Dell PowerStore Hardware Information Guide for PowerStore 500T Model

The 2U, 25-drive base enclosure consists of the following components:

• Slots for 25 2.5-inch NMVe drives
• Midplane
• Two nodes
• Power supply module (AC or DC)
• EMI shielding

Drives

Each drive resides in a drive carrier. The drive carriers are metal and plastic assemblies that provide smooth, reliable contact with the enclosure slot guides and mid-plane connectors. Each carrier has a handle with a latch and spring clips. The latch holds the drive in place to ensure proper connection with the mid-plane. Drive activity and fault LEDs are on the front of the enclosure.

There are two supported drive types:

• NVMe SSD
  • The NVMe SSD drives in the PowerStore 3200Q are QLC-based.
  • The NVMe SSD drives in all other PowerStore models are TLC-based.
• NVMe SCM

You can mix NVMe SSD and NVMe SCM drives in the same base enclosure. If you mix drive types, the system uses the NVMe SCM drives for metadata tiering.

Midplane

The mid-plane separates the front-facing drives from the rear-facing nodes. It distributes power and signals to all components in the enclosure. The nodes and drives plug directly into the mid-plane.

Nodes

Each base enclosure contains two nodes. The node is the intelligent component providing the compute capability of the base enclosure.

Node power supply module

Each node contains a power supply module that connects the system to an exterior power source. The system supports either AC power or DC power. If one power supply fails, the redundant power supply can keep the entire base enclosure running. The power supplies include LEDs to indicate component status. A latch on the module locks it into place to ensure proper connection.

EMI shielding

EMI compliance requires a properly installed electromagnetic interference (EMI) shield in front of the base enclosure drives. When installed in cabinets that include a front door, the base enclosure includes a simple EMI shield. Other installations require a front bezel that has a locking latch and integrated EMI shield. Remove the bezel or shield to remove and install the drives.
