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 »

MAX Data: Optimising Application Performance with SCM

As the slowest part of the computing architecture, persistent storage is in a constant battle to improve performance.  That goal has moved from being focused on throughput a few decades ago to one of reducing latency as low as possible.  To that end, NVM Express and NVMe over Fabrics have become an area of focus… Read more »

Performance Benchmarks: Reading Between the Lines

As we move into 2019, storage performance becomes more important than ever.  At the media level, vendors are pushing the boundaries with fast solid-state technologies like NAND flash and 3D-Xpoint.  These products provide performance capabilities we’ve never seen before.  Storage system vendors then take components and build storage solutions, either as bespoke hardware or part… Read more »

Why Deterministic Storage Performance is Important

In the days of spinning media, I/O performance was anything but consistent.  When mechanical head movement is involved, response time can vary enormously.  Actually, the variation of I/O isn’t just to do with mechanics as we will discuss in a moment.  However, inconsistent I/O response time is a problem for applications and as tolerances reduce,… 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 »

INFINIDAT InfiniSync – Infinite Sync Replication

Data replication is a core enterprise feature for implementing data protection.  Synchronous replication provides the ability to maintain an identical copy of data at another location.  While not a panacea for every problem, sync replication simplifies the protection process for servers and applications that are contained on one or more LUNs/volumes. INFINIDAT recently announced InfiniSync,… Read more »

Storage Performance Benchmarks in Light of Spectre/Meltdown

This week E8 Storage announced that the company had successfully beaten the SPEC SFS 2014 benchmark, with a test based on an E8 appliance and IBM Spectrum Scale (GPFS).  The test chosen was software build, which generates lots of I/O activity across many files.  As the press release from E8 says, this workload emulates the… Read more »

Accelerating Workloads with NetApp Plexistor

I hadn’t realised that NetApp acquired Plexistor earlier this year.  Depending on which site you look at, the acquisition was a pretty cheap $20m or $32m, based on an A-round investment of around $4.5m in September 2014.  NetApp demonstrated application acceleration using the Plexistor technology at Insight in Berlin last week (see the day 2… Read more »
