EMC Unity or VNX3? What’s in a Name?

The big announcement at EMC World this week has been VNX3 or EMC Unity as we now have to call it.  The EMC Marketing Reality Distortion Field is in full effect, with EMC at pains to claim that Unity is a brand new product “designed from the ground up”, yet appears to be significantly based on… Read more »

IBM Reuses Existing Tech in Latest FlashSystem Release

This week IBM announced three new flash products, two of which are based on existing technology.  Mainframe/Power customers got the all-flash DS8888, with the A9000 and A9000R models covering the rest of the market.  What’s interesting about these latter two products is that they are based on Spectrum Accelerate, otherwise known as the software behind… Read more »

The Four Stages of All-Flash Storage

This week has seen yet more stories and announcements on all-flash storage.  IBM released new FlashSystem products based on XIV and an all-flash version of their mainframe/enterprise platform, the DS8888.  I had another briefing from Violin (although that didn’t reveal anything new) and rumours started to swirl that X-IO Technologies might be stepping away from the AFA business….

When Did Hard Drives Get Workload Rate Limits?

A recent article on The Register reminded me that we’ve started to see hard drive vendors introducing warranty limits on their hard drives for the amount of data that can be written to them in any one year.  Solid state drives have always had this restriction, because we know that flash is damaged by being… Read more »

A Quick Comment on IBM FlashSystem

It’s been pointed out to me from time to time that I don’t give IBM a fair mention when talking about all-flash systems.  According to Gartner, IBM are in the top right quadrant of the AFA MQ and therefore classed as leaders and visionaries.  So, let’s spend a few moments to discuss their strategy and products. TMS IBM… Read more »

Revisiting Seagate Kinetic Drives

Around 2.5 years ago, I blogged about the release of new object-based hard disk drives from Seagate called Kinetic.  The idea is that the drives don’t use traditional storage protocols like SAS and SATA, but instead store objects written and retrieved over Ethernet.  Effectively each drive is a large key-value store that manages it’s own content.  You PUT… Read more »

Hybrid Cloud and Data Mobility

I remember going to an HP(E) event back in 2011 (Discover Vegas I think) when the idea of hybrid cloud and converged infrastructure was just getting going.  HPE talked about the idea of “cloud bursting” – moving data and/or applications on demand into cloud infrastructure to cope with increased demand.  At the time I was… Read more »

Build or Buy – A Tale of Two All-Flash Strategies

Update: Andy Warfield of Coho Data has written a post on the FlashBlade architecture and decision choices to build/buy.  Find it here (link). Ever since flash was first added to traditional storage arrays back in 2008, there has been vigorous debate on the right approach to storage architectures for all-flash systems.  There are a number… Read more »

Storage Performance: Why I/O Profiling Matters

With a significant amount of annual IT budgets being spent on storage (25% by some estimates), the focus on making storage deliver to the needs of the business has never been greater.  However, despite the advances in flash technology, larger disk drives, the move to commodity and software defined storage, the problems faced by customers… Read more »
