Can the WekaIO Matrix file system be faster than DAS?

There’s a standard adage in the storage industry.  If you want lower latency and better performance, then move storage closer to the processor.  Typically, this means implementing DAS – Direct Attached Storage – and eliminating a shared network.  So how can WekaIO Matrix, a distributed scale-out file system claim to be better than DAS yet… Read more »

Why is HPE 3PAR not moving to NVMe SSDs (yet)?

During our coffee talks at HPE Discover 2018, statements were made that claimed HPE 3PAR storage platforms wouldn’t benefit much from going to NVMe at the back end.  Instead, the statement of direction is to use storage-class memory as a platform accelerator.  I’ve been trying to understand why HPE isn’t making the move at this… Read more »

Avoiding the Storage Performance Bathtub Curve

We’re probably all familiar with the concept of the HDD or SSD reliability bathtub curve (figure 1).  This shows how over the lifetime of a drive, failures typically follow a pattern where failure rate increases over time to a steady state, then increases again as the device wears out.  But have you considered the idea… Read more »

Avoiding All-Flash Missing IOPS

We are living in a golden age of storage media, where new products come to market offering ever greater performance with lower latency than previous generations.  Today the hard drive and even early flash drives look positively archaic compared to modern NVMe drives built from 3D-XPoint, capable of delivering hundreds of thousands of IOPS and… Read more »
