4XB7A91175 ThinkSystem 9400 MAX Mixed Use NVMe PCIe 4.0 x4 SSDs

The ThinkSystem 9400 MAX Mixed Use NVMe SSDs are advanced data center SSDs optimized for mixed read-write performance, endurance, and strong data protection for Lenovo servers. With a PCIe 4.0 x4 interface, they are designed for greater performance and endurance in a cost-effective design, and to support a broader set of workloads.
No SED support: The drive described in this product guide does not supported SED encryption.

Did you know?

Lenovo Mixed Used SSDs like the 9400 MAX SSDs are suitable for mixed read- write 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.

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 9400 MAX Mixed Use NVMe SSDs have the following features:

• NVMe SSD with PCIe 4.0 performance and a U.2 interface
• Based on the Micron 9400 MAX family of SSDs
• Micron 232-layer 3D TLC NAND
• 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 208bit/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

SSDs have a huge but finite number of program/erase (P/E) cycles, which affect how long they can perform write operations and thus their life expectancy. Mixed Use SSDs have a higher write endurance compared to Read Intensive SSDs. SSD write endurance is typically measured by the number of program/erase cycles that the drive can incur over its lifetime, which is listed as total bytes written (TBW) in the device specification.
ThinkSystem 9400 MAX Mixed Use NVMe PCIe 4.0 x4 SSDs
The TBW value that is assigned to a solid-state device is the total bytes of written data that a drive can be guaranteed to complete. Reaching this limit does not cause the drive to immediately fail; the TBW simply denotes the maximum number of writes that can be guaranteed. A solid-state device does not fail upon reaching the specified TBW. However, at some point after surpassing the TBW value (and based on manufacturing variance margins), the drive reaches the end-of-life point, at which time the drive goes into read-only mode.
Because of such behavior, careful planning must be done to use SSDs in the application environments to ensure that the TBW of the drive is not exceeded before the required life expectancy.
For example, the 25.6 TB 9400 MAX drive has an endurance of 140,160 TB of total bytes written (TBW).
This means that for full operation over five years, write workload must be limited to no more than 76,800 GB of writes per day, which is equivalent to 3.0 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 128,000 GB of writes per day, which is equivalent to 5.0 full drive writes per day.

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

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 table lists the supported operating systems.
Tip: This table is automatically generated based on data from Lenovo ServerProven.
VMware vSAN certification : The drives listed in this product guide are VMware vSAN certified, however in the VMware Compatibility Guide (VCG), they are listed under the drive vendor company name instead of Lenovo. To check a drive for vSAN certification, search the VCG using the Supplier part number as listed in Table 1 in the Part number information section.

Warranty

The 9400 MAX 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.
