Most commercial storage architectures require clusters to be built from homogenous pools of servers and storage. So when it comes time to add performance, most storage administrators are faced with very rigid rules for adding new nodes to a cluster or even worse, forklift upgrades of whole clusters.
The fully disaggregated architecture of the VAST Data Platform is designed to support asymmetrical expansion, making it simple to add heterogeneous resources to the shared pools of CPU resources and SSDs that compose a VAST cluster. With compute decoupled from storage, adding new CPUs to a VAST cluster, there is no need for a lengthy expansion process that impacts the performance typical of legacy architectures.
