Description

The lenovo 4xb7a74955 is a high-capacity, capacity-optimized ssd specifically engineered for the thinksystem de ssd series storage arrays. With a substantial 3.84TB capacity and a high-speed 12Gb/s SAS interface, this drive is designed to provide a reliable and efficient storage tier for enterprise-grade workloads. It belongs to the "Read Intensive" category, offering an endurance rating of 1 Drive Write Per Day (DWPD), which makes it an ideal choice for data-intensive applications such as web serving, content delivery, and large-scale data warehousing where data is frequently read but less frequently modified.

This sff hot-swap drive is housed in a 2.5-inch Small Form Factor (SFF) tray, ensuring seamless compatibility with 2U24 enclosures used in systems like the Lenovo DE2000H, DE4000H, and DE6000F. The 12gb sas storage interface ensures a robust data transfer rate of up to 1.2 GBps, significantly reducing latency and preventing bottlenecks in high-performance computing environments. As a genuine Lenovo ThinkSystem component, it integrates fully with the system's management software for real-time health monitoring and simplified maintenance.

Key Features

  • High Storage Density: 3.84TB capacity in a compact 2.5" SFF form factor for maximum rack space efficiency.
  • Enterprise Endurance (1 DWPD): Optimized for read-intensive workloads, providing a balanced lifespan for typical data center operations.
  • 12Gb/s SAS Interface: Offers double the bandwidth of standard SATA drives, supporting full-duplex, bidirectional data paths.
  • Hot-Swap Capability: Allows for immediate replacement or upgrade without needing to power down the storage array.
  • ThinkSystem DE Optimization: Specifically validated for use in DE-Series All-Flash and Hybrid storage arrays.
  • High Performance: Delivers sequential read speeds up to 1,200 MB/s to accelerate data-heavy tasks.

Usage Scenarios

  • All-Flash Arrays (AFA): Use as primary storage in the DE4000F or DE6000F for high-speed database applications.
  • Tiered Storage: Acts as the "Performance Tier" in hybrid systems (DE4000H/DE6000H) to store frequently accessed data.
  • Virtualization: Provides the high IOPS necessary to support multiple Virtual Machines (VMs) without I/O lag.
  • Analytics & Data Lakes: Efficiently handles large-scale data retrieval for real-time business intelligence and reporting.

Frequently Asked Questions

Q1: What does "1DWD" or "1 DWPD" mean?
A1: It stands for "1 Drive Write Per Day." This means you can write the full 3.84TB capacity of the drive once every day for the duration of its warranty period (typically 5 years) without wearing out the flash memory.

Q2: Can I use this drive in a regular ThinkSystem SR server?
A2: No. The 4XB7A74955 is part of the DE Series storage line and uses a specific firmware and tray design intended for DE-Series storage arrays. For SR-series servers, you would need different part numbers like the PM1643a or PM1653 series.

Q3: Is this drive self-encrypting (SED)?
A3: This specific part number (4XB7A74955) is the standard non-FIPS/non-SED model. If you require encryption at the drive level, you should look for the FIPS-certified variant of this capacity.

Q4: How does it compare to 3 DWPD drives?
A4: 3 DWPD drives (Mixed Use) are designed for environments with high write volumes. This 1 DWPD drive is more cost-effective for "Read Intensive" environments where data is written once and read many times.
