Introduction

The Lenovo PM1635 Enterprise Mainstream 12Gb SAS solid-state drives (SSDs) in capacities of 400 GB, 800 GB and 1.6 TB capacity are next-generation high-performance SSDs suitable for a wide range of applications of running on both System x and ThinkServer platforms.

Did you know?

Unlike SATA drives, the 12 Gb/s SAS interface on these drives supports full duplex data transfer for higher performance, as well as dual port connectivity and enterprise-level error recovery for better availability. By combining the enhanced reliability of Samsung NAND flash memory silicon with NAND Flash management technologies, PM1635 SSDs deliver the extended endurance of up to 3 drive writes per day (DWPD) for 5 years, which is suitable for many enterprise applications.

Features

The PM1635 Enterprise Mainstream SSDs have the following features:

  • Mainstream server SSD suitable for mixed read-write-intensive workloads
  • Endurance of 3 drive-writes per day (DWPD)
  • 2.5-inch or 3.5-inch industry standard form factor with hot-swap tray
  • SAS 12 Gbps interface
  • Active-active dual port host interface
  • Protect data integrity from unexpected power loss with Samsung's advanced power-loss protection architecture
  • Supports Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T)
  • End-to-end data protection
  • Support 16 Initiator with Tag Command Queuing (TCQ) Command Set with a queue-depth of up to 128 commands
  • Compliant with SCSI Specification (SAS-3 / SPL-3 / SBC-4 / SPC-4 / SAM-5)
  • RoHS Compliant

Enterprise Entry SSDs and Enterprise Mainstream 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 Mainstream SSDs have better endurance but lower cost/IOPS ratio compared to Enterprise Entry 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.

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.

Because of such behavior by Enterprise Entry solid-state drives, careful planning must be done to use them only in read-intensive or mixed up to 70% read/30% write environments to ensure that the TBW of the drive will not be exceeded before the required life expectancy.

For example, the 1.6TB Enterprise Mainstream 12Gb SAS G3HS 2.5" SSD has an endurance of 8,760 TB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 4.8 TB of writes per day, which is equivalent to 3 full drive writes per day (DWPD). For the device to last three years, the drive write workload must be limited to no more than 8 TB of writes per day, which is equivalent to 5 full drive writes per day.

Warranty

The PM1635 Enterprise Mainstream 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.
