Although NVMe SSDs are a highly reliable storage technology, they are still prone to occasional failure. Here are some best practices to keep your SSDs humming along

"Compared to hard drives, SSDs are remarkably reliable; yet, no storage technology is perfect. Even the latest NVMe SSDs are susceptible to a sudden or gradual breakdown.

Knowing how to spot the signs of an imminent SSD failure, as well as understanding how to troubleshoot a malfunctioning SSD, can mark the difference between permanent data loss and a trouble-free recovery. Like any storage device, an NVMe SSD will eventually fail; the only variable is when. Unlike hard drives, SSDs can't send an audible warning that something may be going wrong. Yet, while the SSD may be dead, all is not necessarily lost.

Here's a look at four leading causes of SSD failure and how to resolve the problems..."

Achieving Fast, Accurate NAS Migrations In 5 Key Steps, March 19th, 2020
Gartner estimates 83 percent of data migration projects either fail or exceed their budgets and schedules

"This is likely due to the fact that many companies still operate without the aid of dedicated migration software. Trying to navigate a Network-Attached Storage (NAS) migration with outdated and incompetent tools means:

  • High cost of both internal and external personnel
  • Increased risk across all aspects of the project from data integrity to reputation of the migration team
  • Increased number of switchover events with extended outage durations
  • Disruption to the business
  • Lack of proper reporting and governance
  • Skilled staff distracted by migrations instead of working on strategic initiatives

All these challenges can be avoided or significantly mitigated by following a solid migration process..."

Computer storage is both a blessing and a curse. We can store terabytes of photos, documents, and more at home

"But that data is more precarious than we might assume thanks to a phenomenon known as bit rot or data degradation.

Hard Drives and SSDs Don't Last Forever

Take a hard drive and an SSD and bury them with a book in a time capsule for 100 years. You can bet the book will be legible when it resurfaces, but the storage drives? Good luck...'"

Ceph Gets Fit And Finish For Enterprise Storage
The Next Platform, March 18th, 2020
Ceph, the open source object storage born from a doctoral dissertation in 2005, has been aimed principally at highly scalable workloads found in HPC environments and, later, with hyperscalers who did not want to create their own storage anymore

"For years now, Ceph has given organizations object, block, and file-based storage in distributed and unified cluster systems well into the tens of petabytes and into the exabyte levels, storage that takes high levels of expertise to deploy, run, and manage. Building and managing these massive object storage clusters takes the kind of skills that HPC, hyperscaler, cloud builder, and other service providers tend to have. But large enterprises and many Tier 2 and Tier 3 service providers do not have such skills.

And the workloads they need to run - either themselves or on behalf of clients - is driving demand for object storage among more mainstream enterprises, who want to leverage artificial intelligence, analytics, containers, and similar advanced technologies but who do not have the expertise to manage complex Ceph environments..."

The software-defined-storage (SDS) market is expected to register a 28% CAGR from 2019 through 2023

"As storage capacity grows due to the accumulation of data for video, big data, data analytics, AI and ML, an increasing portion of data center storage- spend is expected to shift towards SDS storage, which is suited for this new type of data retention and processing.

The SDS market comprises hyper-converged infrastructure (HCI) and standalone SDS products..."
