Did you know?

NVMe (Non-Volatile Memory Express) is a technology that overcomes SAS/SATA SSD performance limitations by optimizing hardware and software to take full advantage of flash technology. The use of NVMe Flash Storage Adapters means data is transferred more efficiently from the processor to the storage compared to the legacy Advance Host Controller Interface (AHCI) stack, thereby reducing latency and overhead. These Flash Storage Adapters connect directly to the processor via the PCIe bus, further reducing latency and TCO compared to SAS/SATA SSDs.

Lenovo Performance Flash Storage Adapters are suitable for write-intensive data center workloads, and the PCIe form factor rather than a 2.5-inch drive form factor gives you an alternative way to add high performance storage to your server. Overall, these adapters provide outstanding IOPS/watt and cost/IOPS for enterprise solutions.

Features

Non-Volatile Memory Express (NVMe) is new PCIe 3.0 high performance solid-state storage technology that provides high I/O throughput and low latency. NVMe interfaces remove SAS/SATA bottlenecks and unleash all of the capabilities of contemporary NAND flash memory. Each Flash Storage Adapter has direct PCIe 3.0 x4 connection, which provides at least 2x greater bandwidth and 2x lower latency than SATA/SAS-based SSD solutions. NVMe Flash Storage Adapters are also optimized for heavy multi-threaded workloads by using internal parallelism and many other improvements, such as larger I/O queues.

The Lenovo NVMe Performance Flash Adapters have the following features:

  • Half-high half-length PCIe adapter with PCIe 3.0 x4 host interface
  • Based on the Toshiba PX04P Add-in Card (AIC), PX04PMCxxx
  • 19nm MLC NAND (128 Gb/die)
  • 10 drive-write-per-day (DWPD) endurance for write-intensive workloads
  • Full Power-Loss-Protection and End-to-End Data Protection
  • Low power consumption (maximum 18.5 W)

Enterprise Performance Flash Adapters and Enterprise Mainstream Flash Adapters have similar read IOPS performance, but the key difference between them is their endurance (or lifetime) (that is, how long they can perform write operations because Flash Adapters (like SSDs) have a finite number of program/erase (P/E) cycles). Enterprise Performance Flash Adapters have higher endurance compared to Enterprise Mainstream Flash Adapters. Write endurance is typically measured by the number of program/erase (P/E) cycles that the adapter incurs over its lifetime, listed as the total bytes of written data (TBW) in the device specification.

The TBW value assigned to a Flash Adapter is the total bytes of written data (based on the number of P/E cycles) that an adapter can be guaranteed to complete (% of remaining P/E cycles = % of remaining TBW). Reaching this limit does not cause the adapter to immediately fail. It simply denotes the maximum number of writes that can be guaranteed. A Flash Adapter will not fail upon reaching the specified TBW. At some point based on manufacturing variance margin, after surpassing the TBW value, the adapter will reach the end-of-life point, at which the adapter will go into a read-only mode.

Even though Enterprise Performance Flash Adapters have high endurance, careful planning must still be done to ensure that the total amount of data expected to be written to the drive over its life will not exceed the stated total bytes written (TBW) property of the drive.

For example, the 1.6 TB adapter has an endurance of 29,200 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 16 TB of writes per day, which is equivalent to 10.0 full "drive" writes per day (DWPD). For the device to last three years, the write workload must be limited to no more than 26,667 GB of writes per day, which is equivalent to 16.7 full drive writes per day.

Warranty

The adapters carry a one-year, customer-replaceable unit (CRU) limited warranty. When the adapters are installed in a supported server, these adapters assume the system’s base warranty and any warranty upgrades.

Solid State Memory cells have an intrinsic, finite number of program/erase cycles that each cell can incur. As a result, each solid state device has a maximum amount of program/erase cycles to which it can be subjected. The warranty for Lenovo Flash Storage Adapters is limited to adapters that have not reached the maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the product. An adapter that reaches this limit may fail to operate according to its Specifications.
