Description
Product Overview of the 4-Ports Int SAS Controller
The HPE 726793-B21 Smart Array P246BR is a SAS controller with 4 internal ports and a 12GB/s transfer rate. It has 1GB of flash-backed write cache (FBWC) to improve performance and data reliability. In this article, we will discuss in detail the features and benefits of this product.
SAS Controller Overview
SAS (Serial Attached SCSI) is a computer interface used to transfer data between devices such as hard drives, solid-state drives (SSDs), and other peripherals. A SAS controller is a hardware component that manages the transfer of data between a computer system and SAS devices.
The HPE 726793-B21 Smart Array P246BR is a SAS controller that provides fast and reliable data transfer between the computer system and SAS devices. It has 4 internal ports that support SAS or SATA (Serial ATA) drives, and it supports up to 64 SAS or SATA devices with the use of expanders.
Transfer Rate
The transfer rate of a SAS controller determines how quickly data can be transferred between the computer system and SAS devices. The HPE 726793-B21 Smart Array P246BR has a transfer rate of 12GB/s, which is significantly faster than SATA’s maximum transfer rate of 6GB/s.
Flash-Backed Write Cache (FBWC)
The HPE 726793-B21 Smart Array P246BR has 1GB of flash-backed write cache (FBWC) to improve performance and data reliability. FBWC is a type of cache that uses flash memory to store data temporarily before it is written to the disk.
By using FBWC, the SAS controller can quickly write data to the cache and then acknowledge the write to the computer system, which improves performance. Additionally, if there is a power loss or system failure, the FBWC can protect the data in the cache by backing it up to the flash memory.
4 Internal Ports
The HPE 726793-B21 Smart Array P246BR has 4 internal ports that support SAS or SATA drives. This means that it can connect up to 4 SAS or SATA devices directly to the controller without the need for additional cables or adapters.
Compatibility
The HPE 726793-B21 Smart Array P246BR is compatible with a wide range of HPE ProLiant servers, including Gen8, Gen9, and Gen10 servers. It is also compatible with Windows and Linux operating systems.
Benefits of the HPE 726793-B21 Smart Array P246BR
The HPE 726793-B21 Smart Array P246BR provides fast data transfer rates and uses FBWC to improve performance. This means that it can handle high-bandwidth applications and large data transfers with ease.
Data Reliability
The FBWC on the HPE 726793-B21 Smart Array P246BR can protect data in the cache in the event of a power loss or system failure. This means that data is less likely to be lost or corrupted during a system failure.
Ease of Use
The HPE 726793-B21 Smart Array P246BR is easy to install and configure, and it supports a wide range of operating systems and HPE ProLiant servers. This means that it can be used in a variety of environments without requiring significant changes to the existing infrastructure.
Cost-Effective
The HPE 726793-B21 Smart Array P246BR is a cost-effective solution for SAS storage requirements. It provides high-performance SAS connectivity and FBWC at a reasonable price point, making it an excellent choice for businesses with limited budgets.
