Storage system drive trays
The drive trays contain drives, power supplies, fans, and status LEDs. Each drive tray provides interfaces for connecting to controllers and other drive trays. The all-flash storage arrays have various fixed storage capacity configurations with FMD DC2 flash storage devices. To deliver consistent low latency host response times and highest IOP performance across all host connection ports, conventional HDDs are not included or configurable with all-flash arrays.
