Drive trays

The drive tray contains data 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 flash storage devices. To deliver consistent low latency host response times and highest IOP performance across all host connection ports, conventional hard disk drives (HDD) are not included or configurable with all-flash arrays.
