Most primary storage systems and software provide some form of data protection. That protection comes in the form of protection from media failure (typically RAID), snapshots and clones. All-Flash Arrays (AFA) seem to provide a better than average level of…
The cloud is an ideal location from which to execute a disaster recovery. It eliminates the need for a secondary DR site and the processing power required by recovered applications because the organization purchases cloud storage and compute at the…
Scale-out storage systems tend to protect data from media failure in one of two ways; they either use replication or erasure coding. Replication creates a user-defined number of copies of data, typically a minimum of three, as it is created…
The flash optimized NVMe protocol has been on the market for over a year and the technology is available in several forms. NVMe, both storage and networking (NVMe over Fabrics) is more expensive than the typical SAS based solution and…
Legacy storage network architectures can’t keep up with the scale and performance requirements of modern data sets and workloads such as the Internet of Things (IoT) analytics, creating the need for transformation to support new business demands. Fibre Channel is…
High-Performance Computing (HPC) environments typically use parallel file systems as the core of their storage architecture. These environments also tend to leverage object storage as a near-line long-term repository of data. Object storage systems though, thanks to improved hardware and…
The previous blog in this series outlined the advantages of a diverse storage infrastructure; flexibility, workload specific performance, and hard-cost savings. The challenge with a diverse storage infrastructure is how to manage it. In prior blogs, we’ve looked at several…
Parallel file systems are a critical aspect of most Super Computing environments. One of the challenges facing parallel file systems is making sure the file system itself does not become a bottleneck. If not architected correctly, IO can overwhelm the…
The flash+object storage architecture creates a cost effective, two tier storage architecture in the data center. It enables IT to better meet performance demands of applications and the retention demands of unstructured data. Ideally the organization can reduce the size…
A web-scale data center needs to scale to support thousands if not millions of users. Web-scale application use cases range from traditional transactional IT to modern data analytics and machine learning workloads. It also includes new advanced video applications and…
