5. RAID R – Redundant A – Array I – Inexpensive (or Independent) D – Disks

6. Types of RAID RAID 0 "Stripe Set" RAID 1 "Mirror" RAID 3 & 4 "Stripe Set dedicated parity" RAID 5 "Stripe Set distributed parity" RAID 6 "Stripe Set dual distributed parity" RAID 0+1 or RAID 10 "Nested RAID Definition of Parity: If a single drive in the array fails, data blocks and a parity block from the working drives can be combined to reconstruct the missing data.

12. What is Fiber Channel a gigabit-speed network technology primarily used for storage networking Fiber Channel signaling can run on both twisted pair copper wire and fiber-optic cable There are three major Fibre Channel topologies: Point-to-Point Arbitrated loop Switched fabric

13. What is iSCSI A protocol that allows clients (called initiators) to send SCSI commands to SCSI storage devices (targets) on remote servers. Uses TCP/IP (typically TCP port 3260) iSCSI needs Initiator Host Bus Adapter (HBA) Target

18. Microsoft Clustering (MSCS) What is a Cluster Terminology How we are configured here at Grey

19. What is a Cluster Microsoft Cluster Server (MSCS) is software designed to allow servers to work together as computer cluster, to provide failover and increased availability of applications Minimum number of nodes in a cluster is 1 Maximum number of nodes in a cluster is 8 Need shared disk San or NAS storage Windows 2003 Enterprise Server
