  1. The basics ofStorageMicrosoft clusteringGrey File services

  2. Storage • RAID • Types of RAID • Protocols • SAN • Microsoft Clustering (MSCS) • What is clustering • Terminology • How we are configured at Grey • Grey File Services • PC and Mac access

  3. Storage • RAID • SCSI • SAN • Fiber Channel • iSCSI

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

  5. 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.

  6. 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

  7. RAID Disk Configuration + = RAID 0+1 Striped Set Mirror Set Striped Set & Mirror Set + = RAID 10 Mirror Set Striped Set Mirror Set & Striped Set

  8. Why RAID 0+1 or RAID 10 High Data Transfer Performance Very High Reliability combined with High Performance X X X X X X Loss of RAID Loss of RAID

  9. SCSI • S – Small • C – Computer • S – System • I – Interface

  10. What is SCSI • A set of standards • SCSI most common uses • Hard Disks, Tape Drive and other Devices • SCSI interfaces

  11. 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

  12. 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

  13. SAN • S – Storage • A – Area • N – Network

  14. 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

  15. SAN Configuration for File Servers

  16. SAN Configuration for Exchange

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

  18. 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

  19. Terminology • Node • Cluster Service • Quorum • Resources • Groups • Virtual Server

  20. Active / Passive

  21. Failover

  22. How we are Configured at Grey

  23. Grey File Services • CLFS-777-01 • ExtremeZ-IP • PC and Mac Access • AFP / SMB • PC = \\CLFS-777-01\ShareName • Mac = MacShare, FileShare, FileShare2, & FileShare3

  24. File Servers • Virtual Server • CLFS-777-01 • IP Address – 172.18.1.52 • Physical Server 1 • FS-777-CL01 • IP Address – 172.18.1.50 • Physical Server 2 • FS-777-CL02 • IP Address – 172.18.1.51

  25. ExtremeZ-IP

  27. AFP / SMB • AFP • Apple Filing Protocol • SMB • Server Message Block

  28. PC Access to File Shares • \\CLSF-777-01\ShareName

  29. Mac Access to File Shares • Search Domain and DNS Servers • GGG.GREY.GLOBAL • 172.18.1.22 & 172.18.1.28 • Server Names and IP Address • MacShare • 172.18.1.120 • FileShare • 172.18.1.121 • FileShare2 • 172.18.1.119 • FileShare3 • 172.18.1.118
