Lenovo PM983 Entry NVMe PCIe SSDs
Product Guide
The Lenovo PM983 Entry NVMe PCIe solid-state drives (SSDs) in capacities from 1.92 TB to 7.68 TB are general-purpose yet high-performance SSDs for System x and ThinkServer systems. They are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads. Lenovo PM983 Entry NVMe PCIe SSDs

Did you know?
The PM983 family of SSDs are follow-ons to the PM963 drives. The PM983 drives offer improved performance, both in terms of random read/write performance (IOPS) and sequential read/write bandwidth (MB/s). Sequential write latency has also been improved.
Lenovo Entry SSDs are suitable for read-intensive and general-purpose data center workloads, however their NVMe PCIe interface means the drives also offer high performance. Overall, these SSDs provide outstanding IOPS/watt and cost/IOPS for enterprise solutions.Click here to check for updates Lenovo PM983 Entry NVMe PCIe SSDs

Features

Non-Volatile Memory Express (NVMe) is PCIe 3.0 high performance SSD 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 NVMe PCI SSD has direct PCIe 3.0 x4 connection, which provides at least 2x more bandwidth and 2x less latency than SATA/SAS-based SSD solutions. NVMe drives are also optimized for heavy multi-threaded workloads by using internal parallelism and many other improvements, such as enlarged I/O queues.
The PM983 Entry NVMe PCIe SSD have the following features:

Available in 2.5-inch (U.2) and 3.5-inch form factors
Low cost, read-intensive SSD from Samsung
Direct PCIe 3.0 x4 connection for each NVMe drive, resulting in up to 4 GBps overall throughput.
Advanced ECC Engine and End-to-End Data Protection
Samsung 32 layer V-NAND stacks the vertical NAND layers in three dimensions, solving the cell-tocell interference that causes data corruption in planar NAND.
Protect data integrity from unexpected power loss with Samsung’s advanced power-loss protection architecture
Supports Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T).

Entry SSDs and Performance SSDs have similar read IOPS performance, but the key difference between them is their endurance — how long they can reliably perform write operations. Entry SSDs have a better cost/IOPS ratio but lower endurance compared to Performance SSDs. SSD write endurance is typically measured by the number of program/erase (P/E) write cycles that the drive incurs over its lifetime, listed as the total bytes of written data (TBW) in the device specification.
The TBW value assigned to a solid-state device is the total bytes of written data (based on the number of P/E cycles) that a drive can be guaranteed to complete (% of remaining P/E cycles = % of remaining TBW). Reaching this limit does not cause the drive to immediately fail. It simply denotes the maximum number of writes that can be guaranteed. A solid-state device will not fail upon reaching the specified TBW. At some point based on manufacturing variance margin, after surpassing the TBW value, the drive will reach the end-of-life point, at which the drive will go into a read-only mode.
Because of such behavior by Entry solid-state drives, careful planning must be done to use them only in read-intensive or mixed up to 70% read/30% write environments to ensure that the TBW of the drive will not be exceeded before the required life expectancy.
For example, the PM983 Entry 3.84 TB drive has an endurance of 5466 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 2995 GB of writes per day, which is equivalent to 0.8 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 4992 GB of writes per day, which is equivalent to 1.3 full drive writes per day.

Server support

The following tables list the ThinkSystem servers that are compatible.
Table 3. Server support (Part 1 of 2)

Storage controller support
NVMe PCIe SSDs require a NVMe drive backplane and some form of PCIe connection to processors. PCIe connections can take the form of either an adapter (PCIe Interposer or PCIe extender) or simply a cable that connects to an onboard NVMe connector.
Consult the relevant server product guide for details about required components for NVMe drive support.
Operating system support
The following tables list the supported operating systems.

Warranty

The PM983 Entry NVMe PCIe SSDs carry a one-year, customer-replaceable unit (CRU) limited warranty.
When the SSDs are installed in a supported server, these drives 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 solid state drives (SSDs) is limited to drives that have not reached the maximum guaranteed number of program/erase cycles, as documented in the Official Published Specifications for the SSD product. A drive that reaches this limit may fail to operate according to its Specifications.
