Server Disaggregation: Sometimes the Sum of the Parts Is Greater Than the Whole
The notion of “the whole being greater than the sum of its parts” is true for many implementations of technology. Take, for example, hyper-converged infrastructure (HCI) solutions like the Dell EMC VxRail. HCI combines virtualization software and software defined storage with industry standard servers. It ties these components together with orchestration and infrastructure management software to deliver a combined solution that provides operational and deployment efficiencies that, for many classes of users, would not be possible if the components were delivered separately.
However, certain challenges require separating out the parts – that’s where the solution is found. And, that is true in the case of Server Disaggregation and the potential benefits such an architecture can provide.
So, what is Server Disaggregation? It’s the idea that for data centers of a certain size, efficiencies of servers can be improved by dissecting the traditional servers’ components and grouping like components into resource pools. Once pooled, a physical server can be aggregated (i.e., built) by drawing resources on the fly, optimally sized for the application it will run. The benefits of this model are best described by examining a little history.
B.V.E. (Before the Virtualization Era)
Before virtualization became prevalent, enterprise applications were typically assigned to physical servers in a one-to-one mapping. To prevent unexpected interactions between the programs, such as one misbehaving program consuming all the bandwidth of a server component and starving the other programs, it was common to give critical enterprise applications their own dedicated server hardware.
