Activation Capacity Failover

I use these examples to illustrate the huge difference between a simple active-passive database running on two servers and a scalable cloud-native database that gets lost when you describe a system merely as “shared-nothing.” And with Pure Storage’s shared-NVRAM approach, this makes controller failover events completely non-disruptive.

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.

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.”

HDD devices are slower, but they have a large storage capacity. Even with the higher speed capacity, an SSD has its disadvantages over an HDD, depending on your application. Traditionally, the biggest disadvantages of an SSD have been price, degradation, and capacity. SSD devices are faster, but they also cost more.

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.

The capacity listed for each model is effective capacity with a 4:1 data reduction rate. . Pure Cloud Block Store provides the following benefits to SQL Server instances that utilize its volumes for database files: A reduction in cost for cross availability zone/region traffic and capacity consumption.
