For All-Flash Performance, Hardware vs. Media

In recent years the industry has seen the evolution of flash media from Serial Attached SCSI (SAS) and Serial Advanced Technology Attachment (SATA) based interconnects to Peripheral Component Interconnect Express (PCIe) based interconnects. And now, PCIe interconnect is standardized around

What is Extreme Performance?

The modern data center has to support many different types of workloads, each of which makes different demands on the storage architecture. Today, standard all-flash arrays (AFA) are the mainstream storage system for the data centers and conventional best practice

Why is Software Defined Storage Failing to Consolidate Storage?

After enterprises decide not to use the storage mainframe described in our last blog they often next investigate software-defined storage (SDS) as a means to consolidate their storage and reduce storage costs. With SDS, consolidation occurs at the storage software

Is Your All-Flash Storage Software Block Only?

Accelerating database performance remains a top use case for all-flash arrays, so it makes sense that most all-flash array systems only support block storage. However, only supporting block means that the customer assigns the “raw” volume to a server and
