Source element that manages device service requests and manages tasks for processing by a target device and receives responses for the same requests from other target devices. Note: There is currently no data from a SATA IV interface Each t SAS card has a capacity limit of 128 drives and theoretical limit in a system is 6 5.535 units through expanders. In addition, in multiple connections it has the ability to maintain a constant transfer for each deviceĮach SAS port supports up to 16 drives, something that does not happen in the SATA ports, which only support 1 drive. The system itself generates a unique and universal number, so there are no conflicts in communication. These ports have the ability to communicate directly with each other, a great advantage when it comes to data management. In addition, it is highly flexible, so it offers ease when developing large storage systems. While the ports on the motherboard or expansion boards differ slightly, the connector on the storage drive is usually the same.Īs we have commented, this port has been developed to offer a high data transfer. This is because the SAS port is very similar to the SATA port. Note that SATA hard drives can be plugged into SAS ports, but not the other way around. Currently SATA ports also offer this possibility. ![]() This is nothing more than putting or removing a hard drive without having to shut down the system. This port currently achieves transfer speeds of up to 22.5GB / s.Īnother feature of SAS ports is that they allow for the installation or removal of drives hot. These are much more efficient and can better exploit the performance of the SAS ports. It was initially used in special mechanical hard drives that supported between 10.000RPM and 15.000RPM, or what is the same, almost twice the speed of rotation of a commercial hard disk.Ĭurrently the market is already starting to stop using mechanical hard drives, moving to solid state drives. Mainly this type of connection is used in servers, where high performance is required and there are usually many storage units.įor this type of connection there are special storage units with advanced features. The great advantage over other types of connectors is that the data transfer interface is done in series. It is sought with this type of connection to offer the highest possible transfer speed between devices. Promotion: Dell, NEC, Texas Instruments.Main: Fujitsu, Hitachi, IBM, Western Digital. ![]()
