The SAS (Serial Attached SCSI) interface is a high-speed data storage interface that uses a serial protocol to transfer data between computer systems and storage devices, such as hard drives and solid-state drives. The interface allows for faster data transfer rates and more reliable connections than older parallel SCSI interfaces.
Data transfer rate is the amount of data that can be moved from one place to another in a given amount of time. In the case of hard drives, it is measured in bytes per second. The data transfer rate for the 857646-B21 HPE 10TB 7.2K RPM SAS 12GBPS Midline LFF Hard Drive is 12 Gbps, which means that it can transfer data at a maximum rate of 12 gigabits per second. This is a high data transfer rate, which makes it suitable for use in high-performance storage systems and data centers.
Power consumption and environmentalPower consumption refers to the amount of electrical power required for a device or system to operate. Environmental specifications refer to the conditions under which a device or system is designed to operate, such as temperature and humidity ranges.
The 857646-B21 HPE 10TB 7.2K RPM SAS 12GBPS Midline LFF Hard Drive has a power consumption rating of 9.5 watts when active and 5.8 watts when idle. This is considered to be a relatively low power consumption for a hard drive of this capacity and performance.
The environmental specifications for this hard drive include operating temperatures between 41°F and 131°F (5°C and 55°C), and non-operating temperatures between -40°F and 158°F (-40°C and 70°C). It also has a relative humidity range of 8% to 90% (non-condensing). This means that the hard drive is designed to operate within these temperature and humidity ranges, and may not perform correctly or may be damaged if operated outside of these limits.
Compatibility with HPE servers and storage arraysCompatibility refers to the ability of a device or system to work with other devices or systems. In the case of the 857646-B21 HPE 10TB 7.2K RPM SAS 12GBPS Midline LFF Hard Drive, compatibility refers to its ability to work with HPE servers and storage arrays.
This hard drive is specifically designed to be compatible with HPE servers and storage arrays that use a SAS interface and support the LFF form factor. It should be compatible with a wide range of HPE ProLiant servers and storage arrays, including those that support 12 Gbps SAS technology. The compatibility list can be found in the HPE website, it is important to check the compatibility before purchasing this hard drive.
It is recommended to check the documentation of the specific HPE server or storage array that the hard drive will be used with to ensure that it supports the 857646-B21 model and that it meets the necessary technical specifications.
