Significance for Server SystemsPerformance Optimization
The combination of a high rotational speed (15000 RPM), SAS interface, and a 6GBPS data transfer rate positions the HP 512547-B21 as a performance-optimized storage solution. In server environments where speed and responsiveness are critical, this hard disk drive excels in meeting the demands of data-intensive applications.
Scalability and Flexibility
The 146GB storage capacity, though modest in comparison to larger drives, provides a balance between performance and capacity. This makes the HP 512547-B21 a scalable solution, allowing organizations to tailor their server configurations based on specific requirements. The flexibility to deploy multiple drives in a RAID configuration further enhances storage capacity and data protection.
Reliability and Redundancy
The dual-port configuration and hot-plug capability contribute to the overall reliability and redundancy of the server system. Redundancy ensures that the failure of one port or drive does not lead to system downtime, and the hot-plug feature allows for seamless replacements or additions, minimizing service disruption and enhancing system availability.
Interface
The HP 512547-B21 uses a Serial-Attached SCSI (SAS) interface, which is a high-speed interface that is commonly used in servers and storage systems. The SAS interface provides a data transfer rate of up to 6 gigabytes per second (GBPS), which is significantly faster than the older SCSI interface.
Dual-Port and Hot-Plug
The HP 512547-B21 is a dual-port drive, which means that it has two SAS ports that can be used for redundancy or load balancing. This allows for improved performance and reliability, as data can be transferred simultaneously over both ports.
The drive is also hot-pluggable, which means that it can be removed and replaced while the server or storage system is still running. This is important for applications that require high levels of uptime and availability, as it allows for maintenance and upgrades to be performed without shutting down the system.
Internal Form Factor
The HP 512547-B21 is an internal hard disk drive, which means that it is designed to be installed inside a server or storage system. The drive has a 2.5-inch form factor, which is smaller than the standard 3.5-inch form factor used in desktop computers.
Compatibility
The HP 512547-B21 is compatible with a wide range of servers and storage systems from Hewlett Packard Enterprise (HP). It is important to ensure that the drive is compatible with your specific system before purchasing it.
Overall, the HP 512547-B21 is a high-performance internal hard disk drive that is designed for use in servers and storage systems. It has a storage capacity of 146 gigabytes (GB), a rotational speed of 15,000 revolutions per minute (RPM), and a Serial-Attached SCSI (SAS) interface with a data transfer rate of up to 6 gigabytes per second (GBPS).
