Hybrid Flash Arrays and All-Flash Arrays are fundamentally changing the way IT designs storage architectures. IT can create virtual environments with much higher virtual machine to physical server ratios, scale-up databases to support exponentially more users and add new workloads…
Workload modeling is the process of capturing the IO patterns of a workload so that it can be played back later in a different environment. The goal is to provide a very close simulation of how that workload will respond…
As Storage Switzerland previously blogged, non-volatile memory express (NVMe) access protocols stand to add value to a host of applications, ranging from the performance-intensive newer workload set (e.g. artificial intelligence) to more traditional Tier 1 applications (e.g. Microsoft SQL Server).…
The introduction of the non-volatile memory express (NVMe) storage protocol brings with it a new storage performance tier. Whereas older Small Computer System Interface (SCSI) and Advanced Technology Attachment (ATA) standards were designed for slower-performing hard disk drive (HDDs) and…
The next step in all-flash performance is NVMe. Systems equipped with NVMe support promise to increase performance and lower latency. But, IT professionals want to know if their data centers can take advantage of NVMe and how they should plan…
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…
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…
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…
Recently, storage vendors started to promote a concept of evergreen storage. Essentially, the vendor will swap out the customer’s storage hardware with the latest, more capable hardware at some point in the maintenance contract. The problem is this swap-out is…
