Are Storage Systems Designed for NVMe?

Pavilion Data is glad to see established vendors such as Dell-EMC and Pure Storage entering the NVMe-based storage bandwagon. There are two categories of storage devices leveraging NVMe: Traditional Shared Storage Shared Accelerated Storage Traditional Shared Storage is used for scale-up workloads and usually a replacement for existing SATA or SAS-based All Flash Arrays (AFA) utilizing Fiber Channel or iSCSI protocols. To leverage NVMe, these systems are retrofitted in two ways:  1) media replacement with NVMe, and 2) replace the internal controller-to-drive interconnect bus from SAS/SATA to NVMe.  No other change in architecture is usually done. This provides a performance…

Next Generation Storage With No Compromise

Businesses are transforming to be more digital and are constantly in the quest of getting a competitive advantage over their competitors. One of the important and popular means is to do more with the data that they have. We all know that the amount of data as in volume, velocity and variety are continuing to grow unabated. To maintain competitive edge in the digital era implies the ability to take control of this deluge, analyze and deliver insights accurately to better serve business needs. This has turned the focus back to storage software, storage media and systems as it was…

Different Approaches for Delivering Ultra Low Latency Shared Storage

Several new storage systems have come to market with the goal of delivering shared flash resources as a service to high-scale, distributed applications. These products take advantage of some of the following technology developments in the storage and networking space: Standards-based PCIe-Connected SSDs, RDMA-Capable Ethernet Networking up to 100 Gbe, a standard storage protocol designed for PCIe-Connected SSDs (NVMe), and a standard protocol for remotely Accessing NVMe devices (NVMe-Over-Fabrics, or NVMe-oF).   Note that Red Hat 7.4 and Ubuntu 16 both now include NVMe-oF support inbox. These 4 technologies can allow applications to get performance from networked storage similar to SSDs installed directly in…
