Samsung's; Ninth generation; The SATA SSD series (PM893 and PM897) meet almost any application at both capacity and write durability levels. For example, a low PM893 SSD is an ideal choice for high reliability, low power server boot drives. The higher capacity PM893 SSD is applicable to various mainstream read intensive applications, such as collaboration platforms, unstructured data storage, content delivery networks (CDN) and Hyper-converged infrastructure, such as the capacity layer of VMware VSAN nodes. Samsung's PM897 SSD provides higher write durability, making it a mixed read/write workload, such as the ultra converged universal or dedicated cache layer VMware's VSAN, log applications, online Transaction processing and other infrastructure (OLTP), database servers, and other universal servers with legacy workloads. All SSDs in this series use the same Samsung controller and V-NAND flash memory, simplifying customer certification and ensuring reliable high-capacity supply< Br/>
PM897 faces the challenge of storing resources at the lowest total cost when providing reliable computing and services. Data center servers require high-level I/O to maintain CPU utilization performance and high system density to minimize total costs. A storage system that provides I/O performance needs to provide consistent performance and latency for all tenant virtual machines and containers, 365 days a year, 24 hours a day.
Samsung's PM897; SSD includes Enterprise Power Loss Protection (PLP). During normal power failure, the host server allocates time to maintain Data integrity by sending standby commands to each device. If an unexpected power outage occurs, it can cause the cache data in the internal DRAM buffer of the storage device to be lost. This may occur when an unexpected power outage occurs or when the user unplugs the device from the system. However, the PLP architecture of the Samsung PM897 SSD is designed to prevent data loss caused by accidental power outages. After detecting a fault above, the SSD immediately uses the energy stored in the PLP capacitor to provide sufficient time to transfer the cached data in DRAM to flash memory, ensuring that data is not lost.
