The purpose of the NVMe standard is to replace SCSI-based protocols, like SAS, so memory-based storage systems, like all-flash arrays, can live up to their full potential. Data centers may not need the performance potential of NVMe all-flash systems. But…
NVMe is a storage protocol designed specifically for flash-based storage. It is PCIe-based and provides more commands per IO queue and more IO queues. The NVMe over Fabrics (NVMe-F) extension gives IP and Fibre Channel (FC) networks the ability to…
Unstructured data applications are increasingly IO hungry. It’s a problem that impacts not only the High-Performance Computing (HPC) market, but also the traditional enterprise as they start initiatives like Machine Learning, Artificial Intelligence (AI) and Internet of Things (IoT). In…
The first step for NVMe flash is to use them internally in servers and storage systems. However, there is another aspect of NVMe, NVMe over Fabrics (NVMe-F) that promises high-speed communication between devices and also promises a new way to…
As member countries turn the European Union’s General Data Protection Regulation (GDPR) into domestic law, vendor’s are focusing on secondary storage, backup, archive and disaster recovery. But what about primary storage? Is it possible to architect a primary storage system…
There are three points within the storage infrastructure that will use NVMe; internal to the storage system, intra-connectivity between storage systems and inter-connectivity to physical servers. The first point of adoption will be in the storage system itself. As vendors…
Database applications like Oracle and MS-SQL make up most of the active data set. Making sure these applications respond almost instantly to user requests is a critical function for IT. The problem is meeting the instant response expectation is expensive,…
The storage industry isn’t changing; it is reshaping. What is the difference? If the industry were changing, it would be its choice to change, driven by internal motivations. Instead, outside influences are reshaping the industry. What are the primary drivers…
NVM Express (NVMe) is an optimized, high performance, scalable host controller interface with a streamlined register interface and larger command set designed for accessing memory-based storage attached through the PCIe bus. Put simply’ it is a better protocol for flash…
When flash storage first came to market it exposed the weakness in storage designs, hidden by the latency of hard disk media. Now, NVMe promises to expose weaknesses in the designs of the first generation of all-flash arrays. One of…
