Description
Product Information of 729554-001 HPE H221 PCIE 3.0
The HPE 729554-001 H221 PCIE 3.0 SAS Host Bus Adapter is a plug-in card that provides a high-speed SAS (Serial Attached SCSI) interface for connecting internal and external SAS storage devices to a server. The card has a PCI Express 3.0 interface, which supports high-speed data transfer rates of up to 8 GT/s (gigatransfers per second) and is compatible with PCIe 2.0 slots. The adapter is designed for use with HPE ProLiant servers, but it can be used with other servers that support PCIe 3.0.
SAS Interface and its Advantages
SAS is a high-speed, serial communication protocol that is used to connect storage devices such as hard disk drives (HDDs), solid-state drives (SSDs), and tape drives to a computer system. SAS is designed to provide faster data transfer rates, greater reliability, and better scalability than its predecessor, SCSI (Small Computer System Interface).
One of the main advantages of SAS over SCSI is its higher data transfer rate. SAS can transfer data at speeds of up to 12 Gbps (gigabits per second), while SCSI has a maximum speed of 640 MB/s (megabytes per second). SAS also supports longer cable lengths, up to 10 meters, which allows for more flexible storage configurations.
PCI Express 3.0 Interface
The HPE 729554-001 H221 PCIE 3.0 SAS Host Bus Adapter has a PCI Express 3.0 interface, which is the latest version of the PCI Express standard. PCIe 3.0 provides a higher data transfer rate than PCIe 2.0, which was the previous version of the standard. PCIe 3.0 has a maximum data transfer rate of 8 GT/s per lane, while PCIe 2.0 has a maximum data transfer rate of 5 GT/s per lane.
The HPE 729554-001 H221 PCIE 3.0 SAS Host Bus Adapter has eight SAS ports, two of which are external. The external ports allow you to connect SAS storage devices that are located outside of the server chassis, such as an external hard drive enclosure.
Compatibility
The adapter is compatible with a wide range of operating systems, including Windows, Linux, and VMware. It is also compatible with a variety of server platforms, including HPE ProLiant Gen8 and Gen9 servers, as well as servers from other manufacturers that support PCIe 3.0.
Summary, the HPE 729554-001 H221 PCIE 3.0 SAS Host Bus Adapter is a high-performance storage interface card that provides fast and reliable connectivity for SAS storage devices. With its eight SAS ports and external connectivity, it allows for flexible storage configurations that can meet the needs of a variety of applications. The card’s compatibility with a wide range of operating systems and server platforms makes it a versatile choice for any organization that requires high-speed SAS connectivity.
