Description
Product Overview of 614988-B21 HP SCO8E
The HP 614988-B21 is a host bus adapter (HBA) that provides connectivity to SAS or SATA storage devices through a PCI-E X8 interface. The HBA has eight ports and supports data transfer rates of up to 6 Gbps. This HBA is designed for use in low profile servers, and it can support up to 256 SAS or SATA devices through the use of expanders.
The Role of SAS and SATA
SAS (Serial Attached SCSI) and SATA (Serial ATA) are two types of interfaces that are commonly used to connect storage devices to servers. SAS is a high-speed, high-performance interface that is designed for use with enterprise-class storage devices. SATA is a lower-cost, lower-performance interface that is designed for use with consumer-grade storage devices.
Both SAS and SATA use a point-to-point architecture, which means that each storage device is connected directly to the HBA. This allows for high-speed data transfers and provides a more reliable connection than traditional parallel SCSI interfaces.
PCI-E X8 Interface
The HP 614988-B21 uses a PCI-E X8 interface to connect to the server. PCI-E (Peripheral Component Interconnect Express) is a high-speed serial bus interface that is used to connect hardware components to the motherboard. The X8 designation refers to the number of lanes that are used to transfer data. An X8 interface provides eight lanes of communication, which allows for higher data transfer rates than a lower lane count.
Low Profile Design
The HP 614988-B21 is designed to fit in low profile servers, which are smaller than standard servers. Low profile servers are often used in data centers where space is at a premium. The low profile design of the HP 614988-B21 allows it to be used in these types of servers without taking up too much space.
Expandability
The HP 614988-B21 can support up to 256 SAS or SATA devices through the use of expanders. Expanders are devices that allow multiple storage devices to be connected to a single port on the HBA. This allows for greater flexibility and expandability when using the HBA in a SAN or DAS environment.
Benefits of Using the HP 614988-B21
The HP 614988-B21 offers several benefits for users who need to connect SAS or SATA storage devices to their servers. Some of the benefits of using this HBA include:
High-Speed Data Transfers: The HP 614988-B21 supports data transfer rates of up to 6 Gbps, which allows for fast access to data stored on SAS or SATA devices.
Expandability: The HBA can support up to 256 SAS or SATA devices through the use of expanders, which allows for greater flexibility and expandability when using the HBA in a SAN or DAS environment.
Low Profile Design: The HP 614988-B21 is designed to fit in low profile servers, which allows it to be used in data center environments where space is at a premium.
Reliability: SAS and SATA interfaces are designed to be more reliable than traditional parallel SCSI interfaces, which can help to reduce the risk of data loss or corruption.
Compatibility: The HP 614988-B21 is compatible with a wide range of operating systems and storage devices, which allows for greater flexibility when designing storage solutions.
