Disaggregation enables on-demand resource pool management and creation

Disaggregation may not be a new concept, but it has become more important to IT in recent years. Here, it means breaking computers down to the core elements of compute, memory, I/O, storage, cache, network fabric and so on, to enable resource pool management and create more agile, cost-effective data centers. Done correctly, disaggregation lets you stand up and break down infrastructures almost instantly while better serving the needs of individual applications. Meanwhile, resource utilization soars, and resource pool management costs decline because of the automation that's enabled. Delve into the world of disaggregation and find out how vendors are applying the concept to their products.

Hybrid cloud storage can let you run, manage and move primary storage workloads between the cloud and on-premises data center. It can also improve IT agility and cut costs. Today, a number of products and services fulfill the promise of the hybrid cloud like never before, knocking down barriers that have inhibited wider adoption. Hybrid cloud products open new possibilities for deploying production applications, but you must choose wisely.

Pundits have predicted the demise of the hard disk for years. Not only is solid-state much faster than hard disks, the price differential between the two storage technologies is rapidly disappearing. Yet the HDD vs. SDD controversy continues with the death of the former still a long way off. The question shouldn't be when hard disks will disappear, but instead, how to best use flash technology within the memory-storage continuum that starts with tape and goes to L1 cache, the fastest and most expensive memory in a system.
