The HPE P40471-K21 SAS 24GBPS 1.92TB Read Intensive SFF Basic Carrier SSD has several features to ensure data protection and data recovery in case of power failure or other types of failures.
- Power Loss Data Protection (PLDP): PLDP is a technology that protects data in case of sudden power loss or a power outage. It writes data to non-volatile memory (NVRAM) before shutting down, allowing the SSD to resume normal operations once power is restored.
- Uncorrectable Bit Error Rate (UBER): UBER is a measure of the reliability of an SSD. A UBER of less than 1 sector per 10^17 bits read is considered acceptable for enterprise-class SSDs, and the HPE P40471-K21 meets this requirement.
- RAID Configuration: By using RAID (Redundant Array of Inexpensive Disks) configurations, such as RAID 5 or RAID 6, data can be protected against drive failure and improve the reliability of the storage system.
- Error Correction Code (ECC): ECC is a method of detecting and correcting errors in the data stored on an SSD. The HPE P40471-K21 uses ECC to ensure the integrity of data stored on the drive.
- Hot Spare Support: The HPE P40471-K21 supports hot spare functionality, which allows for a spare drive to be available in case of drive failure. This helps to minimize downtime and improve data recovery.
In the event of a failure, data recovery can be performed using various methods, including using backup and restore, data recovery software, or professional data recovery services. It is always recommended to regularly backup important data to minimize the risk of data loss in case of failures.
High-Performance ComputingThe HPE P40471-K21 SAS 24Gbps 1.92TB Read Intensive SFF Basic Carrier SSD is a solid-state drive (SSD) that provides high-performance computing capabilities. The drive has a read-intensive workload optimized design and is capable of delivering 24 Gbps of data transfer speed through its SAS interface. With a capacity of 1.92TB, it provides ample storage space for storing large amounts of data.
This SSD is designed to be used in a high-performance computing environment and is well-suited for applications that require fast, reliable data access. The read-intensive design of the drive provides fast read speeds, making it ideal for use cases where data retrieval is a key requirement. Additionally, the SAS interface allows for easy integration with other SAS-based components, providing a high-speed, low-latency data transfer path.
The HPE P40471-K21 SAS 24Gbps 1.92TB Read Intensive SFF Basic Carrier SSD is a small form-factor (SFF) drive, which makes it an ideal choice for use in space-constrained systems. The Basic Carrier form factor allows for easy integration with other basic carrier components, making it an ideal choice for a wide range of applications and systems.
Latency and Response TimeThe latency and response time of the HPE P40471-K21 SAS 24GBPS 1.92TB Read Intensive SFF Basic Carrier SSD are important factors that determine its performance and speed.
Latency refers to the time it takes for a command to be received and processed by the SSD, and for the first data to start being transferred. Latency can be influenced by several factors, including the type of interface (SAS, SATA, NVMe), the speed of the interface, the architecture of the SSD, and the workload.
Response time refers to the total time it takes for a command to be received, processed, and for all requested data to be transferred. Response time is influenced by factors such as queue depth, random vs sequential access patterns, and the size of the request.
The exact latency and response time of the HPE P40471-K21 SAS 24GBPS 1.92TB Read Intensive SFF Basic Carrier SSD can vary depending on the specific workload and environment, but generally speaking, SAS SSDs tend to have lower latency and faster response times compared to SATA SSDs. Additionally, the HPE P40471-K21 is a read-intensive SSD, meaning it is optimized for read-heavy workloads, which can result in lower response times for read operations.
