What is Docker?
Docker is a computer program that performs operating-system-level virtualization, also known as “containerization”. It was first released in 2013 and is developed by Docker, Inc. source: Wikipedia
How Docker works?
Docker containers wrap up software and its dependencies into a standardized unit for software development that includes everything it needs to run: code, runtime, system tools, and libraries. This guarantees that your application will always run the same and makes collaboration as simple as sharing a container image.
Docker unlocks the potential of your organization by giving developers and IT the freedom to build, manage and secure business-critical applications without the fear of technology or infrastructure lock-in. source: www.docker.com
In VMAX3 or any enterprise-class storage arrays, hot spares are used to replace failing or failed disks in the storage array. Hot Spare drives need to be of the same configuration and size (can be larger) as that of the failing/failed disk. VMAX3 with Hypermax use Direct Sparing to automatically replace a failing disk.

This script would fetch hot spare drives count per VMAX3 array and generates a dash. This dash shows compliance report across all DCs.
Data Storage cleanup/reclaim is similar to how we manage “kinds of stuff” in our homes. We think what to keep and not to after taking the holistic decision. Time & Value will decide what is to be discarded in near future…
An All-Flash Storage array (AFA’s) gives the best performance and greater value to the business. But every GB of All-Flash Storage is at least 3 times costlier than that of mechanical drives. It is critical to perform frequent clean up of these kinds of arrays to make sure that only the mission/business critical data and deserving information should reside on All-Flash array.
From the business perspective, the concerned team needs to do the regular drills to identify then inform IT Ops to discard stale or amassed data ASAP. This requires the team to do a logical distinction of information based on value or tasks, seek approvals from respective Business Unit Owners before proceeding to do clean up.
