2019 will be the year that new CPUs and motherboards supporting the fourth generation of the Peripheral Component Interconnect Express (PCIe) interface (PCIe 4.0) will come to market – meaning that new storage systems using the interface are also on…
Several NVMe flash vendors are claiming that NVMe Flash has reached price parity with Serial Attached SCSI (SAS) based flash. The claim is true or pretty close to true in most situations. Vendors are selling their NVMe flash drives for…
When migrating to new technology, it is always important to conduct a careful cost/benefit analysis, to understand what the return on the new investment will be. It is also necessary to be sure that the investment will provide desired outcomes…
Non-volatile memory express (NVMe) is arguably one of the most important new technologies to make its way into the data center, because it is capable of delivering the ultra-fast levels of performance that are required by a growing number of…
Almost every storage vendor that used to just make SAS-based all-flash arrays is now shipping an NVMe Flash Array. New storage vendors are emerging that are skipping SAS-flash altogether and are starting with NVMe systems. The question facing IT planners…
Non-volatile memory express (NVMe) is among the most hyped storage technologies of 2019 – and for good reason. As previously covered by Storage Switzerland, NVMe’s ability to increase queue depths and command counts and to connect directly to storage memory,…
Enterprises are relying on a growing number of applications to run their business. At the same time, these applications carry requirements including performance levels that are simultaneously more divergent and dynamic than ever before. New applications are being spun up…
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…
Non-volatile memory express (NVMe) storage media and NVMe-over Fabrics (NVMeoF) storage network protocols open the door for new levels of performance and latency demanded by intensive, modern workloads such as big data analytics and artificial intelligence. However, the higher price…
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…
