Lenovo ThinkSystem M.2 ER2 Read Intensive SATA 6Gb SSDs

Product Information

The ThinkSystem M.2 ER2 Read Intensive SATA 6Gb SSDs are high-performance solid-state drives designed for operating system boot purposes and general data storage functions on ThinkSystem servers. These drives are available in capacities of 240GB or 480GB. They are based on the SSSTC ER2 family of solid- state drives and feature 3D TLC NAND flash, end-to-end data protection, thermal throttling/sensor, power loss protection (PLP), high I/O and throughput performance, inrush current management, and compliance with ROHS standards. The SSDs support command sets such as TRIM, S.M.A.R.T, and NCQ.

Product Usage Instructions

To use the ThinkSystem M.2 ER2 Read Intensive SATA 6Gb SSDs, follow these steps:

1. Ensure that your ThinkSystem server is powered off and disconnected from the power source.
2. Locate the M.2 slot on your ThinkSystem server. The M.2 slot is typically located on the motherboard.
3. Insert the M.2 ER2 Read Intensive SATA 6Gb SSD into the M.2 slot, ensuring that it is properly aligned.
4. Tighten any screws or fasteners to secure the SSD in place.
5. Connect the necessary cables, if required.
6. Power on your ThinkSystem server and access the BIOS settings.
7. In the BIOS settings, configure the M.2 SSD as a boot device if you intend to use it as an operating system boot drive.
8. If you plan to use the SSD for general data storage purposes, you may need to initialize and format the drive in your operating system.
9. Once the M.2 ER2 Read Intensive SATA 6Gb SSD is properly installed and configured, you can start using it for your desired applications.

Features

The ThinkSystem M.2 ER2 Read Intensive SATA 6Gb SSDs have the following features:

• Based on the SSSTC ER2 family of solid-state drives
• 3D TLC NAND flash
• End-to-end data protection
• Thermal throttling/sensor
• Power loss protection (PLP)
• High I/O & throughput performance
• Inrush current management
• ROHS-compliant
• Command sets: TRIM, S.M.A.R.T, NCQ

Read Intensive SSDs and Mixed Use SSDs have similar read and write IOPS performance, but the key difference between them is their endurance (or lifetime) — that is, how long they can perform write operations because SSDs have a finite number of program/erase (P/E) cycles. Read Intensive SSDs typically have a better cost per read IOPS ratio but lower endurance and performance compared to Mixed Use SSDs. 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.

For example, the ER2 480GB drive has an endurance of 870 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 477 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 795 GB of writes per day, which is equivalent to 1.7 full drive writes per day.

Warranty

The ER2 M.2 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.
