Fixing the Problem of I/O With Parallel Computing – DataCore MaxParallel

The idea of improving the performance of applications through the use of parallel computing isn’t a new concept.  Look back 50 years and we can see that Amdahl’s Law shows how to predict the performance improvement that can be achieved by using multiple processors.  You can find details of Amdahl’s Law on Wikipedia, but essentially… Read more »

It’s Time for Hard Drives to Join Tape In The Archive Tier

This week we’ve seen the announcement of 14TB 3.5” hard drives from one vendor and 12TB from another. It’s hard to imagine the concept of 14TB in a single hard drive when ten years ago we were looking at only 1TB devices. However, these devices have a problem. The throughput and latency has remained relatively… Read more »

Focus on High Performance NAS

Block-based storage (and particularly that based on Fibre Channel) has always been the favoured child when it comes to vendors talking about their products and solutions.  All of the high-end performing devices tend (but not exclusively) to be block-based.  However we’re seeing an increased focus on high performance NAS platforms, especially those with scale-out capabilities….

Are DataCore’s SPC Benchmarks Unfair?

DataCore has been active over recent months with benchmarks based on their new SANsymphony Parallel Server offering.  The most recent of these claims 5.1 million SPC-1 IOPS at $0.08/SPC-1 IOPS and 0.32 millisecond response time.  Other vendors are crying foul on these results, claiming they don’t represent a true test because all of the data… 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 »

More Thoughts on Storage Performance – Measuring with Load DynamiX

In a previous post, I wrote about how improvements in storage performance have been achieved through changes to software.  Vendors like DataCore and Nutanix have implemented significant improvements that are in some cases quite remarkable.  As the storage market diverges into dozen’s of vendor platforms, how can end users validate the claims vendors are making?  Verifying vendor… Read more »
