Cohesity named a Leader again! 2023 Gartner® Magic Quadrant™ for Enterprise Backup and Recovery Software Solutions
With compute, memory and a network that can provide a sub millisecond latency to applications, the storage latency of 5-15ms becomes a bottleneck when a very low latency is required. This situation sparked a new revolution in the primary storage business with the advent of the expensive low latency All Flash Arrays (AFAs) and hybrid storage (SSD+HDD with Intelligent Lifecycle Manager -ILM).
a) All Flash Arrays
All Flash Array (AFA) storage systems are expensive, so using it for any purpose other than to read and write the application data is not cost-effective. If the storage architects want to replicate the primary data to a remote site for Disaster Recovery(DR) purpose, they need a similar expensive High Availability(HA) pair on the remote site as well.
b) Hybrid Storage Arrays
The storage architects can use the hybrid storage array, but then they have to right size the SSD tier. the active workset can become unpredictable due to the change in application workload, multiple reads by the backup subsystem, and when running the analytics on the primary storage.
So, in addition to managing the application performance expectations, the following features must be provided
Many of the features can be offloaded to the secondary storage system.
The ability of secondary storage to take on many of the functions of the primary has created a huge market.
Shortcomings of the existing backup products:
In short, the existing backup solution is built for backup and it cannot do anything else.
In addition to backup, the following features make the secondary storage platform interesting.
I will blog about these features in the future. I am still learning the ropes of secondary storage and would love your feedback.
