4 Storage RAID SCSI SAN Fiber Channel iSCSI

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.

7 RAID Disk Configuration Striped Set RAID 0 Mirror Set RAID 1 Stripe Set dedicated parity RAID 3 & 4 Stripe Set distributed parity RAID 5 Stripe Set distributed dual parity RAID 6

8 RAID Disk Configuration Striped SetMirror SetStriped Set & Mirror Set Striped SetMirror SetMirror Set & Striped Set + + = = RAID 0+1 RAID 10

9 Why RAID 0+1 or RAID 10 XXXXXX Loss of RAID High Data Transfer PerformanceVery High Reliability combined with High Performance

10 SCSI S – Small C – Computer S – System I – Interface

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

14 SAN S – Storage A – Area N – Network

15 What is a SAN An architecture to attach to remote computer storage devices Disk Arrays Tape Libraries Optical Jukeboxes SANs often utilize a Fiber Channel or iSCSI fabric topology

16 SAN Configuration for File Servers

17 SAN Configuration for Exchange

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

20 Terminology Node Cluster Service Quorum Resources Groups Virtual Server

21 Active / Passive

22 Failover

23 How we are Configured at Grey
