The Lenovo 120 GB, 240 GB, 480 GB, and 800 GB solid-state drives (SSDs) are next-generation Enterprise Value SSDs for System x that are engineered for greater performance and endurance in a cost-effective design, and to support a broader set of workloads. These SSDs are available as 2.5-inch form factor drives with both simple-swap (SS) and hot-swap (HS) options, as well as 3.5-inch hot-swap and 1.8-inch drives.
The Lenovo Serial Advanced Technology Attachment (SATA) MLC Enterprise Value SSDs have the following features:
1.8-inch, 2.5-inch, and 3.5-inch industry standard form factors
Support for a conventional 2.5-inch or 3.5-inch drive bay (2.5-inch or 3.5-inch SSDs, respectively) or eXFlash SSD drive bay or SSD drive bay on selected iDataPlex®, BladeCenter®, Flex System™, and NeXtScale System servers (1.8-inch drives)
6 Gbps SATA interface
Use of industry-leading Micron 20 nm MLC NAND technology
Cost-effective MLC NAND technology with high read and write performance:
Up to 65,000 read IOPS
Up to 35,000 write IOPS
Up to 425 MBps sequential read rate
Up to 375 MBps sequential write rate
Enterprise Data Path Protection to ensure NAND integrity
Static and dynamic wear leveling
Endurance: up to 1.9 PB of total bytes written (TBW) for an 800 GB drive
Support for MegaRAID CacheCade feature of a supported ServeRAID controller
Energy-saving 6 watt typical power consumption per drive
Absence of moving parts reduces potential failure points in the server
Native command queuing support
Self-monitoring, analysis, and reporting technology (SMART) command set
Enterprise Value SSDs and Enterprise 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). Enterprise Value SSDs have a better cost/IOPS ratio but lower endurance compared to Enterprise SSDs. SSD write endurance is typically measured by the number of program/erase (P/E) cycles that the drive incurs over its lifetime, listed as the total bytes of written data (TBW) in the device specification.
