [...]
Continue ReadingBoth Seagate and Western Digital announced Q2 results last week perhaps signalling a return of confidence in the disk drive channel. Component manufacturers in the enterprise IT channel are an interesting bellwether of market confidence as orders need to be placed in advance of shipments of finished goods. There is a significant delay in revenue [...]

Storage Administrator: So do you want NAS or Block storage?
Application Developer: Is there a Java object library for that stuff, what did you call it nasty blocks?
Storage Administrator: (mumbles) stupid code monkey… Who knows – thats your job [...]
The Hot Aisle ran a poll recently asking you all about Cloud Storage and we got some very interesting results from over 5600 respondents:
We asked the question – Does Cloud Storage have to be delivered as an Object Store?
Here are my observations:-
A surprising number of folks don’t know what Cloud Storage is!
Most people thing that [...]
I visited IP Expo at Earls Court today and had a look around and concluded that everyone is on message about the cloud. If vendor push gets a technology going then cloud is moving at the speed of light.
I mostly went to interview VirtualGeek, Chad Sakac VP, VMware Technology Alliance at EMC who was hot [...]
This week we have had two announcements about extreme (and I mean extreme) high performance storage arrays that follow the same basic approach. What they have in common is that they both use solid state (Flash) memory with a twist.
Oracle announces the Exadata Storage Server v2 their new Sun built OLTP Database machine and makes [...]
The Exadata uses Flash, lots of Flash and it uses Infiniband, not Fiber Channel, Ethernet or FCoE. Exadata uses PCI Flash memory modules not Solid State Disks. Actually it is not a general purpose storage controller and it doesn’t support non Oracle Database workload. It is designed from the outset to host Oracle Databases and [...]
Continue ReadingI just picked up a neat blog post by Martin Glassborow (@storagebod) discussing a double disk failure in a RAID 5 array which (apparently) caused lost data.
RAID is Redundant Array of Independent Disks and the number refers to the type of protection offered. RAID 5 means that there is an extra disks in the group [...]
The Storage Area Network (SAN) is now a key component of most reasonably sized IT Infrastructures. The SAN we rely on today evolved from very humble beginnings into a mission critical Enterprise IT component. The first SANs were introduced to handle small numbers of enterprise scale systems (zSeries and iSeries computers from IBM) being connected [...]
Continue ReadingI received a very thought provoking article about the relative merits of FCoE and Fibre Channel storage networks from Christian Illmer, Senior Director Application and Solution Management Enterprise, ADVA Optical Networking – 8G FC versus FCoE – distinguishing myth from reality.
I publish the article here in it’s entirety and add a bit of analysis myself [...]
I am giving the Cloud Summit Keynote at Virtualization World (co-located with SNW Europe in Frankfurt on the 27th and 28th October), my subject will be a familiar theme to readers of the hot aisle – The Data Center of the Future – M&E plant to Cloud. I am also chairing a couple of panels, [...]

My friend Dan Gatti who runs worldwide marketing at Verari sent me this picture showing the inside of a FOREST Data Center Scale computer rigged out with 26 Petabytes of disk storage. Verari are market leaders in Data Center Scale compute platforms and have shipped significantly more of these storage and compute units than other vendors [...]
