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.
