Introduction
The SAS MLC Enterprise solid-state drives (SSDs) for System x® employ MLC NAND technology to provide an affordable, but performance-driven solution for applications requiring enterprise workloads with a mix of read/write operations. These industry standard 2.5-inch and 3.5-inch form factor SSDs use a single-chip controller with a SAS interface on the system side and 16 channels of NAND flash internally. They provide outstanding performance, endurance, reliability, and energy efficiency for random read- and write-intensive enterprise workloads such as databases, data warehouses, corporate email and collaboration, actively connected users, caching and tiering applications, and others.

Did you know?
With SanDisk FlashGuard protection, SAS MLC Enterprise SSDs can be fully rewritten up to ten times per day throughout their entire five-year life expectancy. Unlike SATA drives, the SAS interface supports full duplex data transfer for higher performance, as well as dual port connectivity and enterprise-level error recovery for better availability.

Rigorous testing of SAS Enterprise MLC SSDs by Lenovo through the ServerProven® program assures a high degree of confidence in storage subsystem compatibility and reliability.

• One SSD with either a hot-swap or simple-swap tray, depending on the part number
• Technical Update Flyer
• Warranty Flyer
• Important Notices document

Features
The SAS MLC Enterprise SSDs have the following features:Industry standard 2.5-inch or 3.5-inch drive form factor

• Utilizes 19 nm MLC NAND technology
• Cost-effective MLC SAS drive with high read and write performance to fulfill client needs in the enterprise space
• High endurance, with up to 29.2 PB of total bytes written (TBW) to withstand applications with intensive read/write workloads
• Energy saving, with as little as 7 watt power consumption per drive
• Absence of moving parts to reduce potential failure points in the server
• S.M.A.R.T. support
• Advanced Encrypting Standard (AES) 256-bit encryption
• FlashGuard technology extends the native endurance of commercial-grade MLC flash
  • Aggregated Flash Management
  • Advanced Signal Processing
  • Enhanced Error Correction
• DataGuard technology protects against data corruption and loss
  • Full data path protection
  • Flexible Redundant Array of Memory Elements (F.R.A.M.E.) data recovery algorithm
• EverGuard technology protects data in the event of unplanned power outages
• Static wear leveling evenly distributes data across the drive
• Bad block management replaces failed blocks with new ones from the spare pool
• Thermal throttling to extend the life of the drive
• Data retention management to ensure availability and integrity of stored data
• Minimal write amplification for efficient flash utilization and extended lifetime

The key difference between Enterprise SSDs such as the SAS MLC Enterprise SSDs and other SSDs is their endurance (or life expectancy). SSDs have a huge but finite number of program/erase (P/E) cycles, which affects how long they can perform write operations and thus their life expectancy. Enterprise SSDs have significantly better endurance but higher cost/IOPS ratio compared to Enterprise Value SSDs. SSD write endurance is typically measured by the number of program/erase cycles that the drive can incur over its lifetime, listed as TBW in the device specification.

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 will not fail upon reaching the specified TBW, but at some point after surpassing the TBW value (and based on manufacturing variance margins), the drive will reach the end-of-life point, at which time the drive will go 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 will not be exceeded prior to the required life expectancy.
