Storage Layout  

The Cisco HyperFlex HX Data Platform controller handles all read and write requests for volumes that the 

hypervisor accesses and thus mediates all I/O from the virtual machines. The hypervisor has a dedicated boot disk 

independent of the data platform. 

Incoming data is distributed across all nodes in the cluster to optimize performance using the caching tier. Effective 

data distribution is achieved by mapping incoming data to stripe units that are stored evenly across all nodes, with 

the number of data replicas determined by the policies you set. When an application writes data, the data is sent to 

the appropriate node based on the stripe unit that includes the relevant block of information. This data distribution 

approach in combination with the capability to have multiple streams writing at the same time helps prevent both 

network and storage hot spots. It also delivers the same I/O performance regardless of virtual machine location 

and provides more flexibility in workload placement.
