Description
Product overview of the Dell Perc H800 PCI-Express SAS Raid Controller
The Dell Perc H800 PCI-Express SAS Raid Controller is a piece of hardware designed for use in servers and workstations. It is used to manage hard disk drives (HDDs) and solid-state drives (SSDs) in a storage array configuration, providing data redundancy and increased system performance. The H800 controller is part of the Dell PowerEdge RAID Controller (PERC) product line and is designed specifically for use with Dell PowerEdge servers.
SAS
SAS stands for Serial Attached SCSI, which is a type of interface used to connect storage devices to a computer. SAS is faster and more reliable than its predecessor, SCSI, and is commonly used in server environments where reliability and performance are critical.
A RAID Controller
A RAID controller is a device that manages multiple hard drives or solid-state drives to provide data redundancy and increased system performance. RAID stands for Redundant Array of Independent Disks, and it is a method of combining multiple storage devices into a single logical unit. RAID can provide increased performance by distributing data across multiple drives, and it can provide data redundancy by storing multiple copies of data across multiple drives.
Features of the Dell Perc H800
The Dell Perc H800 is a high-performance RAID controller that is designed to provide data redundancy and increased system performance. Some of the key features of the H800 include:
- PCI-Express Interface: The H800 connects to the server or workstation via a PCI-Express interface, which provides high-speed data transfer rates and low latency.
- SAS Connectivity: The H800 supports SAS connectivity, which provides faster data transfer rates than SATA connectivity.
- RAID Support: The H800 supports RAID levels 0, 1, 5, 6, 10, 50, and 60, which provide varying levels of data redundancy and increased system performance.
- Cache Memory: The H800 has 512MB of cache memory, which can improve system performance by caching frequently accessed data.
- Battery Backup Unit: The H800 has an optional battery backup unit (BBU) that provides backup power to the cache memory in the event of a power failure. This ensures that data in the cache is not lost and can be written to disk when power is restored.
- Hot-Swap Support: The H800 supports hot-swapping of drives, which allows drives to be replaced without shutting down the server or workstation.
Benefits of using the Dell Perc H800
There are several benefits to using the Dell Perc H800 RAID controller:
- Increased Performance: The H800 can provide increased system performance by distributing data across multiple drives and caching frequently accessed data.
- Data Redundancy: The H800 can provide data redundancy by storing multiple copies of data across multiple drives. This ensures that data is not lost in the event of a drive failure.
- Hot-Swap Support: The H800 supports hot-swapping of drives, which allows drives to be replaced without shutting down the server or workstation. This can save time and reduce downtime.
- Battery Backup Unit: The H800 has an optional battery backup unit (BBU) that provides backup power to the cache memory in the event of a power failure. This ensures that data in the cache is not lost and can be written to disk when power is restored.
In Summary, The Dell Perc H800 PCI-Express SAS Raid Controller is a high-performance RAID controller that provides data redundancy and increased system performance. It supports SAS connectivity, RAID levels 0, 1, 5, 6, 10, 50, and 60, and has 512MB of cache memory. It also has an optional battery backup unit (BBU) and supports hot-swapping of
