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 »

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 »

NFS Vendor Benchmarks – Caveat Emptor

This week we’ve seen an update on NFS benchmarks with Hitachi announcing their latest results (via Hu’s blog) using HUS File and FMDs (Flash Module Drives).  Of course Hitachi wouldn’t be announcing if they hadn’t beaten EMC with the figures; no-one releases data that makes them look worse, after all.  But what are the data… Read more »
