Dell PowerFlex 4.5.x Technical Overview
Hardware
Hardware can be the existing application servers used by the data center, or a new set of nodes (if, for example, you want to dedicate all nodes solely for running the PowerFlex SAN storage system).
The PowerFlex rack system includes a full data center solution including: rack, switches, server nodes, power, and cabling. Built for capacity, performance, or compute per the specific configuration.
- Servers are the basic computer units used to install and run PowerFlex. They can be the same servers used for the applications (server convergence), or a dedicated cluster. In any case, PowerFlex is hardware-agnostic so aside from performance considerations, the type of server is inconsequential.
- The storage media can be any storage media, in terms of the type (HDD, SSD, NVMe SSD or PCIe flash cards) and anywhere (external).
