Product Overview for the HPE P40473-B21 7.68TB Solid State Drive

In the dynamic realm of enterprise storage solutions, the HPE P40473-B21 emerges as a standout option, offering a robust combination of capacity, speed, and reliability. This guide provides an in-depth exploration of the HPE P40473-B21 7.68 Terabytes (TB) Serial-Attached SCSI (SAS) 24 Gigabytes Per Second (GBPS) 2.5inch Small Form Factor (SFF) Read Intensive Hot Swap Digitally Signed Firmware Solid State Drive (SSD) With Tray. We will delve into its technical specifications, performance capabilities, use cases, and the impact it can have on optimizing storage infrastructure.

Understanding Serial-Attached SCSI Technology

Serial-attached SCSI (SAS) is a high-performance storage interface commonly used in enterprise environments. The HPE P40473-B21 leverages SAS technology to provide a reliable and efficient connection between the SSD and the server or storage controller. With a remarkable speed of 24 Gigabytes Per Second (GBPS), SAS ensures rapid data transfer, making it an ideal choice for demanding enterprise workloads.

Capacity and Small Form Factor

The HPE P40473-B21 boasts an impressive storage capacity of 7.68 Terabytes (TB), catering to the escalating data needs of modern enterprises. The 2.5-inch Small Form Factor (SFF) enhances its compactness, making it suitable for environments with limited physical space. This compact design allows for higher storage density, enabling organizations to maximize their data center resources efficiently.

Read Intensive Design

The term "Read Intensive" indicates the SSD's optimized performance for read-heavy workloads. This specialization is particularly valuable in scenarios where data retrieval speed is crucial. The HPE P40473-B21 excels in read-intensive applications, making it well-suited for tasks such as data warehousing, content delivery, and read-heavy databases.

Hot Swap Capability

One noteworthy feature of the HPE P40473-B21 is its Hot Swap capability, allowing for the replacement of the SSD without shutting down the entire server. This feature significantly reduces downtime during maintenance or upgrades, contributing to enhanced system availability and uninterrupted operations. The convenience of Hot Swap is particularly crucial in mission-critical environments where continuous uptime is a priority.

Digitally Signed Firmware

Firmware integrity is paramount in ensuring the security and stability of storage devices. The HPE P40473-B21 comes equipped with Digitally Signed Firmware, providing a layer of protection against unauthorized modifications. This digital signature verifies the authenticity of the firmware, safeguarding the SSD from potential security threats and ensuring data integrity.

Solid State Drive Advantages

As a Solid State Drive (SSD), the HPE P40473-B21 inherits the advantages associated with this modern storage technology:

  • Speed and Performance: SSDs, by nature, offer faster data access times compared to traditional Hard Disk Drives (HDDs). The 24 GBPS speed of the HPE P40473-B21 SAS SSD ensures rapid data transfer, reducing latency and improving overall system responsiveness.
  • Reliability and Durability: SSDs have no moving parts, mitigating the risk of mechanical failures that can occur in HDDs. The absence of moving components enhances reliability and durability, making the HPE P40473-B21 well-suited for demanding enterprise environments.
  • Energy Efficiency: SSDs generally consume less power than HDDs, contributing to energy efficiency in data centers. The reduced power consumption of the HPE P40473-B21 can lead to lower operational costs over time.
  • Noise Reduction: Since SSDs lack spinning disks and mechanical components, they operate silently. In noise-sensitive environments, such as offices or data centers with proximity to working spaces, the quiet operation of the HPE P40473-B21 can be advantageous.
Use Cases

The versatile design of the HPE P40473-B21 makes it suitable for various enterprise use cases. Here are some scenarios where this SAS SSD can demonstrate its prowess:

  • Data Warehousing: In data warehousing environments where large volumes of data need to be quickly retrieved for analysis, the HPE P40473-B21's high sequential read speeds and read-intensive design offer optimal performance.
  • Content Delivery Networks (CDN): Content delivery networks often require rapid data access for delivering media content. The HPE P40473-B21's read-intensive capabilities make it well-suited for CDN applications, ensuring smooth content delivery to end-users.
  • Business Intelligence (BI) Applications: BI applications often involve complex queries and analytics, demanding high-speed data access. The HPE P40473-B21's performance characteristics make it an ideal choice for accelerating BI workloads.
  • Virtualization Infrastructure: In virtualized environments where multiple virtual machines coexist, the HPE P40473-B21's read-intensive design and high IOPS contribute to responsive and efficient virtual machine operations.
Reliability and Durability

Reliability is a critical factor in enterprise storage solutions, where system downtime can have severe repercussions. The HPE P40473-B21, with its solid-state design and advanced features, enhances overall system reliability. The absence of moving parts reduces the risk of mechanical failures, ensuring continuous operation in mission-critical environments.

Security Features

Data security is a top priority in enterprise settings, and the HPE P40473-B21 incorporates advanced security features to address these concerns. The inclusion of Digitally Signed Firmware adds an additional layer of protection, preventing unauthorized modifications to the SSD's firmware. This security measure safeguards the integrity of stored data, addressing potential vulnerabilities in the storage infrastructure.


While performance and reliability are crucial considerations, cost-effectiveness remains a significant factor for enterprises. The HPE P40473-B21 strikes a balance between high-performance storage and cost-efficiency, offering a competitive solution for organizations seeking to enhance their storage infrastructure without exceeding budget constraints. The long-term durability of SSDs contributes to a lower total cost of ownership over the product's lifespan.
