Introduction

The ThinkSystem PM1643 Capacity SAS 12Gb solid-state drives (SSDs) are next-generation high-capacity SSDs suitable for a wide range of applications. The PM1643 Capacity SAS SSDs are designed for dense storage and with a 12 Gb SAS interface, these drives feature all the capacity and performance that is needed to replace large numbers of 15K rpm and 10K rpm spinning disks, and consolidate storage into tightly packed server configurations.

The PM1643 SSDs are the follow-on to the PM1633a SSDs and offer significantly improved performance, both for random and sequential workloads.

Did you know?

Capacity SSDs are a category of cost-effective high-capacity SSDs where it makes sense to store all of your data on the SSDs, and not use the SSDs only for caching or indexes. 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.

Features

The ThinkSystem PM1643 Capacity SAS SSDs have the following features:

  • High capacity server SSD suitable for read-intensive workloads
  • Based on Samsung 64-layer V-NAND technology and TLC flash memory
  • Endurance of 1 drive-write per day (DWPD) over 5 years
  • 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 Capacity SSDs have similar read and write IOPS performance and similar endurance to Entry SSDs, however, the key difference is density - the total amount of storage in each 2.5-inch drive. With large configurations, more storage can be installed internal to the server, changing the need for external JBOD connections thereby saving power and rack space.

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.

For example, the 3.84 TB PM1643 drive has an endurance of 7 PB of total bytes written (TBW). This means that for full operation over five years, write workload must be limited to no more than 3,840 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 6,400 GB of writes per day, which is equivalent to 1.7 full drive writes per day.

Operating system support

SSDs operate transparently to users, storage systems, applications, databases, and operating systems.

Operating system support is based on the controller used to connect to the drives. Consult the controller propduct guide for more information:

Warranty

The PM1643 Capacity SAS 12Gb SSDs carry a one-year, customer-replaceable unit (CRU) limited warranty. When the SSDs are installed in a supported server, these drives assume the server’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.
