Remaining rated write endurance

NAND SSDs have a nite number of program erase cycles. The NVMe PCIe SSD is warranted to a maximum amount of data written to the

device in total bytes written. The NVMe PCIe SSD self monitors for these limits, and software management applications notify you when

you reach these limits.

NOTE: If you continue to write to the device after it reaches the threshold of total bytes written, the amount of time the NVMe

PCIe SSD retains data while powered o decreases below device specications. For more information, see Technical

specications.

Device write status

NAND SSDs have a nite number of spare sectors. If the device exhausts the available spare sectors, the NVMe PCIe SSD enters Write

Protect (Read-Only) mode. In Write Protect mode, you can only perform read operations to the device. The NVMe PCIe SSD self-

monitors for these limits, and software management applications notify you when you reach these limits.

Supported operating systems for NVMe PCIe SSD

NOTE: NVMe PCIe SSD hot swap is not supported in VMware ESXi 5.5 or while accessing the BIOS or Hll

conguration.

NOTE: For all operating system documents, see Dell.com/operatingsystemmanuals.

NOTE: NVMe PCIe SSD is not supported as a boot device in SUSE Linux Enterprise Server 11 or VMware.

Only the following operating systems support the NVMe PCIe SSD devices:

• Microsoft Windows Server 2016

• Red Hat Enterprise Linux 7.0 or later

• SUSE Linux Enterprise Server 12 or later

• VMware ESXi 6.0 or later
