The 846436-B21 ProLiant Gen8 is an internal solid-state drive (SSD) designed for servers. This device is manufactured by Hewlett Packard Enterprise (HPE) and boasts a storage capacity of 1.6 terabytes (TB). It is equipped with Serial Attached SCSI (SAS) technology that supports data transfer rates of up to 12 gigabytes per second (GBPS). In addition, the drive features Hot Swap capabilities, Mixed Use Multi-Level Cell (MLC) technology, and a 2.5-inch Small Form Factor (SFF) Smart Carrier design. In this article, we will delve deeper into the features of the 846436-B21 ProLiant Gen8 SSD.
Serial Attached SCSI (SAS) Technology- The 846436-B21 ProLiant Gen8 SSD utilizes SAS technology, which is a communication protocol used to transfer data between computer components. SAS is an evolution of the SCSI (Small Computer System Interface) protocol and provides a high-speed, point-to-point interface for connecting storage devices to servers. This technology is known for its reliability, scalability, and backward compatibility with older SCSI devices.
- SAS supports data transfer rates of up to 12 gigabytes per second (GBPS), which is faster than most other storage interfaces. This high-speed connectivity allows for faster data transfer, which is crucial for applications that require high-speed processing and data access. Furthermore, SAS technology supports the use of multiple drives in a single array, providing increased storage capacity and redundancy.
The 846436-B21 ProLiant Gen8 SSD features Hot Swap capabilities, which allow the drive to be replaced or added to a server without shutting down the system. This feature enables IT administrators to perform maintenance tasks without disrupting operations, improving system availability and reducing downtime. Hot Swap capabilities also make it easier to upgrade storage capacity or replace faulty drives, resulting in better system performance and data reliability.
Mixed Use Multi-Level Cell (MLC) TechnologyThe 846436-B21 ProLiant Gen8 SSD utilizes Mixed Use Multi-Level Cell (MLC) technology, which is a type of NAND flash memory that offers a balance between performance, endurance, and cost. MLC technology stores multiple bits of data per memory cell, allowing for higher storage densities and lower costs compared to other types of flash memory. Mixed Use MLC technology is ideal for applications that require a balance between read/write performance and endurance, such as online transaction processing, virtualization, and analytics. This technology provides higher endurance than Consumer MLC (cMLC) SSDs, which are designed for lower-duty workloads but may not offer the same level of performance as Single-Level Cell (SLC) or Enterprise MLC (eMLC) SSDs, which are designed for high-duty workloads.
2.5-inch Small Form Factor (SFF) Smart Carrier DesignThe 846436-B21 ProLiant Gen8 SSD features a 2.5-inch Small Form Factor (SFF) Smart Carrier design. SFF drives are smaller than traditional 3.5-inch drives, allowing for higher storage densities in servers and other storage systems. The Smart Carrier design allows for easy installation and maintenance of the drive, as well as providing better cooling and power efficiency. The Smart Carrier also provides integrated sensors that monitor the temperature, humidity, and other environmental factors within the server. This information can be used to optimize cooling and power usage, and to alert IT administrators to potential issues before they cause downtime.
