Samsung PM1725a NVMe SSD | Exceptionally Fast Speeds and Low Latency for Enterprise Applications

Maximize Data Transfer with the High-performance, Reliable PM1725a

Enterprise environments have unique requirements to ensure that they operate optimally 24/7, 365 days a year. A varied level of performance with low latency is essential. It is also critical that these environments remain stable when processing various read and write workloads. And the most crucial criteria of all are protection from data corruption or loss due to unexpected power outages. Considering each of these factors, IT and data center managers are tasked with finding high performing, dependable memory solutions.

Samsung is well-equipped to offer superb enterprise environment SSDs. The drives deliver exceptional performance in multithread applications, such as compute and virtualization, relational databases, and storage. These high-performing SSDs also provide outstanding reliability for continual operation regardless of unanticipated power loss. Their reliability also extends to non-interrupt service in case a failure occurs on one of the paths to a port.

Using its proven expertise and wealth of experience in cutting-edge SSD technology, Samsung memory solutions helps data centers operate continually at the highest performance levels.

Samsung has the added advantage of being the sole manufacturer of all of its SSD components. This advantage helps ensure end-to-end integration, quality assurance and the utmost compatibility.

Samsung PM1725a NVMe SSD Delivers

Exceptional value: The PM1725a utilizes Samsung V-NAND flash memory, which features a unique design that stacks 48 layers on top of another. It also employs cost-effective TLC (triple-level cell) flash memory, which delivers higher reliability than MLC (multi-level cell) planar NAND flash memory SSDs. With this architecture, the PM1725a can deliver enterprise-level performance economically.

Consistently high performance: The PM1725a HHHL (half-height, half-length) card delivers a wide bandwidth of up to 6,200/2,600 MB/s sequential R/W speeds respectively, using under 23 W of power. It delivers up to 1,000K and 180K IOPS for random 4KB read and write, respectively. The PM1725a 2.5-inch SSD delivers a bandwidth of up to 3,300/3,000 MB/s for sequential R/W and up to 800K/160K IOPS for random 4KB R/W, respectively. The PM1725a delivers QoS (quality of service, 99%) of 160µs and 100µs for random 4KB writes.

Outstanding reliability: Even though the PM1725a employs a TLC V-NAND flash memory, it boasts 5 DWPD (drive writes per day) for 5 years. This rate translates to writing a total of 32 TB each day during that time, which means users can write 6,400 files of 5 GB-equivalent data every day. This level of reliability is more than sufficient for enterprise storage systems that have to perform ultrafast transmissions of large amounts of data.

High density: By fitting more memory into a V-NAND chip, it provides significantly more capacity of up to 6.4 TB in PM1725a HHHL card SSDs.

Optimized for Enterprise Environments

The Samsung PM1725a SSD is optimized to excel in virtually any data center scenario. This enterprise-level, ultra-high performance SSD provides unsurpassed random read performance and is particularly suitable for read-intensive data center applications. When compared with other standardized Samsung SSDs, the PM1725a SSD provides the highest random read IOPS performance.

The PM1725a is equipped with Samsung 3rd-generation TLC V-NAND technology. This technology eliminates performance and reliability issues that result from capacity limitations found in planar NAND technologies. Samsung V-NAND technology delivers reliable and consistent performance at lower costs for today's demanding data-centric world.

Superb Performance Over SAS SSDs

The PM1725a uses a state-of-the-art NVMe interface to overcome bottlenecks experienced in SAS (serial-attached SCSI) and SATA interfaces. Furthermore, the PM1725a employs the highest density to successfully process intensive and heavy enterprise workloads.

The figures below compare the performance of a Samsung enterprise SAS SSD, which uses MLC V-NAND flash memory, with the TLC-based PM1725a. With comparable cost, the PM1725a provides up to 4.3 times more bandwidth than the MLC-based SAS SSD for sequential read and up to 5 times more IOPS for 4 KB random read.

SR-IOV Support

SR-IOV (single-root I/O virtualization) is a PCI-SIG® specification for I/O virtualization. It provides a standard mechanism for devices to advertise their ability to be simultaneously shared among multiple VMs (virtual machines).

It also allows for the partitioning of a PCI® function into many virtual interfaces for the purpose of sharing the resources of a PCIe device in a virtual environment. PM1725a drives support SR-IOV, which enables the efficient sharing of PCIe devices among virtual machines running on the same host. Hypervisor overhead is reduced by providing an independent, direct I/O path between VMs and devices. The PM1725a can attain its maximum random read performance, even in a virtualized environment, using SR-IOV. Also the direct I/O path between VMs and devices eliminates hypervisor bottlenecks, as illustrated in the figure below.

Multi-namespace Support

The PM1725a supports multiple namespaces, where a single SSD can be partitioned into multiple hardware partitions. A namespace can be assigned to multiple hosts or dedicated to a single host. The PM1725a supports up to 32 multiple namespaces.

Enterprise-grade Power-loss Protection

During normal power-off periods, the host server allocates time to maintain data integrity by transmitting standby commands to each device. In the event of an unexpected power loss, though, the SSD immediately uses the stored energy from tantalum capacitors to provide enough time to transfer the cached data in DRAM to the flash memory. This process helps ensure no loss of data.

Power loss can occur with power outages or when users unplug devices from the system. However, the PM1725a NVMe SSD has been designed to prevent data loss with its PLP (power-loss protection) architecture. In the event of sudden power off or power failure, the PLP solution can help ensure that data issued by the host system is written to the storage media to reduce the risk of loss of data.

Built-in Self-encryption Features

The PM1725a protects data with AES 256-bit hardware-based encryption without the performance degradation often experienced with software-based encryption.

Remote Health Monitoring

The PM1725a provides a remote health-monitoring feature by the Samsung SSD Toolkit. The Samsung SSD Toolkit is proprietary software designed to help users with easy-to-use SSD management and diagnostic features for server and data center usage.

The CLI (command line interface) tool currently supports Samsung data center and enterprise NVMe SSDs and supports Linux®.

Features include:

• Health monitoring: Provides vital drive status information and supports users to update firmware, measure drive performance, initialize drives, calculate drive lifetime and more.
   
• Remote health monitoring for FA (failure analysis): Provides a smart way for resolving field issues by the remote health monitoring feature. This way of issue handling reduces turnaround time compared to the traditional way of handling the issue, such as dispatching an engineer, and provides quicker resolution. The customer can get the initial resolution in two steps: first by running the SSD Toolkit and second by sending the debug information back to Samsung and getting the resolution effectively.

"MyDigitalDiscount has a batch of the 6.4TB model that they're selling for just 19 cents/GB - less than many high-end consumer NVMe drives." "Despite its age, the 6.4TB Samsung PM1725a is by several metrics the fastest SSD we have ever tested, and one of only two drives in our collection that can hit more than 1 million IOPS for 4kB random reads."
