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 PCIe SSD is designed based on Single Level Cell (SLC) and Multi-Level Cell (MLC) NAND flash technology with a high-speed PCIe 2.0 or PCIe 3.0 compliant interface. In 14th generation of PowerEdge servers, we have three different ways to connect SSDs. You can use an extender to connect the SSDs via backplane, directly connect the SSDs from backplane to mother board using slimline cable without extender, and use HHHL (Add-In) card which sits on the motherboard.
NOTE: : 14th generation of PowerEdge servers are supporting Industry standard NVMe-MI specification based NVMe SSDs. However, 13th generation of PowerEdge servers used to support Dell proprietary specification based SSDs. Adding SSDs from any previous generation of server are not supported by iDRAC9.
Using iDRAC interfaces, you can view and configure NVMe PCIe SSDs.
In few of the 14th generation of PowerEdge servers, up to 32 NVMe SSDs are supported.
NOTE: : Hot plug capability, prepare to remove, and blink or unblink the device LED is not applicable for HHHL PCIe SSD devices.
NOTE: : When NVMe devices are controlled behind S140, prepare to remove and cryptographic erase operations are not supported, blink and unblink are supported.
