Sas Raid Controller Cables

Raid 0 requires a minimum of two drives.

Sas raid controller cables.

Raid 1 provides redundancy by writing identical data to two drives. A sas expander is a module that allows a sas controller card to use more sas sata drives than it would be able to use on its own because of the limited number of sas connectors on the card. A typical sas card may have just one or two connectors on it and on its own would only be able to support up to four or eight drives. The dell perc h730p mini mono 7h4cn raid controller will not physically fit on the system board of the dell r720xd.

My poweredge t130 is configured with 2 2tb sata drives in a raid 1 mirror using the dell s130 software controller. The dell pec h730p x4ttx raid controller may fit in one of the pci e slots but will require sas cables with mini sas sff 8643 connectors. Raid 1 prevents data losses. I am thinking about purchasing a dell perc h330 raid controller to increase my mirrored disk performance.

This controller is also not supported on the r720xd. In computing serial attached scsi sas is a point to point serial protocol that moves data to and from computer storage devices such as hard drives and tape drives sas replaces the older parallel scsi parallel small computer system interface usually pronounced scuzzy or sexy bus technology that first appeared in the mid 1980s sas like its predecessor uses the standard scsi command set.

The disks work as a single partition and there s no data redundancy with the raid controller cards. I have called dell support dell sales and had multiple dell online chats. Cables tested and approved to ensure a successfully deployed storage solution.

Raid 0 also called disk striping improves write and read speeds by splitting data across different disks.
