More Information on the HPE 846434-B21 SSD
The 846434-B21 is a solid-state drive (SSD) made by Hewlett Packard Enterprise (HPE). It is designed to be used in servers and offers high-speed data transfer rates with a capacity of 800 gigabytes (GB). This drive is based on the Serial-Attached SCSI (SAS) 12 Gigabits per second (GBPS) interface, which offers faster data transfer rates than the traditional SATA interface. The drive is also hot-swappable and has a small form factor (SFF) of 2.5 inches, making it ideal for use in servers where space is at a premium.
Understanding the Basics HPE 846434-B21
- Small Form Factor (SFF): The HPE 846434-B21 comes in a Small Form Factor, ensuring it can seamlessly integrate into servers without occupying excessive space. This compact design contributes to efficient server configurations, allowing for optimal use of available resources.
- Serial-Attached SCSI (SAS): The Serial-Attached SCSI interface is a key component of the HPE 846434-B21, providing a high-speed, point-to-point data transfer protocol. With a 12 Gigabits Per Second (GBPS) data transfer rate, this SAS SSD ensures swift and reliable communication between the drive and the server.
- Impressive Storage Capacity: At the heart of the HPE 846434-B21 lies an impressive storage capacity of 800GB. This ample space is well-suited for a variety of server applications, from hosting databases to supporting virtualized environments.
- Mixed-Use Capability: One of the standout features of the HPE 846434-B21 is its Mixed-Use designation. This means the SSD is optimized for workloads that demand both read and write operations, making it versatile for a broad range of applications. Whether it’s handling transactional databases or supporting virtualization, the mixed-use capability ensures consistent and reliable performance.
- Hot Swap Functionality: The concept of hot-swapping drives has become integral in modern server architectures. The HPE 846434-B21 embraces this trend with its Hot Swap functionality. This feature allows administrators to replace or add drives without shutting down the server, minimizing downtime and enhancing overall system availability.
Serial-Attached SCSI (SAS)
- The Serial-Attached SCSI (SAS) interface is a type of interface used in servers and storage devices. It is a high-speed interface that offers faster data transfer rates than the traditional SATA interface. The SAS interface is based on a point-to-point architecture, which means that each device is connected directly to the host. This allows for faster data transfer rates, as each device can communicate directly with the host without any bottlenecks.
- SAS also offers other advantages over SATA, including better error detection and correction, higher scalability, and support for multiple host connections. This makes SAS an ideal choice for high-performance servers and storage devices.
12 Gigabits per second (GBPS)
- The 846434-B21 SSD is based on the SAS 12 Gigabits per second (GBPS) interface, which offers faster data transfer rates than the previous generation SAS 6 GBPS interface. This means that data can be transferred to and from the drive at a rate of up to 12 gigabits per second, which translates to a maximum transfer rate of 1.5 gigabytes per second.
- The faster data transfer rates offered by SAS 12 GBPS make it an ideal choice for high-performance servers and storage devices, where fast access to data is critical.
800 Gigabytes (GB) Capacity
- The 846434-B21 SSD has a capacity of 800 gigabytes (GB), which is a relatively large amount of storage for a small form factor (SFF) drive. This makes it an ideal choice for use in servers and storage devices where space is at a premium.
- The large capacity of the drive also means that it can store a large amount of data, which is important for applications that require a lot of storage space, such as databases, virtual machines, and media files.
Mixed Use
The 846434-B21 SSD is a mixed-use drive, which means that it is designed to handle both read-intensive and write-intensive workloads. This makes it an ideal choice for applications that require a balance between read and write performance, such as databases, virtualization, and analytics.
Hot Swap
- The 846434-B21 SSD is hot-swappable, which means that it can be replaced while the server is still running. This is important for mission-critical applications that require maximum uptime, as it allows for easy replacement of faulty drives without having to shut down the server.
- Hot-swapping also allows for easy upgrades, as drives can be replaced with larger-capacity drives without having to shut down the server or disrupt operations.
Small Form Factor (SFF)
- The 846434-B21 SSD has a small form factor (SFF) of 2.5 inches, which makes it ideal for use in servers where space is at a premium. The small form factor allows for more drives to be installed on the server, which increases the storage capacity of the server.
- The small form factor also means that the drive consumes less power and generates less heat, which is important for server environments where power and cooling are critical.
