Description
Product Overview of the HPE P28335-001
The HPE P28335-001 MegaRAID MR416i-a SAS storage controller is a device that provides hardware RAID (Redundant Array of Independent Disks) functionality to servers, workstations, and other computer systems. The controller is manufactured by Hewlett Packard Enterprise (HPE) and is designed to support a range of SAS (Serial Attached SCSI) and SATA (Serial ATA) drives.
What is a Storage Controller
A storage controller is a device that manages the flow of data between a computer system and a storage device. The controller is responsible for storing and retrieving data from the storage device, as well as managing the performance and reliability of the storage system. Storage controllers can be either hardware-based or software-based.
Hardware-based storage controllers are built into a dedicated device, such as a RAID card or a storage appliance. These controllers typically provide better performance and reliability than software-based controllers, as they have dedicated hardware resources to manage the storage system.
Software-based storage controllers, on the other hand, rely on the processing power of the host system to manage the storage system. These controllers are often used in virtualized environments where dedicated hardware resources are not available.
What is RAID
RAID, or Redundant Array of Independent Disks, is a storage technology that uses multiple hard drives to improve performance, reliability, or both. RAID accomplishes this by combining the storage capacity of multiple disks into a single logical unit, which can be accessed as a single drive.
There are several types of RAID configurations, including RAID 0, RAID 1, RAID 5, and RAID 6. Each configuration has its own benefits and drawbacks, and the choice of RAID configuration will depend on the specific needs of the storage system.
RAID 0 combines the storage capacity of multiple disks into a single logical unit, but does not provide any redundancy. This means that if one disk fails, all data on the RAID 0 volume will be lost.
RAID 1 provides mirroring, where data is written to two disks simultaneously. This provides redundancy, as if one disk fails, the other disk contains a copy of all data on the volume.
RAID 5 combines the storage capacity of multiple disks into a single logical unit and provides parity information, which can be used to reconstruct data in the event of a single disk failure.
RAID 6 is similar to RAID 5, but provides additional redundancy by storing two sets of parity information, which can be used to reconstruct data in the event of two disk failures.
What is SAS
SAS, or Serial Attached SCSI, is a type of storage interface that is used to connect hard drives, solid-state drives, and other storage devices to a computer system. SAS is a successor to the earlier SCSI (Small Computer System Interface) standard and provides faster data transfer rates, improved scalability, and better reliability.
SAS supports both point-to-point and multipoint connections, which allows multiple SAS devices to be connected to a single SAS controller. SAS also provides features such as hot-swapping, which allows drives to be added or removed from a storage system without shutting down the system.
What is MegaRAID MR416i-a SAS Storage Controller?
The HPE P28335-001 MegaRAID MR416i-a SAS storage controller is a hardware-based RAID controller that is designed to provide high-performance and reliable storage for servers and workstations. The controller supports SAS and SATA drives, and provides support for RAID 0, RAID 1, RAID 5, and RAID 6 configurations.
The controller is built on the LSI SAS3108 RAID-on-Chip (ROC) technology, which provides a high-performance, low-latency RAID engine. The controller also includes a 2GB DDR3 cache
