- The HPE P440 4GB 1 Port PCI-E SAS/SATA FBWC Smart Array Storage Controller, with part number 726821-B21, is a RAID controller designed for use in Hewlett Packard Enterprise (HPE) servers.
- The controller comes with 4GB of memory, which is used to cache data and improve performance. It also has a single PCIE interface, which is a high-speed expansion interface that connects the controller to the server's motherboard. This interface is capable of providing high-speed data transfer between the controller and the server.
- The controller supports both SAS and SATA drives, which means that it can be used to control a variety of storage devices, including hard disk drives (HDDs) and solid-state drives (SSDs). SAS and SATA are both types of interfaces used to connect storage devices to a computer. SAS (Serial Attached SCSI) is typically used for enterprise-level storage systems and provides faster data transfer rates and improved reliability compared to SATA. SATA (Serial ATA) is more commonly used in consumer-level systems and provides slower data transfer rates but is more widely supported.
- FBWC stands for "Flash-backed write cache," which is a feature that uses a small amount of flash memory as a write cache to improve performance. The flash memory is used to temporarily store data before it is written to the storage devices. This can significantly improve write performance, especially when the storage devices are slow or have high latency.
- Smart Array is the brand name of HPE's line of RAID controllers. RAID (Redundant Array of Inexpensive Disks) is a technology that allows multiple physical disks to be combined into a single logical volume, providing increased performance and data protection. The P440 is a high-performance RAID controller that is designed for use in enterprise environments where high availability and data protection are critical.
- The HPE P440 4GB 1 Port PCI-E SAS/SATA FBWC Smart Array Storage Controller is a high-performance RAID controller that is designed for use in enterprise environments. It comes with 4GB of memory, a single PCIE interface, and supports both SAS and SATA drives. It also has a flash-backed write cache feature that can significantly improve write performance.
- The HPE P440 4GB 1 Port PCI-E SAS/SATA FBWC Smart Array Storage Controller (part number 726821-B21) supports a variety of RAID levels, which provide different levels of data protection and performance. The specific RAID levels supported may vary depending on the configuration and the number of physical disks connected to the controller.
- Typically, the P440 controller supports RAID 0, RAID 1, RAID 1+0, RAID 5, RAID 6, and RAID 60.
- RAID 0, also known as striping, improves performance by dividing the data across multiple physical disks. However, it does not provide any data protection, so if one disk fails, all data is lost.
- RAID 1, also known as mirroring, creates an exact copy of the data on two or more physical disks. This provides complete data protection in case one disk fails, but does not improve performance.
- RAID 1+0, also known as mirroring and striping, combines the benefits of RAID 0 and RAID 1. It provides both improved performance and complete data protection.
- RAID 5 and RAID 6, also known as striping with parity, use a parity scheme to protect data in case one disk fails. RAID 5 uses a single parity block and RAID 6 uses dual parity blocks, which improves the fault tolerance.
- RAID 60, also known as double parity RAID 6, adds another level of protection by using both striping and dual parity on multiple RAID 6 sets. This provides very high data protection against multiple disk failures.
- The HPE P440 4GB 1 Port PCI-E SAS/SATA FBWC Smart Array Storage Controller (part number 726821-B21) is designed for use in Hewlett Packard Enterprise (HPE) servers. It is specifically designed to work with HPE ProLiant servers, and it may also be compatible with other HPE server models.
- As it is a Smart Array Controller, it is compatible with HPE's software management tools and utilities, such as HPE Smart Storage Administrator, HPE Systems Insight Manager, and HPE Integrated Lights-Out. These tools and utilities provide advanced monitoring, management, and configuration capabilities for the controller and the storage devices.
- Regarding interoperability, the P440 controller supports various operating systems, including Microsoft Windows, Linux, and VMware. It also supports different types of storage devices, including SAS and SATA hard disk drives (HDDs) and solid-state drives (SSDs). However, the specific operating systems and storage devices supported may vary depending on the configuration and the firmware version of the controller.
