ADAPTEC ASR-4805SAS, 4+8-port SAS RAID (0, 1, 5, 10, 50, JBOD) řadič, PCIe x8, 256MB cache, bulk

Internal osmiportový SAS controller designed for the PCI Express x8 offers transmission speeds up to 3 GB per second.The card can connect eight devices and up to 128 devices using expanderu.The advantage is the ability to combine SAS and Serial ATA drives which makes it possible to achieve excellent relationship price / performance.Newton also supports the function of RAID 0, 1, 5, 10, 50, JBOD and a wide range of functions such as Hot swap, online or increasing capacity optimization drive.It also includes an integrated cache ECC DDR2 256 MB zálohovanou batteries.Newton is available in bulk packages (only card without accessories).

SAS is the innovative generation of the SCSI increasing the performance of the repository systems and improving their availability.It extends the functions of parallel SCSI hard drives and one of the main advantages of this technology is the integration of 3.5-inch SAS units with Serial ATA drives in a single device.To connect the disk to use the same cables and connectors, as the discs with a Serial ATA interface.This option offers exceptional flexibility and scalability.Full-duplex architecture ensure that the data storage equipment supplied 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 accompanied by 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 possibility to connect to 16256 discs in one domain.Discs with this interface find, for examplevysokotransakčních in the database and applications for highly available data, but also for archiving data or backups.
