Lenovo ThinkSystem 7400 PRO Read Intensive NVMe PCIe 4.0 SSDs User Guide

Lenovo ThinkSystem 7400 PRO Read Intensive NVMe PCIe 4.0 SSDs

The ThinkSystem 7400 PRO Read Intensive NVMe SSDs are general-purpose yet high-performance family of NVMe solid-state drives. They are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads. The 7400 PRO SSDs (also known as 7400P drives) are based on the Micron 7400 PRO family of PCIe 4.0 NVMe drives.

Did you know?

• Lenovo Read Intensive (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.
• Lenovo also offers the 7400 PRO SSDs in an M.2 form factor. See the ThinkSystem M.2 Drives and M.2 Adapters product guide for information, https://lenovopress.com/lp0769

Features

Non-Volatile Memory Express (NVMe) is PCIe 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 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 ThinkSystem 7400 PRO Read Intensive NVMe SSDs have the following features:

• Based on the Micron 7400 PRO family of SSDs
• Micron 96-layer 3D TLC NAND
• NVMe SSD with PCIe 4.0 performance and a U.3 interface
• Direct PCIe 4.0 x4 connection for each NVMe drive, resulting in up to 8 GBps overall throughput. Advanced ECC Engine and End-to-End Data Protection
• Protect data integrity from unexpected power loss with advanced power-loss protection architecture
• Adaptive Thermal Monitoring to monitor the internal temperature of the drive with power adjustment to ensure operation within thermal limits
• Supports Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T).
• Enterprise-level security features:
  • Secure Execution Environment – dedicated security processing hardware with physical isolation
  • Asymmetric Roots of Trust – Enables authenticated revocation of root keys
  • Strong Asymmetric Key Support – Uses standard, NIST-approved algorithms with 208-bit/3072-bit RSA keys
  • RSA Delegation Key Support – Enables customers to maintain ownership of RSA keys
  • Secure Boot – Helps ensure firmware integrity on running platform
  • Key-Based Firmware Update – Validates firmware using public key-based authentication prior to firmware update
  • Key-Based Privileged Access – Protects against unauthorized privileged SSD function execution with public key-based authorization
• Read Intensive SSDs and Write Intensive SSDs have similar read IOPS performance, but the key difference between them is their endurance — how long they can reliably perform write operations. Read Intensive SSDs have a better cost/IOPS ratio but lower endurance compared to Write Intensive 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 Read Intensive solid-state drives, careful planning must be done to use them only in read-intensive or mixed use (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 1.92 TB 7400 PRO drive has an endurance of 3,500 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 1,918 GB of writes per day, which is equivalent to 1.0 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 3,196 GB of writes per day, which is equivalent to 1.7 full drive writes per day.

Server support

The following tables list the ThinkSystem servers that are compatible.

Table 4. Server support (Part 2 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.

Warranty

• The ThinkSystem 7400 PRO Read Intensive NVMe 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.
