Overview
Dell PowerEdge Express Flash Peripheral Component Interconnect Express (PCIe) Solid State Device (SSD) is a high
performance storage device designed for solutions requiring low latency, high input/output operations per second
(IOPS), and enterprise class storage reliability and serviceability. The Dell PowerEdge Express Flash PCIe SSD is offered
as a Single-Level Cell (SLC) and Multi-Level Cell (MLC) NAND flash technology with a high-speed PCIe 2.0 compliant
interface. The high-speed PCIe 2.0 compliant interface helps improve performance for I/O bound solutions.
NOTE: Dell PowerEdge Express Flash PCIe SSD is not supported as a bootable device.
NOTE: Dell PowerEdge Express Flash Peripheral Component Interconnect Express Solid State Device is hereinafter
referred to as PCIe SSD.
PCIe SSD Architecture
The PCIe SSD solution consists of a PCIe extender adapter card, which provides PCIe connectivity for up to four PCIe
SSDs at the front of the chassis. The number of supported PCIe SSDs depends on the system.
PCIe SSDs from Dell are available in 175 GB and 350 GB (SLC) or 700 GB (MLC) capacities and are supported on Dell
PowerEdge systems.
In Dell PowerEdge rack and tower systems, the PCIe extender adapter card connects to a PCIe SSD backplane, allowing
connectivity for up to four PCIe SSDs. In PowerEdge modular systems, the PCIe extender modular card connects to the
PCIe SSD backplane, allowing connectivity for up to two PCIe SSDs.
NOTE: To determine the maximum number of PCIe SSDs supported on your system, see the system-specific
Owner’s Manual at dell.com/support/manuals.
The following figures show different components of the PCIe SSD solution.
