Activation Architecture Capacity Failover 
AWS Disaster Recovery
JULY 27, 2021
In this blog post, we share a reference architecture that uses a multi-Region active/passive strategy to implement a hot standby strategy for disaster recovery (DR). With the multi-Region active/passive strategy, your workloads operate in primary and secondary Regions with full capacity. This keeps RTO and RPO low.

It’s not always an easy engineering feat when there are fundamental architectural changes in our platforms, but it’s a core value that you can upgrade your FlashArrays without any downtime and without degrading performance of business services. . The only observable activity is path failovers, which are non-disruptively handled by MPIO.

The Storage Architecture Spectrum: Why “Shared-nothing” Means Nothing by Pure Storage Blog This blog on the storage architecture spectrum is Part 2 of a five-part series diving into the claims of new data storage platforms. And just as important, why there is more to any product or platform than just architecture.

Active/passive and active/active DR strategies. Active/passive DR. Figure 2 categorizes DR strategies as either active/passive or active/active. In Figure 3, we show how active/passive works. All requests are now switched to be routed there in a process called “failover.”

In this blog post, you will learn about two more active/passive strategies that enable your workload to recover from disaster events such as natural disasters, technical failures, or human actions. These are both active/passive strategies (see the “Active/passive and active/active DR strategies” section in my previous post).

Resource Balancer only uses capacity-free space to determine where to place the new volume.¹³ This is why PowerStore can support different models with different capacities in the same “cluster,” because data is located only on one appliance at a time. Item #3: “ Active/Active Controller Architecture”¹⁴ Is a Good Thing We see this B.S.

In Part II, we’ll provide technical considerations related to architecture and patterns for resilience in AWS Cloud. Considerations on architecture and patterns. Resilience is an overarching concern that is highly tied to other architecture attributes. Let’s evaluate architectural patterns that enable this capability.
