ADAPTEC 51245 kit

Šestnáctiportový internal SAS controller designed for PCIe interface offers data transfer rates up to 3 GB per second on a single port.The card can connect 256 devices.The advantage is support for booting a possibility to combine SAS and Serial ATA drives which makes it possible to achieve excellent ratio of price / performance.Controller also supports the function of HostRAID (SW RAID levels 0, 1, 5, 6, 10, 50, 60, JBOD).Thanks to support 48-bit LBA can be used discs with a capacity of more than 137 gigabytes.Thanks to support 48-bit LBA can be used discs with a capacity of more than 137 gigabytes.It comes in a kit package.Controller is equipped with an integrated processor 1st2GHz Dual Core RAID.
SAS is the innovative generation of the SCSI increasing the performance of the repository systems and improving their availability.Extends the functionality of parallel SCSI hard disks and one of the main advantages of this technology is the integration of 3.5-inch SAS units with a Serial ATA units in a single device.To connect the disk is used the same cables and connectors for drives with a Serial ATA interface.This option offers exceptional flexibility and scalability.Full-duplex architecture will ensure that storage facilities supplied data to the host system at the same time, when the host system sends commands to other storage facilities.Dual-port architecture allows easy integration type of fail-over.Host systems and storage are connected to two channels and data are constantly available in the event of a failure of some of the components.Other benefits such asdata integrity, reliability and the ability to connect up to 16,256 discs in a single domain.Interface disk with this find, for examplevysokotransakčních in the database and applications for highly available data, but also for archiving data or backups.
